I had one of these in early 1984 - it cost me £150. I'd just started working, and this was the first really expensive thing I ever bought. I used it for years, and very soon after I got it, stopped using the pre-set everything on it. The Multi-menu meant that you had a programmable drum machine, bassline, etc. I ran it through various effects pedals, and got it to make some nice dark crunchy sounds, which was great, as I was a fan of the 'darker end' of the electronic music spectrum (still am, actually), like Throbbing Gristle, Fad Gadget, D.A.F., Gary Numan, etc. Then I got rid of it. And, hearing it again, I wish I hadn't.
I bought one here in the UK in early 1984, and it cost £150. It's a brilliant keyboard, and once you have mastered the 'Multi Menu' function, with it's programmable drum machine and bassline, I very seldom went back to using the preset sounds. The tape dump worked pretty well, but wasn't very quick. It sounds fantastic if played through effects - I had a load of guitar fx pedals, and an old Tandy (Radio Shack) reverb unit. Alas! When short of cash, I sold the MK-100. Your review makes me want another.
As far as I know, there are no acids coming out from a leaked alkaline or zinc-carbon battery. It's actually potassium hydroxide in the case of Alkaline batteries (which may react to potassium carbonate on the air) or ammonium chloride in the case of older zinc-carbon batteries. Both are pretty strong bases which let metals and electronical components corrode; that's why many people think it's acid. So why is this important? Because you can actually use some household-acids like vinegar concentrate to dissolve the residues of the leakage, even when everything is completely corroded because of the leakage. In case of these battery contacts or springs, you may simply remove them from the case and put them into some household acid for a few hours. You could also use some paper towels and clean "attacked" parts of PCBs using some not-too-strong household acid. Of cource, this will not bring back completely destroyed traces of a PCB, so you should do this, before it happens. Simply scratching the leakage often isn't enough, since there will most likely always be some inivisible residues left. Luckily, in your case the leakage didn't seem to have attacked too much. Sorry, english is not my mother tongue. Hope I could help with this :)
+martravi Good to know. I have done the opposite and cleaned car battery terminals and such with baking soda, since those are actually acid. I assumed the alkaline batteries were too.. but now that I think about it, I guess that's why they are called alkaline batteries. I guess it is a "duh" moment.
I was very surprised as well for a 1983 keyboard. He even said it did not even have a synth chip in it. Although my heart is on the PSR-36 for its synth sound! my favorite chip being the YM2151 of course!
I know that this is an inactive channel now but I just discovered it recently and I have been enjoying all the videos. Too bad he doesn’t post occasionally on this channel as the content is very good. Even though the subject matter is redundant, each keyboard has its own unique sound, quirks and challenges which makes it interesting to watch
I have no keyboard. Never played in my life. Not really like keyes. Still love this channel. Bringing old devices back to life is just soo satisfying :)
Great cleanup job! You are correct that it's not FM. The MK-100 used digital waveform sample based synthesis. However, Yamaha was indeed using FM synthesis back when this came out, just not on their cheaper porasound lineup. For example, the MK-100 came out the same year (1983) as the most famous FM synth of all time, the DX7. Portasounds started using FM around 1985.
I've been watching your channel (as well as your main channel) for some time now. I know this is an old video, but I just wanted to let you know, I love watching the cleaning/repairing process of these old machines. It's kind of relaxing just knowing that something was wrong and now it's right! Thank you for your work, keep it up!
Pro-tip: Vinegar (acid) makes a wonderful cleaning agent for leaking alkaline (base) batteries. It's best to remove the batteries first and properly dispose of them. Putting leaking batteries directly into vinegar could lead to volatile results. Always take caution when mixing acids and bases.
Wow, yeah, 7 bucks for this little beauty is a great bargain! Yes, a keyboard's only really yours once you've cleaned it. XD The MK-100 is one of my favourite keyboards from that time. I was happy to find it for 40€ ten years ago :) Lovely organ sound, great percussion, and loads of features that make this a real little workstation (rhythm sequencer, bass sequencer)... Tape storage was by the way noot that common feature for home keyboards with more complex sequencers in the early 1980s. Casio PT-30/31/50, CT-7000 all had it, even the CZ-5000. And yes, the first home keyboard with FM seems to be the high-end PS-6100 from 1984, with "standard" PortaSounds following in 1985. But... when's your in-depth review coming? ;)
You're an awesome human being with astonishing intelligence, charisma, talent in a multitude of facets, and you appear to have a fantastic happy life, and family. Couldn't have happened to a more deserving man. Thank you from the bottom of my heart for all your content on both your channels.

Awesome video, man; thank you. That really is an interesting little keyboard; I wouldn't have assumed that the sound-design capabilities would go so deep, from the look of it.
This has some sounds I really like I bet this is one of your happiest findsI really appreciate that you restore old keyboards and show us what they can do. This one was especially interesting. Keep up the fine videos!
I love your vids 8 bit guy youre an awesome youtuber and a father i seen some of your family vids and youre so informational on technologies. you make me wanna collect old stufff and fix them myself.
4:30 ‘it’s actually pretty amazing’. I don’t know whether David always thinks thinks this and follows with ...’for a cheap 1980’s keyboard’ or whether he genuinely thinks it is amazing full-stop - even in 2019! I think a part of him never left the 80’s.
A simple google query gave me the original price of this keyboard. Are you ready? Yamaha PortaSound MK-100 Released 1983 Original Retail $299 Paid $7? Quite a good deal I must say. I think you'd easily agree for $80, especially considering the fact that these keyboards are not easy to find. Proof link for price:www.sonicstate.com/synth_reviews/yamaha_mk-100/
I have seen a custom rotating selector like that before. Back when I played the organ, it was on the late 1980s Baldwin home organ in my (parents) house. The features on the Baldwin were different, but the rotating selector was very similar.
The Rolodex-style Multi-Menu was originally used in the Yamaha Electone MC/MR series home organs, then the HS and HC/HE series. Both a great way to save space and a horrible idea. It made playing the Electone a much more complicated task.
+OnKz I have never seen something so unique...I used to have a good chunk of rare things, but what they were were mostly unrelated to this topic or not from this era. Some of the rare items I still have, for example, are an original PC-platform copy of Halo CE, original copy of Midtown Madness 3 on original Xbox, and more recently, a hand-me-down 80's Saskatchewan Roughriders Shain-branded windbreaker in next to mint condition. The closest I can come to this era with ownership of anything electronic is a random MS-DOS era RAM stick, previously belonging to a computer my brother had for about a week before it sparked, let a puff of smoke out the ventilation holes, and never worked again. (can't remember what type or size this RAM stick is, but it uses flat pins like an NES cartridge as opposed to actual pin-shaped pins yet.)
8-Bit Keys I got the drum machine to play the drum line of Blue Monday. The keyboard has a really wierd and uninituitive quantization which makes it tricky to program. Holding Cancel and one of the tracks clears it, and there's a two bar, probably 1/16th accuracy loop.
I have one of these too. There's a sequencer on it as well though it's limited to a very small number of notes. One of my favorites and it certainly sounds very nice. I never could get the cassette saving and loading function to work though.
+Pierre Fontaine Maybe you could help me figure out how to use the custom drummer. I want to be able to manually play the drums, but can't quite figure out how.
+8-Bit Keys I haven't plugged this one in for a few months but my recollection is that you can't play the drums manually. You load up a drum pattern, hit "candel" and hold down the key assigned to that drum sound for the entire measure. That will erase that drum part. You can then play a new pattern for that individual part. You need to do that for all 5 drum parts. It's tedious but it works. The manual for this keyboard is still available on Yamaha's website which helps tremendously!
That's really cool to see the multi-menu on a smaller keyboard. Saw the same sort of multi-menu arrangement on a Yamaha Electone organ, specifically the model MC-200T. The organ was pretty neat, but I thought the draw of it was the multi-menu, so I guess a wide range of Yamaha keyboard/organs from that time had it.
+Marcos Aruca I recently discovered this keyboard is basically the same as the more common PSS-450, which lacks a lot of the advanced features that most of us would never use anyway. It even looks very similar, just missing a few buttons. So if you want one, that may be an easier alternative to find.
The PSS-450 is indeed the same "base" keyboard, but it lacks so many features that in the end it may not be worth it. Not only it lacks the synth section, but also all of the custom options (custom drummer, bass lines, accompaniment, dual voice, etc), trio mode, sequencer, transposer and even the tremolo and vibrato effects. It's a very basic keyboard, with only the main MK-100 voices and rhythms (including the three or so variations for bass and chords), just the essential effects (sustain and stereo symphonic/chorus) and duet mode. I'm not sure how much they cost over there in good ol' USA (and good ol' all over the world), but it would be wise not to pay much. It has some lovely sounds, but it's very basic. The MK-100 really has it all! Thanks for all your videos, by the way. I really appreciate your channel! PS.: A few days ago I asked here in the comment section if anyone was willing to sell a MK-100 so I could use it in my lo-fi projects and thankfully I found not only one but two of them! I'm really happy. I've been looking for it for a long time.
Yeah. Thanks for the redundant information. Actually, I'm a little pissed that I found the information first, but then you get all the likes. But at least David replied to my comment.
Interesting to see the restoration/cleaning process. I picked up a Yamaha PSS-480 on eBay in December, and although it looks rather clean, maybe I should do the same...
Really cool keyboard! I know some of Yamaha's Electone organs had that Multi-Menu unit. Also the previous owner made a huge mistake; mixing battery types.
+NLind It seemed to get plenty of use tho, around breakfast time I would guess!! It came with a blank headphone plug for shutting off the speakers when outputting to an amp via phono sockets.
Having a keyboard with interchangeable waveforms and being able to customise them is neat... Also I noticed button number 12 at 6:17 when selecting a waveform. I don't know if it's unused or has a function for the waveforms.
You're right about FM synthesis. The first FM Synthesizer was the Yamaha DX1. Only 140 of those made and they are quite rare. FM synthesis back in those times was reserved for pro level synthesizers such as the DX1, DX5, DX7, DX21, and the list goes on.
Wow, Toshiba should use that vintage logo for a year, maybe for their next major anniversary. You should submit a photo of those vintage Toshiba chips to the Toshiba Wikipedia page.
Great video, man, I'm always looking forward to your uploads when deciding whether or not to buy a specific keyboard. In a previous video you mentioned you were planning on making one about FM synthesis. If you're interested, the manual for a Yamaha PSS-480 has a fantastic and simple explanation, and the keyboard itself is very versatile, but not much different that the 570.
+Hearing Required OK, thanks. Yeah, I've been struggling to understand how FM works well enough to explain it to other people. I mean, I have a general idea. But that isn't good enough.
I love, love, love, LOVE videos like this! I like seeing the whole process of how you bring things to life in an interesting way. Very interesting keyboard and in some ways maybe sounded more like the Casio models of that era? Hard to say but it definitely does not sound like FM.
+EgoShredder I keep looking for some good deals on some Casio keyboards of that time period but haven't come across any yet except on ebay for too much money.
Does the data to tape use FSK or something like that? If it's simply audio, you could even record to a digital recorderon your computer line in and use it that way. Just keep the sample rate and word length for enough granularity.
7:38 I am trying to find this music show here but I am not able to find them I tried to find the audio blocks website and it just sends me to the story blocks website
Any chance that someone would have the actual owner's guide/manual for this in PDF format? And I mean the actual keyboard manual (the one in blue and white, which has a picture of the MK on the front page and says Yamaha Portasound MK-100) , not the multi-menu one. I recently got this fantastic piece of instrument (FINALLY! YAY), and it seems that the only manual available online is the multi-menu guide. Of course the multi-menu is the most interesting aspect of the instrument, but it would be nice to have the actual keyboard manual as mine didn't come with any of them and I would like to have it printed. I never understood why people throw away the manuals, by the way (and, to a certain degree, the boxes)... Even when they're basic, it sort of feels like something is missing if they're not there. Thanks in advance! :)
It cost £200 back in 1983, yes I'm British, I still have my MK-100 in the box with instructions, it was my first keyboard and it became part of the family.
I don't know why it's so satisfying to watch you clean the keys.

Having a keyboard with interchangeable waveforms and being able to customise them is neat... Also I noticed button number 12 at 6:17 when selecting a waveform. I don't know if it's unused or has a function for the waveforms.
You're right about FM synthesis. The first FM Synthesizer was the Yamaha DX1. Only 140 of those made and they are quite rare. FM synthesis back in those times was reserved for pro level synthesizers such as the DX1, DX5, DX7, DX21, and the list goes on.
Wow, Toshiba should use that vintage logo for a year, maybe for their next major anniversary.
You should submit a photo of those vintage Toshiba chips to the Toshiba Wikipedia page.
This is a really neat keyboard, I'd love to hear a follow up composition on it!
I love your videos, dude. Great work!
Holy shit that thing is amazing! If only I could find one for sale somewhere..
because of this channel, i have a psr 32, pss-470, pss-270. i will be getting a psr-36 now i want to get one of these lol
Good vintage keyboard probably one of the better ones yet.
Great video, man, I'm always looking forward to your uploads when deciding whether or not to buy a specific keyboard.
In a previous video you mentioned you were planning on making one about FM synthesis. If you're interested, the manual for a Yamaha PSS-480 has a fantastic and simple explanation, and the keyboard itself is very versatile, but not much different that the 570.
+Hearing Required OK, thanks. Yeah, I've been struggling to understand how FM works well enough to explain it to other people. I mean, I have a general idea. But that isn't good enough.
Yamaha did start using FM when this thing came out, the DX7 came out in 1983. From the sounds of it, it's only two operator
How didn't I notice this channel before?! This is awesome XD I subbed
Awesome little keyboard: it's like an ancestor to Teenage Engineering OP-1 :)
I love, love, love, LOVE videos like this! I like seeing the whole process of how you bring things to life in an interesting way. Very interesting keyboard and in some ways maybe sounded more like the Casio models of that era? Hard to say but it definitely does not sound like FM.
+EgoShredder I keep looking for some good deals on some Casio keyboards of that time period but haven't come across any yet except on ebay for too much money.
The 8085 was (and still is on some cases) very popular for integrated stuff like that due its "microcontroller" like powers.
Does the data to tape use FSK or something like that? If it's simply audio, you could even record to a digital recorderon your computer line in and use it that way. Just keep the sample rate and word length for enough granularity.
+videodistro That's my plan.. I'm going to try using Audacity to record and playback.
This video is so old, TH-cam doesn't even recognize 720p as "high definition" anymore 💀
Found an add in a Dutch newspaper from 1986 and it retailed here around 600 US Dollars...
you should look into an auto-detailing brush - it looks like a 1 inch paint brush cut to about a half inch in height with a crew-cut styled bristling.
7:38 I am trying to find this music show here but I am not able to find them I tried to find the audio blocks website and it just sends me to the story blocks website
oh and by the way : 07:20 - The Yamaha MK100 carries an RRP of £329 including VAT, Source EMM 07/84
When can we look forward to a full review/demo?
What a nice little piece of synthesizer :)
It is indeed a piece of synth.
A very cool keyboard!
I'm curious as to why you didn't completely disassemble and wash the front panel, as you have done for other keyboards.
This before picture perfectly represents what my school food looks like.
Yahama makes good stuff, even at their worst. Now I want one!
Thanks for the Ultima cameo!
Any chance that someone would have the actual owner's guide/manual for this in PDF format? And I mean the actual keyboard manual (the one in blue and white, which has a picture of the MK on the front page and says Yamaha Portasound MK-100) , not the multi-menu one.
I recently got this fantastic piece of instrument (FINALLY! YAY), and it seems that the only manual available online is the multi-menu guide. Of course the multi-menu is the most interesting aspect of the instrument, but it would be nice to have the actual keyboard manual as mine didn't come with any of them and I would like to have it printed. I never understood why people throw away the manuals, by the way (and, to a certain degree, the boxes)... Even when they're basic, it sort of feels like something is missing if they're not there.
Thanks in advance! :)
Hi, do you still need it? I believe I have what you need. :)
Did you acquire this owner's guide in pdf format? I can still only find the multi-menu one online.
Not acid, electrolyte, more or less harmless, its even used in a lot of candy (ammonium chloride). Love your vid's, great work!
wow you play some good music! I would love to learn how to play and buy one of those not so famous keyboards with a computer built into it
YA3256 is a Yamaha DX27 ROM, also used in Yamaha DX100
04:57 wtf was that song? so familiar but kind of faded away over the years
Jurassic Park.
thanks. memories brought back lol.
The moment you started playing it i was actually thinking about the jurassic park theme :D (Nice job by the way :) )
Yeah I was also thinking Jurassic Park
is it weird that I never watched Jurassic park yet knew where the music was from?
usually i don't care of keyboards but u make the subject interesting :D
+Miiick3y Well, that's my goal.
Man this device is so cool!
What was the song you played on violin part? 5:06
Apparently it's the Ultima Online title theme, Stones.
i think its the forest theme on ultima online i play it all the time
That is a great keyboard. Nice sound too.
It cost £200 back in 1983, yes I'm British, I still have my MK-100 in the box with instructions, it was my first keyboard and it became part of the family.
The track used during the repair sounds like a track used in a Yatzhee PC game from the late 90's.
Any plans to review Casio MT 65, or others like MT 68, MT 70, etc?
+Rocky Durand Yes, actually. I plan to do some of the Casio MT series. But it might be a few months.
He’s going to give this keyboard a little love don’t y’all think
so, over 3 years later, where's the multi-track performance...?
Furniture polish after cleaning is also another good move.
That costum waveform is sweet
Any chance of covering the Stylophone, or is it too uninteresting as a device to cover?
+xnamkcor X maybe some day.
+8-Bit Keys i find that if you ever do decide to cover the stylophone, you could include other similiar oddities like the otamatone aswell
5:08 I've learned how to play that song today, but I do not know what the song name is.
