Just an FYI, The board I sell on Tindie at: www.tindie.com/products/projectspeccy/recreated-multiface-128-bare-board/ has the small revision of a right angle touch switch option to make it more like the original device. The solder mask is in ProjectSPECCY.com red as well. Great video Mark!
Hi Steve, i have build that MF128 also but can't get it to work on a 48K or on a 128K +2 grey. That is WITH additional cards plugged in (like ZX-VGA-JOY) pressing the NMI button just let the screen flash for a second and resets or blocks the Spectrum. It only works fine on a Harlequin in 128k and 48K mode with additional cards. I have added a expansion board at the back of the MF128 + diode and placed it as first in the row, but no luck.

With solder, your mileage may vary. However, I use Multicore. It's more expensive but consistently good. I've spent too much time in the past faffing around with bad solder.
I had a Multiface 128 for my Toastrack 128K back in 1986. It was the only way to get games on to my Opus Discovery 3.5" floppy drive. Wish I still had them all!
Thanks for the tip on that orange-reeled solder Mark! I bought two reels of it in different thicknesses a while ago and haven't got to them yet... Looks like they'll be going in the bin!
tip: my MultiFace 128 has 2 8k ram piggy backed and a switch to disable rom and switch to ram for a 64K spectrum. In spectrum rom a routine to copy rom to 16k MultiFace ram. Then you can poke in rom.
Nice job Mark - just sub'd. I used to have an old school MF128 clone that looked like it was cobbled together in the 80s. This SS board is excellent although it would be even better IMO if the edge connector attached to the other side of the PCB so you could see the ICs when it's attached to your Speccy.. "That's Numberwang!"
@@MarkFixesStuff it seems ok to be fair, i brought some cheaper 1mm stuff and it was like soldering with custard so went back to this... i was also using cheap solder tips then i tried some real hakko ones .. the difference can not be overstated
I have the Multiface One loved it then I got the Multiface 3 for my +3 was not so happy to find i could not load my games from disk without having the Multiface 3 connected and having to press the button so the games would load. Pressing the button downwards would sometimes causes the Spectrum to crash. So for me the button would of been better fitted where it is on the clone board as you could support the Multiface unit while pressing the button between your finger and thumb. Nice one Mark is it me or are those gummy bears putting on weight. ?

That is WITH additional cards plugged in (like ZX-VGA-JOY) pressing the NMI button just let the screen flash for a second and resets or blocks the Spectrum. It only works fine on a Harlequin in 128k and 48K mode with additional cards. I might check if it works on the grey if i use the composite output.
First thing to check is if the CPU is OK. Sinclair cheaped out and used lower cost parts that OFTEN had a weak or missing m1 line signal. It was a problem even back in the 80s. Swap in a known working Z80 and see if it works. It is common!
@@MarkFixesStuff Hi Mark. Weird thing is, the NMI works fine with a DivMMC for example. If i connect the MF only and use the VGA (mod) output, then it works.
I am not sure what country you reside in. The best solder you can buy is KESTER SOLDER 24-6040-0027 Wire Solder. Which is 0.031" in diameter. It might be more expensive than the solder you just bought, but the quality is unsurpassed. If you have country restrictions regarding the use of lead in the solder then you would of course have to go with the lead free solder. Again buy the KESTER brand. Can't go wrong with that. I never go with the no clean stuff. You always have to clean it anyway so why waste extra money on that feature.
Kester keeps coming up over and over again. It is expensive but I’m really compelled to get some now. I’m in the UK so the restrictions on leaded solder are “not for commercial sale” but I can buy it. The no clean flux I use is just my favourite because it works so well, and although I need to clean it anyway, it’s easier to get off than some of the others which can be like toffee! Thanks for watching and taking the time to comment. It’s really helpful stuff!
I hope you have super ventilation when using the toxic China stuff. Could be fun to see what that solder is realy made of, proberly filled with lead. 😏

Your soldering iron doesn't look hot enough! Set to 350 and see if there is any difference. If not, it's your solder. I use only Kester lead solder from Digikey. It's a whopping $60 USD a role. This may sound expensive and not lead-free, but there is a reason companies use good quality solder, instead of cheap Chinese imitations. Working with a good solder, makes soldering a real joy. I would pull my hair out, if my solder looked like yours. Also, nothing beats real flux. Forget non-clean and all that jazz. They all leave residue. I hate residue, so IPA to the rescue...
I’ll try whacking the iron up to 350 degrees but it’s just crap solder. I was actually given it for free by a vendor and I’m waiting for my decent solder to turn up. Unleaded solder is dreadful. I tend to use leaded myself, especially because vintage machines already have leaded solder on the boards. To be honest, using the bad solder was just a silly distraction for the video.
@@MarkFixesStuff It's probably made of ammonium chloride to make it water soluble. The best are the natural rosin for soldering. I like the pine smell. Not like some horrible chemical. The amount of flux and quality of flux inside the core of solder is important and often the first thing they skimp on. I always use some flux. Just as I would when doing plumbing with copper pipes. Soldering without any flux whatsoever, is impossible. Solder just won't flow and clumps up at the tip of the iron.

At least the solder wasn't lead free. Someone at work thought if the reel is green it is. Aweful stuff.
I’ve actually still got one of these in my attic somewhere 😊

Solder-wise, I'm kinda sold on Kester... MG Chemical is alright but definitely not quite as good, at least for me.
I am now a Kester convert! Nearly £50 here for a 1lb roll but worth it. Thanks Charles!
I really appreciate that this was designed with the edge connector on the OPPOSITE side from the rest of the components. Very cool.

OCD on the caps yet resistors be like.... Bah!
Impatience > OCD
I had one of those on my CPC 6128. I remember the green and red buttons lol.
I had the multiface for the spectrum plus 3 great for saving games in memory to disk back in the day .
Great content. Good quality solder = less drama for sure!
100 percent true. Sometimes it's nice to show that not everything is perfect every time in these videos!
Another great video. I had a MF2 for my CPC 6128 in the day. Right, now for “Jason Gets Jabbed!”

I've bought some Kester now!
I used a friends Muliface 128 to copy games onto Microdrives in the 80's. I've got my own Multiface now, but my Microdrive carts have corrupted. LOL.
Probably need refelting now mate.
Nice vid, i still need to populate my board :)
Aren’t these bypass capacitors, if I am not wrong the coupling capacitors are found in amplifiers.

In spectrum rom a routine to copy rom to 16k MultiFace ram. Then you can poke in rom.

This is such a wonderful project. What's the best place (UK) to get the logic IC's from?
To be honest, right now you will need to grab them where they are in stock. I used CPC Farnell and ebay.
@@MarkFixesStuff i see what you mean.. 74S260N's seem hard to find - damn
you should get yourself some of that rad Stannol S-Sn60Pb40 solder
I need to try that one. I bet it’s expensive lol
@@MarkFixesStuff cant get it from the manufacturer anymore, only old stock from other people. thats how i got my 2 spools of solder
ohh im using that same solder... except it's .6mm and on the bottom it says "JINHU" not "KAINA"
Might be completely different. How do you find it?
