Excellent music!

this guy sounds like scary voice from the old macintosh.

Just seen your video. Thanks. I would love you to show a video all about the different registers and how they work. Perhaps with a a simple program.

Excellent project, could you give me the plans to make the PCB and the necessary components, so I can make one? Thank you so much

Come back Ralf, at least one person misses you!

Gratuliere 👏

Emmm…which ROM voice card is “RHODES”on? I couldn't find this voice on many official Yamaha ROM voice cards😢

I worked with PDP 8 and PDP 11 at Harwell in the early 70's - they were used as front end processors to control Neutron Spectrometers. A PDP8 was used as a command processor/ multiplexer for end users of the IBM system 360 mainframe. In those days end users were lucky if they had a teletype. These days the AVR 8 bit microcontrollers I use to control the dome of my astro observatory have much more memory, dozens of registers, internal oscillators and 20Mhz cpu clock if you need it, also 500 times smaller and cost next to nothing..... You could use one to simulate a PDP11 - now there's an idea -where's my box of awful red, white and black plastic....thanks for posting, - a nice nostalgia project :) :)

Thank you for the video. What should be the properties of an alternative diode?

PIP baby.

Very nice job. I might 3d print some guides for the LEDs if I was building this kit. Plus perhaps some 3d printed mounting parts with brass heat-set nuts instead of wood scraps.

When I was in high school a few of us were allowed to go over to the Junior College and learn programming on the PDP-8. Later I attended that Junior College and worked directly with that PDP-8 and an HP-3000. Then I went to college and worked with the PDP-11 and the CDC-6400. Later I built systems with LSI-11's and MicroVAXes and onward from there. Fun times and great memories. Either a PiDP-8 or PiDP-11 would be interesting to play with, especially the 11.

Hey you have a real brain man 👍

What operating systems can this run? I know the piDP-11 has a bunch of UNIX variants, but does this?

I had one as a kid and loved that thing!!! wish i knew what happened to it..

how do I sequence mine to say stuff

Me too blinking lights & music do you have a good DMX SETUP

Oh... "Colossus - The Forbin Project"... thanks for the title of that movie.... I had seen it as a kid in the 80's so wanteed to see it again§...

Man, your DX7 looks nearly new. Where did you get that one?

d-10 for 50 bucks? where are you getting these prices, crazy guy?

How your project goes?

i did short my arduino nano, and i change the diode with 1N4004 type the board is on, but not detected anymore on my PC is there any solution?? pin 3.3v doesn't have any power, so on IC CH340G also

Hallo, schön gemacht. Möchte ich auch machen. Leider reagiert der Schöpfer des Emulators auf Anfragen, Bestellungswünsche SEHR langsam, imo gar nicht. Würden sie die Hardware Dokumente (Stand 2015, eigentlich auf Anfrage von seiner Google-Speicher) bereitstellen? Wäre schön. Die Hardware auf dem Frontpanel-PCB ist nicht so schwer. Ein Paar Widerstände, Schalter, LED, Verbinder, UDN LED-Treiber. Ausserdem ist das Panel recht gross geraten. Das Briel pcb (Altair) war deutlich kompakter. K.A. , warum alle ein Geheimnis daraus machen. LG

These are over 175.00 uk plus shipping now

Nice video ! I have about 70 unused packaged DX 7 ram cartridges made by a third party Music store chain in japan back in the mid 80s They are in perfect condition unopened in original packaging .. I looked for an email address on your profile to contact you but could not find it.

Man you just... for real. It is nice synthesizer if you know how to operate sound . Sorry

In Japan it also costs 5 000 yen and it's not even that pricey =)

Fantastic! I will try to do the same with my Yamaha RX11

wonderful I'm very interested! Could you please tell me the pcb data of kicad and the parts you used?

looks like you totally missed the "vocaloid" chip-tune vocoder aspect of the miku, with much more playability than with the Korg miku stomp pedal!

Nice sound, nice improv.

I just knew about pocket miku, but now price is hiked. I think yours is the best video, even used system exclusive message to enter extra Japanese lyrics. Good work, Subbed.

go listen to "streamers" by wave racer and you'll see what type of music this thing was made for :) i wouldn't be surprised if this freaking thing was used in the song (with some sound manipulation too)

my nano smoked & has a hole on the diode, still works perfectly fine, also the mini usb connector is delicate 2-3 times plugging removing the blue cable damged the connector,now connected a permanent cable to the ch340.

wow!! Amazing! You have released a project for build RAM?

Very Well done video. Thanks!!

As a stylophone collector I think I need one of these

Fantastic project!! Any news about??

Talking Stylophone?

Wäre auch sehr an einem PCB Board interessiert. Wie kann man dich kontaktieren?

for a little more you can get the most affordable Korg and Behringers. Or even a Moog Werkstatt.

I would mod this shitty thing to at least get something useable out of it. First by deleting the crappy speaker and install a jack output so it can hook up to some reverb, delay and/or chorus effects outside the machine which makes everything sound better. And then maybe tweak things and add a pot meter with a cutoff filter or something. I would never buy it in the first place. But for those who have, maybe investing 5 dollars more can do at least something about wasting the other 25 on this and make it somewhat usable.

Would you like to release the schema or gerber? Please thank you

Hi! Well done, well done! If it's not a secret, did you make printed circuit boards yourself? Could you share with me at least some information on the manufacture? thank you!

2021 yep just killed one but thanks to you its in recovery :)

Hi Ralph, du bist in der Schweiz zuhause? Ich habe Probleme mit meinem PiDP8i, wäre froh für etwas Hilfe ...

What power supply did you use for the PiDP? Was it a generic 5V supply, or one specifically rated for the Raspberry Pi?

How´s the project going? I own an original PG300, and i think it´s missing some key features. Maybe you can implement some of those in your programmer. First and foremost: the original programmer can´t switch through the patches. So you are left to using the fragile buttons of the Alpha Juno or switch via another midi controller. You can´t save a patch, either. Again, you need to use the buttons on the Alpha Juno. And you don´t want to use those at all, right? Another nice thing would be an LED over every parameter/slider/switch that is lit as soon as you alter the original (patch) value. A backup or Undo function (a temporally save in the Arduino memory) might be nice, too. And maybe a button for Chord and Portamento..? The original PG300 only has a clumsy way to switch it to another Midi channel (if your Alpha Juno is not listening to channel 1) on startup. It would be a blessing, if your programmer could remember this setting. A random patch creator is another thing i could think of... ;) In any case: great project, keep up the good work!
