Crowd fund me ? Gimix Ghost

I would love to get a schematic of the video card but I was seriously outbid by 2 bidders on Ebay. Docs went for over $100.

Amazing system.

Well you know it kinda works from the eBay pictures, so no need to reform the caps.
It’s probably a good idea to reseat all the cards.

Will it start up with monitor prompt or try to boot from a disk ? Exciting isn’t it!

Yes this is very cool!

I'll start without the disk drives. I'm hoping that I can boot to the ROM monitor (GMXBUG) and then dump the ROMS. I don't think there are many ROMS that work with the video card out there. I'll then play around with the boards and see what works. I have a Peripheral Technology SS30-IDE board. I can S1dump an IDE boot routine and see if I can get Flex running (obviously a bit more complex than that but ...). I need to rebuild my Fuzix 6800 C Cross Compiler (under Linux) so I can then fool around with the sound board. I have DeRamp's Python to Asm/Hex code so I can generate sounds with the sound card. I intend to work with the Pico W boards and add that to the mix. Maybe get Fujinet running in Flex.

I just got done with VCF East, I run the Learn to Solder on that weekend in the Computer Deconstruction Lab (CDL), my makerspace.

is the sound board a "Newtech Model 68" or something else ?

 

[ncherry]

It's a Newtech Model 68

It's a Newtech Model 68

I see you already found my GitHub with code for the corsham technologies clone of the newtech 68. I got it to play “the entertainer” but a lot of the code is a work in progress. I got distracted..

I also grabbed:

GitHub - robin7g/swtpc-sound-card: M6800 assembly language and some python code to make SWPTC play wave data!

M6800 assembly language and some python code to make SWPTC play wave data! - robin7g/swtpc-sound-card

github.com

and I thought I found some python code to convert sound files to asm. Saw a Youtube video that had it play the sound file for the War Games "... play a game"

I'll need to see where that is. Thought I added it to my notes. Oh it's the SWTPC M68 DAC Wave Convertor.ipynb file on Robin's Github link.

looks like you can get a model 68 copy here :
retrospy model 68 model 68 music board

if anybody wants a bare PCB for the Corsham Technologies rev. 2 board I still have 4 boards from my PCB way run. If you are in the USA just PM me with your address.
