Hi everybody,

Has anybody managed to emulate the Alphatronic PC yet?
I can find very little information on the net about this machine, let alone the ROMs or an emulator.
I have the BASIC ROMs here - what I should do with them? There's no way to save binary from BASIC so I copied it to a massive REM statement, saved it out, read the cassette file, and grabbed the ROM from there. I now have 3x8KB ROMs.
Of course the T/A doesn't use it's BASIC from ROM, it copies it to RAM first, so I'd guess there may be another bootstrap ROM inside it which does the copying, but I've not looked into it properly yet.
I also have the manual scanned in if anybody's interested...!

Let me know where to send the BASIC ROMs though and I'll get them sent there!

May you can contact Micko to send the T/A Alphatronic PC stuff? He is the MESS coordinator.

Perhaps you can try to save the highest 8KB of the RAM in a similar matter?
Maybe there is still some leftover code in there which took care of switching out the actual ROMs that may help in locating the remaining 8KB of rom (if old-computers.com is right..)

Also, are you able to create readable pictures of the pcb and keyboard (top and bottom)? That will make emulating it a lot easier.

I've put the ROMs here:

They're not going to be there forever though as they're technically still copyright. However I think it's important that the emulator authors have a copy.
As for the manual, once I've made it easier I'll put it somewhere too.

You might want to update. smile

I opened up the Alphatronic today, and lo and behold there's the 32K ROM which holds the 24K BASIC... and there's also two other EPROMs, one of which looks like the character ROM (a 2732) and one which I presume is the bootstrap (a 2764).
One quick visit to my trusty Amiga 500's EPROM burner later, and I have both dumped.

For those who are interested, here are some pics of the motherboard:

Excellent... this will provide a good start to emulation. smile
