[sdiy] Board View Software - could we make a database of this for vintage synths?

[thx1138 at earthlink.net]

Hi Peter,

As the Oberheim, Sequential Circuits and Oberheim were Z-80 based, we programmed the code in assembly. At PPG, we used Motorola 6809 and used the Flex OS for the 6809 and some assembly code too.

Basic would not have worked back in those times as memory limits , performance etc.

My eprom programmer is my E-Mu Audity CPU board, we only built one Audity Synth system, which is also Z-80 based. The OS on the Z-80 system is using the RIO OS for the ZDS-125 Zilog dev. system we hacked. The Emulator 1 and Emulater 2 were also using this OS.

Mind you that this computer has Dual 8” floppy drives. I have not powered it up in over 15 years. Not sure if it will boot or not. It was working when I put it into the closet.

It will also run C/PM OS and we used them at E-mu for our accounting and word processing computers. I believe I built about 6 systems for Marketing and Engineering.

Does any of this old info help?

best regards,

Terry

By the way: Thanks Terry, you seem to be someone I'd really like to talk to for a while. I'm based in germany, so that might be a long therm wish........ but you'll never know. As an electronics student and former electronic musician, it's my goal to build my very own synthesizer, with everything done on my own... That is the plan I have in mind, so learning synthesizer theory and examining construction of already buildet instruments (and the thoughts and solutions of them) is my dirty hobby right now. So if we could share some thoughts I would be very much appreciated. For this I am of course also very interested in data for ic's, in plans of instruments and good literature about that topic.
