I recently had a problem with the ROM of an old equipment.
So I felt the need for a backup.
I read the ROM file that was in my equipment. you can download it.
Be careful. maybe it's not compatible with your equipment.
My equipment is R2008C HS, support Cellular model.
A6 Audio Synthesizer.
This EEP soldered on board (25 VPP, but GENERAL 2716 compatible may be.. )
It seems to be just a sin-wave data table.
MM2716
A8 IEEE interface, General 2764 ROM.
1st AM2764
2st TMS2764
A9 Processor Board ROM 1, 2, 3 (U6, 7, 8) MCM 68764 (25 VPP, it's not general 2764 compatiable.)
I was able to read it with HILO ALL-07.
New programmers(ALL-11 etc) probably won't support it.
Good luck. DS1ORJ
