Hi All!
Looking for help getting programmed ROMs to Maryland. This is to support an exciting real use case for a very vintage machine.
Needed: someone with a ROM burner and two 27C256 chips (28 pin DIP) in the USA prepared to write out a ROM image and post onwards.
Image is 64KB ROM and needs to be interleaved onto the two chips. I can split binary for writing out manually if needed.
Please PM if you can help and for further details.
Thank you very much indeed. Note: machine datasheet specifies PD27C256AD-15, I think these are standard 28-pin 150ns parts.
