27C256 ROM Burning Request: Shipping to Maryland

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.
 
I have had excellent results dealing with hobby roms.com. Stefan has been able to program 2716s for my S-100 systems, as well as a 27128 for my TRS-80 Color Computer. You send him the HEX file and whatever instructions about what you need, and he sends you back the EPROMs.

Easy-peasy!

Good luck!
