EPROM signature, where to get ID list?

Or at least can anyone identify my eprom, Manufacturer 97h, Device 32h?

Manufacturer ID 97h could be Texas Instruments, at least 97h/04h is their TMS27C256, 97h/85h is the 27C512. You see, there is no logic behind the device ID - perhaps you can provide more information about the package size and expected capacity. Or read what's written on it?

Copied from the list of devices supported by the TopMax programmer:

Manufacturer:TEXAS-INSTRUMENTS, Device Name:TMS27C020 Num. of pins:32, Chip size:40000h(262144), Word size:8, Mfg. code:0097, Dev. code:0032, Prog. algo.:Snap, Vcc pin:32, Gnd pin:16, Vpp pin: 1, Prog. Vccp: 6.50V, Prog. Vpp: 13.0V, Pulse width: 100Us, Over prog. pulse: 100us

Excellent! Thank you Piotr :-) I found version 2.8S of the software for that programmer but it doesn't have a search facility, only select a device from the list but it confirmed your info. Would it be possible for you to email me that list of devices supported because I have now found =another= eprom 87h/32h and I'm wondering what I will yet uncover. If possible, send it here

TIA, GP.

I'm sorry, I wasn't precise enough, because I don't have this list as a plain text, either. However, in case of your previous request, you can do a binary search of the TM.DAT file for the sequence of bytes:

Unfortunately the search for 00h 87h 00h 32h didn't yield any hit, except that 87h seem to stand for the Manufacturer Code: INTEL.
