Is a Gerber file available for your DIP32 ROM card?

Is there any DIP-32 EEPROM less than 512kbit (64kB)?
It requires more complex address decoding or it will just waste address space and possibly overlap with the existing OPTROMs.
So it requires to change the schematic completely not just re-route the gerbers.

Sure seems like most DIP32 eeprom devices that are Dip32 are larger than 64KB

The poster I was replying to had a Dip32 “Disk on chip” adapter, so these are larger than 64KB devices. I’d like to make one with diagnostic tools on it.

Hi Douglas-o, I'm still working on this. I'm thinking about creating a repository to upload the gerbers, but the menu.exe is already available at

I'm also working on Mega_bios 8in1 rom.bios for IBM pc xt and clones

Well this won't work for the PLOP boot manager I was hoping to use its a 64KB image so I'd need a 27c512 chip. Guess At Least I'll have something I can put xtide on.

plop is a PCI option rom. Not an ISA option rom. The two are very different. You'd need a PCI NIC with EEPROM socket for plop.
