I ran a batch of MOS 6540 adapter PCBs, and I have
created a small FLASH
replacement for the 2364 and 23128/23256 DIP ROMs. Some of those might be of
use on other 80's era machines.
I think that those would be quite valuable, especially if you decide to
create variants that allow a similar drop-in replacement for older EPROM
parts.
