Well, I haven't actually modded it since I got it working as a 128k DRAM board, someone.
I was working fine for a few days and it's stopped since. Everything since then has been me trying to get it back on its feet. I'll try the BN54 ROM as soon as I can get a reliable ROM burner. (I think I will have to bite the bullet and see if I can find something a bit more old fashioned that supports the older ROMs I use.)
BTW I checked and I did try programming this with the BN56 EPROM and it didn't work. This isn't a premium baseboard. Anyone know which file in the Repository is the "proper" BN54 ROM? There's 3 different candidates in there :-)
Cheers!

Ps. Tests and fixes will be slow this week. I'm work from home which means my entire workbench is set up with my WFH setup instead of all my test gear. OTOH, work from home is so nice!
