      That's entirely your call. It depends on if you want to keep the system original to how it was when you obtained it. Since the board was offered as a kit, I wouldn't consider populating the ROM option really a modification...at least not any more than rejumpering cards one has received with different settings.

      If you don't want to populate the ROM option and you are only interested in having a ROM monitor just to get some diagnostics done and some disks copied, I'm sure one of us has a ROM board you could borrow or buy.

      I can burn them with my IMSAI, if no one else can and you decide you want to use the ROM option on the CPU board. Otherwise, if you want a ROM board for debug and you're not concerned about it being absolutely correct for the system, I'd recommend finding something that takes 2716 EPROMs or newer. You'll have far less trouble finding blanks and, if the board is new enough, you can use EEPROM replacement devices.
