I found an old add that said and option were programs called Insurance Expert
I and II and Real Estate Expert. Not sure if they were ROMS.
Interesting.

The rumor I had heard way, way back in the day was that NEC had originally
intended to release ROMware for those cartridges. Not sure it ever happened.
I'd like to believe they'd at least released the technical information on how
those ROM sockets are mapped within memory. We just need to find technical
reference manuals covering the PC-8401A, 8500, and/or 8508A. (Yeah, I know,
I'm laughing out loud as well...)

I've never got it into all-RAM mode. Admittedly though I haven't tried that
hard. I thought the point of that was to run CP/M, but the only way I know you
can do that is with the floppy disk attached, that no one has. Theoretically
you could probably do it with just the ROM/RAM cartridge. If someone has docs
or files that would help.
I do believe I have the boot disk though.
The NEC PC-8508A ROM/RAM Cartridge...is there a "ROM" socket in there?
I don't know. I will open it up.
