I opened my NEC PC-8508A ROM/RAM Cartridge today. It was, of course, just
like your's pictured below but my ROM sockets (4) were white. So clearly the
NEC PC-8500 was designed to employ option ROMs. Still not sure if any were
made or if the Real Estate and Expert I & II program advertised were ROM-based.

From your pic, there are ROM sockets in the PC-8508A! I wondered if they
offered any ROMs? Never came across any.

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.
