ROM/RAM boards, but the 2001 boards have unusual chip sockets. They have extended sides so the make contact with the pins all the way up side. This means the usual turned pin headers I use on the ROM/RAM board do not fit very well.
pet microSD disk drive to load it, I need BASIC 2 or BASIC 4. But first I will need to fix the IEEE-488 port, as that doesn't appear to be working.
