I have a Z80 computer that I built from a kit in 1978 and I hate to just
set it on the curb and scrap it. It was designed and sold by 'the digital
group' of Denver, CO. It has a Z80 8 bit microprocessor, 2.5 mh, 64K
memory, 80 X 24 output to a monitor, dual 8" floppy drives added later from
Bell Controls of CA and a CPM operating system.
Components:
1 Cabinet containing processor board, memory boards, disk I/O boards, TV
output board and power supply.
2 Keyboard
3 Dual 8" floppy disk drive
4 19" monitor for output
5 Modem
6 Documentation
I would like to donate it. Interested?

My best friend in high school built one of those - it was really cool.
His had "phi-deck" high-speed cassette tape drives - it always looked
so busy and efficient whirring the tapes back and forth and loading
and unloading the heads. I built an IMSAI 8080 at the same time. I'd
love to have a digital group system to go with it. I'd give yours a
good home with my IMSAI and my Heathkit H-89. What do you say? If
there's a lot of interest, maybe you should hold an auction...

Haggle Online (www.haggle.com) has a "private auction" category that lets
you create an auction that doesn't get listed in any of the public
categories so you can duke it out among yourselves if you list it there
(and it's free).
Speaking of IMSAI's, I just bought a PROM/RAM board from somebody (it's on
its way) without knowing exactly what it is (that's my standard MO). All
I know is that it's a Vector Graphics board for an IMSAI (and comes with
the original receipt from IMS, as well as an original IMSAI catalog!) and
I can tell from Bill R's Tandy catalog
(http://incolor.inetnebr.com/bill_r/Tandy_TOC_Frames_Page.htm)
that it was intended as a front-panel replacement (are your fingers red
and swolen?).
My guess is that a PROM/RAM board is sort of a ROM emulator. Am I close,
or is it just a board that can handle PROMs and RAMs?
