Subject: [N8VEM: 19848] Altair 8800 Motherboard Replacement
To: ***@googlegroups.com
Hi Guys,
I have an Altair 8800 full of cards, but the backplane is in 3 4-slot
sections wired together.
Does N8VEM have any motherboards that will fit my Altair should I choose to
restore it? It has not been powered up since before I bought it way back
in the late â70s to early â80s timeframe. I looked to see if I could
easily disconnect everything from the power supply several years back and I
found that the front panel is permanently wired to the backplane so if I do
replace the backplane I have a lot of work ahead of me. Total restoration
could take a while and my workbench is kind of dinky so leaving everything
laid out is not an option at this point. I know there is at least a 21
slot S-100 backplane, but from what I remember looking inside my Altair, I
wouldnât think that would fit.
What procedures should I follow should I decide to dive into this project?
I would like to see it run someday though I imagine it would be painfully
slow compared to my 25MHZ Z80 Multicomp running MP/M with 512KB of ram.
Any thoughts, ideas, helpful hints?
