I'm hoping someone on the list can help. I rescued an IMSAI 8080, as well
as a large (and heavy) dual 8" drive chasis (fully enclosed).
The IMSAI is stocked full of cards which I haven't figured out what they
are yet as they're in pretty tight and I'm afraid of breaking something
yanking them out. I'm assuming at least one of them is a terminal
interface card and another an interface for the drives.
Here's the two problems with the unit though:
1) It appears to be missing the main processor card. Everything else
looks mint, including the control panel and the ribbon from the pannel
to the control/processor card is intact as well.
Hi
It sounds like it is missing the processor card. Still, it may
have one but it doesn't interface with the front panel. The only
signals that run through the ribbon are data signals. All of
the rest go through the bus. This means that if you don't need
the ability to used that readouts of the panel, you can do
things like reset and run without the ribbon. Check to see
if there is some other processor card there.
I see original 8080 cards on ebay often but there were many
second source Z80 cards with the ribbon cable connector made
as well. I see these very often on ebay. Just keep an eye out.
2) The people (the university janitorial staff) that were throwing it out,
cut off the power cord. Hence there is a stub of a cord connected to the
power supply now running out the back.
So, install a new cord.
I'm basicly looking for any help/suggestions in how to indentify the cards
and what I can do to fix the other two problems. Thanks!
Take pictures. Put them on a web page. Note any text found on boards.
