I'm surprised... well, not that much, I have
lurked on this list for a
while now.
When I first read this article and saw how many responses it got I
thought that now I would finally learn some more about my old DP2200.
But the discussion immediately changed into a discussion about various
chip carriers.
In a vane attempt to steer the discussion back into the original topic,
the Datapoint 2200, I wonder if there is anyone else that is restoring
these machines and if there are any schematics out there.
I added a small teaser with some pictures of a 4 kbyte memory card, the
only thing I have of it in my apartment.

Neat!
I had a Datapoint 2200 for a while. It didn't work either. I see yours
is a first generation (bit serial). Mine was the 2nd generation CPU
which was still discreet TTL, but was data parallel.
Eventually I sold my 2200 due to (1) lack of time and (2) lack of any
documents. I had contacted a couple people who had schematics and such,
but neither was willing to make copies or loan their docs to me so I
could copy them.
I even went to a reunion of datapoint employees and found one guy who
had just about all datapoint internal engineering documents and change
notices in his barn. However, 6 months prior he moved to a smaller
place, so he incinerated everything!
The person I sold my machine to, David Monroe, was one of the engineers
who originally designed the machine. He has schematics too. I never
found out if he got it working again.
