I will be letting the MESS folks know about the documentation and rom dumps
once I have the work finished. I just found a service manual for the 8562
and will be adding that information to the scans on bitsavers.
The hardware for the 856x is a lot like the Terak in that the I/O is
incompatible with DECs, and there aren't any driver sources around.
So right now it's just getting as much information collected as I can find
so that someone might have a chance of doing something in the future.
Considering how many Tek development systems and Teraks were sold, I'm
surprised at how long it's taken me to get this far. I was looking at some
of my old emails and I have been working on tracking this stuff down for
almost 10 years.
It did turn out that getting those two 8560s in May was pretty important
for both of the projects. I discovered that there were Terak floppies mixed
in, and that the seller had a Terak monitor and keyboard. He had sold the
CPU sepratately :-(
I've not actually been able to get the 8560s to work, but it did prompt me
to dig out the 8550 and a pair of 8562s that I had in storage and was able
to prod one of them into running after I had the 8560 service manual and
Tnix documentation that came as part of the eBay lot.
