I am about ready to start balling after reading this!
About a month ago, I was cleaning house and sent all of
the bubble memory stuff I had to the recycling center. I
had an ISA based development board and several bubble
memory modules.
I had plans of playing around with it, but after 10 years
of the stuff sitting in my closet, I felt it I would never
get to it, plus I didn't have any docs and it's condition
was unknown.
The board and modules were from my former employer who
used them for a memory module that went into a flight
navigation device. I have written about this in the past.
The navigation system had a 6809, with 3 each 6850 and
6852 for three chanels each of RS422 ARINC communications.
It also had a 6822 PIA. Basically it was a CoCo in
flight.
I believe I still have the Intel Manual and if I find it,
I will post it to the list or send it to someone who can
scan it and put it up on the net.
It never fails, as soon as I do some cleaning something
like this pops up. Now before I toss this, is anyone
interested in a ISA to PCMCIA card? What about the
ISA/EISA book that I posted to the list a few days ago?
