   The Metrodata was a weird system.  It looked like a simple text
processor, but you had to log into the proper 'page' to edit the text
for each of the six video cards.  Some cards had three pages, like the
leased line AP news feed.  You had 'Page Title" 'Body' and 'Bottom'.

   The cheap bastard who ran that CATV system was too cheap to spend $8
each for new 8" floppies.  He put it off for a couple months, till both
the main disk drive lost the heads when they welded to the worn media,
but the backup disk in the secondary drive had crashed.  I spent almost
a week piecing the system configuration back together from almost 100
bad disks.  The home office 'suggested' that the PM schedule I insisted
on be met every month, if the manager wanted to keep his job.


   I am not surprised that a 6800 family computer is still working.  I
think i still have a couple Tandy/RS Color Computers around.  I had a
pair of ISA cards for the XT that let you run Apple II software from an
Apple disk drive.

   Some of the last embedded systems I worked on used the MC68340, and I
hated the early production with the PGA package.  The SMD version was a
ot easier to troubleshoot, and modify for special products.  BTW, one of
those boards is part of the KU band communication systems aboard the
ISS.

   The other embedded controller used a Cyrix 586 PC104 based
motherboard, and a dozen small Motorola MPUs. It had a 40 MB solid state
hard drive, and 32 MB of DIMM RAM to run the Telemetry system under
Windows CE.
