This is the first time I've been to an electronics flea market, so I
don't know how it was, but I was disappointed. I came late, and about
1/2 the stuff was oscilloscopes, another 1/4 was Mac CPUs, and an
8th was PC network cards. Everything was priced at or above market
value (almost). I will still go next time, though.
There were a bunch of "IBM RT" units. These were enormous PS/2 like
things. What were they?
I could have gotten a Zenith XT laptop for $10, but I opted for a
free Data General One being used as a wheelchock. It's in good
condition, but the LCD is smashed. I think I will hang it on the wall.
Does anyone have any ideas what I should do with the rest of the
machine? Does anyone have replacement LCDs?
PS. I would have gotten a shrinkwrapped copy of MacOS 6.0.7 and A/UX,
but the guy changed his mind about selling it.

RTs are EAPC RISC (6.0 MHz) based machines that have 68881 FPUs. Their
greatest moment was when they were used as nodal switching stations
on the NSFnet backbone.
They run either AIX or AOS (the latter is 4.3 BSD and comparatively
rare).
Usually you find them with around 12 MB RAM, a 70 MB ESDI disk
and controller, either a token-ring card or an Ungermann-Bass
ethernet card. And, a display adaptor, if you're lucky. :)
IMHO, not worth picking up unless free. They are very common,
extremely heavy for their size, and either OS has serious problems.
There is a FAQ still around (comp.sys.ibm.pc.rt).

Did you notice the numnut selling those SGI IRIS's for $400?
He also had an 11/23 he wanted to sell for $100 and _wouldn't_
budge. He told me they were 'classic' computers and could
fetch even more in the collector market... JEESH! There were
some pretty good deals on scopes, so I'm not complaining about
the abundance of test hardware. Several Apple II's... I
walked away with an original Atari joystick for $1, a set of
Atari 800 programming manuals for $5, and a coco2 with drives
for $2... those are the kind of deals I'm looking for. ;-)

PS - I would have paid up to ~$20 for the 11/23, but $100?????
