**** beware... there were processors put together by hp employees from
scrap stuff at their house to play with... you will find parts from one and
all models sometimes kludged together!
used to run into this 15 -20 years ago when I would be in silicon valley
and then go out and hit some yard sales..... I imagine some of the kludges
are still floating around....

Subject: hp 21mx E on ebay (question/comment)
I looked a while ago at the HP 21MX E series on ebay.
Just now happened to
come across it again at
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2772816038&categ…
The unit says 21MX-E on the front, and also clearly says "E series
computer". However, the tag on the back says 2112A, which was an M series
machine. Odd. But further still... the keyswitch has positions operate,
standby, R, and lock. This was indicative of M series machines I thought.
True enough, M series were often upgraded to E series via a motherboard
upgrade. But the rotary key switch is obviously still connected. And from
what I've seen, M series upgraded to E they generally didn't take the time
to upgrade the front panel silkscreen.
I'm betting it's an M series. Or maybe an M that was very completely
upgraded to an E. Anyone have thoughts on this?
