HP 2109E cpu (21MX/E), chassis, power supply, front panel
HP 2113E cpu (21MX/E), chassis, power supply, front panel
HP 2108M cpu (21MX/M), chassis, power supply, front panel
The 2109 and 2113 are available immediately. The 2108 I will get rid of
eventually, just not sure if I'll get rid of it now or in about 6 months.
All are untested and dirty. The 2109 and 2113 will clean up nicely. The 2108
is a hard luck case and a major restoration job. The 2109 and 2113 have cpu
keys, but someone glued them in or they are stuck. The key works fine, you
just can't take the key out. The 2108 has no key. I will test and clean them
first if I get a chance. No I/O or memory cards included. Some memory and/or
I/O cards will probably be available from me at a later date.
I will also have some as yet undetermined quantity of HSFCA memory boards
available (not usable as main memory, just ECC)
Also available - HP 21MX 12979A rackmount I/O expansion unit
Items I'm looking for...
HP 12920/12921/12922 three PCA Multiplexor set
HP 2102E high speed memory controller PCA qty 2
HP 13210A disc interface PCA for spare
HP 12597A 8 bit duplex register boards qty 2
HP 12531C or D HS terminal or Buffered TTY PCA (qty 1 or 2)
HP Blank PROMS for 21MX loader roms
HP Blank PROMS for 21MX microcode roms
DSI 2400 paper tape reader/punch OR...
... RS232 interface board for Facit 4070
Data General 6030/6031 8" floppy drive
Data General Paper Tape reader, don't know the model number, for Nova and
Eclipse
Any spare Data General Nova/Eclipse boards (Nova 3, Eclipse S/130 or S/200),
primarily cpu sets, disk, cassette, memory
Data General 6045 disc drive
DEC H212 8K core memory plane for 8E

PS - Bob, now that I've been using the 21MX front panel for a while, I gotta
tell ya, I prefer using the 2100 front panel. What's this "store" button
crap? *GRIN*

The 2100 panel is total junk! Try a 2114 my friend, there is nothing
that compares with HP's touch
sensitive incandescent backlit sensors, and the hacked relay used to
make the 'click' as if there was
a mechanical component to the capacitive switch.
But for appearance, the 2116 rules.
Remember 21MX's use boot roms, the front panel is very rarely used. It
was also HP's last front panel.

You're comparing a 2100 panel to a 2114/2116. I agree with you there. I was
comparing the usability of the 2100 panel vs. the 21MX panel. I hate having
to hit "store" each time. On the 21MX, you have to hit store when changing a
register value. On the 2100, just select a different register, or hit INC M,
or hit run, and the modifications are automatically stored. To get the old
contents back, just press the register key again. Makes things much easier
for one who works on the front panel a lot.
And the front panel is used a LOT for a lot of HP diagnostics, regardless of
loader roms being present or not. Just my own personal opinion :)

I do agree, the 21MX front panel is a little harder to use.
But the 2100 is simply not HP's best effort in this area.
For usability, the 2114 rules, for appearance, the 2116 should win, but
it gets major points
off for lacking a displayed Switch Register, a flaw fixed on the 2100.
The 21MX front panel does not need toe Store button to be used once its
in the Run mode, so
the diagnostics should act exactly as they do on the 2100. The only
time the 'extra' step is
needed for the 21MX's is during the bootstrap process, or when you have
no boot device
whatsoever.
Its a very forgivable fault in practical use.
