Much cheaper than the other one, and even includes an evilnet adapter.

Not affiliated, other than drooled over the auction. Now, were are the
wipes for my flat panel...

I'd love to buy something like this for the OS/2 museum but the 
shipping is usually a killer.  Looking at this auction, it would run 
about $31 - 40 to ship to PA.  And that is actually cheaper then a lot
of these I have looked at.  I may bid on it and see how it goes but 
most likely it will cost too much for my projects limited funds.  :-(

Hi!

> Much cheaper than the other one, and even includes an evilnet adapter.

A very nice machine no doubt, but the other one is a 25MHz boxen and
somewhat rarer. 20MHz short planar Model 70s seem to be the most common of
all the Model 70 systems.

I've seen references to a 20MHz "long" planar in IBM documentation, but
never in an actual Model 70. Has anyone seen such a beast?

The long planar "lived" only about 1 year. It was that designed for the 
same fully robotized assembly line the Mod. 50 (non-Z) dropped off.
The short planar and that of the 50Z required some person (or a more 
complex robot arm) to attach the speaker / battery cable, which was not 
existing on the long-70 / 50-021 systems.

After these machines IBM dropped the cable-less fully robotized 
approach. Too much monkey business. The next generation (Mod. 55SX and 
the 56 / 57) then had cables again.

Last unit still in production on the original 1987 machinery (after my 
infos) is the 4207 IBM Proprinter-III in some small factory in italy 
made for banking printers.

The first generation 16 and 20 MHz Mod. 70's use a long board.
It is shown in the HMM planar section. They label it "Reduced" and 
"Full" size.
The long board suffered various illnesses. Required the DASDDRVR.SYS 
under DOS 3.3 - 5.0, lost date / time occasionally for no reason, 
disliked various types of memory modules (single sided 10-chip / 8 data, 
2 (!) for parity) that ran on short boards with no problems. The path 
between CPU and memory section was about 3 times longer than on the 
short board, which might explain some problems.

Sometimes problems with 8514/A and e.g. Token Ring (long 4 MBit) and / 
or 3278 long card showed up in the way that one or neither worked properly.

I - for one - was glad when the short board arrived and all the problems 
were cured. If you have about 200 - 300 Mod. 70 around at the customers 
you learn to appreciate the fixes done at IBM back then.
