IBM 1401 Data Center model on eBay - test-drb@ccmp.vtda.org

13 Jan 2011

Regarding the charming wood/metal scale model of a "1401 Data Center" on eBay,
in addition to the 3 1401 Central Processing Units, many of the models are actually
for an IBM 7070:  main frame cabinets, console (7150), and card reader (7500).

As a 1401 system, two of the 1401 CPUs are missing their mainspring!  ;-)
The IBM 1402, in addition to reading and punching cards,
also delivers AC and DC power to the 1401 CPU, 1403 printer,
and 729 tape string.  Technically, the model system is missing two 1402s.

Any large 1401 system would also likely have 1406 extended memory units
(12,000 characters).  I suspect many 7070s also had RAMAC/disk
storage units (7300), as did some 1401 systems (1405, 20 MB).

For info and pictures about our two operational tape-based 1401 systems at the 
Computer History Museum(CHM), restored by a grand team of retired IBM CE's,

p.s.  The CHM just opened to the public its new marvelous Revolution exhibit!

p.p.s.  For mounting SMS logic boards, the 7000-series main frame cabinets used large
"Rolygon" sliding gates, while the 1401 used smaller pivoting gate
"Cube" packaging.

  Okay, somebody needs to pick that up, either Al
for the CHM or Sellam 
 or Evan....  put that on display, that is just too damned cool !!!
   There have been links for sales of sets like this mentioned on the list 
 previously but I think they were folded cardboard, not the detailed 
 wood and metal of this set.

 The ebay page linked to this:

 Great story, Bob. (.. now we know who to blame)

 And speaking therein of 360 front panels:

 Awesome - I saw a set like this many years ago (let's say mid-90s) in
 the window of an "antiques" (junk) store in St. Charles, IL.  I think
 they wanted around $250 for it, and those were the days I was scraping
 together $5 for meals, so it wasn't going to happen for me.  I always
 assumed it was a salesman's kit, for helping to lay our datacenters
 (maybe it came with a big sheet of scaled grid paper to represent
 floor tiles?)

 Well, I'll be bidding...
