3/7/2015: Yet another long period where I've been consumed with work & museum parts just continue to pile up. However, some changes have been made. More explanatory text added and a new device, the AMF 662/D Computer.

9/11/2014: Another long period where I've been consumed with work & museum parts just continue to pile up. However, a new WWII Mark 6 fire control computer has arrived & I love old mechanical computers so much that I updated the museum pages.

3/30/2014: An IBM System/32 has been added. This system is special to me since I worked on its design from 1971-1974. Accordingly, I have given it a "top-level" category in the museum.

8/30/2013: An IBM System/3 Model 6 has been added. This system is special to me since (1) My first management job in IBM (1969) was developing BASIC software for the Model 6, and (2) I met my wife (then, an IBM programmer) while working on this product. Accordingly, I have given it a "top-level" category in the museum.

3/15/2013: Another major addition added to the old military section: another (yes, I already have one) Sperry S-1 Bombsight. This new one has several features the earlier one didn't: the M-2 enhancement, made by IBM, a manual, a logbook showing its provenance, and the original transport case.

1/10/2013: A major addition added to the old military section: a very rare Sperry P-4 (Gunsight) Computer. Also, a new analog computer was added (but with no information, just pictures).

12/19/2012: Some new IBM control panels added to the IBM 705 section. There are some items here that I can't fully identify; please let me know if you recognize them.

12/15/2012: Two important new items added. First is a rare drum storage unit from behind the Iron Curtain. Second is a rare IBM/RAND JOSS console, from one of the first time-sharing systems in the early 1960's.

12/12/2012: Some more IBM plugboards including my favorite, the IBM 407.

12/10/2012: Shame! If you notice below, it has been exactly one year since I updated the site; I was very busy this year. My New Year's resolution is to do much better this year since I have hundreds of items that need to go on the site. I'm in the process of changing the structure of the large "old military" category. As a gesture of good intentions, I've added another rare optical bombsight from the 1950's.

12/10/2011: Added a new type of IBM read-only storage: Balanced Capacitor ROS as used on the System/360 Mod 50. Added a new Farrand sighting mechanism (pictures only for now, text to come soon). It is not clear (to me) whether this is part of a bombsight or a navigation computer. Added the sighting head to the A-4 "Gun Bomb Rocket" Sight (the computing component was already in the museum).

11/27/2011: Added a great new device: a Fairchild A-4 Line-of-Position Computer. Also updated the name and text for the Bendix MG-1 Central Air Data Computer.

11/16/2011: Did some cleanup in Old Military section; it now has an index to its contents. Added some text and more pictures to one of our most interesting and rare devices, the B-36 A-1A Bomb Release Computer. Added an APA-16 Radar Bombsight Controller. Also added a new IBM control panel. Added an IBM model 10 keypunch and some modern IBM control panels.

11/1/2011: Added several miscellaneous items that were collecting dust in the back room. In some cases I've just added the pictures; the text will come later.

A particularly nice item is a massive control panel from a Honeywell Multics mainframe.

Another very interesting item is a tester for the Titan IV ICBM (serial number 1!).

The tester for the B-29 Central Station Fire Control computer was added to that section.

(Also, updated the K3 gunsight section showing our multiple devices.)

6/1/2011: Added miscellaneous old military stuff that was laying around. We now have the sighting head for our T1A bombsight. We've added some components from a M1 Toss Bomb Computer. Also, a Mk23 Bombsight sighting component. Also, the controller for an AN/ASA-24 Navigation Computer. Also, a subassembly from an AN/MSQ-1 Radar Tracking Subassembly. Also, a Variable Gunsight Head controller. Also, a Mk18 Gunsight along with several accessories.

4/11/2011: Some new IBM items added: Some System/360 control storage components with lots of text, and a System/360 Model 30 console with no text yet (some coming soon). Also a new CSI Analog Computer added with no text yet.

3/27/2011: Some new IBM items added: A cool IBM Magnetostrictive (wire) Memory and more card equipment plugboards (as well as more text about our card equipment).

11/2/2010: Over last 2 weeks I've done cleanup on the site (spelling, typos, missing pics, etc.) as well as dumped a lot of pics into "incoming" categories under components, and ibm. A couple of items got text, but most of these new items are just pics for now. One new item is a Sperry A-5 autopilot control panel (under the S-1 Bombsight).

10/19/2010: A new Sperry T-1A Bombsight unit has been acquired to go with the previous unit. While similar, there are some minor differences betwenn the two.

10/18/2010: A complete Sperry S-1 Bombsight (World War II) has been acquired to go with the previous disassembled S-1.

10/15/2010: A major new encryption item added: a Russian Fialka encryption machine.

10/07/2010: New pictures added to various categories (there are hundreds of museum items not yet shown & I'm gradually going to add pictures first, then text), and a major new item added, an IBM 705 Console.

9/28/2010: Minor editing and two new pictures in B61 Preflight Controller.

8/11/2010: Two new components added in old military: B-1 Bombsight Stabilizer and B-29 Pedestal Gunsight.

8/05/2010: Minor IBM editing & pictures for some IBM plugboards.

8/04/2010: New placeholder entry created for IBM 3420 tape Drive.

8/03/2010: New entry created for 3-D Gyro Navigation Device.

8/03/2010: IBM category updated for (1) new pictures of 9020 console and (2) placeholder entries for some more IBM equipment: one picture, no text (yet).

7/28/2010: New Old Military entry created for A-4 gun-bonb-rocket sight, minor edits to this done all week long.

7/26/2010: New top-level topic created for B61 Preflight Controller, edits to this done all week long.

7/26/2010: After a year of ad hoc & desultory updating, I'm trying to get organized; so I'm starting this change log.
