History:
The inventory of SMS cards from Arnold Schweinsberg, taken Nov 17th and Dec 1st by Milt Thomas, Bob Erickson and Glenn Lea. The SMS cards were stored in failing shoe boxes, and were moved to larger acid-free museum flat boxes, and marked with the source shoe box number. "Key punching" and "data processing" by Ed Thelen ;-))
It looks like we have 116 different types of SMS cards as spares.

Current status: as of Wednesday evening May 17, 2006
In May, 2006, Grant Saviers brought in a large 6 drawer cabinet, the bottom four of the large drawers are suitable for storing SMS cards. The contents of the museum boxes are being sorted into newly labeled dividers in the new drawers. SMS cards donated to the 1401 Restoration Project from other sources are also in the drawers and included in this inventory. As the shipment from Germany had no spare 1403 hammer driver modules, the 12 AEC types below are from the Visible Storage 1401.
There are "excessive" numbers of some types of spares - such as do we really need 53 spare 4JMX cards in active storage? So a system of Overflow Storage boxes are being used to contain the "surplus" SMS cards.
Comments by Grant, Tue May 16, 2006: Updated to "..." as items performed
There were a few (5?) cards that had been "type changed" with jumpers or were reconstitued from scrap (epoxied on gold fingers) or marked in pen with a new type and I did not not put them into the drawers. ... Here are my suggestions for what next: 1. ... Devise some sort of paper logging of the spares usage. 2. Identify what cards we really have no spares for, in all parts of the system. 3. Contact other 1401 owners to see if we could swap spare cards, where we have way too many of one type they have a need and vica versa. Get this approved by the Museum staff first. And/or borrow spares from the VS. 1401, drives, etc.Comments on this inventory taken Wednesday May 17, 2006
- An orange dot on the label in the drawer indicates that overflow is located in boxes
- Chuck Kantmann counter, Ed Thelen recorder, Ron Williams "customer checker"
- Boards in the repair cycle are now all in one box. Not counted in this inventory
- Some repaired? modules in drawers in baggies
- This inventory includes card types observed in the 1401 - a reason for some of the zeros
- We have not examined the card types in the 729 tape drives, some known to be not listed
