WOW!!! Back pitch does not equal front pitch... Or is that a trick of the light... If so, it's wonderfully pleasing that we didn't end up down that path.

Don’t even know if its active life was in the local region or it it was transported here after decommission. Granted that knowing of an 1108/6 that was used locally could have been a probable source. Local region is Victoria, B.C., large enough for such a machine to have been around but not like a really large metro/industrial area. what The 9xxx series machines apparently actually used plated-wire memory (!), as well as being 8-bit byte based and with smaller memory modules (increments in mem capacity), so not a good fit with this module. I did look into other univac series, but in the web page I just listed the ones that seemed more likely to have a chance at being a match. part existence?

Here is the same module dated as 1967. If you trust Alamy… Could it be from a 494 or would the 30 bit width make no sense? Marc

I’m a little curious for a firmer confirmation though. 1108/6 documentation on bitsavers has been very useful, but what’s there doesn’t go deep enough into the hardware to provide a hard confirmation.
