Need help with Technical Specifications[edit]

I started the article and added data I was able to collect from various (referenced) sources. However, data does not seem entirely consistent (I may be wrong)

Manufacturer lists 1960 as the year of production, but other sites mention end of 1950s (probably design) and even 1961 (probably release).
Memory is stated to be 4096 of 30-bit words. There are few potential problems with this piece of information:
- This is unusally long word for that time
- That amounts to 122,880 bits total. Assuming that vacuum tubes were used for memory (there aren't enough transistors) that would mean more than 72 bits (e.g. 128?) per single tube. Was this density possible ever?
- If memory susbsytem is not accounted for with 1700 tubes and 1300 transistors, then what was it?

Can anyone help dig out this information?

One more thing. I originally found and thought that CER-10 was entirely based on vacuum tubes and was ready to accept that it also used relays and other technology (e.g. for memory) but not really transistors - seems kind of too early.

Can anyone check?

Memory was of magnetic core type and it indeed did use Germanium transistors. Found that. The rest is still open.
