Many thanks for your pointers on this. The information let me identify 6 out of the 72 SLTs I currently have. Looking more closely at the boards I have, it would appear from some of the date codes that it was made in 1970.
SLT codes I have are (module number, quantity, function): 361431 4 361440 6 361441 1 361442 2 361443 6 361444 13 361452 19 361453 1 And-Or-Invert Medium Speed 361458 5 2 Transistors, Medium Speed 2391665 3 2395140 12 Any more ideas how I could track these down? Author of the original SLT document was D.C. Brugnolotti - I wonder if he reads here? Alternative plan would be to locate some modules which *were* listed in the documents - any idea of a source of supply (looking further on Ebay, but a Plan B would be good!)? >Sounds like a fun project -- let me know what comes of it. You >should exhibit it at the Vintage Computer Festival! I'd love to. I live in Japan, but visited the Computer History Museum last time I was in SF and had a very interesting afternoon. VCF would be a good excuse to go back there! I'm thinking of building a SLT powered Nixie clock if I can get enough And-Or-Invert SLTs to do it (need about 100). Thanks. Colin.
