So EK-0KL20-IN-001 ("KL10-Based DECSystem-20 Installation Manual") gives, in Section 10.2 "KL10-PV Upgrade Procedure for KL10-C" gives instructions which clearly include the replacement of the main CPU backplane. However other documents make it sound like the Model B supports multiple sections. So now I'm completely confused as to the whole multi-section thing; I thought it came in with the Model E (AKA KA10-PV), and needed a different CPU backplane, but maybe not? Is the KL10-E different physically from the Model B, or not? [[User:Jnc|Jnc]] ([[User talk:Jnc|talk]]) 01:05, 7 July 2019 (CEST)

MC at LCM

I thought MC went to Sweden; how did it end up at the LCM? Jnc (talk) 16:23, 24 June 2019 (CEST)

That's right, it did. It remained for many years in Peter Löthberg's storage. But last year most of the computers there, including MC, was moved to LCM. Larsbrinkhoff (talk) 19:47, 24 June 2019 (CEST)
Figured; didn't his KI10 wind up there too? Jnc (talk) 21:29, 24 June 2019 (CEST)
Yes, parts of the dual and sometimes triple processor "KICKI". And also KATIA (literally "KA-10" in Swedish), a CADR, and some other goodies. Well worth a visit if you're in town; ask for the basement tour. Larsbrinkhoff (talk) 07:01, 25 June 2019 (CEST)

Microword

Someone who looked at the schematics claims the microword width was 75 bits on the model A, and 76 on the model B. The additional bit is used to implement an improved CALL instruction. Larsbrinkhoff (talk) 07:29, 6 July 2019 (CEST)

Yeah, I vaguely recall something like that.

Version confusion

So EK-0KL20-IN-001 ("KL10-Based DECSystem-20 Installation Manual") gives, in Section 10.2 "KL10-PV Upgrade Procedure for KL10-C" gives instructions which clearly include the replacement of the main CPU backplane. However other documents make it sound like the Model B supports multiple sections. So now I'm completely confused as to the whole multi-section thing; I thought it came in with the Model E (AKA KA10-PV), and needed a different CPU backplane, but maybe not? Is the KL10-E different physically from the Model B, or not? Jnc (talk) 01:05, 7 July 2019 (CEST)
