As an unexpected freebie while I was picking up another pdp8 I've acquired a small pdp11/15. I'm really an 8-man so this is a bit of a foreigner but it seemed a shame to let it be thrown away. It seems to be a fairly small system in a single box but beautifully clean for a change ;o). The configuration sheet shows KC11, KF11-A, DL11, KG11-A, MM11-F, MM11-f, DD11-A and H720F which seems to reflect the contents OK. I've started browsing around but I'd welcome anyone giving me a rundown on what these modules build up to. I was quite interested to see the construction method with the cards upside-down in the backplane and a snazzy rotatable rack mount for servicing - unusual (to me at least). Bob
