I don't have an 11/20 (yet!), but I had a look at the KY11-A manual (no print set online, alas), and it does seem to show (pg. 19) a slide switch. Like I said, the 11/20 switch array looks exactly the the 8/E and 8/M ones (except for colour, of course), which seems to support that the actual switch is a slide. Anyone out there have an 11/20, and can give us definitive info? Noel

According to RFC-597, Illinois had both an 11/20 and an 11/50 (11/45 variant) running ANTS; other sites also ran it on an 11/40. > it had a custom logo panel for the top of the H960 racks, in red and > yellow, showing large ants crawling all along the cabinets. That could have been a local thing. At MIT, the first MIT-built LISP Machines, also housed in H960 racks, had custom logo panels reading "LISP Machine", with an illustration of a LISP two-part cell, with pointers (to other, un-shown, cells). I still have one... (the panel, not the CADR). Noel PS: In a previous message, I wrote "KA-11"; I meant, of course, 'KA-10'. Got -11's on the brain.. ;-)

PDP-8/e front panels.

Ah; the 11/05's (which is what I need switches for) use toggle switches (like I said, pretty much standard micro toggle switches, excepts for the front plate). I'm pretty sure the later 11's with complete front panels (40's, 45's, etc) used the same kind of switch. I was assuming all the PDP-x's of that era used the same front panel switch design, but apparently not. Or perhaps I'm mixing my eras a bit, and the slightly earlier ones all used the slide switch stuff (I just checked my KA-11 panel, and it uses slide switches). I think the 11/20 might have used the slide switches (its switch register looks just like the one on the -8M). Anyway, it seems like we all need both kinds! :-) Noel

Memory options for an HP 1000 (HP 21MX / 2112A)

by marc.verdiell＠gmail.com

Jay, I have gotten a M.E.M memory expansion board (two of them actually!) for my 21 MX. And many memory cards. So now all I need is the DMS firmware board. I am interested in yours if you still have it... I tried to contact you off-list but no success, maybe I ended up in your junk mail pile. I have gotten quite a few other boards so maybe I can get you something in exchange. Just contact me off list. Thanks, Marc >On Wed May 20 14:32:25 CDT 2015 >Jay West said: >I believe I have a DMS firmware board for the M series that is not needed, >I've passed on most all of my M series machines and focused on the E. >J

Ah! the old 8S ....thinking back on it this 8S was from a site we were actually paid to haul stuff away from as the land lord had the building rented to a new tenant. Date? had to be in 1981 or 82.. we also got a bunch of CDC washing machine early disk drives that were 6 megs or 10 megs that had 6 platters? and truckloads of old tape readers junk power supplies.. I remember trying to use it but alas to no avail... I would toggle in the boot and go look at it and it was all nonsense when I would read the display back. probably bad core drivers!? All this talk has me curious about it again... I will have to pull it out! a! the old days! Ed# In a message dated 6/8/2015 4:02:48 P.M.
