PDP8/e programmers consoles

by chd＠chdickman.com

So the PDP8/e used the KC8-EA programmers console which has incandescent indicator lamps and the PDP8/f used the KC8-FL programmers console which has LED indicator lamps. Why? The maintenance manual says that LEDs are more reliable. The operation is as far as I know the same. The LED version doesn't need the +8VDC supply, but that seems an advantage for it. I remember reading that the EAE had some revision dependencies with the console, so were there bus timing problems with the LED console that limited it to short buses? Maybe this changed over time, but it overlapped long enough for them to have both described in the maintenance manual and specific to the application. Another console question... Has anyone ever seen a PDP8/i style console for the PDP8/e? Looking at the way the PDP8/e console functions, it should be possible to time multiplex all the register to the data bus so they are all visible at once when the machine is halted. -chuck

AlphaServers

by john.h.blake＠gmail.com

I've got two, the first being an 3000/400 64mb with two 146 gb SCSI-320 drives running on converters, one with openBSD 6 and the other with openvms 8.4 running headless. I doubt I'll ever be able to find the monitor, much less the needed cables and keyboard/mouse to turn it into the desktop it was supposed to be, so I've got a color turbochannel framebuffer if anyone has any use for it. The second is an alphaserver ds10l with the 617mhz EV67 processor, 1.5 gb ram and a radeon video card on the sole pci port, which runs openvms 8.4 on one hard drive and the most recent available version of unsupported debian linux on the other (I think it's sid?) as a workstation. Nekochan.net is a fair resource for hobbyist knowledge, possibly the only place online where people are still futzing about with Tru64. comp.os.vms on usenet (or the info-vax email gateway) is where all of the latest news and deep tech discussion goes on. vcfed.org has a very healthy DEC forum too.

Andromeda Systems DC11

by bill.gunshannon＠hotmail.com

I asked this on USENET, I don't suppose it would hurt to ask here as well. Anybody here remember the Andromeda DC11? More importantly, does anyone still have Andromeda stuff laying around? The module used something called "Personality Cards" which were actually just connection adapters for different kinds of disks. I am trying to find a couple (I'd be happy with one) WPC8F adapters for connecting 8" disks to my modules.? Any chance anyone has these taking up space?? Of course, I would also take other kinds of adapters, well, except for the WPC5FA.? That's for the RX50 and even I don't have any more of them left. bill

LSP10-NW (printer interface for KI10?)

by mattislind＠gmail.com

I have received this for a retired DEC service engineer: https://i.imgur.com/pJkcsHe.jpg?1 https://i.imgur.com/zwpSbrg.jpg According to the label it is a LSP10-NW made by DEC CSS. Previous owner claims it is for a KI10. I don't really know. I have no real use for it except for the flip-chips. Anyone has a need for such a thing or just the backplane? /Mattis

Quad density Pertec

by gerardcjat＠free.fr

Reply to :I note that the Kennedy incremental 7 inch reel drive in the NASA flight case hasn't attracted a lot of interest. That sample tape that I got, however does verify that the parity track on this telemetry stuff is unused. So that explains the 8 data inputs with no parity on the NASA model. --ChuckWell, at least ONE person was interested ... Me .... BUT the vendor does not offerinternational shipping ( to France ), and does not care answering mail :-(Though tape transport is already "packed" ;-)Gerard
