Re: DEC backplane power connectors

Thanks much. I think I found the mating plugs I need on the te.com site and digikey has them. --tom On 1/27/21 2:05 AM, Mattis Lind wrote: > > > Den ons 27 jan. 2021 kl 06:59 skrev Tom Uban via cctalk >: > > Are the power connectors on the DEC PDP-11 backplanes

Re: DEC backplane power connectors

Well, they vary for what you may need of course, but in my case, I wanted to connect to existing DD11-DF female shell/male pin 15 and 6 contact connectors. Searching the te.com site, there are some similar parts, but the ones which look correct are: Commercial MATE-N-LOK-S, 1-171196-0 (digikey

I wish I had seen it before I ordered. I may have gotten the wrong 6pin shell. --tom On 1/27/21 11:51 AM, Noel Chiappa via cctalk wrote: > > Are the power connectors on the DEC PDP-11 backplanes (e.g. DD11-DF > > 15pin and 6pin) Molex or other? > > Are they still commonly available? >

Re: DDCMP sync?

Actually, DMC and DQ11 both had V35 options and both would hit 1.5 (1.3 actual due to protocol overhead. The DP8/e supported v.35 also, but I don't recall how fast I could get that to go. I had bell 301 and 303 modems in the lab in the mill, running back to back. THere are some arcane bits in the

> I may have gotten the wrong 6pin shell. I have this very vague memory of some similar connector shell, but I have no memory of what the difference is. I just checked the shells I have here, and they definitely fit onto the power harness on an -11/40; and the numbers on the Web page are corr
