I've been in conversation on Facebook group "DEC Computer Users" with someone giving away a PDP-11/34 in UK. He sent me some photos today but is in too bad a condition for me to want it. It looks to have a complete PCB set to me. With DL11, DL11-W, RX11 and RK11. So if anyone is interested and...

I've had a DECSystem 5000/240 for a while and recently decided to check it out. I cleaned it up and tested the PSU offline and it appears OK. I connected the PSU to the system board via the large ground and +5V cables only and no issues, PSU fans turn and some LED's are active. I switched it off...

Hi, I'm looking for jumper and switch configuration for an Emulex CS21 F. I'm looking at putting this in my 11/24 to add load to the PSU. From what I gather from a Google search the F version was only supported with VMS but I guess as it is Unibus it will have the same electrical and signal...

Does anybody have experience troubleshooting a VT420? I have one that does not display on screen when powered up but makes a continuous clicking sound (switch mode startup?).

I'm struggling to find where I can find the iso images for download, if indeed that is how I get OpenVMS. I've also gone to the HPE license site...
