I have a DEC KBD01 for trade. Unit powers on but does not come with the key. I believe that the KBD01 is for use with a PDP-11/44 for remote support. I have just acquired a PDP-11/34 and I'm looking for parts for that. What have you got to trade? Thanks.

Thanks for the heads up :)

Thanks Don, I'll keep that in mind. I only have one DL11-W so won't be able to run one of the TU58 emulators with XXDP, so I'll be needing a way to run XXDP and your project sounds ideal. (y)

I got the RX02 with it also. I probably wont use it and will swap the controller and drive for something that I will use. I guess It would be expensive to ship drive and controller to Australia. Interestingly the only two boot ROM's on the M9312 are for RX01 and RX02 and there is not RX11...

The 11/34 contains two backplanes with PCB's listed below,

Thanks Tom, I found your thread shortly after starting my post:). The power supply observations that you mention are certainly points that I will follow and check on my PSU/regulators when I start to disassemble, clean and test my power subsystem. I've started to catalogue the PCB's in my system...

I picked up a PDP-11/34 earlier this week. I plan to strip it down, clean all the components and then start on testing the H765 PSU components. I plan to test each of the regulators on the bench. I have a 25V 2A AC supply and I have the necessary resistors to load the PSU to 1 Amp, 2.5 Amp and 5...

I have a DECsystem 5000/240 and it has no room for internal storage. I have an external SCSI disk connected and running Ultrix. I plan to migrate to ZULUSCSI also.

I have several of this style of DEC module DECxxxxxxxxxxxx and some of them have this type of damage. I think it is down to age and that the material has deteriorated. I opened one of my modules and every tab snapped off. I had the same issue with a TLZ10 DAT, I carefully tried to remove the...

Is it a "TNC Connector"? Similar to a "BNC" connector" but threaded instead of bayonet.

I have one, with an 11/02, MSV11, MXV11, SCSI and SCSI2SD running RT-11. Hmmm...$1750:unsure:

Interesting J-11 based controller on Epay. Oddly listed as a DEC M8190...

Good work, You have a HDD (RZ28D) in there, you could check if it has an o/s by typing "boot DKA0:" without ""

Go for it! I have a 200 4/233. It's a good machine, mine is running Tru64 with an extra external disk shelf. If it doesn't come with a hard disk then I would recommend purchasing SCSI2SD or the newer ZuluSCSI.
