    PDP-11/34? in Cirencester, Wiltshire UK

    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.

    DEC/X11

    I looked after several 11/70's in late 80's to early 90's running RSX-11m. After any odd failures we would run IOX (I/O exerciser) that was on the RSX-11m boot disk.

    PDP-11/93 Back Panel

    DEC 4000/500 with no Operating System

    These usually come in a BA400 enclosure that may contain some DSSI disks and a TQK70 tape drive. Can you post some photos of the inside front so we can see what controllers it has and if it has any storage?

    Build attempt for PDP-11 from spare boards - will they work together?

    I'm not sure if you are planning on using the DHV11 to obtain console port, don't think it is supported?

    LK07 (VT100, etc.) keyboard oddity.

    Teletech, slightly off topic but...in your second photo the keyboard is sitting on top of either a BA11-VA or a TU58 drive (possibly something else!) I have a BA11-VA based 11/02 running RT-11, I'd be interested to know what you are doing with yours, perhaps in a new thread. Thanks.
