    Ampex SP-300

    I hope this isn't too far off topic but there has been a previous thread on digitizing NASA tapes so here goes. This recorder is 7-track and takes 1/2" tapes. I intend to use it to look at some NASA telemetry tapes. The problems are 2-fold. First I would really like to get hold of a manual (and...

    Dilog DQ419 Floppy Controller with Shugart 860 Floppy Drive on LSI-11/23+ system

    Using a 3M SS,SD diskette I did a low level format under ODT. Then running a TU58EM emulation of RT11v4 I did a format and an initialization. I got illegal directory messages after each step. Next wanting to see if I could read a diskette I obtained a 3 diskette set of an RT-11 V4.0 Autopch. I...

    VT320 problems solved

    Replacing the driver and DUART ICs fixed the printer port but not the DEC423 port. With the terminal connected to the computer I discovered that if push the plug in and up (and hold it in place) it makes connection and the terminal works as it should. I then did some connectivity checks with...

    VT320 problems

    Here are some clarifications on my connections between the VT320 and my 11/23+ system. The terminal only has DEC-423 connectors, no DB25. The attached documents show the pin assignments for the 6-pin DEC-423 connector, the cable used and the adapter to go from DEC-423 to DB25. The adapter then...

    VT320 problems

    Now that I have my 11/23+ system running I wanted to try using a real DEC terminal. Connected a VT320 to the computer and all the boot up information appeared on the screen. However, when I went to respond the terminal is apparently not sending to the computer. I have the cable from the terminal...

    Bootable RX01 diskettes with RT-11 and XXDP

    Yes, I would be delighted to get TU58EM running. Figures 1 and 2 show the computer monitor and the TU58 emulation respectively. This attempt was using a KDF11 and booting from a BDV11 board with updated KDF11B ROMs. Figures 2 and 3 show a current attempt this time using a KDF11B (of course no...

    Need help with 11/23 system

    System consists of LSI 11/23 (M8186), MSV11 (M8059KF), DLV11-J (M8043), RQDX3AA (M7555), and BDV11. These are in what was a MicroVAX II box. Thanks to help on the forum I burned a set of 2716 EPROMs as KDF11-BJ ROMs. Using PUTR I created what I hoped would be a bootable RT-11 disk for the RX50...

    EPROM Programmer Recommendations

    After some trials and tribulations I got the Willem Programmer hooked up to the parallel port of a computer. I then placed a 2716 (supposedly blank) eprom into the programmer socket and checked to see if the 2716 was indeed blank. Apparently none of them read as blank. They all read as shown in...
