DEC BA213 and BA213 S-boxes?

Hi, All, Watching some of the recent traffic about what newer Qbus boards will and won't work with 2.11BSD, I've remembered a thing I was once looking for. Back when I did DEC hardware for a living, we stopped buying new stuff after we got a MicroVAX-II. As such, I have plenty of LSI-11 to

RE: Identifying an aluminum panel

Not knowing what the size actually is, it looks familiar. Given the bootprints on it, it looks like it's a pretty good-sized chunk of aluminum. It reminds me of the back panel of some of the Sun 3/2xx and 4/2xx server chassis. Large, heavy switching power supply and backplane inside. Even

How to set DZ11 line speeds under RT-11 V4?

Hi all, I've now had some success getting MU-BASIC configured and running on multiple terminals under RT-11 V4 in simh, with a hardware configuration similar to that in my real PDP-11/45. I have a serial console + DZ11 in both configurations. When SYSGEN-ing RT-11 V4, the only speed

break on pdp11 serial ports

Hello all, I've been playing around with some ideas for designing some hardware to connect peripherals to an fpga for my vhdl pdp-11. One of the things that should definitely be on there, next to sd cards and leds... are some serial ports for console terminals etc. I've spent some time to

I think I have made some progress. I bought a new scope (TDS420A) and now I can actually measure things. My old scope was far too slow. It turns out the radial alignment was *very* off, so I have corrected this. If I disable the seek timeout error, the heads load onto track 0 and the READY lamp is
