RT-11 Bug Fixes and Enhancements
|
| |
I am a VERY addicted RT-11 hobby user who enjoys the challenge of fixing bugs in the RT-11 operating system as well as producing enhancements. Is there anyone reading this who would find them useful, let alone anyone who would want to share in at least defining what is done and how? One of my long term goals will be a Y9K set of bug... more »

|
| |
Hi, probably should send this to the simh list, but I'm not a member. Does anyone know about KE11A (EAE) support in simh? It doesn't look like it's there. Before I go add it, I was wondering if someone else has or if I'm confused. thanks! -brad

PDP 11/84 software re-install help needed!
|
| |
Hello Everyone, I posted a message a couple of months ago regarding the failure of the UNIBUS card on the 11-84 I'm running. to re-cap the story, the system was coupled to a WARP drive, a sort of primitive RAID array, that held the RSX-11M operating system and the drivers and software for the machine the PDP is running.... more »

Looking for Alan Frisbie
|
| |
I'm posting here because I mostly associate Alan with the PDP-11, and figure that someone who knows him will let him know I'm looking to get in touch, if he does not see this himself. He doesn't appear to have posted anything to Usenet (at least under a recognizable name) since November 2004. This inquiry is specifically in reference to IMLAC vector display processors.... more »

Building a computer with the J-11
|
| |
I recently purchased a J-11 chip on eBay, and have obtained the user guide by searching the web. I am intending to build a single-board computer with it, but I have a couple of questions: What speed of crystal should I use? Speeds from 3.75MHz to 18MHz have been mentioned on websites. I think I have one of the later chips... more »

Suggestions for "the fastest" Q22/SCSI-interface?
|
| |
Dear list members, I'd like your "educated opinions" upon which SCSI-adapter that would be "the fastest" for the Q-22 bus... (if that can be achieved without starting a "religious" fight...) I've seen some indications that CMD's CQD 440 would be a candidate, but on "bitsavers", I can only find a manual for CQD 420. What would... more »

Strange RLV12/RL02 problems

I've verified that everything is connected up and terminated correctly and the most things seem to be working fine. I can boot from RL02 and the drive passes diagnostics without error. Under specific (and completely reproducable)... more »
