Lyndon, Seeing as the folks who set up the original distribution are on the Yahoo list it's the best place to ask questions. I assume you don't want to set up a Yahoo account? Facebook perhaps? I did fight my way thought the Yahoo interface to get onto at least one of the MTS groups via the

Re: Attaching SIMH devices without halting simulation?

Typically you need to have devices online so the OS will see them at startup. But for removable media devices (tapes and many disks) you may want to mount the media (image files) later on, and switch them at runtime, exactly as you would do with disk packs or tape reels on a real computer.

Yes, but you were not able to attach in your startup script? That's when to do it. Bill Degnan twitter: billdeg vintagecomputer.net On Dec 31, 2017 3:59 PM, "Mark J. Blair via cctalk" wrote: > I've been experimenting with the SIMH VAX simulators a lot lately. The > only

Attaching SIMH devices without halting simulation?

I've been experimenting with the SIMH VAX simulators a lot lately. The only way I know of to mount a tape, disk pack, CD-ROM, etc. after boot time is to halt the simulation with ^e to get to the SIMH command prompt, ATTACH the desired image, and then resume the simulation with CONTINUE. Is

VAX/VMS & IBM 360 manuals from mid 1980s

Hi, A friend, probably in Ohio, tells me his father has 3 boxes (about 150 pounds) of manuals for VAX/VMS and IBM 360 from the mid 1980s. If anyone's interested in following up, email me and I'll send you the contact info. thanks, and Happy New Year! Stan Sieler

Re: DEC quad board rack

Noel, I recently I picked up a dozen or so spare boards for my PDP8E. I was wondering about how to store them. Some guys recommend some poly bags, others say it is important to protect against humidity. You sure have a boat load of cards, have you had any failures while in storage? Thanks Mike

Re: Computing from 1976

One thing that is starting to hurt with larger use of memory is the ability to access and load such large blocks of memory. I'm not saying that access speed haven't gone up but we are quickly reaching a wall, similar to the 4gig clock speed wall for the processors. Throwing more cache layers
