[Simh] In the DEC world, what was ZK3 ?

One of the recent discussions on this list mentioned ZK3 I remember it also appeared in numerous DEC publications, with e-mail addresses @zk3.digital.com, and, I think, in some DEC documentation (though I may be wrong on that point) What exactly was ZK3 ? I'm gathering it was possibly a

Re: [Simh] Problem with reading tape with PDP-11 SIMH

So now that Alan has TPC working, where and how do we document all this, i.e. the symptoms, the underlying SIMH design behavior vs the expected RSX behavior that cause it to manifest itself as a problem, and the DEP TS TIME solution, in an easy-to-find way so the next person doesn't have to go

Re: [Simh] Mark's mailbox full

I actually find it interesting how much it reveals about the target e-mail and account configuration We know he's running VMS We know he has a disk called $DISK3: We know his user space is under $DISK3:[MARK] And we know we've successfully filled his disk, thus denying some level of service and

Re: [Simh] vector images

Surely it is possible to extract files from SETUP.MSI without running the installer. Someone must have the tools to do this (either commercial or freeware perhaps ?). Another alternative is to run a virtual Windows OS image inside something like VirtualBox, thus avoiding any problems

Re: [Simh] DEC floppy disk interleave questions

Dying RFxx disks might be due to failure of FLASH memory in the controllers (either onboard the CPU or external chips). The charge in the memory cells in FLASH memory chips doesn't last forever, and slowly bleeds away. Early devices could fail after 10 years. Newer FLASH parts are better,

Re: [Simh] Booting the vax750 simulator.

Out of curiosity, I did a bit of Googling, and found a link to the following Digital Technical Journal article from 1992 that explains GEM in detail. It also gives the biographies of a number of the key players involved with GEM – I wonder how many Clem still has sitting in his office these

[Simh] Intel's PL/M-86, ASM86 and iAPX-86 Utilities source code

Sorry for this off-topic posting, but with all the recent talk about Intel's history of x86 development, I was wondering whether there are any "Intel connected" people around here who might know what happened to the source code for Intel's PL/M-86, ASM86 and iAPX-86 Utilities (LINK86, LOC86,
