At least a little of that does shine through.
"The Hitchiker's Guide to VMS" has many tidbits up through the V5 days. Bruce Ellis, 1990. And even better it's enjoyable.
There were various detailed things in DTJ, although those typically represent more of the corporate mongolian-horde design-by-committee approach to systems programming, rather than anything you'd want to actually emulate.

Probably borderline for CCtalk, but does anyone have a proper programming manual for the Iomega ZIP drive ( 100MB atapi version ) ?
I need to know exactly which ATAPI commands have been implemented.

Note: I'm not asking about VAX hardware architecture, but about the
software architecture of the VMS operating system.
What were it's design goals?
What were the design trade-offs made that resulted in the specific
choices for VMS? Process scheduling? I/O? etc.
Is there a good book on this subject?

Tsk, tsk, Ethan, you know better than that ;-)
A PET with a working video section and video RAM removed will show the
classic checkerboard pattern or under certain circumstances a pattern of
small black squares.
No doubt there's considerable PET knowledge on this list, but as Terry
suggested previously the VCF forum or one of the PET/CBM-specific lists
might be a better place to find help with a sick PET...

Hi
You wouldn't have a copy of the reference disks for your rm pc-386 as I have
one and am unable to setup it up as I cant get into the bios etc
Any help would be much appreciated
Cheers

Subject: straight-8 miniaturised
Who was the one with the wacky idea of building a Straight-Eight PDP8
using flipchip cards populated with surface-mount parts? I have a
hankering to run some numbers about it.
There's some guy in Germany who built a complete computer using
discrete components, mostly resistors and bipolar transistors
(no ICs), but all surface mount. It was quite small. I can't find the
link now, but there are a bunch of homebrew computer projects linked
to here:

Hi,
I'm thinking of getting my Zilog System 8000 maybe one day
back to life... this includes multiple tasks.
- get a working harddrive
- get a working tapedrive
- get access to tapes containing the OS and the diagnostics
Right now I'm thinking of the tapedrive part.
The original drive is a DEI CMTD-3400
http://www.bitsavers.org/pdf/dei/CMTD-3400S2_4tk6400bpi_1979.pdf
I have one but it is broken in multiple ways
- the previous owner I got the drive from replaced it in the 80s
as it was failing (no further details available)
- the motor does not run smootly - it does not start on its own
when powered up and the UPM is changing. I was not able to open
it.
- the rubber wheel went to fluid (usual problem...)
I now got a so called "Quantex 2200" which is a 19" case with
two Quantex 650 drives which should be able to handle the same
tape format as the DEI drive.
All I was able to find about this drive was:
http://www.bitsavers.org/pdf/quantex/TM1001_650_Jul81.pdf
Does anyone have any experience with this drive? I wonder if
I could make it "connection compatible" somehow with the DEI
drive. The manual itself talks about a controller board which
is the only whay the drives can be bus driven - it looks like
the drives in this 2200 case do not have this optional controller
board. Maybe they do not have it because the big plate in top
of the case is a controller board for both drives...
Who knows - I did not find anything usefull about this 2200
case nor how it is supposed to be connected to what (pinouts).
The rubber wheels are as well went fluid.
I could also need some ideas how to get a QIC drive capable of
reading and writing DC300XL QIC cartridges hooked up to a PC
with BSD or Linux running as in some point in the future.
I must be able to copy the system tapes (reading + writing) with
a PC.

Do you remember Grant Stockly of altairkit.com? Whatever happened to him?
The site is still up and running, but it hasn't been updated since 2007.
The forums there are choked with spam. I'd love to see what he's been up
to and maybe buy a kit from him.
