Anybody in the US happen to have spare drive rails for a Casetek 1018 case? The 3.5? ones are model 1018205 and the 5.25? ones are 1018202. If so let me know what you have an how much you want for them.
Thanks
TZ.
P.S. I hate custom mounting rails in cases.
Does anyone reading this list still write code to be run
under RT-11? When a program has a bug, what do
you use to find the problem? For debugging programs,
SD: seems the most efficient way, especially when a
Mapped Monitor is being used. Alternatively, ODT
(VDT when Multi-terminal Support is included in the
RT-11 monitor) can be LINKed into the program.
Recently, I have been considering enhancements to
the SD: variant, SDHX.SYS, which would reduce
the Low Memory required along with adding an
additional feature which is part of Ersatz-11.
Specifically, SET PCLOG ON requests the
Ersatz-11 emulator to save the addresses of the
last 64 instructions that were executed. The the
command SHOW PCLOG displays all 64 addresses
at the users request.
I would appreciate a response from anyone still writing
and debugging programs that run under RT-11 and
which debug package is being used along with the
advantages and disadvantages that have been found.
One big advantage of SDHX.SYS (actually all of the
SD: variants) is that the user can request an automatic
display of all of the register contents every time that a
breakpoint occurs. The display occurs at the top of
the screen each time the breakpoint takes place. The
VT100 escape codes are then used to scroll down the
screen and display each instruction in turn as it is about
to be executed. One big disadvantage of SDHX.SYS
is that it freezes the system completely, including the
clock interrupts.
The big advantage of VDT is that other jobs are able
to continue running, but no other information is easily
available when the program is stopped at a breakpoint.
I would appreciate any response.

I now have over 40 recyclers across the country looking for items for
collectors. Below is a list of what is being asked for.
If you want to add to the request list, that is fine.
The scrappers are asking for pictures. Remember that to them, this is just
junk to be parted out; they are unfamiliar with the equipment.
If at all possible, PLEASE send me a LINK to a site that has a clear
picture, maybe some discussion about the machines in question.
The stuff I look for is very general terms...ESCON and FICON are the names
of the interconnects used to connect the machines to their disk arrays.
ESCON is older (but still common) and FICON is current. The earlier one,
called "Bus and Tag" or "Parallel Channel", is also something I can use, but
they're very old and much less common.
Models to look for are 3880, 3990, 3390 (much older), and "RVA". These will
typically be biggish, very heavy cabinets containing drives and a
controller.
MicroVAX 3400, 3500, 3800
HSC50, HSC70
Any whole or parts of VAX 11/780, 11/785, 11/725
VAX 6000
RA9x, RA60, TS11 drives
Any software and manuals for VAX machines
If you don't know how to test, they request that you NOT even try to power
the equipment on; they will buy it as-is.
IBM PS/2 Model 70 A21 (specifically)
IBM PS/2 Model 90
IBM RT PC 6150
IBM XT 370
Sun 386i
SGI Prism
Memorex 1270 Terminal Control Unit (used on IBM mainframes as an alternative
to 270x TCUs)
Memorex 620 (2311-11 equivalent), 630 (2311 equivalent), 660 (2314
equivalent) or 3660 (2314 equivalent) disk drives or the DEC OEM versions,
the RP01, RP02 or RPR02 disk drive
One terminal I have been looking for specifically for quite some time is the
Ann Arbor Ambassador
I'm always on the lookout for a Durango Systems "Poppy" PC
It's unlikely because they were unpopular, but a specific Amiga I'm casually
looking for is the CDTV - the one in the black "audio component" case. It's
essentially an Amiga 500 with CD-ROM that looks like a VCR or stereo
receiver. If you didn't spot the Commodore logo, you probably wouldn't
notice it was a computer if you saw it in a stack of stuff.
I am looking for scientific and industrial minicomputers from the 1960s and
1970s with "switches and blinkenlights" front panels.
Digital Equipment Corporation (DEC) PDP-4, PDP-7, PDP-9
PDP-8 and older PDP-11 models with the blinkelights
Data General Nova, Honeywell, Modcomp, and others as well.
I'm specifically looking for these machines from Computer Control Company
(3C), likely labeled Honeywell (after an acquisition): DDP-24, DDP-124,
DDP-224, DDP-416, DDP-516, H316. These are large machines in 6-ft racks or
4-ft cabinets. Also Datacraft 6024 and early Harris machines.
Probably a longshot, but I'm still on the hunt for JC80 series equipment
that was made by Johnson Controls. The JC80 was a building automation
"computer" that was made in the 70s/80s. I also wouldn't turn away other old
Johnson Controls stuff from the 1980s or 1990s such as JC85, DSC, old
Metasys, etc. My father once serviced these systems so I'm very familiar
with them. They are not the kind of thing that anyone who collects old
computers would likely want, so I suspect that 99.9% of them have been
scrapped long ago. I'd be willing to pay scrap value plus 10%, which
probably wouldn't be all that much anyway since these things are big heavy
steel boxes and racks with a lot of empty space inside. Because this sort of
stuff is so specialized, I wouldn't expect anyone to test it, and in fact it
would probably be safer not to try to test it since it would need repairs
and maintenance before it would even be safe to power up.
For me, non-PC keyboards are important - pre-ADB "Classic Mac" keyboards or
Amiga, especially Amiga 1000 keyboards in particular. I'm big into
Commodore, so anything pre-C-64 is also interesting (PETs, VIC-20s, disk
drives, some printers). Old external disk drives (single-sided Mac and any
Amiga) are also useful and interesting.
a complete Royal AlphaTronic PC system - with monitor & at least one of the
floppy drives. This is what it looks like:

Any VAX mainframe computers, or any old DEC 6' cabinets that are populated.

Other large old interesting monsters, let me know what you get in?

No, the HDA was stripped bare.
I do have the spindle.
I also have 3 RA82s and another RA81 (that goes to Dave McGuire once we
figure out how to get it there without hurting it (within his budget)).

Woohoo! :D Not only I'm 39 now, but also got a gift from a fan of my

A brand-new-like, boxed TI99/4A :oD
I'll take some pictures and add in www.tabalabs.com.br tonight :oD
Niiiiiiiiiiiiiiiice! :D

Just in case anyone's interested, I've finally gotten around to cleaning
up the PERQemu source to the point where Idon't feel too ashamed to show
it to others. (It's still a bit messy.) I meant to do this years ago
but kept putting it off.
I'm releasing it under the GPLv3 in the hopes that maybe some other PERQ
fanatic can finish what I started (or at least use it as the basis for a
different implementation). These days I have too many other projects
occupying my time to spend much time with it, and I kind of got burned
out on it a few years back.
http://yahozna.dyndns.org/projects/PERQemu/source/PERQemu-source.zip
(And you can read more about the project at
http://yahozna.dyndns.org/projects/PERQemu/index.html)
And a big thanks goes out to our own Tony Duell for his extremely
patient help with this project; the answers he provided to my questions
when I started on this project back in 2006 could fill a small book :).
And thanks to Al & Bitsavers for the scanned documentation and archived
software. Without these this project never would have gotten started.
Thanks,
Josh
