> And on another note, is ZXTAPE sensitive to cpu speed?
Absolutely. I went through 4 PCs before I found one
(a '286) which worked with ZXTAPE. I set the '286 up
in a corner as a file server for the ZX81 several years
ago and fire it up as needed.
Another author (with the permission of Wilf Rigter)
has made available a version of ZXTAPE which claims to
run well on Pentium-based machines, but I've no experience
with it.
Regarding software -- all you could ever want can be
found at these links:
University of Trondheim:
ftp://ftp.nvg.unit.no/pub/sinclair/zx81/
Official ZXTEAM site:
http://www.zx81.de/
The World of Spectrum:
http://www.worldofspectrum.org/
The last is primarily a Spectrum site but has quite a
number of ZX81 programs available as well.

Hi,
does anyone know of an on-line manual for the RQDX3 disk controller?
Thanks
Jim.

My wife is trying to free up some space, and wants to sell her
Commodore 1084 monitor.
She is not into computer collecting, and has used it as a display for
her video camera.
It is manufactured in october, 1989.
Serial number is XT 1070699.
It is a nice little monitor for composite or s-video. The digital rgb
is not all that great, but I suppose that is a natural consequence of
the standard.
My wife only used it with her previous video camera, so I do not think
it has logged all that many hours.
In any case, she bet it was easier for her to sell it on eBay, but I
was allowed to tell the list and solicit offers. We are in Pennsylvania
right now.

I still have a Tandy 1000 with monitor and printer, several IBM XTs and
IBM ATs, some Corona luggables, and some Compaq luggables.
All available free for anyone that wants to pick them up in Northern NJ
(Ridgewood). I'm also willing to deliver to anywhere along my normal
travel routes (um, well, that is still Northern NJ, but I go to Wayne on
a fairly regular basis).
They are taking up space that I need to recover. I've lost interest in
them, but I can't bear to throw them out.
I'd really rather not ship due to the time/effort involved, but if you
can't pick up, and are too far out of my range for me to deliver, and you
really want one, let me know, maybe we can work something out.

I visted Thom again yesterday and here's some of what I got.
<http://www.classiccmp.org/hp/PDP-8%20cards/carfull2.jpg> That's two boxs
of DECMate and Rainbow docs, a big pile of loose VAX docs, two DSD-440
drives and about five boxs of cards (mostly PDP-8). In other words, another
car full!
<http://www.classiccmp.org/hp/PDP-8%20cards/carfull2-l.jpg> Yes, that's
another box full of Cab kits in the middle! The cards in the boxs in the
near box are NIB prototyping cards! :-)
I brought home a car full last Monday but I already unloaded most of it
but here's a teaser showing some of it.
<http://www.classiccmp.org/hp/PDP-8%20cards/car%20full3.jpg>. These are
all PDP-8 cards.
Happy Collecting!
Joe
Can anyone id this card?
<http://www.classiccmp.org/hp/PDP-8%20cards/SMS-what.jpg> I can't find
anything that looks like a model number on it and it doesn't match the
drawings of the three SMS cards on Bitsavers. The most noticable difference
is that the other cards have lots of jumpers all over them and this one
only has a few (7) near the edge connector. The package that it was in only
says "Q-bus SMS Disk IO Bd". The markings on it are Prog Assy 1011939-0002G
(the G may be a 6), Assy No SMS 0003773-0001C, Fab 0003772-0001/c2, AW
0003771/B. Sorry for the crummy picture.

Hi
It is just rude to not ask.
Dwight
Hi folks,
We just got a brief note at ibm1130.org from a guy who spotted
an IBM 1130 "looking in a bad state in the street out the back
of the ibm edinburgh office."
I don't know yet if it's still there now -- this could have been in
1975 and he just got around to looking it up -- but is there anyone
in or near Edinburgh who might have the interest in rescuing it, if
it turns out not to be a false alarm? At the very least, it should be
inspected to see if any useful parts could be salvaged from it before
it gets hauled off by the garbage men.
Please let me know if you can help if it pans out. I'm trying to see
if I can get more details.
Brian
What programmer can I look for that has the ability to program a
2708?

The easiest ones to find will be Data I/0 29s with a Unipak or Unipak 2

Hi,
thank you all for the tips around my harddrive desaster. Next time I
will be wiser.
I have cleaned my removable disk's heads. Used isopropanol and a match.
Tried the crashed disk pack, crashed again immediately. Had to clean one
head again. Took another pack. No crash, no error display etc. Hope that
it stays ok.
Now I did:
> $dm4
.. And dm0,1,2,3 work same way....
Computer says:

I would be glad if that is a message read from the disk partitions (like
the bootsector message on non-system disks in my pc).
When I boot dm5 (the Emulex controller configuration emulates 6 RK06
drives, don't know which one is the removable pack) the disk does
something (little seek operations), endlessly.
Busy light on the controller nearly always on and the disk seeks around
one position. Endlessly. No error indication. When I stop the CPU,
controller and disk activity also stop. When I let the CPU resume it
goes on and on and on. What's that? A strange program? I have waited for
nearly 10 minutes without any visible reaction. Seems to be reproducable.
What is the "modern way" to get software into the PDP11?
Is there anything like a RIM or BIN loader?
Has anybody a convenient solution - or do I have to start from scratch
writing my own tools?
Best regards,
Philipp :-)
