It is indead a VT52. ?It didn't come with the PDP11 but I am trying to

Vintage Computer Buds,
I dug out some cables and hooked up my Challenger 1P to my TV. Instead
of hooking the video directly to the TV like I did before, I hooked it
through a Magnavox Modulator that rebroadcasted the video signal on
channel three. This worked for some reason. Well, kind of. The URL is
to a photo of what displayed on the TV. It wasn't too easy to read,
but it is clearly some kind of ASCII character dump. No clue what's
going on. Do I need to invest in a proper old-style modulator like
they used on the Atari 2600 that will "split" the A/V signal from a
single RCA cable and then put it on channel 3? Per the website, [
http://www.old-computers.com/museum/computer.asp?st=1&c=813 ] that
looks to be the case...
Here's the output I do have. What the heck is my machine doing?

Hi there!
Sorry for the extra noise, but I don't know too many places to ask...
I've Always been a fan of DEC machines, and have owned severel VAX and
Alpha systems, but I've never owned a PDP. Might be fun. Anyone happen to
have or know of a MicroPDP-11/93 in BA23 pedestal with the KDJ11-EB board,
in fairly decent shape that they'd be willing to sell for good (but not outrageous)
compensation?
I've been warned that those might still be used in production, but gotta try
anyway... :)
Many thanks in advance!!
Hi,
someone wrote on this list, that the Disk distribution Paneel that is
mounted on the Back of the Backplane from some 11's are faulty and
will destroy data from the disks if two are connected.
I cn't find the posting now...
What kind of (wiring-) fault is this? Are there Fixes known?
Regards,
Holm

Hi,
does someone has a newer firmware Version for the UC07 as G143R?
I have a double UC07 in my 11/83 and have problems to get Disks
with 4Gbytes working. (DCAS-34330 50 pin). I have an Conner CFP2107S
wich has 2 Gigabytes, I can split the drive and successfully format
the resulting drives with XXDP or RT11. When I connect the 4GB Disks, even
when I fake the geometry to 2Gbytes, the controller successfully formts and
thest the drives, but an init du0: from updat in xxdp doesn't come back.
same with mdup.mu from an RT11 tape. It simply hangs.
Disk space isn't the concern why I'm trying to use the IBM drives, those
disk are quiet comparing to the conner 2107s, that is what I want.
Any Ideas?
Regards,
Holm

Howdy folks,
Trying to strike a deal in buying an Otrona Attache and a Dynalogic
Hyperion (or two) from different sellers.
The buyers didn't provide any asking price and are looking for offers
instead.
I realize there's few of these machines around, but they're not TOO rare
either.
Can someone give me a good idea what would be a good, fair offer on each of
these?
They all appear to be in mint working condition.
Thanks,
Anthony

What makes would you suggest, beyond Tektronix and Hameg, are there any

Not a lot lately. Mostly, I noodle around and see what text
games/apps I can port from the modern era back to a true 16-bit
machine (with limited process memory space).
Decades ago, before it was inexpensive to run UNIX at home, I set up
an 11/24 with dual RL01s. ISTR spending $300 on the 11/24 and at
least that much for more memory and a KT24 (I did not own the tape
drive - I did the initial setup on work hardware then took my own
packs home to run them). I went with Unibus because 22-bit Qbus
peripherals were still quite current with current prices, and the
11/24 was, compared to other options (11/44, etc), inexpensive for a
machine with enough disk and memory to run UNIX. At the time (mid
1980s), one could set up an ample RT-11 box for well under $1000.
UNIX on DEC hardware took a lot more resources than $1000 could buy
you in that era.
Simultaneous with these experiments, I was running UNIX on VAXen at
work - Ultrix 1.1 on an 11/730, Ultrix 2.mumble on a MicroVAX II, and
before either of those, 4BSD and System V on an 11/750. My first
experiences were on hardware that my employer paid well over $100K
for. I was happy to have something to run on my own that was around
1% of that.

Thanks Tony.
I guess there was a fair degree of customization possible at time of
ordering and the case decision depended a lot on the individual
customer requirement.
This machine has a controller for RK05 drives which takes 4 unibus
slots. It may have been the driver for the case choice.

I have decided to part with my PDP11/84 system, consisting of an 11/84 with
4MB Ram, two RL02 drives, and SCSI interface connected to 3 x Sony
Magneto-optical drives. There is also an Emulex terminal multiplexor, all in
a DEC cabinet, standing around 5' high.
The system is located in the South of England, and was working when removed,
some 5 years ago, but I haven't tried it since.
I would prefer the buyer to collect, and I can probably find a terminal or
two to go with it.
Email me for more details.
Jim.
In his two-part BYTE Magazine article entitled "Ease Into 16-bit
Computing", Steve Ciarcia stated:
"Intel is publishing an application note describing a small (seven
integrated circuits) multi-user Tiny BASIC system that uses the 8088."
Does anyone know of this app note, or have an electronic copy?

There was a thread "RQDX3 DEVOFFLINE Problems" in August / September 2011
where loss of low level format as result of two drives having the same drive
select jumper (or possibly different drive select jumpers when the controller
expected them to be the same) was discussed. Perhaps that was it?

Every so often, a discussion of Tiny BASIC appears around here. I was curious about one of the very first versions of Tiny BASIC, the 8080 implementation done by Whipple and Arnold, as documented in the Vol. 1 No. 1 (Jan 1976) issue of Dr. Dobb's Journal (of Tiny BASIC Calisthenics and Orthodontia)
This issue contains an octal listing of a Tiny BASIC interpreter for the 8080, and I couldn't find this version available for download anywhere. So... I typed it in, and it works!
I documented my work, which is available at
http://oss.readytalk.com/tb/tinybasic.tar.gz
(Note - this location is temporary - I need a home for this if anyone is interested)
Included are the text file for the octal listing, a binary which can be loaded into memory, an attempt to extract the IL from the binary, and some instructions on bringing up Tiny BASIC. I was able to run some simple programs with a Z80 simulator that I've been running, and it appears to work correctly.
I found the PDF of the listing in the ACM digital library:
http://doi.acm.org/10.1145/987491.987494
Typing in octal listings is error-prone enough, and typing them in from bad PDF scans of bad photocopies is even trickier. I have corrected many errors, but I'm sure there are more. If any kind soul would be willing to proofread / correct the listing, it would be **GREATLY** appreciated.
I hope this is of interest to people. I'm very interested in other versions of Tiny BASIC out there, if someone has ever typed this listing before, etc. I'm familiar with Tom Pittman's work, but other resources would be greatly appreciated.
-Eric

Re: Nature's Miracle
I did end up using several enzymatic cleaners over the course of a few
months. I don't recall if Nature's Miracle was one of them or not. I
also used Anti-Icky-Poo ( http://www.mistermax.com/ ) which, rather than
being a bottle of enzymes, is a solution that actually contains the
bacteria that *make* the enzymes. After a liberal dosing of that stuff,
as long as you keep the area moist and there is (non-crystalline) urine
or other waste products for the little buggers to munch on, they
*should* keep working.
I was able to get the stink down to the point where it was no longer
offensive to be in the garage (where I was storing the cabinet) but not
to the point where I'd bring it into the house.
and on the idea of replacing the power supply with a switcher:
I was actually going to suggest that if nobody else did in last night's
digest. You can probably find a switcher that's more efficient than the
original linear supply and fits in the same volume as the original
supply. PLUS: nothing says that once you've got the switcher installed
and the PDP-11 powering on that you couldn't continue working on trying
to rehab or rebuild the original supply. Once you got the linear rebuilt
and working, you could swap it back in... and I'm sure you'd be able to
find a different use for the switcher. Or, if nothing else, you ought to
be able to resell it.
