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?

I found an H720F power supply. Anybody knows where it is used for?
I't a self containing unit, it's not using the bricks and it does
not ring a bell for me.

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?

Sounds like a music critic to me...

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.

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.

A: Because it fouls the order in which people normally read text.
Q: Why is top-posting such a bad thing?
A: Top-posting.
Q: What is the most annoying thing in e-mail?
I have been given a PDP 11/04 (at least that is what the front panel says
and it does have an M7263 CPU board) to look after for a few years while
the owner is away working and am quite keen to try getting it operational.
I have no idea when it was last run so will be going through the full
capacitor reforming process/etc.
I am not a DEC expert (they are not really common down here in New Zealand)
so am relying on a lot of the info on the net. Everything I have read
suggests that 11/04's are in a BA11-L chassis with an H777 power supply (
http://www.brouhaha.com/~eric/retrocomputing/dec/pdp11/chassis.html). This
unit is in a BA11-K chassis with an H765 supply. Is this normal or is it
possible that the machine has been repackaged at some point in it's life?

Andrew
