hmm.. also in looking through the xenix docs I see mentioned, the DT-1.
I've got a PT-210 and pre-coco vidtex and have been looking for a DT-100 but
dont remember the DT-1. What's it like?
- Mike: dogas(a)leading.net
Having had a small chance to digest the new trs pillsI find that I newly
have:
- a 6000hd 15meg 1d that I'm currently running xenix 3.01.00 on
-a 16 1d that is missing some internal cables, this one has an odd model
16 vanity plate and matching keyboard.
-a 6000hd 15meg 1d
-a 16 2d with a bad floppy and intermittant keyboard
-a 6000 15meg 1d
-a 6000 15meg 1d
-a 16b 2d with a bad monitor
-a 16b 2d
- keyboards for 6000 (and a white key one) 12, 16, and 16b
- 8meg hd system (big black)
- 20meg hd sytem (small white)
- 3 extra 8" floppies
- a bad 15meg winchester replacement
- assundry cabling
And digging into the closet (past all the skeletons) I pulled the following
software out of stasis
- xenix basic interpreter
- model II cobol dev system
- versaledger
- scripsit
- multiplan
-profile plus
- ar/ap/payroll
- trs-dos
- videotex Plus
- trs-dos II
- trs-dos 4.0
- model 16 system disk
- xenix CTAR
- profile 16
- xenix 3.02.00
- xenix profile upgrade
- xenix multiuser upgrade
- profile 16 upgrade
- xenix 1.3.xx for model 16
Will the trsdos stuff above work under tsh?
Now to dust off the drive heads and install some stuff. If anyone has any
complimentary warez or needs copies yada yada yada.

I didn't forget them... I never knew about the LE8 nor the LP14, and I didn't
know that there was ever an interface for the LP25 for any model of 8. It's
all news to me.

I have only ever seen PDP-8's used with what would be termed "personal" class
printers.

I have heard of the LA30. I didn't know it was parallel. Never seen one.

That's how it's supposed to work. If you look in the tech manual for the
processors, you see that there's a 16-bit register for the "low" part
of the ODT address, and another register for the high part of the ODT address,
but there's no carry connecting the two.

Absolutely. In fact, some configurations had only a 2Kbyte I/O page
to allow a little bit of extra memory, and this still works (albeit not
officially supported) under RT-11 (it was tested before the 5.7
release.)

The only paper tape reader I have right now is an ASR-33 and aside from it
being buried :), I can use it to read the tapes in. The PDP-8 was bought new
by someone here in Santa Barbara, and then donated to a local school which
is where I got it. It came with an ASR-33 (which I sold years ago <sigh>), a
Tri-Data tape recorder (anyone familiar with them?), and a schematic
package. One of these days, it would be fun to fire it up (hopefully not a
pun!)

You forget LE8, LP14, lp25 series of line printers. PDP-8s were used with
large and faster line printers of the day. Also the LA30 DECwriter was a
parallel interface at 30cps.
THey were far from limited to ASR33s (LT33).

Do you have any way of reading the tapes in? One way to tell is by reading
the comments. Another way is by checking the IOT's used for the printer I/O.
I myself cannot tell what printer those work with from the numeric portion of
the title, but I can say that just for parallel printers, OMNIBUS -8's
supported
the LA180, the LQP01 and LQP02. Common serial printers were the older members
of the DECWriter line (e.g., LA-36, probably not the LA-120). If that source
is for an older, non-OMNIBUS model, I wouldn't have a clue as to what model of
printer it would want to talk to. I think only the LA-36 was available in
current-loop configuration (excepting, of course, real TTY's).
Do you have a way of reading in the tape?

I made a curbside rescue of a dual ext. fdd. Two FH 5 1/4 floppies mounted
vertically. ZenithDS Heathkit H77 with ribbon cable connector. Looks more like
an 8" mechanism than your standard floppies. I'm assuming these were for a
Z-100 guaged by the ZDS H-K label timeframe . Any info on them ?
Judging by the mechanism that I can see , like Rainbow drives but not
laterly opposed , they're SS.

Nope, still working on getting them out. My dad is currently
sorting/separating cables. Be patient, everybody. (Paying the mortgage is
a little higher priority. 8^)
