Joe,
I don't have DosPlus for the Model IV that I know of
(I might, somewhere..). But, I can recommend highly
Multidos for the Model IV.
I don't have the link handy, but if you search for it,
you can find it.
It's still availble for purchase in the $30.00 range
last time I checked, and it is an Alternate OS for the
TRS-80 that incorporates a lot of the strong points of
DosPlus, including 80 Column support while in non CP/M
mode.
It's a nice OS, and the DISK BASIC is faster and
smaller and more feature rich than most of the other
ones available for the TRS-80.
I remember porting my Copy of Connection-80 over to it
(we renamed our custom version, Nybbles-80), and it
was MUCH faster under Multidos than under Newdos/80,
TRS-DOS or DosPlus, and I was able to take advantage
of several MultiBASIC features to make it nicer...
Boy, those were the days.
I'm on the lookout for an LNW-80 Computer that works
to set up a system again. I'm going to keep watch in
April at the Trenton Computer Festival for a Model IV
or Model III in the Flea Market.
Regards,
Al
I would like to do a bad sector scan on a RD52 connected to a RQDX1
controller (The machine is a pdp11/73 without OS) prior to installing
BSD2.11.Is there a standalone program like zrqch0(standalone version of
zrqc from the xxdp package - only for RQDX3) that can be downloaded
directly to the pdp via vtserver and recognizes the RQDX1 , i.e. a version
of zrqb or something similar?
Aw, come on, Joe! Enlighten the guy!
(I know too)

hi Folks...
i have an IBM PowerStation 530 free to a good home in the UK (Cheshire) if
anyone is interested in it.
It appears to be non-working... it powers up, but the status indicator seems
to show it's not booting properly. I dont have a monitor or keyboard to test
it.
I saved it from the skip about 18 months ago with the idea of resurecting
it, but the lack of manuals & software make it pretty hard.

if anyone is interested in it, drop me an email... if not it's heading for
the bin!
thanks

Not me. My 4.3BSD suffix is Quasijarus, not Tahoe or Reno. But my opinion on
SHAC is radically different from yours. SHAC is a darling beauty. It is a
problem only for cheap OSes like NutBSD and Linsux. Since SHAC is a true CI
host adapter with the true Generic VAX Port (GVP) it is perfectly supported by
the SCA CI port driver present in every proper VAX OS with SCA such as Ultrix.
Although DEC killed VAX Ultrix before MicroVAXen with SHAC came about, source
examination shows that the Ultrix V4.20 CI port driver supports SHAC (on XMI).
Some day I will lift the SCA code wholesale from Ultrix and plop it into
4.3BSD-Quasijarus.

I was contacted by a chap who spotted on my page that I had a 4/470, and
wanted to know did I want another one...
Unfortunately there's no way in heck I can afford to ship one from
California to Iowa, so I'm passing it onto you fine folks to take it off
his hands... His wife says to get rid of it, he's already tried to donate
it to a local college and even a surplus store, with no takers.
He lives in Salinas, CA, which is near Monterey, but he commutes evenings
to Santa Clara.
He can be contacted here:

Tony Duell beat me to this when he wrote:
"There have been many devices which implemented the IEEE-488 bus (GPIB,
HPIB) using a standard parallel interface chip like the 6821 or 6522
together with buffers."
My Osborne 1 (Z80, 64K, CP/M, 5 1/4 floppies, tan case, '82) labeled their parallel port "IEEE-488" (aka HP-IB) and wrote low level routines for the eight basic HP-IB commands into the bios. They used a 6821 PIA to drive the port, an interesting mixing of chip families. My computer whiz high school son and I built some software around their stuff and I used the Osborne (personal) at work (DOD R&D) for several years to talk to, among other stuff, Nicolet digital scopes. I don't remember much about the details and don't know whether I can find anything useful, or readable, on the software, but the bios routines should be available in the Osborne tech literature. I still have the Oborne, but haven't tried to run it for several years, will have to see if it still lights.
My next laptop was a Toshiba T1200 (80C86, 1MB, 3.5 floppies only, MSDOS, '89) which had a bidirectional parallel port implemented in a custom gate array with eight additional control signals. I remember that we tried to do a klunge to run '488 on that but can't for the life of me remember whether we were ever successful. I'll have to dig around some more in the old stuff and see what I can find.
Good luck on the project Vassilis.

Frank -
I found an old post at
http://www.classiccmp.org/pipermail/cctech/2002-July/000309.html
You list a VR201-C PRO monitor.
My neighbor (& landlord) runs a tractor repair business. He's an old
farmer who doesn't like to change much, and has been using the same DEC
inventory system since 1986. For 16 years, he's maintained a service
contract, but now that DEC was bought by Compaq, and Compaq has merged
with HP, he's facing an $800 annual bill for a service contract which
has only been used to replace burnt out monitors and printers (2 of each
in 16 years)
The monitor includes a 15-pin connector, which I'll gues is db-15, and
an RJ-11 keyboard jack.
Does your monitor include these connectors?
Would it work on a DEC Unix system?
If so, do you still have it and how much would it be to ship it to NJ -
08825?
Thanks

I heard tons of opinions being spewed,
not a fact in the bunch....followed by
genuine shock that not everyone has the
same opinions.
My opinion is that the best way to stop
this dribble is to put the whole cctalk
list on digest. That would make it much
harder to carry on an argument.
