DQ686 is an ESDI controller, with MSCP protocol. Don's right, do not
connect ST506/412 drives to it or you'll release soe magic smoke!

I have a Newton.. also the complete, never-used programming kit.. And a
spare LCD should anyone need one...

MTI MSV05 = emulates DEC TSV05.. I have the manual for it... I think its a a
QIC controller, not sure off the top of my head..

Yesterday (and into the night), I powered up one of the two 11/44
machines rescued from San Diego. Did the usual thing of taking out the
cards, documenting cables, cleaning, dusting, and then turning things up
slow and watching voltages - no worries, the systaem came up and was
subsequently reassembled in it's as-acquired config.
It boots from two Micropolis 51/4" half-height drives sitting in the
card bay of a card-less 11/23 chassis... which has been re-badged by
Centaur Software. The front panel switches control write-protect, now.
I don't have models right now, since I didn't work on that device yet.
But they connect to a Dilog DU686 controller card - a quad-height card
with one common 34-pin ribbon and individual 20-pin ribbons going to each
(of 2 drives). This is... MFM, no? the original owner called them SCSI
but somehow I think not.... Anybody have Doc on this Dilog card?
The machine currently runs RSX-11M V4.2 G Build 58, or so it says. File
creations run from 1980 to 1997, when the machine was shut down. The
physical devices are mostly from '79 to '83.
It has Fortran, Basic, and Oregon Pascal V2 installed.
There is an RL02 system, working nicely, and couple of multi-line EIA
muxes, one DEC (M7819) DZ11 and a Ditronics 16-line EIA mux.
There is also a Digital Pathways SLC-1 real-time clock/calendar that
sits in the Console line and responds to certain interrogatories from the
System... fairly funky, IMHO.
It came with printsets for all major subsystems, and the Blue Wall, and
about 20 RL02 packs, most of which are blank.
If everything goes as planned, I will bring this machine to VCF5.0 and
let it be Played With.
And, looking back into the Files, it was Bill Bradford who first brought
this machine to the attention of Chris Kennedy, who referred it to me, and
voila! here it is warming my (pleasantly) chilly garage while we wait to
see if Autumn is going to actually stay for a while. It was pushing 90
here this afternoon... wierd! Should be fixing to snow....
So - now to wake up the Second System. Since this was a
mission-critical machine, there are actually two complete
identically-configured 11/44a and disk subsystems. The RL02 is shared by
changing cables to the machine in use, and the TTY lines are all hooked up
to a bank of DPDT mini switches (also by Centaurus Software) so that, if
one system crashes, the other can be cut over by changing one connector
and flipping the switches.
Anyway - not a particularly 'rare' or 'significant' system, but
certainly fun to mess around with. It certainly gets stares from my
nieghbors. One of the local kids looked in while it was running this
evening and asked "what's *that* thing?". I told him it was a computer.
"No Way!!"
Cheers

7th Edition certainly runs on QBus. That's what one of my 11/23's is
running, and it was a development machine for Heriot-Watt University, when
they were the UK distribution centre. It has 256KB RAM and two RL02's on
an RLV11 controller. With a small tweak, 7th Edition will also run on an
11/73.

Went to a large school auction Saturday and got lots of stuff real cheap.
There was hundreds of computers stuff at this auction. I got;
Epson PX-8 missing keyboard cover and ac adapter.
2 - IBM EduQuest Fifty-cs desktop computers that work fine, first time I had
seen these. I have several of the all-in-one units.
IBM type 3194 controller.
NEC MultiSync 6FGp 20" monitor for $1 and it works great.
Apple IIe platinum case and 6 external 51/4 floppy drives.
IBM Thinkpad 350c no charger but only cost $1
Compaq Contura 3/25c no charger but also was only $1
And I got about 15 P166 Compaq for less than $1 each along with one P266
Compaq, several IBM 486's desktop all for less than $1 each. There were some
Dell's in the lot also.
Also got a box full of game consoles that I have not checked yet but saw a
Genesis 16-bit and NES on top.
Went to unload the van at the warehouse and stopped at a couple of stores
and found these hp items:
hp 82162A Thermal Printer with one roll of paper.
hp 82169A HP-IL/HP-IB Interface unit.
A plastic bag hanging on the junk rack with a hp ac adapter 82059D; hp
82160A HP-IL module; and three different length hp cables for the above
units.
Also picked up a power supply for the Zenith Supersport 286 notebook.
Just purchased a digital Prioris HX 5133DP server at a auction and it is
password protected. It powers up ok and then ask for the admin password.
Does anyone know a work around to get into this system? Can put a new
version of NT 4 on top of it? I do have a legal CD that I got last year that
could install on top if I will not lose the drivers that are already on the
machine. Thanks in advance for any help.
