Hi,
I'm looking for a copy (scanned or otherwise) of the Microtan 65
mainboard schematic and a copy of the Microtan 65 parts list. I'm planning
to adapt the video circuitry to a 6502-based computer I'm currently
building.
Thanks.

Doesn't make sense to put it in the 22-bit backplane if the processor
and memory can't use it... The backplane you have is fine...

Fine... an 11/23 (KDF11-A) will work there as well... and if you don't
have that or can't get it, the 11/2 is fine to get the machine going.

Okay, it isn't DEC... and is ESDI... great... you have disks (do you
have a floppy to attach to it so that you can install software?)
The DECNA is for the PRO series of machines... you need a DEQNA or
DELQA... since you are going to be running PDP-11 OSes, the DEQNA
should be fine if you can get one. If you can't, you will still
have a workable machine.

Yes, you can replace the M8044-B with an M8044-C (for 16kw) or
M8044-D (for 32kw). The above parts are fine, but you still need
a boot board (REV-11) and a serial line unit (DLV11 or, better,
a DLV11-J). If you can find an MXV11-B, you can add its memory
to that of the M8044-B you already have and get up to 24kw plus
two serial lines and boot code which will boot from MSCP type
disks (as well as code for DX, DY, and DL).

I've stumbled across a PDP-11/70 in VA (+1 540 area code).
It has a tape associated with it. I'm not sure how much
they want, but I believe that I'll be getting some 11/70's
closer to home (which are already spoken for :-)).
I currently have a person who is #1 on the list for the system,
and his #1 priority expires on Monday. I'm looking for a #2
person to give the system to (if my #1 doesn't want it).
Any takers?
Also, anyone have any PDP stuff they're getting rid of (perhaps
the novelty has worn off?) :-)
Cheers,
-RK

I've got some FREE STUFF in Austin, Texas.
Only thing is, you *HAVE* to pick it up, *IN PERSON*.
I"m tired of people saying they'll arrange something,
have someone come by, etc.
Its up for grabs for the first person who shows up and can actually put
this stuff to use, or emails me with a *convincing* reason why I should
hold/ship it for them and has something to trade for what they want.
First batch, some Sun VME boards and a 4/6x0 memory board:
http://www.mrbill.net/~mrbill/freestuff/ (pictures)
(the DELNI and the GRiD laptops are spoken for)
Some of the cards are FDDI:
http://www.mrbill.net/~mrbill/fddi/ (pictures)
Second, a Toshiba T3100 orange-plasma-screen laptop. CMOS battery is
dead, but it works fine if you have a DOS boot disk and put the time in
manually. Makes a GREAT serial console for a *NIX machine:
http://www.mrbill.net/~mrbill/laptop/ (pictures)
(well, its more of a "portable"; it only takes AC power and is rather
heavy.. if you've seen "Medicine Man" with Sean Connery, one of these is the
machine he's using in his "lab" IIRC...)
Third, I have a pair of IBM P70 portable (486?) systems with orange
plasma displays. When I got these, one powered up but gave a "bad HD"
error code, one didnt power up at all. I attempted to swap out the hard
drives between the two, but after I tried that, neither would power up.
I beleive they are both missing the back system cover, but would be great
for replacement parts to keep another P70 running.
Fourth, I have an IBM PC Convertible laptop, with dual 720K floppy drives,
LCD screen (of course), battery pack, and the I/O-port "pack", in original
IBM canvas carry case. Last time I fired it up (early '99?) the backlight
was intermittent, but otherwise everything worked fine. Great keyboard; might
make a good serial console for something.
Again, free, but you must pick these up in Austin, TX, at my house.
I will NOT ship anything (unless you have a REALLY good trade offer,
and pay for shipping). If you want something held, you will have to
trade me something interesting for what you want.
I'm tired of people telling me "oh, I'll pick those up soon" or
"I'll have $relative who lives near there contact you", etc.
First come, first serve. I need this stuff out of the way, but its
too good to trash..

I've got a TI Silent 700 portable thermal printing terminal (has 300 baud
modem, acoustic coupler cups, etc)... but this isnt just *any* Silent
700 (model 765):
This has the bubble memory expansion (which from what I understand, is
rather rare).
On a sticker inside the paper compartment:
DATA ACCESS SYSTEMS, INC - HOUSTON
Servide 713-682-6820 Sales 713-682-5965
Model # TI 765
Serial # 04766-17603
DASI OPTION VENDOR
1B07 80 K. MEM
KIT II
1B10 (CHAR MAP.)
Last time I fired this up a couple of years ago, it worked, although the
thermal print head either needed cleaning or replacing - a pin was "missing"
in some of the output. I didnt have time, at the time, to take it apart
and clean it or diagnose the problem.
Has the "snap-on-top" cover with carrying handle, etc. Cover was the
victim of some slight paint overspray (white) when we painted part of
this room, but no paint got on the unit itself. The cover only got
slightly dusted on one corner; it may come off with rubbing alcohol.
Would like to swap for something else interesting. I had two of these
(the other didnt have all the spiffy options), and gave the other away
a year or so ago... I just dont have room for this anymore, and would
like to see it go to a good home.

If you're talking assembled and working boards, you probably want to put
them in static-dissipative (primary) packaging and put that in antistatic
(secondary) packaging that's capable of protecting them mechanically. The
totes aren't all they're cracked up to be unless you have a way of sealing
them. The "nickel" bags as primary packaging with pink-poly
(non-static-generating) secondary packaging to protect them from physical
trauma and the whole thing in a sturdy box together with other similarly
packaged and protected boards should do the trick. A little dessicant to
prevent condensation inside the primary packaging is helpful as well.

I've got an embeded syatem based around an LSI-11/2 processor board,
M8044-BB (8KW?) memory, pair of DRV-11's, a MDB eprom board and ADC board.
What do I need to do to make this into a functional PDP-11? I've got a
DEC MSCP ESDI controller (don't remeber the part #), DLV-11 (8-port
version) serial card, TQK50, and drives from my VAXstation 3200 I can try
to use in it. It's from my DPE 5000, the video part of which let out a
bunch of magic smoke being powered on - can't find any obvious burned
parts, but haven't checked the power supply yet. Still, it's worth more
to me as a LSI(PDP)-11 than a video effects box that I can't fix.
First, however, I'm sure I need DEC boot roms for it, or some other way to
get boot code into it. Does anyone happen to have some laying around they
could maybe send me an image of? Also, I'm on the lookout for a RLV12 and
berg cable to connect to the RL02 I have sitting around here..
Any ideas/help would be appreciated, and thanks in advance.

Does anyone have any knowledge of a machine put out by Industrial Data
Terminals back in the '80s that was called the IDT Screenmax System. It
was a non-standard unit that utilized a hard drive, single 5" floppy,
and bubble memory to be a custom video design package. The unit in
question was used to create industrial process control screens.
IDT was taken over by Cutler Hammer Automation and when the unit failed
in service recently it was returned to them for repair. They replaced
the hard drive, did not install CP/M-86 to make it bootable, and
proceeded to lose the master diskettes that they had requested be sent
with the unit.
