Well, I've opened drives in room air and had them run after, but it does
make it less reliable. It's a thing like ESD: if you want to risk it.

Well, the cpu on this mac is socketed, i *could* just pop it out- in fact it
resembles an intel type chip very much. that's what really piqued my
interest.

There's also the program 'SoftFPU' (or something like that) which
emulates an FPU. Slow, but it works.

My first thought for the 2 BNCs would be a Stereo SID (sound chip)
modification. That is a popular hardware mod that adds a second SID
sythesizer chip to the 64 so you can have 2 channel, 6 voice stereo. There
are a few music writer programs and players and a game or two that support it.
Usually the mod has RCA type jacks though...
Pretty cool if you like the 64 sound output (which is really good for an 8-bitter).

Hi,
Great day today, I found:
Zenith ZT1, aparently it is a phone terminal and has the manual to connect
to compuserve. Is it also useable as a computer? I have the manual but it's
burried at the moment.
HP 97 brand new in the box and it seems to be working fine. I'm charging the
battery right now to check it. Standard pack and business decision pack plus
a bag of programming sheets
Text editing, math, Visicalc Plus and owners manuals for the HP85
HP thermal printer with HPIL interface (HP 82162A) what is that for? is it
tfor the HP 75?
HP82901M Dual 5.25" flexible disk drive with HPIB interface. I believe it is
for the HP85
Box of five blank tapes for the HP 85
HP110 laptop computer (8086 or so) with MS-DOS 2.0 in ROM With manual and
lotus 123 complete.
2 HP9114 3.5" disk drives for the HP 110 with manual charger and HPIL cables
HP 2225A Think jet with HPIL interface for the HP 110
On the sad side I had to pass on an Original MAC M0001, a MAC SE, SE/30 the
HP 85 (already have 2) a box of thermal paper for the HP85, a commodore
calculator and loads of softwares for the HP 85 and 150 series and a bunch
of unrecognized boxes (probably compatibles) I'm really thinking about going
back tomorrow If I can get the OK from above:)

As I told Tony Duell a day or two ago, I would list the modules residing in
my 11/730. Point being to compare machines for completeness/options and to
get feedback from list members to learn more about what both of us have
exactly.
I would like to fully restore this machine to it's original completeness
although not necessarily its original options/configuration. I'm missing
front/rear doors, some hardware, a few modules, misc. items and the
all-important TU58 tape which has the bootup microcode(!). Hopefully a
fellow who responded privately can find some docs and cabinet parts that he
might have which will help for sure. I'll be looking for the rest though.
The main problem I have found with the module list is that there are no
references in the Field Guide for these particular 11/730 modules. Maybe
because the Guide was for *only* Q-bus and UNIBUS modules and these don't
fall into that classification *or* simply the info for these modules was
not at hand when the FG was put together. I'm working on that now with a
fellow who emailed me in reference to a more up-to-date FG. Any input from
the group is welcome of course.
Here's the list of modules, in order of slot number, in the 730 as I
received it:
1. empty
2. empty
3. empty
4. M8390 (-B?)
5. empty
6. M8391 MCT
7. M8394
8. M8750-CP
9. M8750-CP
10. M8396
11. M8396
12. G7273
13. G7273
14. empty
No expansion backplane is installed presently. I think it may have been
taken out as there is reference on the module list printed on the CPU cover
which shows a 9-slot DD11-DK Unibus Expander Backplane installed in the
left side of the crate.
I have not dug into either of the BA11 crates I have in the pile yet but
would the 9-slot expansion backplanes in these actually be the DD11-DK? Is
"DD11-DK" marked anywhere on them?
The Ethernet cable is also hanging loose in the crate. Either a single
board Ethernet I/F was in slot 14 or the 2-board DEUNA or equivalent was in
two slotts of the DD11-DK expansion.
For the sake of comparison with what the factory-original module compliment
says, I will note in quotes ("") what's on the CPU cover label:
1. "Not used"
2. "M8389 FPA (Option)" (must be a floating pt. adaptor)
3. "Not used"
4. "M8390 DAP"
5. "Not used"
6. "M8391-YA or M8391 MCT"
7. "M8394 WCS"
8. "MS730-CA"
9. "MS730-CA"
10. "G7273/Memory"
11. "G7273/Not for Unibus Option"
12. "G7273/Not for Unibus Option"
13. "G7273/Unibus Option"
14. "M9202" (and) "G7273/Unibus Option"
<end 11/730-A CPU listing>
<begin DD11-DK backplane listing>
1. "M9202" (bridge from slot 14, above) "G727"
2. "G727"
| | (all 9 slots have G727's listed)
| |
9. "M9302" (and) "G727"
Hmmm, if I either have a DD11-DK in a BA11 or something around here or if I
could find one amongst list members, then I could hang Unibus options off
this machine :) Cool!
Anyway, my guess is that I don't have too far to go to restore this box
with help from folks here. Tony would benefit too regarding his own 730.
And yes, I understand it is a true dog as to performance. But it was
mentioned by Allison correctly that at least this is a "real iron" VAX
which will fit in a room and power requirements are low enough to be rather
tolerable. Recall I have a space problem here. I saw a picture and weight
(1k+ lbs) of a 11/780. The wife would shoot me if I had one to keep out of
that truckload <g>.
Thanks again for the help. Regards,
--Chris

In looking at the RK07 and RL01/02 drives that I have from the Great Haul,
the connectors and cables look rather similar.
In the 11/34A I am keeping, there is a five-board set which is the RK611
controller. The previous owner had RK07's hung off this controller. I want
to use at least one RL02 in the system as most of the disk packs with the
important s/w are RL01/02. Anybody know if the RLs will work off the RK611
controller? (This is one of those dumb newbie questions!)
If it won't work, anybody have a spare RL11 controller module (M7762)
they'll let go? There's a heap of RL's (7) in the stuff I got but the only
machine in the whole pile that has an RL11 is the 11/24 which is not going
to be kept by me.
What would the cable run limits be on either the RL11 or RK611 systems?
As someone had told me a bit earlier about SDI systems, only ODD number of
cables must be used. Any such limitation here?
Thanks for your input!

I finally went back to check on that "Wang PC-002" I asked about earlier.
It was a bit more scratched up, but it hadn't moved an inch in the past
two and a half(?) weeks.
I managed to locate its keyboard, as well as the keyboard for an aparently
keyboardless Tandy 1000TX that was in another part of the building, so I
decided to drag the Wang machine home.
NOT an easy job. It was about a mile to the nearest subway station, with
lots of broken escalators up and down once I got into the system. And I
was carrying a large book bag full of stuff I have to look over for work.
By the time the bus dropped me off near home, we were in the middle of a
thunder storm. So I left the computer on top of someone's gate post (wide
brick thing with flat cement top) under some trees near the bus stop, and
made a run for home (about a half-mile).
I went back with the car as soon as I got home.
Anyway, it sure is a curious beast. And HUGE, to my eyes. It's not quite
as big as I reported before, but it's BIG. The closest offhand and
possibly innacurate comparison I could make is to a friend's MicroVax, but
I don't know what kind of MicroVax that is.
If I sit it vertically (a position the box looks very comfortable in), it
measures about 15" high, by 6.5" wide, by 23" long.
It has two floppy drives mounted in the front: one half-height 5.25"
drive, and one full-hieght 5.25" drive.
In the back, I can see the backs of various cards. One of them has the
connector for the keyboard (4-pin DIN) as well as one serial and one
parallel port, so it must be the motherboard. Beside that (or above,
depending on orientation) is a board with a sticker reading "PM032-B 512K
Memory Expansion". Next to that, is what appears to be an empty slot, and
then there is what appears to be some kind of networking card. It has two
coaxial cable connectors and a toggle switch. There is another card
beside (or above) that, with no ports or labels, but I can see chips
through the air holes. Beside (or above) the mystery card is a board with
a label reading "PM101 IBM Mono Emulation". It has an 8-pin DIN connector
and a 5-pin DIN connector, which I would guess are for monitor and PC
keyboard(?).
Does anyone know the pinouts of the various ports, or anything else about
this machine? Will it read PC disks or do I need to boot it up with some
wacky Wang-format disk? Does the machine require some kind of terminal,
or will a monitor connect into the back of the IBM Emulation board and let
me see what's going on?
The sticker on the side (top) of the machine says it's a PC-002, but the
sticker on the back says it's a PC-P002.
The keyboard has a lot of word processing functions on it.
Anyway, I haven't opened it up yet, or done anything with it but look at
it. Disassembly looks like it might be difficult, because I have to slip
the innards through the full length metal sleeve. I won't be up to that
until my arms recover. I've even got bruises and some kind of blood
blisters or something, from carrying that thing. :/
I probably won't have time to play with it today as I promised to install
NetBSD 1.3.2 and some UNIX software on my Amiga 3000 instead of coming to
work. (And look at the time. :) )
