Here are some photos I took of my tempest Macintosh. There's nothing
particularly extraordinary about this machine unless you look at the
details.
I didn't get any photos of the inside because this thing is a total bitch
to take apart. It took me about half an hour just to get the back cover
off when I first cracked it open. It's not because of the hex screws or
anything like that. This thing has a metal housing built into the case,
with a bunch of finely machined screws holding everything together. To
take the back cover off requires undoing more than just the standard hex
screws. The nubs on the I/O connectors also have to be removed.
Anyway...
Back side of the unit. Note the toggle switch which replaces the old
on/off switch. The knob below it is a fuse holder. Note the power cord
is now permanently attached to the unit. The back I/O connector panel has
been cutout and then re-attached with new cutouts to reduce the holes
where emissions could escape. This panel is laced with a metal mesh. A
CRT brightness control has been added to the left of the battery holder
(the battery cover is missing). The small cover screwed into the case on
the left side is where the slot for the security device used to be.

Front of the machine. Nothing unusual except for the square slot cutout
where the keyboard RJ14 connector used to be. A close-up view is coming
up to show how the keyboard attaches.

Side view. Guess what? That slot is another Sony 3.5" floppy that has
been installed internally. The slot has been manually cutout.

The backside label enlarged so you can read it. The manufacturer (or
rather re-manufacturer) is Systematics General Corporation of Sterling,
Virginia (a wholly owned subsidiary of Atlantic Research Corporation). I
mentioned this on the list when I first got this unit sometime in 1997
I believe (or early in 1998). I paid $10 for it.

A close-up of the keyboard connector. It attaches to the unit via the
modular plug. Then the panel screws on to the front of the machine. The
duct tape looking piece of material is a metallic mesh that prevents
leakage of emissions. Note the brass gasket attaching the shielded cable
to the keyboard housing. The metal box on the back covers the old
keyboard connector.

An update on the Wang system I rescued from Certain Death.. I
found a good portion of the manuals today while on an un-related
mission to the warehouse. I was walking past 2-story-high pallet
racks full of boxes of paper files, and a Wang binder caught my
eye.. sure enough, what appears to be the operations documentation,
including much custom work by the sysop(s) was in an open box. I
now have it with the machine itself.
Anyone on (or off) the List who is interested in acquiring this
taken-out-of-service 7110 system... contact me via e-mail. It
seriously wants a loving home and some 220-1 ph to eat.

Well, it just goes to prove once again that not all of the rocks have been
turned over.
Based on a recent tip from another collector, I've managed to knock one
more item off of the Computer Garage 'Most Wanted' list with the arrival of
an IMSAI dual floppy disk sub-system.
No software or docs with it, but that just adds to the adventure! B^}
Something about the unit suggests that the previous owner ran CP/M on it,
but as to just what that clue is I will leave without explaination. (that
way you have to look at the pictures) <G>
The images are immediately post-unpacking, so the unit has not been
cleaned, checked out, or powered up... but its here!!!
Hmmm... I wonder if there is a copy of IMSDOS buried around here
somewhere??? <BG>
And hopefully (if Murphy does not interfere) by the end of the weekend yet
another item will be struck from the list! Stay Tuned!!

I'm about to have an abundance of H89 systems (among others) and wonder if
others are interested some light hearted swapping.

Hi Jeff,
>You want some advice, eh? Okay. These beasties support
>CGA or EGA (you set this up from the setup screen...
Thanks, at least I know now not to fry an MDA monitor checking this out.... ;-)
>....and AFAIK, I'm pretty sure they support 1mb simms. (the
>later models had VGA, and supported more memory).
That would make sense, wasn't the '286 limited to a total of 4Mb physical RAM
(unless you added EMS)?
>....worked fin for most MS-DOS appz.
Yep, the fact that they're '286 based isn't a problem to me. I just want to use
them under DOS for running stuff like TurboBASIC etc.
>How do you make it boot? Ha. You have to have either: 3Com
>3+Start server software, or 3+Open Start (for OS/2 LanMan)....
Hmm, I was contemplating setting up OS/2 Warp on one of my machines....don't
have LanManager though. :-(
>I think I still have all of this stuff somewhere, ifn you
>want it....
I'll contact you off the list about this.
>....The only problem is, you'll need to dedicate a PeeCee
>just to run the boot services (and whatever other network
>services you want)....
Well, I was thinking about having a play with networking....one of the reasons
I dug the 3Com units out. :-)

every IBM machine with a bios date of 1996 or later will automagically roll
over to the next century. Previous machines will simply have to have the date
command invoked to set the century. I set the date on my PCjr and it accepted
01-01-2000 no problem.

Every brand of computer has a Y2K section on their website, best to refer
to that for specific information.
The only systems I am familiar with are several of the old 486 compaq's I
have include a SIIG extended bios card that is supposed to make them Y2K
compliant, and the IBM PS/2 model 95 have a bios patch for some units. >>
Have a sealed copy of Lotus Appraoch 2.0 Database for Windows....and no
use for it. It says it has both 5.25" (1.2mb) and 3.5" (1.44mb) disks.
It states 286 or higher, Win 3.0 or higher, hard disk, EGA or better
video, mouse, 2 mb RAM minimum.. It says it's compatible with files from
dBase III & IV, Paradox, FoxPro, Oracle SQL 6.0 and SQL Server databases
in native format.. It also states that's it's network compatible with
Noverll Netware and Netware Lite, MS Lan Manager, Banyan VINES and
LANtastic networks. Allows grpaihics imports in BMP, TIFF, PCX, WMF and
EPS.
$5.00 plus whatever the postage would be and it's yours. Drop me a
direct note if interested.
Hi
A while back, I had to come up with a clock system that
would work with a simple clock chip that only went up to months
but not years. The machine did have some other non-volitile
memory so here is how I delt with it.
I had what I called a half year counter. If when the machine turned
on, the clock chip thought it was in early half of the year
and the RAM said it was in the last half, I'd update the year
and reset the bit. The only requirement here was that the
machine had to be turned on at least once every 6 months
or soemone had to reset the time.
Why they couldn't have done something as simple as this for
the century, I don't know.

The term CRACKER is as old a the railroads, if not much
older than that: it was used in the 1800's (and to some
degree, this usage remains today) to refer to those
persons with a nack for entering a safe without permission!
Forget your history, and you are doomed to relive it!
