If you boot it, you will probably find a copy of Apple System Profiler in
the Apple menu. That will tell you what you have installed.
The stock 630 series is actually a fairly useful machine. It used 72pin
SIMMS (FPM, but EDO work just fine), there is only one RAM slot, so it
will max out the machine at 36mb (32mb chip + 4 on board). The VRAM is
non upgradable.
As a stock machine, they are good workstations (pending you use non PPC
only software, since it is a 33mhz LC040.. the LC040 is a 68040 without
the FPU built into the chip).
I have a 630 running right now as a mail server, keeps up with everything
I give it no problems (runs Mac OS 8.1, with Stalker Internet Mail
Server... hosts a few domains and a few thousand emails a day, with a few
hundred accounts... never even hiccups).
The HD is IDE, which makes it cheap and easy to upgrade.
Other things of interest. It may have an ethernet card, but if you said
it came with a modem, I doubt it has ethernet (was the modem internal?
You could get an internal 14.4 geoport fax/modem in the Comm Slot... the
GeoPort modem is similar to those WinModems that use the processor to
handle all the modem functions, and the modem acts pretty much as an
AD/DA converter. HOWEVER, you may have one of the modems that was made by
global village... THOSE modems are real modems, and VERY VERY good, with
supurb fax software). If the modem is external, then you might have an
ethernet card in the Comm slot (look at the back for an RJ45 connector).
If you have a Global Village external modem (common performa modem), the
bronze (probably the one you have) is 2400 fax. It is a VERY good fax
modem, with excellent software... not so good of a regular modem (some
extension conflicts with the modem control software). There is also a
Gold version that was 28.8 fax... much better regular modem (newer
software, cured most of the extension conflicts)
Also, your docs indicate that it has the DOS card installed. However, the
630 didn't ship with a dos card... that was the 640 (upgraded version of
the 630, the 640 came stock with a DOS card... IIRC it was available for
the 630 as a 3rd party add in by Reply, so it may have been added). The
quickest way to tell if a dos card is installed is look at the back of
the machine. You will see an expansion slot. If there is a fairly densely
pinned DB connector in the expansion slot, you have a DOS card. There
should be a dongle cable for it that will connect between the DOS card,
and the Mac's video out. The cable will then provide a RGB connector, and
a Midi/Joystick connector. If you don't have that cable, the DOS card is
useless... good luck finding a replacement cable.
Finally, the 630 supports Video In/Out and a TV Tuner. Again, look at the
back of the machine, if you see RCA connectors for video, left and right
audio (Yellow, Red and White, RCAs), you have the video In/Out card. If
you ALSO see a RF Coax screw on connector, you have the TV Tuner... if
you have these... contact me, I would be interested in possibly
buying/trading them with you (I have a need for the TV Tuner card, but
will take them as a pair). If you have the TV Tuner card, you should also
have a remote control. It will either be a skinny black remote, or a
little credit card sized remote. Failure to have the remote will not
prevent the card from working, it just means you have to do all the
controls on the computer. (The Video Player software supports all the
remote functions directly, the remote was just a nicity).
What else... If the DOS card is not present, then the 630 has an LC PDS
slot, there are a few cards available for it (network, video,
accelerators, odds and ends). I think that is pretty much it. The 630
series is a very good 040 machine, and can still be used for a number of
things.

Actually, IIRC, it first appeared in the Apple IIgs shortly before
appearing in the Mac II, THEN in the SE... but I could be wrong

I was working for a small place many years ago that had recieved, by
Government contractor error, a 'classified' piece of radio gear stuck in a
truckload of other RF junk we bought. The Feds came storming in one
afternoon with the swat team (I am *not* making this up!!)
<snip>
-------------------------------------------------------------------------------
Speaking of classified equipment among the junk, that reminds me of a story at:

Novel twist on the car-in-the-side-of-the-mountain urban legend; a
little long, but I enjoyed it.

Speaking of CDC, among the junk I'm cleaning out of my basement there's a
partial backplane out
of an old CDC something-or-other, connected to a panel with 2 AC outlets
(Monitor & Data Set), a fuse and a DB25 for the Data Set. There's also an
acoustic delay line and a large resistor/diode
matrix board which I think came from the same piece. Maybe a 60's era
terminal???
3 rows of cards; the two top rows A & B have 25 slots for 4 1/2x6", double
sided 31 edge
connectors cards, some with 10 test points along the edge and each
populated with one or two
dozen gold 10 pin TO5 cans marked M (as in Motorola) 115, 116, 117, 118
with what I assume are
date codes like 6624, 6644, and 6636.
The bottom row, C, 32 slots, contains a few smaller cards with pin
connectors that appear to be
some kind of programming cards, just containing jumper wires.
Anybody recognize these and maybe even have a use for a card or two, or can
I throw them out
without feeling guilty?
mike
If they do, I'm not aware of it. This may be the case, though.

I _think_ there are video problems with both units. They seem to attempt to
boot up, while leaving the monitor in a relatively empty state.

Hi again. :)
I just thought of another question. I have in my possession four TRS-80
model IVs. Two portables, (one working, one not), and two desktops (one
working, one not).
The desktop will run in Model III emulation mode. The portable will turn on
and ask for a disk.
Anybody know where I can find some operating system(s) for them?
I'm also thinking about taking the ram from the non-working machines, and
using it to max out the memory in the working ones. Good idea, bad idea?
Regards,
Chris

In most cases you can type <ctrl>Z when it asks for the date and time.
Unless they were clever in the startup routines)
The you are logged in as [200,200]
SET /DEF [1,54] the "normal" system account.
Then your able to totally corrupt anything you want. Suggestion: DO NOT do
anything but read files in [0,0] They are the equivalent of the MFT.
You should find in [1,2] plain text help files for almost anything you
should happen to want to do.
I could help more if you had posted the version of RSX and whether it is M+
plain M or 11S. I doubt it is 11S as there it is uncommon.
When it comes to the older core memory UNIBUS systems - good luck. I lost a
couple in the fire and the hobby market has gone crazy for them over the
last couple years. I do know of a few still in commercial use that may
eventually be replaced but they are dual processor shared memory and
peripheral configurations that really complicates their replacement.
Dan - Going back to check on the RSX11M+ SYSGEN I started for a customer
when I started to catch up on the list.

Little 3 pronged thingy icon... thats ADB... plug the keyboard in there,
chain the mouse thru the keyboard (you'll find the same connector on the
keyboard) 4 pin mini din should only be ADB on a Mac... at least in terms
of "stock" connectors.
