Having now looked "inside," I find that there's no Intel coprocessor, though
the
doc's suggest that there should be one, so the mezzanine board has apparently
been removed. The modems are Global Village types, thoguh I don't know what the
baud rate capability is. There's a connector on the back, which I'm sure is
"stock," that has an indicator on the back of the box suggesting it's a
network
connector of some sort. It's a 4-pin mini-DIN. There are no add-on cards of
any sort inside, though there's a clearly-marked connector for the video-in
board. The SIMMs are 4 MB, i.e. they have 8 1Mx4 DRAMs on board. With a
half-GB HDD, which was "stock" with the '630, I've got to say this was
a
MINIMALLY equipped computer, though the popular functions all seem to be there.
I'm not at all certain how they (Apple) got all that functionality out of the
clearly limited resources. That was their trick for keeping costs low, however.
It makes it hard to understand why the got rid of their CEO at about that time
(/94-94), since he seemingly presided over the generation of this and similarly
high-profit machines. The stockholders should have loved that.
These were released in early '95, and the typical PC of the time had at least
twice the hard disk space and, typically, 16 or 32 MB of RAM, and I do believe
the typical PC of the time had a larger (14") monitor, yet overall system cost
was about 20% less than this model.
I'm just guessing, of course, but that's the way I seem to remember the MAC/PC
price/equipment comparison. I had routine contact with numerous MAC users back
then, in the form of teachers at my kids' middle/high schools, where I was on
several different committees and humg around the school to snoop on them quite a
bit.

Subject: Re: OT: paging MAC expert(s) --- What's a Performa?
The
documentation that came with this machine implies it's already
equipped with
the DX2/66. Is there some sort of utility in the system that would make
it easy
to see what the thing perceives itself as having?
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.
