520ST does indeed run GEM; it's about equivalent to a Mac Plus or so. 512K
RAM, (unless expanded) 68000 CPU. What it does have that other machines in
the same class (early Mac's, early Amigas) don't have is built-in MIDI
ports for connecting to musical keyboards and synthesizers.
That's what I (would) use in my studio (if I had it all set up) for
composition and sequencing. (Doncha just hate moving?)
The 800XL is an updated version of the venerable 800. Has BASIC built-in
and only one cartridge. Nice machine.
Today I saw an Atari 5?0ST and an 800XL. As I understand, the ST ran
GEM. Is this an interesting computer at all? What about the XL? Was
this one of the BASIC computers?

Well, I don't necessarily see anything wrong with once in a while
destroying a useless piece of junk, like a PC or a C64 (despite
popular belief, third world countries will _not_ be better off with
more computers). In general, moderated violence is vital in society,
so that unmoderated violence is not as common. Singing and dancing
is good too, but remember that Cain is the one who was a vegetarian.
Of course, I have no idea why people showing off technology would
want to do it by smashing stuff. Ah, that's life...

I thought the only difference between the logic boards was the
PROMs/PALs. Of course, not owning a Lisa, I can't be sure about this,
alas...

This is what I've heard, too. In fact, one of the newer Lisa gizmos sold by Dafax is a "ROM switcher" so you can use both the original Lisa H-roms and the modification 3A-roms without further tinkering. (I guess you'd just put up with oval circles and whatnot in Mac apps, since the ROM switcher doesn't do squat about changing the video.) All these repair manuals say "hang onto your old ROMS so you can run Lisa stuff in the future" which seems to indicate that it's feasible to revert the change. ???

varies. There are generally two styles of cards dual width (AB) and quad
width (ABCD) and two styles of backplane those that are bussed with the
same signals on AB/CD pairs and those that are bussed on the AB side and
the CD has a unique bussing for user configs and special use.

Just for accuracy sake, they fling using a trebuchet (sp?), not a catapult.

Have a Memorex Telex model B7000000 286 machine in a slim line case and
a 3.5" floppy on a riser and a
Quantum Prodrive 40S hard drive. As per the usual, the setup is
botched and the hard disk is not recognized. I
have the usual generic setup utilities but am hesitant on doingt
hat since the 40S is an SCSI drive. Does anyone
know if this machine is a software setup or keystroke started CMOS
and where to get the setup program or what
the keystroke(s) are. This is getting set up to help a
homeschooling single mom out here and it would suit her need
fine once I can access the setup.

I don't have this issue, but the Dec. 71 index shows for the November '71 issue:
"An electronic desk calculator you can build", by Roberts, page 27.
Later in the Oct. -Dec. 1974 issues he had a digital logic course with a low
cost terminal- 3 octal digits.
In the 1974 Electronic Experimenter's Handbook, there was a 6/9/12 digit
hand-held calculator by Lorinda Russell amd Bill Yates of MITS. I don't know
what P.E. issue this is from. This issue also had 2 articles by Harry
Garland and Roger Melen, including the "Muscle Whistler". I still have one.
Later Cromemco had a similar relation with P.E. For example, in the Feb.
1976 issue was the "TV Dazzler" article.

If you dig a bit further back in the issues you find it as a project.
logic analyser is far more than it was.
