Rescued a pair of Zenith Z-100s this weekend. Both an All-In-One
model and a Low-Profile model along with boxes of doc, parts and
software. They were sitting out in the garage of an old friend whom
I hadn't seen for years. When I told him I collected computers he
told me that he wouldn't pay me any more than $10 to haul them
off. :-) They're pretty dirty but otherwise seem to be in great shape.
These are cool little dual processor (8088/8085) S-100 systems.
Also picked up boxes of old software manuals and lots of old 5.25"
disks. Many are originals, others are just blanks.
The moral? Be sure and tell everyone you know about your
strange hobby, never know what might turn up.
Now, in the User Manual, they talk about CP/M-85. I've heard of
CP/M-80, CP/M-86 and CP/M-68K but not 85. I'd guess it is a
version specific to the 8085? Didn't know they made it. Anyone
know anything about it?

Now that's something I didn't think of. Thank you, that could have been
very embarrassing.
This particular MVII has a single RD54 and a TK50.
I don't have any docs, so can one of the decsperts confirm this please?

Work is continuing on my Exidy site. So far I've placed the
_Guided_Tour_ booklet which came with the Sorcerer as well as
the first 3 chapters of the _Standard_BASIC_ manual. The other
chapters will be following as I complete them. I've also placed
some PROM dumps sent to me by Pete Turnbull. He has also
sent some postscript and asm listings which I'll have up there
shortly. Lots more to go.

Have to agree, I have tried most everything from crappy freeware/shareware
to
ridiculously overpriced NFS/X/whatever suites. All suck somewhat, in
different ways.
If it's a windoze 3 or 95 attempt, the suction increases by orders of
magnitude.
Nothing beats a real DEC VT.

Hi there.
Can anybody tell me what the first external hard drive for a Macintosh was?
I am trying desperately to remember who made it and how much memory it had
and how much it cost. I remember that it was very big and very expensive.
Any insight would be tremendously appreciated...

< The best emulation for a vt I've found is decterm. Stands to reason, I

Procomm is pretty good. It's advantage is the parts I consider the most
broken are the keyboard and that configurable. I still use V1.0! I
consider the scripting language it's greatest asset.

Ran one for years with two RD54s, DEQNA, 13mb, DHV11, TK50 controller,
LPV11, RQDX3. The description is so you know it was a full box. Insure
the internal power cable is good and the ECOd one.

< Understood.
Vt100s do have line drawing character set, so if you had the right
translator... graphics. Vt125 however does have sixel mode (bit
graphics). Then again a vt340 does color and most of the DEC graphics
modes including Tek.

True to a point. Long story follows. A friend of mine was the manager
of the Terminal and printers QA group. They tested product to DEC STDs
and also previous products. IE: if a vt100 did it right or wrong they
knew it and the next generation would do that too in vt100 mode. VERY
FEW VT100 closed were better than 95% exact. None of the bugs they had
were subtle, others glaring. Vt100 was the most widely emulated, cloned
and flat out copied terminal made. It's easy to say that as there were
copies of vt100s, the vt220 also emulated vt100, the vt320, 330, 340 and
420 and a bunch of other along the way. then there were the clones of
each one those.
All one ever needed to do a good clone/emulation of vt100 is the user
manual and a vt100 or even better the technical manual. Worse yet the
ANSI terminal spec. Oh, the vt100 was one of the first ANSI terminals
that also did private escapes (dec private) correctly.

It's a very durable keyboard but it would still ruin it to no effect.
< Knowing VT100s, they'd probably work when they arrived ;-)
I've seen boxes that test that theory.
