Except for MV3100's (he explicitly says no to them), this fellow's
willing to pay real money for a cheap VAXen.
If you can help, reply to him directly. Thanks.

I will be in Western Washington State next week (6/16 to 6/22) on
business (American Chemical Society regional meeting in the
Tri-Cities).
Is there anyone in the Spokane-Walla Walla-Yakima triangle with a
small VAX to donate or sell ($200 or less)? No MV3100's, please.

At 5$ it's interesting to have as a spare assuming the shipping isn't
over 20$.

<>VGA display.
I should elaborate. I'm looking for a mono (or color) display that is
very low power and size is not that important other than I need to be
able to see 80charx24line text on it. Graphics are not required. While
some CRTs can be under 10watts power my desire is an order of magnitude
lower if possible. An LCD would be ideal but alas none are available
(low cost) that have more than the basic LCD drivers. The DELL laptop
LCD I have is typical of the MONO 640x480 displays and the "video" input
is not like a crt in timing or signals. For example the display is
really two 640x240 running in parallel with seperate video for each.
Hand built logic to do that costs enough in power and design time to
make it unappealing or no better than a good mono crt unless I resort
to Gals/FPGAs (design effort and cost prohibitive for a one up).

I have started bringing home the expanded Apple II+. It has an
external "Executive Peripheral Systems, Inc." keyboard, with program
macro modules for Wordstar and Visicalc (great keyboard,if only it
clicked), and the regular DuoDisk. I also brought home the DR CP/M
card manual. The Apple II and floppies will be brought home next week.
I was firstly thinking of putting this into a PC case, since the
keyboard is external anyway. But I was reading the CP/M manual
(pretty shallow), and it mentions a 16-user capability and password
protection. How does this work and how secure is it? Also, would you
say that the Z-80 was better than the 8088? It was certainly used
much more...

Someone had e-mailed me the pinouts for the AST PenExec (aka GRiD
Convertable), but I lost them when my e-mail crashed. Whoever it was,
could you be so kind as to resend them? Thanks!
Also, the GRiD version was available with a 386 (2260) and 486 (2270).
Does anyone know if there were also two AST versions?
Thanks!

Because if I use a baby AT case, it will take less space than the
apple case. I will also be able to stick the floppy drive inside.

The CP/M 3+ manual says the syntax is drive:12345678.123;password.
Maybe it's a weird DR thing. They tended to add weird stuff...

OK, so it seems to be the last CDC machine, after the Cyber 180s. Does
anyone have any information on these things? Any still in use?

Well the 16 user thing is not multiuser it's a way of diving up the
directory into 16 distinct areas as CP/M didn't have subdirectories.
Password protection? There wasn't any as part of CP/M.

Better... that's a relative term. It was cheaper to use, more software
available as it was fully upward compatable with the 8080 (and 8085)
that preceeded it and it was there before the 8088. Also as the 8088
got faster the z80 also got faster and added a MMU. I can still build
a system using z80 for less than the 8088 and the z80 one will be easier
to program. If the program gets larger than fits in the 64k space then
the competition becomes a bit more fair. Still segmented space is pretty
ugly and a paged MMU on z80 is very easy to do. Or better yet a z180
(64180) which is a z180 with MMU, 2 serial ports and a DMA all on one
chip (and still cheaper and faster than a bare 8088 in 1985). The z180
also offered something the 8088 line never had which was a compatable
highly integrated version as the 8088 needed several parts around it to
use effectively and the '188 was an odd duck compared to the 8088. So
for the 8088 comparison the z80 was hard to dislodge. It really took the
386(32bits) to make a real impact.
Z80 space was characterized as developing, it was inexpensive to develop
around, there were lots of similar and competing systems (both
a blessing and curse), tons of cheap to free software, offered sufficient
compute power and friendy to program in assembler. The only other chip
to be as persistant, easy to use and popular was the 6502.
I might add that both were quite popular in the instrumentation and
control sytems field.
Tidbit... the z80/z180 is still in production and the cmos z80s182 runs
at a screaming 20mhz internal clock (roughly 2-4mips processing speed)
and can come to a complete stop, using only microwatts of power in that
mode. I have a z180 at 9.8mhz and it's quite fast for text apps and is
usually waiting on the SCSI hard disk system (xybec/st251).

The "16 user" isn't really a multi-user capability. Unlike MS-DOS,
Unix, VMS, etc., CP/M did not have subdirectories. The main directory
was it, everything fit there. This was not so convenient, so "user
areas" came into being with CP/M v2. The 16 users are actually numbered
subdirectories. The "C> USER 5" command would switch you to
subdirectory 5, equivalent to a "C> CD \DIR5" in DOS. The idea was if
multiple people used the machine, each would have their own area. On V3
the user 0 area was a common directory, I think there were some commands
to control this (very rusty on CP/M V3). I don't think CP/M V3 was ever
implemented on the Apple card, since V3 was designed to use banked
memory over 64K.
As for 8088 vs. Z80, I would rate the 8088 as one step above the Z80.
It was slower, but had a larger instruction set and a crude MMU built
in, out to the 1MB limit so familiar today. The Z80 was a bit faster at
the same clock rate, and the 8088 never got to a very high speed, IIRC
it got to about 8 or 10Mhz in the Intel version, NEC sold variants out
to 12Mhz. The Z80H was an 8Mhz part, it kept up with the 4.77Mhz
original IBM quite well, except for the memory limitation.
BTW, on S-100 systems the 8086 was far more common than the 8088, since
the S-100 could support a real 16-bit bus.
Zilog and Hitachi eventually extended the Z80 out to 512K and then 1MB
with an MMU too, but it was never as flexible as the segment registers
in the 8088.
As far as design difficulty, using an 8088 or Z80 was about equal. The
8088 had a minimal mode for small designs, or support chipset for
expanded systems. The Z80 took some random logic for the clock signal
and needed some type of MMU if you needed more than 64K.
