OK to fair. ;) It was file level password protection and required the
whole colume to be enabled for it. Security level was low though. If the
user could assemble and run a program they could write code to access the
disk directory and toggle the right bits and they had control. It was
aimed at captive applications where the user had limited resources and
could not get directly at the file system. Many of the things in CPM3
are there to provice more direct compatability with MP/M.
As to weird, no most of the additions they did were similar to the ZCPR
groups and other were doing in parallel and had sound basis.

good luck finding the software as it was never PD and alloy controllers
where never that common that I've seen.

<I rescued a Digital WT/78 word terminal with a Digital RX02 computer
<attached.
Ok, the WT78 is one of DECs early compact word processing systems. The
CPU is the intersil 6100 (PDP-8 reduced to a chip). The RX02 is nto
acomputer but a disk box and controller for 256k/512k 8" floppies.
(others in that family are the DECmate, DECmateII and DECmateIII)
< It does try to boot, but I don't have the system disk. I'd sure love
<to see the beast run.
The images for the disks(both WPS and OS/78) are on the net and you would
need a system that can create 8" disks. Alternately someone that has
a system with RX02 disks (they were used on PDP-8, PDP-11 systems).
< What does it run? What kind of processors does it use? It has network
<and modem connections.
The primary processor that runs the OS is a varient of the PDP-8 family
reduced to a single chip. The disk system has it's own processor but
that is not user programmable.
It _does_not_ have network connections. The idea of a network at that
time was unrealistic for such a low end machine. The modem connection
however is eaxactly that and could be used to connect the machine to a
host for file transfers.
<How do you use those, and what were they originally for?
It was originally used for word processing running WPS78, it also runs
OS/78 an older PDP-8 operating system that looks a tiny bit like DOS.

<Ooh! Does anyone have a relevant Hitachi data book?
My assessment is that for the display I have to convert serial video (VGA)
to two 4 bit parallel streams for a partitioned display is unrealistic.
The next simpler option if to generate video directly in the form required
for the display and that is also somewhat ponderous. I didn't see
anyhting suitable on the Hitachi site.

Password protection? There wasn't any as part of CP/M.
<The CP/M 3+ manual says the syntax is drive:12345678.123;password.

You didn't say CPM3! If you say CPM it is assumed the more common v2.x
version. V2.x did not have passwords, V3.0 did. Obviously if this apple
cpm card has V3 disks it it was a very late one or someone went to some
trouble to port v3 to it. FYI: v3 was not widely popular.

Perhaps list subscribers who wish to list their items on an auction
service could offer a discount to other subscribers (e.g. "Mention you
saw this add on the Classic Computers mailing list and get 10% off.").
This way the seller gets the higher prices of the auction services while
at the same time offering an advantage to list subscribers.

I have acquired the manuals, S100 controller, and cartridge tape
drive, but not the software, for an Alloy Engineering cartridge tape
drive. I have two manuals, the Interface Guide For the IDXS-100, and
TIP (Tape Interchange Package) Operator's Guide, both dated 1981. The
tape drive is an early 3M cartridge tape, capacity of about 14MB
formatted. I also have a big box of backup tape cartridges.
This system came from a multi-user Concurrent CP/M 80286 system in the
early 80's. The system disk was pulled from the S-100 box when it was
retired, and the original floppies are long gone. I figure if I can
find either a Z80 or 8086 version of the TIP program I can get the
system directory off the backup tapes.
Does anyone know more about these tape drives? A binary of the TIP
program?

Cirrus Logic made LCD controllers that would drive an LCD and also an
external monitor. I have an older Compal TS-38 laptop with the chip,
driving a dual scan color LCD, but with a switch to go to an external
monitor.
I've seen Him/Them Beign flamed about it on some newsgroup (pretty funny
too), other than that Have no idea.
