If this is on an S-100 System (and if we're talking about 8"
drives, as opposed to the very rare 8' ones :), you can try
connecting the +24V line to the unregulated +18V.
>From the installation instructions for the Quintec Tophat, a
dual 8" (TM848 Tandon) drive assembly that fits across the top of
a Cromemco Z-2:
...Using a good DC voltmeter be certain that the +18V line is running
at least 18 volts, preferably higher, around 19 volts...
And if anyone really needs a +24V supply, I *might* have one or
two in the basement somewhere (+5, +12, +24). Not light, though,
as I recall...

Nah, that's for Kryptonite bike locks :-)

Hi
It sounds like you have the wrong sector size.
It might also be that the disk are actually single density
and not double. It sounds like it is reading the first
sector ok. You might check the parameters for that format.

HP 98155As are very rare. He is lucky to have one.
Best thing to do is to use the keyboard from a Series 80
computer (the matrix is the same).

Hi
That is interesting. I just went to a local small shop
locksmith with the lock from one of my machines and
he created two keys for it at $15. He didn't even have
an original key to work from, just the lock.

I've slowly been working through the box of carts that came with the
ISI system that
I just picked up from Erik Klein, but there doesn't appear to be a
complete binary
distribution tape set in the pile. An image or physical cart of a
version from '88 or later
(4.x or 5.x) would be helpful in trying to get the system going again.
Just to get it saved on line somewhere, the format of the cartridges is
a little tricky in
that ISI tape controllers simulate variable blocking on QIC cartridges
by appending
512 bytes of data in front of the actual data blocks. The first few
bytes are all that
matter
for example:
A1FE 0001 0002 2800 0014
is a magic number, file number, block number, and block length (10240
bytes)

Web forums are not friendly to some browsers. They're also slow. Mail
delivery is indeed push, not pull; by the time it gets to local
delivery reading is just opening a local file, which is rather
different than downloading a page on a server at the same time as
umpteen other people. And it's a damned sight easier to search, sort
and filter a mailbox (local, or IMAP) than a web page.
I'm with Cameron, Sellam, and Jules. And probably a few other people
who wouldn't want to use web technology because they have to be online
at the time they are reading, all the time they're reading. Not
friendly to dialup users.

I think this is totally unfair and unacceptable. This means that if a mail
server is having even a slightest bit of downtime (hardware failure, scheduled
maintenance, whatever) that lasts more than 35 min, then all users of that
mail server lose their mail?!

Hi
The board did exist. It was there to support the software
for the M20. It was suppose to be able to run the PCOS software.
I wonder how low a level the CP/M-8000 got? It might
be able to be run on the M24 as well, with the board.
I've seen pictures of the board so I know they did make them.
