I just passing this along, can anyone help him repair his drives?

Dave, I have an entire Cromemco Z2D system that I purchased at an
auction several years ago. It was completely disassembled, and was
noted as 'computer junk' and sold as a lot. Assembled, it had two
monitors, two 5-1/4 drives, two 8" (wood cabinet) drives and many
extra S100 cards. There's an analog-digital IO card, 3 64K mem, 6 16K
mem, Dazzler (still new and unassembled), set of joysticks, and other
misc hardware. Although I'm not interested in selling it (it WAS my
first computer after all), but I sure could use some help finding
someone to repair one of the paired 8 inch PerSci drives.

I completely missed this. Thanks for pointing it out.

Yes. There are two banks of memory on the 9100B, + and -.

Yes they are.

It's on the quick-ref card. This works as I expected. If I want to
go back or go to an absolute location, I have to switch to RUN mode
and do a GOTO from there, then switch back to PROGRAM mode.

Howdy,
I am fooling with a 9100B calculator that used to be on exhibit, I'm
guessing in the electronics museum that used to be at Foothill College.
Toward that end it was hacked: a plexiglas strip was screwed to it
above the switches, with cutouts for the switch handles that only let
you move the power switch -- program/run, fixed/floating, and
degrees/radians were all stuck on run, fixed, radians respectively.
Well, I've removed that because I want to find out what if any
programs were in its memory (core remembers things long after they're
better forgotten), and so I want to flip the program/run switch over
to PROGRAM. But I'm a little confused about the 9100's program mode,
and unfortunately I don't have the manuals handy.
When I flip the switch to PROGRAM, the display changes to what I am
guessing is this:
<step> <instruction>
<Y mantissa> <Y exponent>
<X mantissa> <X exponent>
<step> seems to be represented as <hex digit>.<hex digit>. True?
(And does this mean there are only 256 program steps?)
Are <instruction> values 00-09 the keypad switches 0-9, and others in
<column><row> form? And if so, where's <0><0> for the <column><row>
form?
Can I use the STEP PRGM key to single-step forward non-destructively
in program mode? How can I move backward, or to a given location in
program mode?
Can y'all tell I'm spoiled rotten from having learned programmable
calculators about 15 years later?

About how fast is a DECsystem-ten compared to a Pentium or something?
A friend and I got into a "whose computer is faster" fight.
I have the 11/23, he has a Vaxserver 3100. I have the 44, he has his
Pentium/something.(133 or 150?). I have a shell into a DEC-10, does that
beat him, or do I lose? (I think it does, does anyone have the numbers?)
If any is a DOS disk, there was a post recently...
bcumming(a)mail.island.net
wants DOS 3.2 or might be interested in some disks.

Normally, 486 motherboards are set entirely in the CMOS setup program.
Jumpers, etc. typically control speed and processor type. Are you having
trouble getting it to come up?

Today I place the new version of the CCC online. Now listing 3806
computers.
In this revision I have set up the infra structure to link each system
to its own page. The intent is to provide information and links for each
system. See the entry for the Sperry SPEEDAC computer.
BTW anyone heard of the ULTRAMAC computer built in the mid fifties?

I have added it to my web site, based on a) being obsolete, b) being a new
concept for its time (first MS-DOS palmtop?), and, of course, c) being
really keen.
Anyway, 1989 is even starting to get old in computing terms.

Found on Usenet, can anyone help out?
