Today I set out to debug my other (previously donated/defective)
16K core board in order to have a full 32K in my 8/A. The board
was completely dead (0000 at all locations). A quick test program
to read all locations in field 4-7 and a little scope work (it's
handy to have a current probe) showed that one of the two
paralleled X Read/Write drive transistors was defective and so
that stack current pulse was only half amplitude. After replacing
the transistor, powering back up and booting OS/8 from my RL02, a
MEM command now showed "32K MEMORY!" :)
Everything pretty much seems to be working just like before (such
as LUNAR in PFOCAL, and various BASIC programs). But when I
attempt to run ADVENT I get the following bizarre error messages:
DIVIDE BY 0 ID("IL 0000
DIVIDE BY 0 ID("IL 0000
DIVIDE BY 0 ID:SIL 0357
DIVIDE BY 0 IE\/IM 0000
BAD ARG IE\/IM 0000
ID:SIL 0357
IANBII 0000
IEG8IM 0000
IEH?IM 0000
IE BIM 7240
IAVBII 0000
and then it either returns to the dot prompt or crashes.
This disk image works perfectly (including ADVENT) on my laptop
running SIMH.
This looks to me like part of a file is corrupted (the presumed
garbles are repeatable), but I don't know which one... any
thoughts? I haven't run a test pattern on the "new" core board and
wonder if it could be the source of this error. Rick M. are you
out there? ;)
thanks for any help.

All the below applies to NS 3.3, don't recall for earlier versions
(none of which are recommended, with some minor caveats)
One of the "Dock" icons should be a clock/calendar (or some subset
thereof). Double-click that, and it'll bring up "localization
preferences". Click on the mouse, and you can change the mouse speed.
People always comment on how fast my mouse is...
As others have said, if a "me" password is set, you get the login
screen. If not, it logs you straight in as "me", which is not a
recommended way to run the machine (but if you've got boxed versions,
you can always rebuild the HD...)
To set the password, go back to Localization Preferences, and click
on the padlock.
To create other accounts, I always use UserManager (found in the
NextAdmin folder).

All,
spotted in the San Antonio Goodwill Computerworks:
A Mac 512k, but with a minor difference. On the back side,
above where the power switch normally is and far away from the rest
of the connectors, is a 25-pin D connector reminscent of the Mac
"SCSI" connectors on Mac Plus and other machines. I did not
disassemble or power up the machine (no KB or Mouse in evidence), so
I don't know what it is.
Don't know whether they'll pak/n/ship. They were asking $5
for the machine. No connection. Let me know (off list for quicker
response) if you want me to go back for it and work on boxes and
postage for you.
Forgotten what the correct designation for those D-connectors
is, and wanted to get this out fast in case anyone wants it.

Well I would call it a data logger.
Some DPM (Digital Panel Meters) have RS232 (or 458 balanced line)
outputs.
They can be set for one output per second. Just capture and store.

I managed a buyout of genuine DEC H8571-J MMJ adapters awhile back and
just got them in. They are brand new and are in factory sealed DEC
packaging. I'm planning to list some on eBay and VCM, but I thought I'd
post an offer to the list first. They are $25.00 each + postage and I can
ship internationally. I also have about a dozen of the H8571-J work-alike
adapter+cable kits that I've been building for $20.00 each, but I'll
probably make some more once those are gone since they have been extremely
popular.

I bought several eBay lots of floppies, one of which purported to be
cromix discs. It appears only one was a cromix disc, the rest appear
to be cdos. I haven't looked at them in detail. About half of them
have been read and are up under
http://bitsavers.org/bits/Cromemco/floppy
There are also what appear to be UCSD Pascal I.5 discs for CP/M up
under
http://bitsavers.org/bits/UCSD_Pascal/cpm
I know nothing about AIX or it's associated hardware
(oh ok I know it's made by IBM). I know little more
about HP-UX. All I know is I want a box/boxes I can
run this stuph on. This is a continual plea and the
cry of my heart :(. I know there's some of this stuph
out there for me. Question is how do I get it. Thus I
turn to y'all. Please help. Please...
