I noticed there's now both an stc directory (with the 2920 manual) and
a storagetek directory (with 4220 and 4280 manuals). Are they not the
same company? The stc manual says 'storagetek' at least once inside
(although it mostly uses the term 'Storage Technology Corporation',
and one of the storagetek manuals for the 4220 (which has 'StorageTek'
on every page) uses 'Storage Technology Corporation' on its address
(last) page. Maybe it's easier to find this way, if the emphasis
changed from 'STC' to 'StorageTek' over the years, is that why? Or are
they really different companies?

Yes, STC or "Storage Technology Corporation" was the earlier name.
Generally, if there are name changes I use the earliest name but I 
didn't have any STC docs uploaded. I'll merge the two at some point.

I'm working on scans from about six other STC products right now.

To be pedantic, M4 Data / STC / StorageTek should all be under "Oracle"
since Sun bought StorageTek, and DEC/Compaq should be under whatever 
"HP" is calling themselves this week, so I try to stick with the 
earliest company names.

Fritz,
It turns out that I was missing the KJ11 my cpu cards were wired to
expect.  On the 11/40 this module is the little M7237 card for space E of
slot 3.

The machine in question  did not come with this card, I assumed it was not
needed until I checked the cpu jumpers and discovered my error.  Should
have done this 1st!

It was impossible to run the CQKC diagnostic for 11/40 or 11/45 -

This may be a pointless question, but just to clear the ground first: the CPU
is otherwise functioning reasonably well? E.g. it's not dropping the 020 bit
when reading words from memory? (That would convert the '220' new PC in the
vector to '200', and produce exactly the behaviour you are seeing.)

If it is otherwise more or less working, so this is specific to IOT trap
handling, I agree with Fritz - a KM11 would be a big help.

It was not apparently dropping the 020 bit.  The problem was a missing
KJ11, I did not notice the CPU cards were wired for one.  When I first got
this 11/40 10 years ago it did not come with it installed, I *assumed* the
machine as I got it was complete.  My error.  Lesson: Always check
everything.

Ah. Well, if you want to add one (I assume you've just re-jumpered the
machine for the moment), I do have one we can copy (for the PC etch) - I'm
assuming here that originals are now unobtainium.

Also, if you have the KE11-E, but not the KE11-F (the former is a prereq for
the latter), and would like one, I have one I have no use for (Unix doesn't
use that version of the PDP-11 floating point), and would be willing to trade
it for something I do have a use for.

> My error. Lesson: Always check everything.

Yes, always a good rule when dealing with recovered machines. I always take
them apart and go through them completely, verifying all cables, etc from the
original documentation.

Actually I had one, put it in, fixed problem. i.e. I kept the jumpers
as-is, added the KJ11, system now works better in that I can load BASIC,
diagnostics, etc.  Does not mean the system is perfect though, but I have
been able to move to the next point in the troubleshooting process - Goal
to boot RT-11 from an RL02.

re-initialize PDP 11 BASIC?

[william degnan]

I seem to remember there is an entry point that one can use to reinitialize
BASIC already loaded into core memory, with the intention of re-answering
the questions about MEMORY SIZE, Use SIN?, etc.  Is this correct?  I looked
in the docs I have b ut I could not find it.  If no one has this info I
will have to disassemble, IN a HEX editor I see the questions are all at
the end.

Re: Tandy TRS0-Model 2000 Computer Monitor required

[Sam O'nella]

The 2000 isn't fully compatible either i thought since its one of the few PCs 
using the 80186 processor. When i acquired mine (also without a monitor and i 
think without keyboard or software ) i sort of accepted id likely not get it 
running. But perhaps the  software is out  there and less of a concern than i 
thought.

I didn't know it was compatible with the cm-1 but i never checked what video 
card mine had.

Still an interesting system historically.

Building replacement panels for machines

My classic/vintage computer activity has taken a back seat lately but I did
find a machine I had on the "classic" list for some time.  It's now part of
the collection.
http://www.classic-computers.org.nz/collection/imac.htm

Some would say this is not vintage, classic or collectible (and so
shouldn't be discussed here).  However, these are all subjected terms which
can be (and are!) argued about at length.

To me it's a noteworthy model which had some impact on personal computing
(notably by helping put Apple back in the game).  Vintage?  At only 18
years old perhaps not but a classic and collectible?  As time goes by I
would say yes.
