Hi
Sure sounds like a thermal limit switch. It could also
be a Poly-Fuse.
As for voltage of the transformer, if it is bad, one can
still determine the ratio by cutting the wires off with
a single cut per turn and then count the wires for the
primary and secondary. One does have to watch out if there
are taps, other than center tap.

Yes, I'm a bit confused...

A basic 11/24 processor uses 22-bit addressing but a Unibus uses 18-bit
addressing and therefore can address up to 256KB; the top four bits of
address are therefore dropped by the MMU in a basic 11/24. If it's
fitted with a Unibus Map (KT24, M7134, which also replaces the M9312
bootstrap card) then an 11/24 can use 22-bit addressing, on an extended
Unibus, giving it a 4MB address space. It does this by feeding the
output of the MMU through 31 mapping registers which provide
relocation, so at any given moment you can actually only address 31
pages, each of 4KW (8KB), plus the I/O page; you need to re-program the
mapping registers or the MMU to access the whole 22-bit range.
I don't know where the 1MB limit comes from, that would be a 20-bit
address range.

Yes, that should work.

Hello all,
does anybody know, how much memory the 11/24 can take ?
I heard something about 1 MB, others say 4 MB somewhere on the web. Yes, I'm a bit confused...
Currently, it's configured with 1 MB.
Furthermore, does a DELUA - Card properly work in it ?
There's only the card, the bulkhead assembly is missing, I would have to build it by myself...

Howdy all,
I have two Macs, a Mac IIsi and 7200, I would like to get rid of. Does
anyone have any recommendation for a Mac collectors group that might
have some individuals interested in these machines? Listings for these
machines on both Ebay and Vintage Marketplace have yeilded no takers.
Thanks,
-- Michael

That shouldn't happen unless the Keyboard Interface PCA is strapped for
"compatibility mode." Open the unit, pull the Keyboard PCA, and check the
DIP switches at the top of the card. Switches P and Q should be set to 0
(closed) for normal operation.
With both closed, the terminal should power up in alpha text mode. Then it
may be switched to graphics text via an escape sequence or by the keyboard
TEXT key, as desired.
(I have an HP 2647A. P and/or Q are set to emulate a Textronix graphics
terminal.)

I just recently got an HP25. I like it this much (1E99++).
I am putting together an applications pack of sorts that I will
be able to make available as a PDF. I have 4 programs so far,
Do any of you have/use the HP25 calculator? Do you have an
HP25 programs you'd like to see in print?
Send programs off list: ron.hudson at sbcglobal dot net
All programs will be added. I have the HP25 applications
book, let's not duplicate anything there.

Yes, I did more digging and found a web site specializing in vintage
calculators, and it had a full discussion on the different types of
displays... and yes, it does appear that I have Vacuum Fluorescent
Display Tubes. This was reaffirmed with a closer inspection (with the aid
of a flashlight) and each of the segments appears to be an individual
tube (you can see the curves of the front as well as the typical peaked
top).
I've yet to open it to see if they are socketed or soldered... I figured
I'd leave that until I new more about the technology and if the tubes are
repairable, or if I can get the correct replacement part.
