I have a small handful of these parts with a Motorola 'M' on them.
They are 3-legged, seeming to be a transistor or similar device (I
don't think they are voltage regulators). The case is plastic,
smaller than a 78M05 (T220?), especially since the metal thermal
transfer patch is integral to the body (not sticking up above the
epoxy like on a 78M05).
The markings are...
R927
S
AC823
I can't seem to find anything reasonable by googling Motorola and
either R927 or AC823. Does this sound familiar to anyone here?
Thanks,

I have an IBM XT with all original parts. This is the middle era
version with a Xebec/IBM harddrive controller (no dip switches),
newer diskette drive, and an IBM 20 MB hard drive. The computer
boots with no errors. It looks like the computer was never used,
it's pristine. Might anyone have a link to a program that I can
use to run a low level format specific to this controller card and
hard drive? I have had trouble locating the low level format program
via DEBUG. I have found a number of Debug commands on the Internet
for other drives and controllers, but none for this. I have searched
the segement offsets between C000:0000 and EC00:0000 in 0400 increments.
.Maybe I am blind! Is there an IBM official low level format diskette
image out there? That would be preferred.
Thanks...Bill

wow, that's super cool! I always thought the SX64 was one of the coolest
things that I have ever seen, and it was way ahead of its' time. I gotta
laugh on the box where it says "business or office"... beacuse, um, that
40 columns sure makes spreadsheets a pain.
if someone would like it, I am going to be dis-engaging myself from it -
$100.00 plus shipping and it's yours.

There's no guarantee it's an Apple 1. The seller says only he can see
"wires and cards" inside. Perhaps it is an Apple ][ in a wooden case?
Nobody knows, and without pictures, nobody will know.
My take is that the seller knows full well what it is, and is hoping
people will think it is an Apple 1 (and judging by the questions at
the bottom, they do). People will then drive up the price to some
outrageous level. When they get it and realize it's just a //e that
someone threw in a wooden case (or maybe not even anything in the
Apple line), they'll get mad, but there's nothing they can do because
he described it accurately .....
Cynical, yes, but most likely true :-)

John Bohner got it.. I know he's a big fan of the G-15 and friends.

I'll have to put the pics up for it, it was REALLY nice, full
docs, and software. Hopefully I can get copies from John at
some point.

Hi Ethan
Jameco list them, using the AMD number AM27S19.
The are suppose to be the same but most likely
program a little different. Most data i/o 19's can
handle them with the unipack.
I've had good luck with Jameco on PROMs but
I've had bad luck on RAMs. They gladly replace
them with some more U-TEST-UMs ( 2114's ).
Later

Hi,
Does anyone know the voltage requirements are for the ethernet
transiever on these parts? Is it 12V or is it 5V? The specs do not
mention this. I know that the Coral HPT02 uses 5V and the IMSB407 also
uses 5V, but what about the IMSB300 and/or IMSB431?
Note that the IMSB300 actually contains an IMSB431 Ethernet TRAM
underneath the hood..
I have an idle IMSB300 which I want to start using...
Thanks,
Ram
