My serial number project is going slowly. I only received two responses (thanks, Charlie
and Joe) and so my sample set has a woeful three date points:13352 (Charlie's), 13513
(mine, sold 1/77) and 14213 (Joe's, sold 9/77). Perhaps a rate of about 1000 units
per year in 1977, but too little info to tell. If this rate is correct, I would suspect
the the numbering began around 12000 or so.
C'mon everybody, have a look at the back of your 5100 (the number is engraved into the
back of the case, usually preceeded by a "10-") and keep those numbers coming.
Thanks.

Mine is a Basic machine and has serial number 15041. The serial number was
on a tag located on the bottom of the machine, and I didn't see any dates.

#12206. I win.
You will have to wait for the 5103s number.

Actually mine is on a metal plate on the bottom of the machine.

New subject: IBM 5100 Serial Number Project (and a question or two)
I just received a 5110 (BASIC-only, no tape drive) with serial number 30163.
I've got a couple of quick questions for the experts.
First off, I think I may be getting an error on startup. When I power the
system up, the display shows
AACCEEGG
on the top line. After five seconds,
AACCEEGGJJLLNN
RRSS44
is displayed on the top two lines. One second later,
AACCEEGGJJLLNN
RRSS11
is displayed on the top two lines. After three seconds, the top two lines
are erased and
LLAA00
_ _ (two flashing underscores)
EEDD
is displayed on the last three lines of the display.
Actually, when the display switch is set to "64", the above strings appear
on both the left side and center of the screen.
Is this some sort of error display? Does anyone have any sort of error
summary for the 5110? The "Process Check" light remains dark. Hitting the
keys produces no result.
Second question: what's the BNC connector on the back of the system for? I
read somewhere that the 5110 and 5120 had composite video output, but I'm
not sure.

When I do a "reset" on mine, I see "ABCDEFG" at the top left of the
CRT.
on the top line. After five seconds,
AACCEEGGJJLLNN
RRSS44
shortly after the "ABCDEFG", "ROS 01" appears, which gets replaced by
"ROS 02", ..., "ROS 09", "ROS 0a", ... (not sure about the
leading 0, but it
appears to be a ROM selftest, counting up in hex).
is displayed on the top two lines. After three
seconds, the top two lines
are erased and
LLAA00
_ _ (two flashing underscores)
EEDD
Mine says "LOAD0",
then "__" (I think),
then " READY" (with some leading blanks)
BTW, "Inverse" switch is pressed towards top of case (so I get white on
black background), the L32/64/R32 switch is in the middle (64) position
(which means: display 64 chars per line)
Actually, when the display switch is set to
"64", the above strings appear
on both the left side and center of the screen.
Aha...sounds like a video problem. What shows for L32 switch position?
(You should see: L O A D 0 and " R E A D Y" (note the blank between
each character!)

New subject: TRW 8/28, socal meeting
Sorry to use list bandwidth, but what a week, and time is short.
I won't be able to make it to TRW this month (yeah I know, more for all of
you). Worse some kind of a SoCal meeting fizzled, ie 4 people responded,
and I haven't even followed up on them. I barely have time to type this
out, but I will be fussing around my garage after about 2 PM on Saturday,
maybe Sunday, with trusty portable phone (714-771-7509). Also unfortunate I
was unable to pry another 386 computer keyboard thing from the salvage
joint (the new tech loves it and is upgrading them to 486 with bigger
drives etc.).
