Lisa Tank Problem
blusnowkitty:
Well I found the VSROM that came with my Lisa when I bought it and I've tossed it up in my list. I never noticed until just now but I noticed that there's a "location code" encoded in the VSROM serial. Think that corresponds with the California and Texas plants?
I think I finally have enough data to speculate that at peak, at the A plant anyway, they could produce between 500 to 700 systems a day - I've got enough systems from the 415x date range now to make that guess. There may also be enough data in the 333x ranges to make an educated guess too. This sheet also seems to indicate that AppleNet numbers seem to not be quite as sequential as we thought since it sure looks like to me that both factories produced systems where
Day 1, 1000 systems made with Applenet 00101000 - 00101999
Day 2, 1000 systems made with Applenet 00106000 - 00106999
Day 3, 1000 systems made with Applenet 00102000 - 00102999
and so on and so on.

Which part is that again? Visible in Service Mode? Sticker on the ROM? Part of the SN?
Edit: oh right: p78: http://mirrors.apple2.org.za/ftp.apple.asimov.net/documentation/applelisa/AppleLisa%20-%20Good%20Things%20to%20Know.pdfand https://www.applefritter.com/content/apple-lisa-serial-number-info
--- Code: --- First remove every other nibble like this:
00000240 0F0F 0002 0802 0002 0000 0400 0300 0F0F
240 F F 0 2 8 2 0 2 0 0 4 0 3 0 F F
Then group the numbers as follows:
Number of the Nibble in Hex 01 23 45 678 9ABC D EF
Address 240 FF 02 82 020 0403 0 FF
XX PP YY DDD SSSS X XX
Extract the serial number from this group of 16 nibbles as follows:
a. Ignore nibbles 0,1,D,E and F, marked as XX or X above.
b. Nibbles 2 and 3 are the two digit plant code (PP).
c. Nibbles 4 and 5 are the two digit year code (YY).
d. Nibbles 6, 7 and 8 are the day of the year code (DDD).
e. Nibbles 9 thru C are the 4 digit serial number (SSSS).
The Applenet Number is similarly embedded in the first 8 bytes of the next
line of the memory dump. So, using the same method as step 4 above, we get:
00000250 0000 0100 0004 0102 0002 0900 0000 0000
250 0 0 1 0 0 4 1 2 0 2 9 0 0 0 0 0
Number of the Nibble in Hex
012 34567 89ABCDEF
Address 250 001 00412 02900000
PPP NNNNN XXXXXXXX
7. To extract the Applenet Number:
a. Ignore nibbles 8 through F, marked as XXXXXXXX above.
b. Nibbles 0, 1 and 2 are the AppleNet prefix (PPP).
c. Nibbles 3 thru 7 are the AppleNet number (NNNNN).

So then that would imply the ceiling is actually under 10K? Maybe 8K units instead of 13K?

Here's the SN of the System Source Muesum's Lisa 1 I got to help work on this weekend:
https://twitter.com/compu_85/status/1414245531212304396/photo/1
It has no sn sticker.

Awesome! Thank you! Best of luck repairing it.

More photos of AppleNet number 33 here: http://www.macgeek.org/museum/applelisa1/
I was also thinking about the manf date in the System Source Lisa 1's VSROM... 82380. Aren't there only 365 days in a year :o
