Yup.
These are mine from the chassis:
SN: A3334150, AppleNet: 00108643, MFG: 3334 - recent buy, last year off ebay, this had Jazz on the Widget drive and is a 2/10.
SN: B08B831460139, AppleNet: 00104391, MFG: 83146
Missing sticker, I think this was a lease, has two stickers, top one has a red border and black numbers, no bar code, in a white box says: "Property of Apple Computer Inc." A1081 and then a 2nd one, black box with a barcode: 106336 - not sure what these mean, but the 2nd one looks like an AppleNet and possibly the top one is the S/N.
SN: A3245610, AppleNet: 00104218, MFG: 3245 - this was also a recent buy off ebay, severely damaged due to battery leak, had a 30MB SunRem hard drive.
Interestingly the apple net IDs of two of these both start with 104, but one is the new B SN and the other an older A SN - this might be a clue.
And here's a couple off recent ebay listings:
SN: A33344145 AppleNet: 00108638 MFG: 3334
Here's one from a chassis on ebay that's being chopped up and sold as panels:
SN: A3197327 AppleNet: 00103676 Mfg: 3197
Another on ebay today:
SN: A3181120 AppleNet: 00102120 Mfg: 3181 Interestingly in this one the AppleNet last 3 digits match the SN's 3 digits. Possibly coincidence, but perhaps it means something (obv. what we're looking for is a unique count, if what you said was correct about AppleNet IDs, perhaps the first 3 digits have to do with a plant number.(as an aside, I wouldn't buy this Lisa, it has severe battery leak damage - also that's an ADB mouse from something like a PPC Mac. Current price on it is $300 but it will cost a lot of time and effort to repair.)
One of the ones on ebay match the MFG date with one of mine: 3334 so this could be useful as an estimate of how many were made on that day.Mine has SN 150, the ebay one has 145 (and this is already in that spreadsheet). So I'd guess there were at least 150 made that day (assuming MFG is by day and not week, and we don't know if that was continuous, day by day, or bursty.) (Edit: that chassis bottom plate has S/N 327, so ~300/day/factory is the high end so far?)
Another in that spreadsheet has A3341046 - so one day later, but SN 046. So it looks like each SN is by day made, and not sequential. But this one's applenet is 00110381 and mine A3334150, AppleNet: 00108643, so yeah, perhaps the AppleNet ID is the way to go. The delta between the AppleNets is 1738 - that seems a bit high. Were 1738+ machines made between two days across all factories? Or did they skip numbers? If they skipped the actual number of Lisae would be far less than even 10K!
I'm starting to think that the date code is not very useful as a way to get a count as they're all "low" day by day - in the low 100s, but then all the AppleNets seem to start with 001; in that spreadsheet the highest one is around 8000, and one of mine is 0010:8643. So far it's all under 10K.
What would be useful would be to find serial numbers that are sequential from the same day and note what their AppleNet numbers look like, are they also sequential? And then find two that span two days, i.e. MFG: 3333 and MFG: 3334 and see the delta in the AppleNet. That would give us an important data point: are AppleNet IDs truly sequential? And then if so, what's the highest we've ever seen.
It would also be very useful to know when we come across 2/10s - i.e. what's the lowest SN for a 2/10, what's the highest SN for a 2/10, since presumably at some point before deciding to switch to "Lisa is now Mac XL", they switched to making 2/10s. But then again, did all factories immediately switch? or did some pump out 2's and 2/5's for a while from old stock?
The big difference is the I/O board, wiring harness, motherboard and the Widget ofc, but this would mean the chassis for a 2/10 is also different and you couldn't slide in a 2/10 mobo+I/O board in a 2/5 without taking most of the chassis apart to change the wiring harness. So most likely this was only done at a factory.
I also wonder if the keyboard SN's could also yield some clue - if we can figure out what part is unique and whether they're sequential.
At some point, I'll come back to this thread and post all the CPU board SNs from Service ROM, this will take a while due to being busy with other things, so it will be after a long while, most likely once I recap my video boards an power supplies.
@bluesnowkitty - are you able to make use of that German Tank Problem math in some way with this?
