Just posted a small summary of parts of "The Steve I knew" - John Couch said it was closer to 100K units, but so far we don't see any above 13K AppleNet wise. Hmmm.

Ray, does this Lisa have the same AppleNet No as one of your Lisa's? If so this would indicate that the Applenet No is perhaps not unique?

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.

I don't think that AppleNet matches any of mine, just did a search of that google sheet and it's not in there. I added all of mine there (except for the spare CPU boards)
It is possible that there were duplicates, but I'm not aware of any. I'd imagine that duplicates would be bad for networking in a hypothetical large corporation purchase, but yeah, even ethernet Mac addresses were known to be faked and duplicated when certain brands didn't want to pay the IEEE or whatever.

Nah, as far as the AppleNets go it does match to what you put in as Machine A3245610... so this is curious, do we have a genuine from-the-factory Applenet conflict?

Interesting. I think I see why I didn't find it, I hit control-f but probably had javascript off for one of the google domains, so FireFox's find didn't find that AN#, however, when I turned it on and do a find from the find field inside of the spreadsheet it does find it. That is very weird. I'll have to go through my Lisas again to confirm it wasn't a typo on my part.

Ok, so it's confirmed, there's at least one duplicate AppleNet, this one is a 2/10 that had MacWorks with Minifinder on the widget that I got off ebay ~August 2018. The previous owner got it from an estate sale; it had files indicating a family on Long Island owned it in the mid-late 1980s - this is the one that had that copy of Lotus Jazz on it.

But if there really are 10x more Lisas than the 13K, there should be a lot more duplicate AppleNets, and we don't see that. However, since there is one black swan, there could be more. The big issue then is how many?

So the serial numbers aren't sequential but likely unique and the AppleNets are supposedly sequential, but now we find they're not unique. Ow!
WTF was apple (not) thinking!

Thanks for confirming that Ray.

The eBay UK listing I linked to also indicates that machine was "Assembled in Ireland" on the model/memory option sticker (rather than Made in USA), and the model number ends in P presumably to indicate that Lisa was fitted with a 240 volt power supply.

I assume the programmed VSROM and serial number sticker were likely produced in the US factory, as the plant number is the well-known B08B in the serial number, and therefore a different plant number did not need to be assigned to the factory in Ireland assembling Lisa's for the European markets.

I wonder if the duplication of the AppleNets is allowed between the A and B serialnumbers or maybe 2/5s vs 2/10s or maybe an accident. Hard to say since we have only a single black swan to look at. :(

I'd expect if there were 100K vs 13K Lisae that we'd see more AppleNet number conflicts - like the birthday problem it should show up more often rather than just once. Then again birthdays are 1-365(366) but AppleNet numbers are 001xxxxx so 5 digits long vs 3 and that spreadsheet is a bit small at the moment.
