Lisa Tank Problem
« on: Yesterday at 05:55:01 pm »

Gonna spin this off from Ray's sales speculation thread...

Took a couple of hours here and scoured the internet for Lisa serial numbers and AppleNet numbers. Found a good few results thanks to old forum posts and eBay listings. Have a look-see, and if you want to contribute your S/N and AppleNet, post 'em here.

So here's some observations... You all probably knew most of these already but for future reference. This list doesn't account for Macintosh XL units.

  • There's two distinct formats for the serial number, one being prefixed with B08B while the other is simply prefixed as A. The first five numbers of the B serial seem to correlate to year/day of manufacture (i.e., 82100 would be 100th day of 1982) and the remaining 3 is the Nth machine made that day. The A prefix has a 4-digit date of manufacture in an unknown format, the remaining numbers are the Nth machine made that day.
  • The 68kmla link above states that any machine prefixed with a B in the serial means it was a Lisa 1 that got upgraded to a 2/5. Where did this info come from? Seems like there's a number of Lisa 1 units, still un-upgraded that are prefixed with a B.
  • As far as I can tell, there seem to be no difference in AppleNet continuity between B and A units.
  • Was Apple making 2/5 and 2/10 units side-by-side up until the end? Or at least, using up surplus parts until the end... See how there's 2/5s sitting right alongside 2/10s? Weird.
  • Highest number I've found so far is Applenet #10858 which correlates with wherever Wikipedia got their 10,000 units number. But does it account for the 2,700 dumped in Utah, or the units converted to Mac XLs?
  • This one might be one for Al if he's at liberty to talk about it - B08B820360010, or Applenet #65 is the second known oldest Lisa in existence currently, not counting things like the corroded proto from Facebook, or Digibarn's naked Lisa prototype or the GLM. If you search for the serial number, you'll find it listed both on the CHM's website and on Christie's - so did someone at the CHM have really deep pockets, or did the CHM offload a machine out of its collection?
  • What's with this weird serial in the attachments?

Judging by the current data, it seems that there were at most 12,000 - 15,000 Lisas sold as Lisas.
