Lisa Tank Problem
compu_85:
Do we think it's safe to assume that the serial numbers for a given day start at 0? If so the 15k estimate just seems super low.
Is the math wrong on the "calculations" tab of the spreadsheet? It's coming up with just over 11k, with 219 serial numbers tracked.

Just seeing this thread now. It's a great initiative, thanks blusnowkitty. I have 3 Lisa's at home, plus another one that I have fixed for a friend. My latest 2/5 (Lisa 1 upgrade) does not have a SN sticker, and is not operational as of now so I can't get into the ROM to find out. But here are the three I know of:
Serial Applenet Manuf
A3333115 108163 3333
A3248711 105102 3248
A4248514 106907 4248
PS: I didn't know about the German Tank math problem. Really cool https://en.wikipedia.org/wiki/German_tank_problem

Can you note if those are 2/5 or 2/10 models?

Certainly:
Type Serial Applenet Manuf
2/5 A3333115 108163 3333
XL A3248711 105102 3248
2/10 A4248514 106907 4248

My understanding of the math tells me this is correct (see Wikipedia link I sent). The estimate is slightly higher than the highest Applenet number. And the more SN we get, the closer these two numbers will be
