Re: Apple Lisa data on Wolfram Alpha

Rebecca:

A few points of clarification about your Lisa 1 data specs which I'm sure others will have more detailed and more correct replies.

| Original Price: $9985

Recall $9995 (source: Apple Product Introduction Plan [PIP])

| Number Sold: 100000

This is way too high from what I recall. I remember corresponding with one of the Lisa developers (Larry Tesler) many years ago and he mentioned a number around 30,000. Not sure if this is for the Lisa 1 only or both Lisa 1 + 2. Suspect this is for both.

| Graphics Processor: ?

Lisa supported a bitmapped screen which means there was a dedicated portion of memory which a simple circult just streamed out to the video tube. There was no dedicated video processor.

| 5.25" Floppy Drives: 2

Should list capacity of 860 KB each.
