What
distinguishes the two series?
As noted, I don't know. I'm hoping that someone like Tony does.
I saw the other message on this topic after I sent mine.
I hope that
"16K" means "16/64K model" as opposed to "actually equipped with
16K of memory."
Your hopes are dashed. The only pricey IBM PCs are the ones that had 16K
installed at the factory and weren't upgraded. The 64K ones are relatively
common, although worth keeping; it's like the difference between a Lisa One
and a Lisa 2.
That's absurd (bordering on perverse) -- what could you DO with a machine
like that? (Yes, run BASIC and use cassettes... I know.)
