Atari Numbers (was: Reiability of wrong media (was: is out of 5-1/4" diskettes)

THese thave been model/type numbers, but at least they where (until the upgraded 1040 with an exception of the 260+/520+ quirk) consistent - The numbering started with the 65XS system (with 65 kilobytes) and the 130XL (double the size) and continued with the 260ST (256K or 4 times the 65) and the 520ST (512K or 8 times 65) - here the 260+ and 520+ comes in, whitch are basicly upgraded 260s and 520s (the 260+ got a full settled memory like the 520 and the 520+ recived a pigy pack memory add on to give 1 Meg of Mem) - and the 1040 is just the last in this series with 1024K or 16 times 65 'kilos' ... These numbers are, within the respective system logical and well defind - and since they are just model number, thy don't have to reflect any technical meaning.
