 Re: Using Commodore 1541 disk drive on a Commodore + 4

As for the dual drive question: nope, AFAIK there wasn't ever a dual drive for the Plus/4 (or the C64 whatsoever) . On the other hand: the "unit" (as a term) is in Commodore's terminology... There were dual drives in Commodore's profile, even if they weren't produced with serial bus. Still, the fact that the drives weren't produced with serial interface, and the Plus/4 wasn't equipped with IEEE-488 doesn't mean, that it could have been impossible to handle an IEEE-488 drive with the Plus/4... It's all a matter of some interfacing... You could, for example, get an IEEE-488 interface and hook a "big" dual Commodore drive (ie. a 8250) to the Plus/4, ...and then wonder, how you could access the second drive with the "regular" Basic commands, if the "unit" parameter wasn't handled by Basic 3.5 wink . ...Another point is, that Basic was also used in the higher profile Commodore machines (B256 and such ) that were shipped with IEEE-488 and were expected to handle dual drives pretty regularly... Commodore just probably didn't want to drop features from Basic 3.5 that have been implemented anyway.
