[ burp ] This surprised a few of my Amiga friends, so maybe it's useful. The date command with a ? argument will prompt from the window for the date; this is useful in startup-sequence. Also, does anyone have any idea why a second drive requires about 30K? Do they load another driver, or what? Thanks! -tom

Each drive requires a buffer which is as long as an entire track's worth of bits in their encoded form, with one clock bit and one data bit for each "actual" bit of data. With 11 sectors per track, two heads, and 528 bytes per sector, that adds up to about 24K. Add a little more to allow for slop, and you get to 30K pretty quickly. This isn't exactly the most ELEGANT way of doing a disk driver, but it does allow such goodies as reading most of the different 3-1/2" disk formats out there... -- Mike Farren uucp: {your favorite backbone site}!hplabs!well!farren Fido: Sci-Fido, Fidonode 125/84, (415)655-0667
