Info about Apple Widget drives

[Patrick Schaefer <PSchaefer@epost.de>]

Because working Widget and ProFile drives are nearly unaffordable today
(at least in Europe), I have designed and built a ProFile emulator. For
those who are interested, here is some info:

http://john.ccac.rwth-aachen.de:8000/patrick/idefile.htm

The web page is far from finished, but it should give a first impression
of the system.

IDEfile uses a regular IDE drive and a converter board (a 8031
microcontroller with DMA logic) to emulate up to seven "ProFile"
volumes. Up to now, emulation  of the 5MB and 10MB ProFile drives works
fine. Both Apple /// and Lisa accept the drive and boot from it. So my
main goal, to get a drive I can use to play with Lisa software, has been
achieved. However, to complete the thing, I would like to add support
for 10 and 20MB Widget partitions.


If anybody has a description of the Widget, its command set and
firmware, or some information about (or tools for) servo alignment and
low level formatting, please let me know.


I know this is somewhat off-topic, but perhaps anybody out there can
help me?

TIA
