     Well, it must be that time of year, because here's another weird
Amiga problem that I'd like EMAIL about, if possible...
     First, my system configuration:
     Amiga 500, 1 meg RAM (via A501 expansion; obviously, this includes
a real time clock), two floppy drives (second drive a *&^@*#!!! AIR drive),
modem (Mitsuba 1200), monochrome composite monitor (the 1084 is also in
the shop. Still. Since July.), multiple printers (Tandy DWP230 in IBM
Wheelwriter mode (hardware locked in :-) ), Diablo C150, Panasonic
KX-P1091i). 
     Secondly, the new and weird behaviour:
     If the second (external) drive is hooked up when I power the system
up, its drive light stays lit. When I insert a Workbench disk into the
internal drive, the system ignores it entirely. No reaction whatsoever.
     If the second (external) drive is NOT hooked up when I power the system
up, the system boots normally and initially works correctly. However, at some
semi-random point in the near future, the system will lock up. This tends
most to happen when someone tries to click on an icon to open a disk,
utility, or application.
     Removing additional hardware from the system does not alter the system's
behaviour beyond this point. Also, the problem is apparently not with the
power supply; I disassembled everything and moved the A500 over to another
desk (upon which sits another A500) and hooked it up to the other's ps,
monitor, and etc. It exhibited the same symptoms.
     My suspicion (i.e., my guess) is that I am losing an I/O chip. Could
someone please confirm or deny this?
                                                 - R'ykandar.
