Well, I just thought that I would update a few more people on what is going on
with MY Tool Box by Expansion Technologies.. I guess that I need to fill you
in on a few other things firstly though!  My Amiga has been DEAD for about a
month now due to ripping out my daughterboard and attempting to replace ALL of
my PAL's with new faster PAL's.. Anyway, about a month ago I unsoldered to the
best of my ability (I broke a power pin on one chip (:-<) all 4 PAL's on the
daughterboard and installed sockets in which to install the new PAL's. So, I
went to the ONLY place that had PAL's available on a Saturday and bought some
older version AMD/MMI PAL16L8ACN's and programmed them at work.. So, I install
the darned thing and ... NOTHING! The thing was DOA!  So, I figure that I've
nuked my daughterboard and start looking into alternative replacements. 
Anyway, today I decided to try putting in the old parts and see what happens..
To my total AMAZEMENT, it works fine (I'm using it now!).  It turns out that
the replacement PAL's are too slow for me, so I'll have to get some faster
parts next week from AMD..

Anyway, I decided to install the ToolBox and see what it might do.. So, I
installed the Toolbox as the first item on the external bus and the system
came right up (I've got an ASDG Dual Serial Card installed within it). So,
then I tried putting my ComSpec AX2000 (2 Meg ram board) on the other side of
the ToolBox and (like I figured!) it didn't work -- the system came up, but
the memory wasn't there, or recognized!  So, I put the ComSpec on as the first
bus peripheral and the ToolBox as the second item.. EVERY time I tried that,
the Kickstart screen would come up and as soon as it came up with the
workbench screen and I inserted a workbench disk, within 10 seconds (more like
3) the system would GURU with either the GURU numbers OR without even getting
that far -- the Power LED would just sit there and flash in a circular cycle.
So, I'm hoping that my new PAL's (Low power/10ns speed) will help out the
situation.. But, I'm pretty sure that it won't help a bit..

Also, I've installed the grounding mod!  I also tried using my Bus Terminator
and that didn't seem to do anything much at all..
