I haven't been watching the net lately, so I don't know if this has been
recently answered.
I have a friend who is interested in buying an A500 system and a hard drive
(20 MB min.) and that is all.  He would like to know of he can modify the A500
external hardware port to accept an A2000 controller card.  He needs to know 
how different the pinout is from the A2000 internal cards.  He has *NO* fear
of modifying the A500, including running a multitude of jumper wires for any 
missing signals.  (Yes, he will invalidate the warranty.)
Power supply.  Anything you can supply.  I don't believe the A500 can handle
the increase.
If I can come up with a cost-effective alternative to purchasing an ST or an
XT, we will have another Amiga enthusiest (sp?) in our ranks.  Help me, please.

P.S.  He does not want the expense of an A2000.  All arguments for an A2000
(including mine) he will ignore.  Do not think that the job, if possible, is too
complicated.  This gentleman just finished designing, building, and programming
a MC6809 dual microprocessor system using shared RAM/ROM and I/O on a cycle-by-
cycle switching algorythm (sp?).  And he is building a 10 inch telescope to be
driven by it.  If the A500 mod can be done, he can do it.
