[comp.sys.amiga.programmer] A500 replacement drives

cs441215@umbc5.umbc.edu (cs441215) (01/31/91)

  Since my local amiga dealer wants $150 for a new internal drive, I was 
wondering if an A2000 second internal drive would make a suitable 
replacement for the one in my A500 (ooh, an epson!).  In other words, will
it fit, and if anyone has done this, what brand did you use and what 
modifications had to be made?

Thanks!

Well, there are some complications but you can put an A2000 floppy drive into
an A500. The drive will behave OK but it won't exactly fit. I fixed this problem
by cutting  a piece of metal from the top of the disk drive just above the
place where your disk is inserted. It is best to use a pair of side cutters
to get rid of the excesive shielding because if you use a saw or a file you
could contaminate the diskdrive with the filings (The metal particles would
also destroy any disk you insert.) Some A2000 disk drives have little doors on
them so you will also need to detach that. The button will probably need
changing as well because the A500 needs a longer button in order for it to stick
out of the case. You can use the one from the old A500 drive. There are also
little mounting feet on the A500 that support the drive above the motherboard
just unscrew them from the old drive and put them onto the new one.

One last thing, if your replacement drive was used as DF1: on the A2000 you
will need to change a jumper on the drive. You must find a jumper called
DS0 and a jumper called DS1. The DS1 connection will shorted. You must move
the jumper from the DS1 position to the DS0 position. That should fix the
problem.

The exchange of the drives isn't very simple but if it can save you $150
go for it. If you are handy with tools it should take you about 20-30 minutes.
