Supra 500XP head scratcher!

[curtis]

Picked this up from a fellow a while back.

Has original 52Mb drive and 1Mb RAM installed.

Tried it on several A500's versions 5 and 6a with and without other expansions.

KS 1.3, 2.1, and 3.0.

All but 1 when I move the mouse, it starts down and right!  The one that works properly is 1.3, but when I try it with another 1.3, mouse takes a dive!

Checked dip switches and they're correct.

Power off and pull the XP and power back up, everything works perfectly!

When I tried it with a 3.1, I did get a report of a bad expansion board.

Any suggestions on fixing this POS?

Thanks,

Curtis

I would expect it to work with any 1.3 rom.

IIRC, the stock rom was only compatible with 1.3.  TJLazer (frequents this site) sells an updated rom for the 500XP.  I believe it will allow OS3.1, larger hard drives, and removable  media.  He can tell you more.

I have a 500XP that will be partnered with a Turbo28 when I have space to set up the system.

Well, seeing how I really don't have time to get hip deep in another project, I think I'll put this up on ebay starting at a $1 and see what happens.

Metal is in good shape and, heck, the hard drive may be good.  See if I get any takers!

Of course, it'll be AS IS!

IMHO, the 500XP was one of the better sidecar peripherals.  If I didn't already have one, I'd buy it from you myself.

Where are all of those jokers, who blame all of our communities ills on hoarding, when you need 'em.

Another double post?
