032- Today my IIgs started "stuttering"-- i.e. working

for a bit then freezing for a bit then working again.

Anyone have a fix?

I have seen this before. The cause was a bad connection to the keyboard's

mini-DIN-8 connector. One of the leads from the connector to the keyboard

circuit board had broken its solder connection; and, the line was intermittantly

connecting.

When one or more lines is broken or loose, information is not getting back

to the computer or is interrupted. Seems like the computer is waiting for it;

and, you get "stuttering".

The solution was to resolder the mini-DIN connection(s) on the keyboard. I

did it and all is fine.

The keyboard's min-DIN connectors are fairly well known weak spots on the

IIgs; and, I have repaired more than one keyboard for bad connections. In one a

copper trace going to a connector was broken-- repaired that by soldering in a

jumper made from a bit of solid copper wire.

033- How can I use a PC mouse on my Apple II?

I have developed a small adapter which lets you plug a PS/2 mouse

(mechanical, optical, cordless, etc. as used with IBM PC-compatibles) into an

Apple mouse port. It works with the mouse port on the AppleMouse card and the

built-in mouse ports of the Apple IIc, IIc+, and Laser 128. (It should also work

with older Macintosh models (128K, 512K, Plus); but, I don't have one to test it

on.)

The adapter, which was demonstrated at KFest 2003, has a pair of

microcontrollers which translate the PS/2 protocol into the Apple mouse format.

No software changes or drivers are needed on the Apple side.

I've set up a web site with pics and info for selling the adapter via

PayPal at ...
