The picstart can be used on the faster Macs.  It ends up taking very long
to compile larger programs (some of mine can take 15 minutes on a 6115
running softwindoze).

Wiring of the serial cable to the picstart is important and a bit abnormal.
About a year ago Karl Grabe showed me how to do it. This is what I have
saved from then.

Here's what I found...

It only works on my PB180 with Soft AT only when most of the extensions are
off.
It works on a Power PC running Soft windows (Native) in dos mode with all
the extensions on.
It won't work on my Duo 230 with Soft AT at all. :-(

I find I'm still not totally clear on which pins are what but if it's wrong
I just flip it. I think the apple modem tool is correct if you use it to
look at the open end of the female on the picstart, or printer or whatever.


I found that a female DIN8 packages fit nice in a 9 pin D-sub cover. Just fill
it with hot glue. Makes a cute short adapter.

Thank you so much for the tip. Can I distribute it freely?
