Macintosh IIsi: How To Invoke Interrupt with MacsBug
I'm having problems using the programmer switch on a Macintosh IIsi. I'm
using MacsBug and have tried Command-Power On and Control-Command-Power On
to no avail.
To invoke the interrupt on a Macintosh IIsi through MacsBug, use the "hot
keys" Command-Reset. And it's important that you use the latest version
of MacsBug.
