ProDEV built a debugger board for the IIe and IIgs in the late 80's. They have made some kits available for folks to build thier own.

Please see http://www.prodev.biz/DDT/ddt.htm

This forum is here to help foster discussion/assistance on building/modding these boards by folks who have bought the kit.

Lets help each other.

cool!

I bought one. I read the "readme" that came
with the documentation:

"great effort has been expended to make the DDT
source code the most exquisite example of spaghetti
code the world has ever known"

That's no joke about being spaghetti code. 16K bytes of program running in a 2K memory space by bank switching the EPROM with 256 bytes of code in a non bank switched location. Plus a bank switched RAM. The darn thing even runs code in a 16 byte memory space reserved for card I/O.

I pitty the poor fool who trys to analyze that code. :)

I've read csa2programmer newsgroup for a few years,
including Paul Santa Maria's posts.. I never knew he
was involved in commercial Apple II products. The above
link says he worked for ProDev inc, the company that
manufactured the DDT card

Yes it' is true. Paul has been a friend of mine since we met at an Apple II user group meeting, many years ago. He worked for ProDev for a while as a programmer.
