Dear Dennis,

"There is a free windows-based debugger/disassembler/simulator that I found with a quick search here ("Search 8052.com...", see left). Looks pretty good.
"

What is the search term ? Better if you had just told the name of it directly.

I use the Pinnacle simulator and it is all I need. Simple to test out a few lines of code, math(s) routines, and register values. As long as you dont want any checks on timer interrupts, I think Pinnacle is good.

Thanks

Raghu
