Is anyone aware of any programs or demos that run under the original NS Kitbug please?
Anything at all? I've tried but cant find anything significant.

The reason I ask is that I'd pondered shuffling KB+ so the major calls are at the 'standard kitbug addresses' but if theres no software theres no advantage.

There is a precedent, the 'fixed' Kitbug (without the "bit 7 set" bug) didnt preserve the original PUTC address

If there is no software out there, ie nothing that relies on the original Kitbug addresses, then the plan is to give KB+ a call-table in low memory so future monitor additions wont affect system calls

Because its grabbed my interest, I'll continue to tinker and add to KB+, and it would be nice if routine addresses didnt change on every release.

Cheers
Phil

Hi Phil, is there a concise list of the Kitbug+ routines and their addresses/parameters? I know where PUTC and IPRINT are located, but if I want to dump memory contents on a detected runtime error is it just a case of setting P2 with the address and calling DUMP?

I'm quite enjoying this new fangled KitBug thing

Its P1 Ian but the problem is when its done 8 lines it jumps to the monitor command loop, so if its called from an external program it wont return to it

Cheers
Phil
