Hi all.
How easy is it to add commands to osi basic for the multicomp 6502 8k rom image ??

Some pointers would be helpful as it looks like simply adding an entry to the token table ??

I got the source to compile but im looking to add a c64 style sys call and a monitor call.

Thanks in advance. Lee

This is how it is done in EhBasic: viewtopic.php?p=7791#p7791

You will probably find that it is similar in osi basic.

Bit late with the reply sorry. I have done it. I added commands for my homemade machine. I can't remember the details now though as it was so long ago but I did blog about things and there might be some pointers in here: http://www.asciimation.co.nz/bb/2013/10 ... ning-basic

I haven't done anything on that machine for a long time now. Life sometimes gets in the way of the fun things (career changes, moving cities and I have too many other fun things to distract me)!
