Hi all,
My first post on this forum! I thought the C128 was rare enough these days, so to see a dedicated forum is great!
Ok the business; does anyone have documentation on the burst IEC protocol. I would like to know exactly how it works.
Currently I'm implementing the IEC in C64 style in software on a 6502 based homebrewn diskdrive (more on that later on in case someone is interested). But since I'm testing the lot on a 128DCR I thought why not investigate my options on burst mode.
So if anyone can get me going please do.
Thanks
Erno
Here's a few links (some with code) to get you started.
First some reference for most Commodore drives:
http://www.classic-games.com/commodore64/drives.html
there's probably some related references here as well:
http://www.zimmers.net/anonftp/pub/cbm/c128/
Next some same assembly routines for the 64 (should work in the c128 I would think:

The article from c-hacking (http://www.ffd2.com/fridge/chacking/c=hacking) in issue 3 has a section devoting to bursting your 128 specifically, here:

This should be good to get you going :-)
Hope it helps.
