Hi, Can someone suggest me a good and easy to use description about the IEC serial bus used with CBM machines to connect eg floppy drives? Of course I found tons of them, but it seems my brain is not so good about inpreting the textual description ... What I would like is to have some exact diagram/description or so which shows every IEC bus lines and what happend and when (important timing constraints, etc) throughout an average data transfer, etc (let's say loading and saving a file from/to the disk). At this time, no special fast loaders, C128/1571 SRQ line etc is needed, but the very basic protocol used with C64 with the stock KERNAL & 1541. http://jderogee.tripod.com/projects/1541-III/files/IEC_disected-IEC_1541_info.pdf http://www.zimmers.net/anonftp/pub/cbm/schematics/misc/iec-protocol.gif These seem to be quite OK for me at the first sight, but I am curious if someone can suggest better resources? Thanks a lot in advance & btw happy new year. - Gabor Message was sent through the cbm-hackers mailing listReceived on 2013-12-31 19:00:04
