Hallo allemaal, The email of Ramses pointed me to the fact that the name "PC-card" could cause confusion. As it is still in an experimental phase and the new name is tells you more about the nature of the card and therefor will cause less confusing, I changed the name to "ISA-card". Other ideas are still welcome. Something about the status. I did some results and made some assumptions: - 16-bit I/O operations only use one single address which can be odd as well. - all memory related cards are able to perfrom 8-bit transfers By disabling 16-bit transfers to memory cards, I simplyfied the needed boolean equations in such a way that they at least were handable and, very important, they could be translated in hardware. I'm still in the proces of minimizing the number of needed gates but I now can say it can be done! Until yesterday I had some worries about the second 8237 but due to a remark of Nick I solved that problem as well. Stil have some minor questions but these are all about the actual design and use of (which) IC's. Groetjes, Ruud http://Ruud.C64.org - This message was sent through the cbm-hackers mailing list.
