Hi Andre, > I didn't follow all the discussion, are these ROMs available > somewhere? There are two versions at zimmers.net http://ftp.zimmers.net/anonftp/pub/cbm/firmware/drives/old/8050/index.html. The dump speeddos-fdc-f800.bin is wrong. (If you need it, i've a rebuild version, too.) But i think you can use the fdc-2.7b.bin for a 8250LP or 8296D. The dos-2.7b.bin must be a patched speedos without the copyright notice! For a Micropolis 8050/8250 you found the ROMs at http://www.forum64.de/wbb3/board314-au-erhalb-des-c64/board13-sonstige-commo dore/board16-cbm-rechner/29778-cbm-8250-edotronik-umbau/ Martin > Am 16.
