I recently got the Eagle schematics of the SCSI-64 thing I designed. I'm going to put that on the Web when I have time to have a closer look at it (next weekend I guess). > I suggest that you use André Fachat's OS/A65 as a base for the system. > Didn't he already have a filesystem implementation?

But it is a simple FAT12/FAT16 PC-like filesystem. At the moment I am working on it to expand the partition size over 32M (The old DOS problem - well it knows how to use multiple sectors per cluster already, but it can now only handle 65536 sectors. I am working on making the sector number 32 bit - but with a 16 bit cluster number that is starting to really waste space.) > In my opinion, interfacing a hard disk directly to the C64 doesn't make > sense, except if you are religious about it and want to do without a PC. > Speaking of which, last year you and Frank were playing with the thought > of connecting the C64 to a PC with DMA, so that the PC can access RAM and > I/O in the C64 address space without requiring any software to be > downloaded to the C64 first.
