I imagine that the idea is that changes to the FAT will be written immediately; the copy in memory is only to avoid extra read accesses. > Or you use it on Floppies and swap > them... Now that is a problem. The +3 has a similar problem (and I once accidentally wiped a disk because of it and had to examine each sector to reconstruct the files), but it copes by invalidating the cache after about 3 seconds of inactivity (my problem was caused by typing NEW within 48KDB because that resets the frame counter and fools the timer). Fortunately the FAT of a floppy disk is small enough to read quite quickly on startup. > Different tack. Bob (THE Bob) asked me if there is a CHEAP Z80 > assembler that works on a PC. Not on an emulator... Any ideas? No (wouldn't be that hard to write one though surely... :-) ). imc
