I'll see what I can do to come up with something. It's going to be Win32-based. > Is there any documentation about AES MMFM format online? Not that I know of--heck, I can't find any documentation on the original machine as it is. I had to "brute force" that one; complicated a bit by the bit order being backward (i.e. USART order, not floppy order). To date, I still don't know what the machine model is--just have the floppy written by some journalist back in the 70s. > Typo in the part number?

Yeah, that one--brain fart on my part--I was looking at the WD data comm products book, which looks just the same as the storage management products book and picked out what I thought was the data separator. Regardless, I'd like to see what the 9216 details are. I suspect it's nothing more than a counter-based data separator, but it's remarkable for how well it works. Shouldn't be hard to incorporate into an FPGA or even a CPLD. --Chuck > -- --Chuck ------------------------------------------------------------- "The first thing we do, let's kill all the spammers."
