If you're willing to share the code, I'd be
interested in taking a
look.
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? The WD9914 is WD's
second source (or
clone?) of the TMS9914 GPIB chip.
I was able to find some info on the internals of the SMC FD9216 data
separator. WD second-sourced that as the WD9216.
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.
