[snip discussion about Compact Flash cards]
On a somewhat-related subject, is there currently an easy way to use a PROM as a read-only filesystem?
I.E. I'd like to write a raw filesystem image to an PROM using a PROM burner then connect that, probably to the parallel port, and use it as a block device.
It should be fairly simple to build the parallel port -> PROM adaptor, as it would essentially just be a ZIF socket, and a whole load of latches to multiplex the limited number of I/O lines to the 32 or so needed for address and data, and the driver should be straightforward to write as well.
Or is there a reason why this hasn't been done? PROMs are much cheaper than Compact Flash...
