[A83] Re: Stupid Idea?
The design I was thinking of would involve maybe 2 AAA batteries, an
ASIC, and some other misc. circuit crap. Prototyping would be done with
an XSA-100/XST-2 Board (www.xess.com), with a SpartanII FPGA. Since the
calc only runs at 6 or (12?) MHz, timing constraints would not be a
problem. If the project could be completed, I foresee the drive acting
very similar to regular TI-Graph Link transfers. Naturally you wouldn't
stick in a 512mb compact flash card...Probably a 4 or 8mb would be much
more than sufficient. I think the FAT file system would be the best file
system to implement, because you could then just drop files onto the
disk using a USB drive for your PC.
Does anyone else know VHDL on this list?

It would be like a link system to the better part of a Palm. You need a
communication system from the calc to the device, then this IDE or
PCMCIA
controller, and a fast system to do indexing and maintain a file
system. The file system data, once developed by the fast system, would
have to be transmitted compressed across the link port. You might look
at
the PSX memory card interface that was developed by a guy at ticalc
awhile
back. It was mostly complete, and one guy actually built one into his
calc. Supposed to be pretty sweet, its in the news archive.
