Legacy busses

ISA:

Idea is to get 8 x 1 bit / 1Mbps digital data into the PC.  PIC at
40MHz is 10Mips, with one 8 bit port interfaced to an ISA 8bit
register, this is probably really at the limit..  Can I use a PIC as
an address decoder?  For a dedicated PC, maybe it's possible to use a
single address bit as chip select, and the remaining as function
select?


ATA (IDE): derivative of ISA

PCMCIA: derivative of ATA

COMPACT FLASH: derivative of PCMCIA


ISA -> ATA?  I didn't know that..  Maybe this can be used for PIC->PC
data streaming, since the connectors are quite easy to use.

What about PIO 0, 8,3 MB/S 8 bit?
