So would I (is that thw oen with an SPI-like interface?). But another

commenting that if such a device was created, it could also use CF cards
with little, if any, modification.
I'm not sure if I'm the list member in question, but uIEC/IDE uses the
AVR ATMEGA1281 and provides an IDE/CF interface. However, the same
firmware also supports SD cards (and is available as uIEC/SD).
There has also been significant interest in the CBM world for an uIEEE
solution, so I have sketched out a solution that utilizes the AVR. FOr
the IEEE bus I am considering both the 75160/75161 versus a pair of
input buffers and a pair of TPIC6B273
<http://focus.ti.com/lit/ds/symlink/tpic6b273.pdf> high current output
drivers. Currently, the 7516X units are a price premium, but the price
difference is minimal.
The uIEC firmware currently supports FAT16/FAT32 and SD/SDHC/IDE
protocols already, I simply need to write the IEEE support.
I'm happy to have help :-)
