There has also been significant interest in the CBM
world for an uIEEE

the IEEE bus I am considering both the 75160/75161 versus a pair of
input buffers and a pair of TPIC6B273

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.
You have enough I/O pins for the HP-IB bus ?
How fast ist this AVR reading and writing from sd-flash ?
