Basically, I have done the job. I'm able to read and write with either
SPP, PS2 or EPP protocol. The CRC processor of the Backpack drive is
screwed up when writing with EPP-16 or EPP-32, eight bit EPP is ok,
and reading is possible even with EPP-32.
I'm able to use the ECC coprocessor, too. I need to clean up the
source code and I`ll probably release a preliminary test version this
week, and aiming at a new major ftape release with support for those
beasts for end of July, or end of August.
