NEW IDE Controller & TOS 2.06 board (with extras)

Hi all,

I've been working on a little project that's an IDE controller & TOS 2.06 upgrade for the STFM & STE. So, I wondered if there's any interest in it.


Basically it has the following features.....

* IDE Controller with two ports, one primary which is Atari compatible and bootable. The second is compatible, but not bootable. Therefore providing 4 IDE devices.

* TOS 2.06 address decoder, with external pins for ROM's (or ROM upgrade board

* Primary & Secondary ports are switchable.
Consider this, you boot from your primary drive, but it becomes corrupt. You flick a switch to your backup drive on the second port, and now it becomes the primary port and kazam your back in business.

* Possibility to stack the board, therefore offering upto 8 IDE devices (still testing this one)

* HDDriver support for both primary & secondary ports. (Already talked to Uwe about supporting, and he's currently giving me some beta versions for test).

* Possibility to go into the STE - currently with adapter - shown. Later it's possible to switch out the 68000 DIP socket for this directly. (Just tested with STE motherboard I got from Chandler :D )

* Finally, it's all done with Logic chips. A challenge I set myself to fiddle with stuff 8) . Therefore easily solderable for those who have the skills, and no programmable chips are involved, obviously if it's just the bare board.


Currently the two 40 pin IDE connectors are vertical. I'm considering mounting the primary (the one closest to the edge of the board) at 90 degrees, so the CF card would be horizontal in the shots.

The photos show where I'm at and these are prototypes so there's been some slight modifications to these boards.

Feel free to send comments :cheers:
