Pre ATW800/2

Before the ATW800/2 was released there were some (more limited) predecessors:

The STG[A]TW was a hybrid of the STGA graphic card adapter to an ET4000 ISA cards and a TRAM carrier.
It was a testbed the get more familiar with the Mega-ST bus and its capabilities.

Released revisions

Only the Mark 3 models were released and sold to the public. So all Revisions start with a "Mk3" marking.

V1.0d - First public release. Sold in the 1st batch of 50 cards
V1.1 - 2nd batch release. Differences to V1.0d:
- Removed (optional) buffer for external T-Links
- Removed option for supplying 3.3V to the Nano20k
- Removed the chip-select solder bridge for the C011
- Added solder bridge to choose voltage for SMD/THT 5MHz oscillator
- Expanded USB connector to 2x5 pins to have external USB controllers to provide power to the USB port
- Added solder bridge close to the USB port for power-source selection (card or in-port)
V1.1a - 3rd batch release
- Added ROM Enable jumper (which does not work without a little patch)
- Minor layout changes to simplify the building process
V1.1b - 4th batch release
- Fixed ROM Enable jumper "bug"
