Supported devices are:
<ul>
<li> Empty
<li> Southwestern Data Systems Datakey - SpeedStar (copy protection dongle)
<li> Dynatech Microsoftware / Cortechs Corp protection key - CodeWriter (copy protection dongle)
<li> Southwestern Data Systems' datakey - SpeedStar (copy protection dongle)
<li> Dynatech Microsoftware / Cortechs Corp's protection key - CodeWriter (copy protection dongle)
<li> Robocom Ltd's interface module - Robo 500/1000/1500 & RoboCAD 1/2 (copy protection dongle)
</ul>
NB. Copy protection dongles can interfere with joysticks (eg. buttons may be hardwired to a fixed state), so only use dongles with the intended software.<br>
NB. Copy protection dongles can interfere with RGB cards (eg. unexpected video modes may get selected).<br>
