The component module & the infamous Alpha coprocessor board

Very little facts are known of this board which never passed the prototype stages due to its fragility. It was supposed to attach to a header in the DraCo Motion/Vlab Motion and provide component output.
I have never seen a picture of this device, but it is absolutely not a rumourand it is based around the Philips SAA 7165 chip.


Speaking of rumors, many times during the life of the DraCo, Macrosystem advertised about a DraCo Direct card for rendering video effects in realtime. It was supposely a kind of coprocessor card based around a DEC Alpha processor at 233 Mhz (this was in a time where the Alpha processor was the king of the hill). The truth is, that this card never even reached the prototype stage.
