Sirius 1 (aka Victor 9000) on Ebay (UK)

The hardware is a bit odd... It clearly shows the Chuck Peddle influence, it's full of 6522s (3 on the mainboard, 3 on the disk controller), and the disk read/write circuit is very similar to that in a Commodore PET drive... A couple of odd things. Firstly, the Centronics port is driven by GPIB buffers (75160 and I think 75162). A 'little matter of programming' and the right cable would get you a GPIB port there, Then there's the user port. A 50 pin header on the mainboard. It's almost a complete 6522 (I think one of the port lines is used to clock the sound circuitry), along with a light pen input and power lines. Odd.... And the sound iput. THe encoding half of the codec is wired to the receive side of the 6852. The input to that codec comes from a pin on header on the mainbosrd (along with power lines, ground, etc). It would not be hard to feed an audio signal in there, the hard part would be to write/find the necessary software.... -tony
