You could get +5 from the PC Power supply, its runs at a very stable +5V at that.. I plan to implement a PC backplate complete with about 4 PC plugs connected for external +12v and +5 support *nt*

: Thanks for the info.

: In discussions with Chris (Fultra) we have decided to go down the route of designing our own optical board, which will fit on the Fultra spinner and the Happ trackball.
: One interesting point: This problem does not arise if the PS/2 port is being used, as the PS/2 mouse port supplies a "solid" +5 volts. This is probably why that new Hagstrom interface uses this port. I think this a less useful option, as it limits flexibility. For example no 2-player trackball games, no EMU+ etc. I reckon sticking to the serial port(s) is the best way to go, and leave the PS/2 port for a real mouse in Windows if required.
