A theoretical question

Postby OldComputerGuy » Fri Mar 24, 2017 5:26 pm

I know that the PSU of the Jr is only capable of supporting so many sidecars before additional power is required. Would it be possible, in theory at least, to use a more powerful PSU and have the power carry through the sidecar bus to support more sidecars than the standard PSU can handle?

Not only is it theoretical but it has been done. PC Enterprises had a power supply that sat in a Drive II assembly and plugged in to the PCjr power slot. I have also heard of people adapting XT power supplies to do the same. I would think a ATX power supply could be jumpered to turn it on and and adapter attached also.
