Mike's PCjr Page

I personally love the grossly over-engineered adapter that converts from DB25 to IBM PCjr proprietary serial. The thing weighs more than the mouse.

Got a power supply from the curator of the forum...


Works great!!

Additionally, I would prefer to build it myself for what that's worth. The "ConnectorPeople" site referenced elsewhere on this forum does appear to still have the sidecar connectors in-stock. I saw that the minimum order was a bit of an issue, it looks like someone would need to buy 3 conn...
