[comp.sys.cbm] CBM user port to standard rs232 converter

hackeron@athena.mit.edu (Harris L Gilliam) (03/29/91)

I have seen articles in the past that mention a simple CBM user port to rs232 
converter that can be cheaply built. Does anyone have the schematics for such
a beast ?

If the machine you intend connecting up to has the RS-422 standard, then
	there's a simple&cheap 3-wire null-modem you can build
	(two plugs and wire)
