I have some questions about the various options for the PCjr.
IBM 128KB Memory Expansion - There are dipswitches on this card, does anyone have the settings? How far can you upgrade the memory with these particular cards? 256, 384, 512, 640, 736K?
IBM Power Expansion Unit - I hear that these cards can power about three sidecars a piece. If you have six or seven other IBM sidecars, would you need one or two of these sidecars?
IBM Attachable Joystick - How long is the joystick cable?
IBM Internal Modem - Can this Modem, with its non-Hayes compatible command set, be of any use?
Finally, what is the best way to get data from a modern PC to the standard PCjr? One way is to have a 360KB 5.25" drive (even the PCjr.'s drive as drive B) in the not-too-modern PC and write software to disks. Any other method like direct parallel or null modem would require custom software to be loaded on the jr. first.
