In case there is anyone left out there, I've just solved multiple problems (obsolete hardware) by buying a netbook that runs XP home. XY4 Dos was easy to set up. I added some old Word software (via a cheap external DVD drive) so I can convert Xy files to Word docs for delivery. I added an Avant Stellar keyboard (with function keys on left, and PS2 to USB cable), remapped CTRL, ALT & CAPS LOCK.
Everything works perfectly. The keyboard, remapped, also works fine on my Mac iBook, with Xy4 running nicely in DosBox.
Remaining needs to enhance the experience:
1. an inexpensive LCD monitor somewhat larger than my netbook screen.
2. a cheap, super-light remappable keyboard.
Any suggestions?
