So, I definitely have a early-model WP-2 (26-3930) that has all the serial communication problems (3930A supposedly fixed at least some of those issues) and an early ROM that makes CamelFORTH crash.
OTOH it seems to speak PDD protocol without any issues so I don't really care how good or bad it is at xmodem... ;-) And, unfortunate as it may be, I don't actually know FORTH. And the RAM disk chips are apparently bog standard low-power CMOS 8x32K and 8x128K chips. Shouldn't be a problem getting those. I have all the BIOS functions coded into WP2.DEF, now I need to read through the old CIS files, a d00d published some corrections to the typically error-ridden Tandy docs there. He also did a pretty cool graphics demo. :-) Also, worst location for a power button in the history of power buttons! :-) Willard Sent from Samsung tablet
