Please, no. HandyBoard is fine, but it is 20+ year old technology.
If you can all hang in there another two months the answer will be JCX:
http://www.jcx.systronix.com
512 KBytes SRAM (this can be used just for heap - working data space)
512 KBytes to 2048 KBytes Flash (for code and file system)
32-bit 3.3V current technology CPU with 32-bit registers and 32-bit
internal memory
prebuilt code support for all the standard Lego motors and sensors
prebuilt code support for 1/4 VGA LCD with touchscreen, others in the works
(1/8 VGA)
8 sensor inputs per plug in board, Lego(tm) compatible, multiple boards allowed
4 motor outputs per plug in board, Lego(tm) compatible, multiple boards allowed
backplane 100x100 mm with six slots (CPU + five I/O boards)
RF Modem and bluetooth in development
compatible with Lego electrical connectors
Add your own plug in board for other sensors, motors, etc
Already compatible with color image camera CMUcam, code already written to
support this
Most of the code support will be open source, user contributions welcomed
Optional Super CPU with 2 MB RAM, 4/8 MB flash, 10BaseT ethernet
Target price for base system with 8 inputs, four outputs, first listed CPU,
backplane, software US$500
etc etc etc
It really will be here in first half 2003, we plan to demo at April and
June trade shows in San Francisco
I realize all the above is not trivial, that's why it has taken us nearly
two years to develop.
Sincerely
Bruce Boyes

| I haven't really looked into HandyBoard, since I found it to complicated compared to the RCX. 20 year old tech works fine on the Space Shuttle and other NASA projects BTW. JCX seems nice, but $500 for a replacement is getting a bit steep for the (...) (21 years ago, 7-Feb-03, to lugnet.robotics)
