 | | HB assembly errors. —Vincent Gracchi
|
| | | I am now using the Windows 96 version of IC 3.1 Beta and it works great on my Pentium Pro. My PC now talks to the serial interface board as outlined in the assembly instructions. However, the PWR LED never blinks on the Handy Board. IC also returns (...) (28 years ago, 19-Oct-96, to lugnet.robotics.handyboard)
