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 an error message about not being able to talk
to the HB. When I assembled it, the HB passed all tests. I was only able
to measure the voltage on the E pin for clock test. While trying to debug
the board I realized that when power is supplied by the SIB to HB and HB is
off the BATT LED is brightly lit and PWR LED is faintly lit. This seems
wrong. I checked the HB mail archive and did not find any mention of any
similar assembly errors. Please excuse my forward behavior but I purchased
the parts to assemble two HBs. One for myself and one for my nephew. He
has been looking forward to building the board for months now. I promised
him that we would build his this Sunday after church. I was building mine
so that things would go smoothly on Sunday. I would hate to disappoint him
so I would appreciate any suggestions. Thanks.

Typically, if you are powering your system from the SIB, this indicates some kind of board short. I would remomve all (...) (28 years ago, 19-Oct-96, to lugnet.robotics.handyboard)

| Could someone please tell me what the MISO, MOSI, SCK, and SS pins are on the 68HC11 and why they are wired to a 4x2 female header? Also how would I access these (from code) if I wanted to do something with them. Thanks G --- Garth Webb (...) (28 years ago, 20-Oct-96, to lugnet.robotics.handyboard)
