Hello, I noticed that in Figure B.9 on page 194 in Appendix B of the 6.270 manual that pins PE0-PE3 are shown to go to seperate little port symbols while pins PE4-PE7 go to a block labeled 'Analog Input Header'. Do these inputs really go to two (...) (28 years ago, 13-Feb-97, to lugnet.robotics.handyboard)

The latest expansion board schematic shows an LM324 for the high impedance input buffers. Although the LM324 is cheap and available, its input and output voltage ranges are limited to 0 to 3.5V (yes, probably a little more with any real part). If (...)

There are two fundamentally different ways to go about writing assembly language programs for the Handy Board: 1. Write them as callable functions for the Interactive C environment, using the as11_ic program. 2. Scrap Interactive C entirely, and (...) (28 years ago, 12-Feb-97, to lugnet.robotics.handyboard)

The 1N4001 is the 50v version of a family of diodes (1N4001-1N4007) that cover 50 volts to 1000 volts. In general you could use any of the other versions. I would recommend looking for 1N4002(100v) or 1N4003(200v). As it happens Digikey says they (...) (28 years ago, 11-Feb-97, to lugnet.robotics.handyboard)
