Does anyone know if there exists a socket for the National 18200. My application warrants the need to be able to replace the chips if they should ever fail. thanks for any information Patrick (28 years ago, 14-Feb-97, to lugnet.robotics.handyboard)

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)

JTW, Use 1n4002, 1n4004, etc - they are higher rated parts and usually the same price (which is why 1n4001 has been discontinued - everybody upgraded for free!). Richard ___...___ Reply Separator ___...___ Subject: Signal Diode Author: (...) (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)
