(...) Hmmm... why not do this? Use a 74273 and tie it to the HB's data lines and strobe it with Y0 (or Y2 or Y4)? This would create a latched output "port" at address 0x4000. Tie two of the 74273 outputs to the 'A' side of two [N]AND gates (...) (28 years ago, 7-Feb-97, to lugnet.robotics.handyboard)

(...) Since there's some prototyping area, why not just make them regular CMOS signals and include application notes on the web page on how to use the signals for various options. How does the expansion board mount? Looks like it plugs into the top (...) (28 years ago, 7-Feb-97, to lugnet.robotics.handyboard)

What I mean by active is that at this point I could install some kind of beacon or transceiver which could echo signals sent by (...) (28 years ago, 7-Feb-97, to lugnet.robotics.handyboard)
