There are a couple of versions of DLM out there. The one I have I have to type : dlm pcode_hb -ram -256 for it to work on my handyboard. I also have to use it from a DOS 6.x machine, on a Win95 machine it complains about memory errors which are very (...) (27 years ago, 8-Sep-97, to lugnet.robotics.handyboard)

a regulated supply would be really nasty when you put the interface board in ZAP mode -- the supply would try to raise the level of the battery to 15v or whatever, and that would be bad. so unless you really know what you are doing, steer clear of (...)

(...) Isn't this a bit sweeping? Surely the problem is that a 12v regulated supply will not have enough headroom with a 9.6V battery. I use a 7.2V battery without problems (that I am aware of).It is not the regulation that is the actual problem but (...) (27 years ago, 5-Sep-97, to lugnet.robotics.handyboard)

Good question. Answer: DO NOT USE REGULATED ADAPTERS WITH THE HANDY BOARD. I will add this to the FAQ, because it is not obvious, but the HB power circuitry was designed explicitly for CHEAPO UNREGULATED WALL WARTS ONLY. sorry, Fred In your message (...)

Has anyone used Richard Drushel's math and serial libraries with a real serial port? The HB seems to miss about every other character when I use any of the higher level functions. Thanks, Jodi Graf (27 years ago, 4-Sep-97, to lugnet.robotics.handyboard)
