  Re: GCC 2.8.1 for HC11
 
Curt, I can't help test with a miniboard, since I just have a handyboard ("just" have a handyboard?). But I'd be willing to give any help I can with the handyboard libs. I'm also a willing guinea pig for trying out your gcc-2.8.1 patch and README. (...) (26 years ago, 2-Apr-99, to lugnet.robotics.handyboard)
 
  Re: Simple questions
 
(...) The problem with a 12V, 1A *unregulated* power supply is that when you hook it up to a device that draws significantly less than the rated current, the power supply will probably deliver significantly more than 12V.

  Re: GCC 2.8.1 for HC11
 
The HC11 back end for gcc-2.8.1 is working on Red Hat Linux 5.2 (and probably most other Unix hosts), and last night I made the cross-assembler and cross-linker work with it properly. It compiled/assembled the GCC Miniboard library last night (...) (26 years ago, 2-Apr-99, to lugnet.robotics.handyboard)

  Re: PC vs Unix
 
(...) I use a PC running Unix (ok, a Unix-variant). PC and Unix are NOT mutually exclusive. :-) I agree with the other response: Unix works well. The easiest to learn setup is probably Interactive C on a PC or a Mac. Once you're comfortable with it (...) (26 years ago, 1-Apr-99, to lugnet.robotics.handyboard)

  PC vs Unix
 
We ordered a HB the other day but were not sure if we could use unix to operate it as opposed to a PC. My question is: do you have to have PC to operate a HB or can you use unix. Ethan Getz ethang3@hotmail.com ethang@unm.edu (26 years ago, 31-Mar-99, to lugnet.robotics.handyboard)

  Re: Help needed!
 
If you're having problems getting your HB to work on one serial port but it works on another, you might want to check for IRQ conflicts. By default, Com1 and Com3 both are assigned IRQ3, and Com2 & Com4 are both assigned IRQ4. So if you have a modem (...) (26 years ago, 31-Mar-99, to lugnet.robotics.handyboard)
