We are currently using two 68HC11 boards on a small mobile robot and need to get a board with similar size and i/o but improved computational power. We are thinking maybe a 68000 based board. Can anyone suggest a commercial board, (not necessarily 68000) and how to obtain one? Any help here would be greatly appreciated. (please e-mail) Thanks! Mark Yim mark@coyote.Stanford.edu ps. We don't want to make one since we may need 6 boards, and would rather spend money than time.

We had a lot of success with an Omnibyte Mutlibus board, I think part no. OB68K1A. This is a 68010, at least 0.5 Meg memory, 2 serial ports, and 4 8 bit parallel ports. However, this is rather antiquated technology. If the budget isn't tight and you are looking at a multi-processor architecture, I recommend one of the Ironics single board VME computers. There are various models available with 68010, 68020, and (just introduced) 68030s. Different boards have different IO devices and memory configurations. The nice thing is that the boards are designed with multi-processing in mind, and have neat features like dual-port memory, mail-box interrupts, bus interrupters, timers, bus arbiters, etc. The features seem to be well thought out to do just what you actually need them to do. Another thing to think of, going to one of the newer, faster CPUs may eliminate the need for a multiprocessor system, which would really simplifying programming the thing. If you need a multi-tasking system, there are lots of real-time kernels you can run on these things. Other companies probaly make similar products (I know Heurikon does), but I have no experience with them. If you can't find a local supplier, let me know and I can send you addresses for Omnibyte and Ironics. Don Schmitz Disclaimer: I have no connection with either Omnibyte or Ironics aside from being a satisfied customer. --
