I can think of the following options, restricting it all to I/O gadgets that plug into the serial port, for simplicity of discussion: 1. use a small 68k logic board on batteries, software loaded into RAM (RamDisk), no diskdrives connected anymore, together with an I/O gadget) like the MacIO II that was mentioned yesterday. Measured data could be pulled from the MacMissile(tm) after landing. Talking to the I/O gadget can be done in HyperCard etc. 2. use an I/O gadget, and a radio transmitter ( e.g. a mobile phone) in the MacMissile(tm). On the ground, the SE/30 also uses a mobile phone to send/recieve the data to/from the gadget. Basically, you extend the serial cable by going wireless. 3. Customized microcontroller board like Atmel's, Scenix SX, PIC's etc. For *some* of these little wonders, there are Mac programming environments available. I have one here: 'Mac Pic 68k'(1999). The ReadMe says: "The MacPIC shareware program is a tool for editing, assembling, debugging, and programming the PIC microcontroller. All functions are contained in one program for an integrated development environment." The package includes Editor, Assembler, Disassembler, Simulator and Programmer. About 40+ PIC-devices are supported. The vastly available info on the PIC's themselves is usable; only the fact that it's done on a Mac is different. The board itself will be just like the ones you'd buy/design with a PC. 4. a somewhat larger missile with the footprint of an SE/30? :) Guestimation: Getting the software to work (for any of the above) will take more time than the hardware.. -mart -- Compact Macs is sponsored by <http://lowendmac.com/> and...
