The quick question is: Does anybody have any suggestions on a cheap, easy to use single board prototyping computer. The one I really like is the BCC BASIC-52 computer from the August 1985 Ciarcia's Circuit Cellar. It has a built in EPROM programmer and initially starts up on my terminal. I'm not sure if it's still available or if there might be some newer and posibly cheaper things in the last 5 years. If you have any ideas, please let me know. The specifications for the interface I am going to add to this board are listed below. If you have any ideas on these too, I'd also be very gratefull. Input: Wind speed (probably 1-5kHz frequency counter) Wind direction (probably just switches) Above must be optically isolated (i.e. against lightning) I have very little idea of how to do this yet. Telepone ring indicator Output: Speech Synthesizer to telephone line Hang up It would also be nice if I could get it to turn itself on and off only when the telephone rings. Thanks. Eric. _____________________________________________________________________________ | Remember when sex was safe and hang gliding was dangerous? | |-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-| | Eric Brown 940 Mt.

You should check out the "Little Giant" from Z-World Engineering. - integrated C development system (compiler, source debugger) runs on a PC - real-time kernel s/w - 9 MHz Z180 (64180) CPU - 512 bytes EEPROM, battery-backed CMOS RAM (28/32 pin socket), 28/32 pin EPROM socket (C in ROM). - 6 counter-timers, 4 serial ports, 16 25mA parallel port bits, LCD interface, 8 channels of 10 bit A/D, RTC (time/date), watchdog timer, power-fail detect, bus expansion connector - analog signal conditioning for thermocouples, current loop devices, etc. - +8 volts unregulated in (wall xformer included) - 4.8 x 5.6 inches (fits in standard (Pan-Tec) plastic project box). - Price: $395 (board) + $195 (Dynamic-C development pkg for PC) Look in Oct '90 Byte page 349 (or any of the last few months). Usual disclaimers, I have no connection, blah, blah ... -- bmw@isgtec.uucp [ ..uunet!utai!lsuc!isgtec!bmw ] Bruce Walker
