I've not seen that device in this country, or any tools to support it (such as the EVB). Perhaps I'm not looking properly. A device I have seen and am quite interested in is the TMS77C82 microcontroller, sold through Maplin (and probably other sources). It looks quite sweet, with some features which may make it suitable for interfacing to The Glove. It's a 40 pin device with 8K EPROM and 256 bytes of RAM, and is programming compatible with the 27C64. Some of the specs:- 500KHz - 6MHz clock input 3 - 6 Volt operation 15mA @ 5V, 4MHz (operational) < 20uA (Halt state, interrupt wakable) 32 CMOS I/O pins 3 16 bit Timers 1 serial port (internal or external baud rate generator) I'm not sure what the machine cycle rate is, but with a serial port it looks as though something like this could provide a low chip count interface, and the chip is available. Personally, I am using an NEC 75316 4 bit microcontroller (16K OTPROM, 512 nibble RAM) in my ultra-sonic 3-D digitiser, because I use this chip at work and have all the debuging tools. -------------------------------------------------------------------------------- Mike Hibbett | Philips Radio Communication Systems Ltd Tel: INT + 44 223 358985 Ext.3310 | St Andrews Road, Cambridge, CB4 1DP, England ----------------------------------+--------------------------------------------- Philips DECnet: PRCS3::HIBBETT | EUnet: hibbett@prcs3.decnet.philips.be --------------------------------------------------------------------------------
