ISA is heading for death however it seems. The most recent reports are all citing intel as going to make cheaper chipsets with no ISA support and we all know what that means. Instead they'll be pushing what looks suspiciously like an attempt to reinvent MMX and mwave with an audio/modem riser card and software modem. > > One can muse that perhaps USB (and maybe even FireWire) > > will allow this, since dealing with a few wires and interface designed to > > work with long wires will be easier. > > USB is not easy to interface, but ... If you want a simple interface for wiring toys too that you can build out of bits of bent wire, 8 bit microcontrollers and parallel ports, and that has a huge range of existing compatible components use i2c bus. You can bitbang i2c on a parallel port and it can be quite quick (1Mbit) over random pieces of wire. i2c is what holds the control circuitry of the average tv set together ( and incidentally why tv cards for PC's tend to use i2c onboard). There is linux backend support for i2c too.
