A85: Re: return of OS hardware
can you design and build a working version /w little time and money? if you
can, send me the WORKING plans and i'll see if i can build it easily.
I agree witht he extension ports thing. Those should be present in
abundance.
About the standardization, we should use several: TI's I2C /w MBus
extensions, etc. Then the program decides what is needed. but we need you
to design this thing ASAP. If it works, we may give it a try. If it costs
much more than the e2 does, then no, because that will work for our purposes
as well, and more ppl know about that and can easily buy/build one for
cheap.
But, go for it! Design and build a working model and we'll see.
