Subject: [alt-beam] 74HC14

Hi- This has been bothering me for a while now, what is the difference betw=
een the bicore and the microcore? The microcore uses a 74HCI14 I.C and the =
Bicore uses a 74HCT240 I.C right?

I learnt about the Microcore yesterday, on Andrew Miller's site. He explain=
s that, if you put LEDs on the ouput of each Neuron, you should get a "Satu=
rated" state. Then if you add a switch, and hold it down for around two sec=
onds you should get a two process state, for another 3 seconds, should get =
a stable one process state. Then he talks about cycling through the microco=
re's useful states with a PIN switch and a PNC switch connected together. N=
ow this is where i'm confused, where do you connect the PIN , PNC switches,=
do you connect them to every Neuron, where do you connect the motor driver=
s and motors?
How many neurons can fit on a single 74HCI4 chip?

Help would be greatly appreciated.

Cheers
Andrew Waters
