- Well while we are on the topic of versatility of patterns etc. -vs- expensive
- designs ... I can't help but bring up the 68705K1. Sorry if this opens a
- can of worms, but it has the 10 I/O lines (16 pin chip) which WILL drive LEDs,
- It will run off of an external RC network (no clock) and it's OTPROM version
- costs $3.50 (yes I finally got some in the mail!). Of course this assumes you
- have the KICS kit.
-
- Sorry if I am getting off track. This really is how I would do it though.
