well I /am/ pretty smart (just inexperienced with MCUs)...

When your electronics budget per month is $0.0 and your monthly parts 
expenditure ends up being ~$40.00 you have to think of creative solutions 
for things or... wait. It's part of my personal philosophy to use what I 
have first. And I have TONS of parts - I just have to think of creative ways 
to use them. If I can't come up with a clever or elegant use for them, then 
I move on.

I have tons and tons of shift registers and shift register latches, both 
CMOS and TTL, 74194's, 4094's.

But I looked on eBay a little bit ago and it would probably be most cost 
effective for me to get a UV lamp for erasing EPROMs as I have scores of 
27XXX EPROMs with things on them. And burners look pretty cost effective 
too... I love eBay.
