WOW, your prof let you use NANDs? we had to do this using only
relays. Wish I had an easy prof like yours.

You were allowed RELAYS? We had to use frogs' legs. And catch the frogs
first.

Based on the OP's email address, the thing should be implemented using only
Aristotelian propositions.

If I were your prof, and I caught you blatantly trying to get others to do your
thinking for you, I'd make you design it using nothing but BC547's, resistors
and diodes. That way you might l-e-a-r-n something. That is why you are at uni?

Why would he need diodes?

You didn't want to bet with Lady Ada - she had one of those betting
schemes that had made many bookmakers rich. Betting against her didn't
work any better.

Can anyone send me a 4-bit binary divider circuit in this email :
kkaranasos@in.gr ? I must make this homework for my university and i
am late.
I have to make this circuit only with NAND gates.

PLEASE HELP !!!!!!!!!

Thanks a lot

In a few years there may be a job for you at the NY Times as a
technology correspondant. Just make it up as you go or dredge it from
the net. It wouldn't be anymore crazy than the real thing.

Happy new year every one

You had gears and levers? We would have given our right arms for gears
and levers! Cowrie shells was what we had, and were glad for it.

It has weird navigation. I found it by right-click/open in new window
on 'Projects' link near the top. Not obvious...

You still don't need the diodes - it's wired-or logic.

divider? I think you've already known how to build multiplier... make
one then turn it up side down, and voila you have divider.

But the OP wanted to use only NAND gates. Oh well, an inverter on each
input will turn an OR to a NAND, and as we're already spending
transistors by the bucket might as well go for it.

Easier than that, just define Vcc(ish) as 0 and ground(ish) as 1.

Most of the DTL logic I worked with was "Negative NAND" logic. 0V = logic
0, -6V = logic 1.
