I'm using a Rockwell chip, which has a maximum slew of 10ns. The datasheet for the 7404 that I'm using says the typical low-to-high switching time is 12ns, but when I tried it out, it seemed to work.

When I ordered the oscillator, I also ordered a couple 7404s. I'll try building my own clock circuit again.

Sorry I haven't posted back. I left for a vacation and then for a camp shortly afterwards. I got the can oscillator and I'm freerunning my processor now.

I'm going to order one of those can oscillators (probably what I should have done in the first place) In the meantime, I'll try a 4049. Thanks for your help.

The computer I ran the test on was running in dos. I had a cut-up printer cable from a previous project, so I put it in bidirectional mode and read from it. I can see what you're saying, that I'm just measuring the speed of the parallel port rather than clock, I think it really is that slow because ...

Thanks for the advice. I found some 270 ohm resistors and got my processor running.

The datasheet for the processor had a clock circuit that didn't have a capacitor in it, so I was wondering about that. I wrote a test program to try to find the clock speed, but I'm unsure of my results.

It sends ...

I have some questions about the clock circuit I'm using.
On one of the sites linked to from the projects section I found this clock circuit:

I don't have a 7404, but I have some 74S37 nand gates, so I connected the inputs on them to make ...
