Hi guys

I've constructed my 6502 and am trying to test it. As part of this I want to single step the CPU (WDC 65C02S) as my oscilloscope isn't good enough to "see" 2MHz.
Now, going by the helpful guide here (http://www.myheap.com/single-clock-cycle-circuit.html) I can do this. There's just one snag: I don't have any 1uF capacitors and won't be able to get any until late next week.
Is there any other way around this? I.e another method? I have the feeling the answer will be a resounding no, but thought I'd ask anyway .

What do you have that's in the same neighborhood? Other values in the circuit can be adjusted to work with it. There's quite a bit of leeway in timings anyway. It's not critical to hit an exact number.

What's an additional VIA among friends, anyhow?

I've got nothing near it, just the following (these are the markings):

10
22
47
101
102
221
222
472 (blue casing)
473
471K

And a ton of 100nF

Going by the value charts that I've found none of those would do unless set up in parallel - and lots of them

[EDIT] I've just found a 2.2uF electrolytic.

The leakage at the input of the Schmitt-trigger inverter is hopefully (and probably) low enough to replace R2 with 470K use a 100nF (which is .1uF) for C1 and get the same results. (The time constant is the same between 47K*1uF and 470K*.1uF.)

That seems to have worked very well - thank you very much!

I'll post a few picys of the machine in my other thread .
