Thanks I will look

Have you got any arm mobility? I'm thinking you could strap a reel of solder to your wrist and feed it down through e.g. an empty biro taped to the back of your hand, and, well, poke it at the soldering iron.

Almost zero unless it’s a bear hug.... nothing from wrist down.

I have a decent visor ...

And on the flip side of that both my 6502 and 65816 boards run perfectly well at 16Mhz on double sided boards. However I use a GAL (or 2 on the '815 board) rather than a "raft of TTL" to do all the decoding, '816 address bus latching, etc.

Make of that what you want...

Do you have any ...

Also, consider using 74AHC where available. It's practically as fast as 74AC, but doesn't have the powerful output drivers that could cause difficulty; the rise and fall times are more similar to 74HC.

With that said, on short signal paths you should have no real difficulty. That means you're ...

Hi, Steve

You might want to have a look at the thread Techniques for reliable high-speed digital circuits .

I will give that a read, thank you.

There's no exact limit for 74HC clock rates. In fact, at some clock rates it may make sense to use mostly HC logic, with AC used for one or two ...

Hi folks,

Apologies if this question is outside the newbies topic.....

I've read that care needs to be taken with designs using 74AC variants due to ringing. Is there any resource I can refer to explaining the specific design considerations for 74AC over 74HC for a 65C02 and 65C816 SBC?

I'm ...

The wooden end plates remind me of the Minimoog. Very very nice work.
