Wheres the easiest place to stick a probe on the 50mhz clock?terriblefire wrote: ↑Mon Jul 20, 2020 10:13 pm Put the scope on the 030 CLK vs the 8Mhz clock.. they should be in sync and squared off until it hits fastram.

on the CPU socket... And remember its not 50Mhz most of the time.

So just to confirm what I'm looking for, an in sync 8mhz signal between the two clocks until it switches to fastram.terriblefire wrote: ↑Tue Jul 21, 2020 8:41 am

I'll take a look when I get home later, thanks.

Re: Getting a TF536 working on my Mega ST.
I saw clock switching just sitting on desktop, so its not constant 8MHz ?

Yes I Guess I can switch that off for The purposes of testing. It switches fast when AS is disasserted

Re: Getting a TF536 working on my Mega ST.
@exxos @terriblefire heres the two clocks blue is motherboard clock and yellow is on the 68030 before fastram kicks in.
Are the two clocks supposed to be in phase?

Re: Getting a TF536 working on my Mega ST.
Whats looking bad is the presumed 50MHz cycles which look like the scope probe are loading it to much. looks like you are on x10 already though ?

Re: Getting a TF536 working on my Mega ST.
Yes, new probe freshly calibrated too.
Putting 200pf on clk to gnd makes it get to ram check but it crashes after a lot of Xs

Re: Getting a TF536 working on my Mega ST.
It does look like the 8MHz is inverted
EDIT
Actually I don't think it is...
EDIT2:
Did you try 1K pull up on 8Mhz. ?

Re: Getting a TF536 working on my Mega ST.
@exxos not inverted, i tbink out of phase slightly
Edit, didn't try pullup but will now. As well of 200pf or by itself?
