You can unban yourself if needed. It also sends me reports to investigate the ban.
DO NOT USE MOBILE / CGNAT DEVICES WHERE THE IP CHANGES CONSTANTLY!
At this time, it is unfortunately not possible to whitelist users when your IP changes constantly.
You may inadvertently get banned because a previous attack may have used the IP you are now on.
So I suggest people only use fixed IP address devices until I can think of a solution for this problem!

So the plan is now that I enable each cache, etc and will then do Gembench tests for each step, just for the hell of it.

So, a big thankyou to Pakman for your help in bringing my Pak to life.

And here's a quick benchmark.

The spec at the moment is cpu and CPU running at 32 mhz. Cache and tag ram installed.

Not sure why the ram reads slower though.

Now change the jumper setting as follows:
J1=off
J2=off
J3=on
J4 has to stay on for now.. since there is still the PCB patch pending..

Amusingly it doesn't boot this morning. I'll check for loose connections etc.

Have the grand kids over again today, so also won't be able to do much till later.

Edit:

The mega has died, bloody typical. Will try the Pak in my other Mega later on, whilst I fix this one.
