PAK issues

[PhilC]

I get bombs with J4 on and off.

Good News! So, thanks to PaulJ I got myself some other eproms, the ones I had been using were TMS27C010's. Swapped out with some Winbond W27C010-70 and Ive booted to desktop!

[PhilC]

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..

[PhilC]

Ok cool, have done that.

What willi need to do for the patch?

[pakman]

What are the GemBench test results with these jumper settings?
The PCB patch will follow this evening, when I am back home..

[PhilC]

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.

[PhilC]

Reseat the MFP and I have a working Mega again, knew it had to be something silly.

Anyway, here's the gmbench results as requested. Btw, I have no glitter in this machine.
