Cool, all assembled, ready for some testing

I was testing Franks blitter demo and noticed something odd when the blitter is enabled...

It looks like the background isn't be cleared/restored :shrug:

When in 8MHz mode, or using CPU render, it is all fine.. so something is tripping up somewhere :roll:

So not sure if I've done something daft but..

The STe gas been running fine but the GB6 results just look like that of a standard STe.
I'm running tos2.06 , the ce wire is connected to ce pin on fast rom board with resistor in between and sw has nothing connected.

Have I forgotten to do something?

As long as you did not connect SW to GND (it enables 8MHz mode).. nothing else to it...

You did remove the old CPU (only other thing I can think of)

Yeah the old cpu is sat on the table as we speak.

The floppy drive is touching the socket for the rom but I have taped that and will bin the floppy for a gotek eventually. Could it be the ce wire?

And as I said, sw has nothing connected to it.

GB figures attached.

odd.. check pin 1 of the GAL make sure you have 40MHz there... I did test the boosters before I sent them out, so no idea why its stuck in 8MHz mode unless the osc has died. :shrug:

Mine should be going in tonight, so I'll report back on here when done.

Nothing at pin 1 of the gal but an 8mhz signal at pin 2.

As far as I can tell there us 5v going to the osc but not a lot coming out.

Can you check the contacts on the osc itself and make sure it has 5V on top 2 pins, gnd on bottom left, and 40MHz bottom right... either its a bad solder joint or the osc has died..

Actually checked that after I posted earlier, so looks like the osc has died.
