LC III - odd problems

[thekhakinator]

LC Boards are tricky.

You can also use Ceramic Surface Mounted Caps as well.

Yeah, I'd definitely like to do that in future. Mail order's expensive in Aus but if I get this board going strong, I'll totes spec it with some sweet longer-life caps.

i have some lc3 boards pm me.

I may do this if further experimentation doesn't net me a solution. I just can't quite bring myself to give up yet.

I did check - it doesn't have the 33MHz overclock. My second LCIII that has been overclocked runs fine, amusingly.

Just if anyone's interested in some amusement, you can watch the LC III crash in an absolute trainwreck manner here.

I'd like to properly reflow the board in an oven to see if that helps but I'm worried about melting the connectors; anyone know how they hold up?

you need a dissecting microscope and look at that VSLI Chip and see what pin(s) are iffy and with a steady have you can touch up those points. Putting it in the oven will, in my opinion, will make things worst.
