Hi
I have a apollo turbo 1230 mk2 accelerator card that i have changed the crystal from a 25mhz to a 40 mhz and one of the holes in the pcb board where the crystal goes as solder missing so there is no contact with the board is their any other way of making contact otherwise the machine will crash when using workbench after a period of time any ideas would be gratefull.
The solderpad that is missing is for pin 1 on the oscillator and pin 1 is usually not connected on them so you should be good (if the CPU doesn't get a clock it wouldn't get as far as to Workbench). From experience I'd also say memory issue or overheating issue so would put some heatsinks on the FPU and CPU and use a simm with faster timing 60ns or even 50ns if you can find one.
