Turbo worked fine before the expansion. (It has an actual turbo switch to select the speed) The motherboard is a Super K. I had to experiment with the jumpers first to allow access to the added memory. Got that finally, but no Turbo. Should I have added the 384K to the motherboard first? (It is full of 64K chips) I've tried software switches to no avail. They either do nothing or lock up the system. HELP!!
