Is there anything unique about the 64K x 4 memory chips. I purchsed 8 at my local electronics supply for $73, about half of what Tandy is asking for their upgrade. Are there any jumper that need to be removed/added to allow the machine to recognize the addional 256K of memory? And help or advice will be greatly appreciated.

There are no jumpers, just plug the little guys in correctly, and the BIOS Rom software will figure it out for you. *********************************************************************** Earl W.
