Does anyone out there in the net land know if 256K RAM chips work in the empty sockets of AT&T PC 6300 on the Motherboard? I have heard rumors that it does and if so one can have full RAM (640Kbytes) right on the motherboard without wasting a slot and pay the high cost of buying a board. If you have any info on this I would appreciate it if you would send me mail and let me know. Thanks, Reza Zarafshar ihnp4!ihlpl!reza0

I just found out from AT&T that they do work they have to be 150 nSec chips and you have to change the switch setting on the mother board. The setting is as follows Switch 0-1 off Switch 0-2 on Switch 0-3 off Switch 0-4 off I looked at the Byte magazine ads and found out that these chips are around $18-$20 a piece. Considering how much it costs to buy a memory board and that one expansion slot is wasted I think it definitley is a good deal. Reza Zarafshar (312)979-5235 ihnp4!ihlpl!reza0
