Re: COEX 64K RAM BOARD PROBLEMS
Just acquired two COEX (Components Express) 64k Ram cards only to
discover an interesting and persistent bug. It seems that RAM between
1000 - 1fffh is filled with 7eh (0111 1110b) throughout this 4k region
as though b1-6 were jammed high and on BOTH boards. Continuity checks
ok. Anyone know of this problem or bus conflict. The environment is a
Morrow Decision I which has always taken kindly to OEM devices.

Please reply to me. I will relay any answers to Robb.
