S100 RAM replacements

All:

	I decided to run a memory test on some boards I have and I found a
bad chip. It's on a CompuPro RAM14 and the chip is a MM2147J. None of my
other 16k boards has this chip (VG boards; contain 2114s but the boards have
"BAD" labels on them so I've never plugged them in). The chip does not have
a speed marking that I can see and I don't have a copy of the RAM14 manual
although it might be similar to the Godbout EconoRam IV which uses the
40144/mm5257 chips.

	Can anyone help me with a suitable cross for this chip...and a
source? My usual haunts don't show stock on this number.

	Thanks.
