8088 Ram Test

[scommstech]

HI
Does any body have a 2764 ROM for sale with just a simple ram
write and read test for the 0 bank on a 64k XT clone.
I want to uses it to replace the BIOS ROM so that the board will
enter a ram test on boot.
I’ve got a board that fails on ram and I need to have a continuous
test running to pinpoint the prob. I've replaced the ram, and
all the RAS,CAS,WE, ADD, DATA, look ok. It may be a timing prob.
as some bits sometimes pass.
If you have can you get in touch.
Regards
Harry W
