Does anyone have direct experience replacing the eproms in a M7554-PB?

I managed to erase two 27C128's and burn them this morning but I discovered
that the instructions I found on the web
don't match my board (very nice instructions, none the less - thanks!)
I may just try it and see what happens, or reprogram the 27C256's with
the image doubled, just for fun.
