Are these good for snes repros? The number is right, but how do I tell the read/write speed?

27c801

that is the correct Eprom to use but their is no way of telling the speed from what they have posted... only way would be to Message them and ask them to list exactly what is writen ontop of them... something along the lines of 27C801-150 or 120 or 90 could be less or more but I haven't looked up all of what ST's product lines are...

Thank you Ian. Appreciate it
