Could that be a FORTH module? The last digit is hard to make out. Could be '0' or '9' but the loop looks too small for a '0'.

I suppose it could also be 5061 7238 which is the Surveying ROM (with only portions of the smaller upper loop visible), which might also make sense for a high-end machine with lots of RAM inside. The style of the '8' in the line below is different, but it almost looks like each character was stamped separately, so hard to tell.

You'll just have to fix it and turn it on I guess to be sure... ;-)
