One of the few dead HP calculators I own is a 10-B; I've ignored it. Today, though, I found an HP-42s at the local thrift shop, missing the case and battery compartment cover, it was priced at $us1.99. The battery cover and case from the dead 10-B fit perfectly; is there some difference (transparancy) that I should be concerned about?
Found a use for a dead 10-B (doing happy dance)
