I remember seeing the hot-stamp machine to the left of the counter in Borland's store. Someone was often using it when the store was open. BillA told me GGS got the hot-stamp machine and the dice when the old 'The Gambler' store contents were sold. He said he threw the machine and stamping dice into a dumpster to prevent anyone from making more. Anyone interested in Borland chip history might want to contact Bill in the Ozarks an confirm this.
