overshoot.
Setting the PROM programmer to Hitachi specifications for the HN27C256 will result in a

Make sure the index marks on the PROM programmer socket, socket adapter, and chip are
properly aligned. If they are not, the chip may be destroyed by excessive current flow. Before
programming, be sure that the chip is properly mounted in the PROM programmer.
Avoid touching the socket adapter or chip during programming, since this may cause contact
faults and write errors.
