From my notes on upgrading my 2109E to run RTE-6/VM:
"I used a Data I/O 29B programmer to burn the PROMs, with a Unipak 2B.
The blank PROMs were variously Signetics N82S141, MMI 6341-1 and National
74S474. Along with the 12821A HP-IB board, you also need a Boot Loader
PROM, 12992H (12992-80004). The boot loader PROM is a Signetics N82S129 or
equivalent. For installation information about the firmware PROMs, see
manual 12791-90001 (HP 1000 M/E/F-Series Firmware Installation and
Reference Manual). For boot loader information, see manual 12792-90001 (HP
12992 Loader ROMs Installation Manual)."
