Hi,
I've got a vintage Power Series 4D/310 upgraded with the IO3B & IP17 (rev 030-0235-005) boards (like the Crimson). However the processor is only a (NEC) R4000 50 MHz one. According to
this page you can upgrade this processor to a R4400SC-150. However you also need a new processor PROM rev 070-1200-001 DB20. My old one is rev 070-0815-001 DAoB
Can someone provide me with a dump of this rom, or tell me if faster R4400SC's can be used with the IP17 board.
