Joe & I had originally hoped to offer a 1.5GHz module with 16MB L2. That was our initial plan. Then the Sandcraft chip didn't
seem so much like it would be possible, so we aimed for 900MHz. Note the L2 was to be 50% faster than normal (IBM told Joe
this was important to help match the faster CPU clock). Alas, without the PROM source, not gonna happen.
To clarify, here's the response I had from SGI as of Jun/09:
Code: Select all
In response to you request to release the prom code, our position is unchanged. Similar to
Intel's treatment of PAL as a micro-architecture extension of their processor, SGI manages
PROM source as strictly proprietary and any release to the public domain is not an option.
PS. I have a slightly different theory. I don't think they even have the PROM source anymore. My guess is the dev systems
have long since gone, ditched during shakeouts, Chap11, buyout, etc. I know the ICE-dev systems went long ago.
