The purpose of the ROM SIMM slot was never for ungrades, per se, but for firmware corrections which became necessary during the period between first, limited production and final, volume production. Apple's philosophy was a machine should do precisely what the specification book said it skould do, nothing more, nothing less. The only Macs in my recent memory to actually have a ROM SIMM issued for/with them was the 9500. The early production had a ROM SIMM, and that mother board was labeled "Tsunami w/o ROM". The later production had soldered ROM, and the mother board was labeled "Tsunami w/ROM". All the other PCI Macs had provisons for a ROM SIMM, but this was never used. Now, the Apple Network Server (ANS) was loosely ... very loosely ... based upon the 9500, and some have tried a 9500 ROM SIMM in an ANS, but that won't make it a Mac. However,the ANS is based upon Open Firmware, and it may have been the first Apple machine to be so equipped. That makes upgrades to Linux (from its native A/IX) more straightforward, but it can't get around the fact that the toolbox (in the ROM SIMM) which is necessary for MacOS is just not there. -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
