All of this progress on emulating the early SPARCstations raises a good question: We currently have dumps of a bwtwo card (1-bit monochrome display), a cgthree card (8-bit color display), and a cgsix card (accelerated 8-bit color display), but are there any others floating around?
SBus was interesting in that it's almost guaranteed for a card to have a dumpable ROM on it. The reason for this is that the boot monitor and OS both probe the base slot address for an identifying word, as well as the name of the card, at a minimum. The ROMs seen so far range in size from 2 kilobytes (bwtwo and cgthree) to 32 kilobytes (cgsix).
Furthermore, is there anyone out there who has any SBus cards not yet dumped and who has the capability of desoldering and dumping them, or at least sending them off to someone who can do so?
