-I've never seen nor heard any verifiable reports of the H&P 68k emulator (that's the one you want them to use, right?) being 1) Complete 2) Faster than current 060's. From the rumors I've heard, it may reach @040 speeds, but it doesn't have the capability to store translated M68k instructions in memory, so it isn't going to get a whole lot faster unless you step up the processor power a HUGE amount, or you start caching instructions.
From what i recall the 040 speeds were that of the H&P 68k emulator under a 604e ppc. And i recall somewhere, forget where, but one of the companies who were offering to make ppc boards claiming the g3/300 getting speeds of 150% speed of an 060 based on some existing benchmarks from a macintosh 68k emulator.
H&P have posted some remarks regarding the speeds of their emulation but i forget what exactly they were now.
Regarding the two 68k emulators, from a posting i have here they are going to use both emulators. H&P and their own. But one will be resident in a flashrom one will be disk launched emulator i think.
Actually i just found a posting from met@box via ANN i kept from 24th of february or so regarding the emulators.
regarding 68k-emulation: met@box has two emulations in development, optimized for the pipes of the G3/G4. The first one is in a Flash-ROM and will reach about the niveau of a 030 - 040. An update for this emulation will only be necessary in case of any bugs. The second emulation will be loaded from harddisk at booting and brings the full speed. For this one there'll be regular updates for improvement. Current calculations show, that a PPC needs about 3.5 cycles (? - german: "Takt") for the emulation of one 8/16-bit-68k-command; 32-bit-commands are emulated in ca. 1.5 cycles, so that, regarding Thomas Rudloff, already their entrance-model will be better than an overclocked 68060. Important would be the possibility to switch between 68k- and PPC-code, so that a partial port of AmigaOS and applications would be possible. The second generation of emulation is already planned and will be much faster.
Martin Heine posted that news to c.s.a.misc back then.
