Mac II question

I found a nice Mac II yesterday with Natl. Instruments HPIB, 20MB memory, Asante NIC, and framebuffer. What makes it special is that it has a Daystar accelerator that plugs in the 68020 and MMU sockets; the accelerator has a 68040 @ 33Mhz. I had not planned to keep any NuBus machine (I'm tossing stuff out due to an impending long trip), but, since I have the Natl. Instruments software for the HPIB card, and some other interesting Nubus DSP cards, I am tempted to keep it... so I thought I'd ask some questions to help me make up my mind. Does anybody know more about this accelerator? What kind of performance does it yield compared to, say, one of the later Quadras? Are there basic differences in the I/O and bus architecture that will prevent the 68040 from reaching its full potential on a Mac II mainboard as opposed to a 68040 in a Quadra? Do Quadras have faster SCSI? Also, the machine has two floppy drives; how do the Mac II drives rank among those found in Apple machines in terms of usefulness/durability? Thanks for your suggestions, Carlos. -- Carlos Murillo-Sanchez email: cem14(a)cornell.edu 428 Phillips Hall, Electrical Engineering Department Cornell University, Ithaca, NY 14853
