>>1. Does Daystar still produce '030 accelerator cards, and do any of them work with a IIcx? (I have seen '030 cards still advertised, but are they really still around?) DayStar still offers the 50 MHz Universal PowerCache, $349, $449 with FPU, that triples the speed of the IIcx. You also need adapter A31CX-000 for use with the IIcx. This adapter attaches to the original 68030 CPU socket. Many IIcx's have a soldered CPU. To check what type you have, call DayStar's fax catalog service, 800-438-0370, and get document # 7001. 2. With either '030 or '040 accelerator cards, is the IIcx resident fpu disabled if the card has no fpu, or do floating point operations just not get accelerated? That is, in order to run fpu-dependent software, am I forced to get a card with fpu? The Universal PowerCache will recognize and use the system board's 68882 FPU at 16MHz if an FPU is not present on the accelerator. This is NOT the case with the Turbo 040. The FPU support is integrated in the 68040 CPU if enabled. External FPUs are not supported by the 68LC040 CPU used in the 33 MHz Turbo 040i. There are software utilities that emulate an FPU, but these are much slower than silicon versions. 3. On either type of card, what is the power requirement? I currently am running two video cards, so using both of those and an accelerator might be stretching the limits of the IIcx power supply. Both the PowerCache and Turbo 040 have low power draws. They can be used with all three NuBus slots filled. Greg Erickson DayStar Digital
