``The [25MHz 68040-based Radius] Rocket will ship on 25th March. Prices are to be announced shortly.'' So says MacUser UK of 22nd March. As my IIx running A/UX is looking slow these days, I'm interested in something that will take it ``to twice the speed of The IIfx''. But does the Rocket support A/UX? And will it do anything for disk throughput and screen refresh speed -- as an upgrade to a IIfx would? Informed answers sought. Thanks in advance. -- Dominic Dunlop

And that it costs pounds 2,499. This is about pounds 200 more than it would cost to upgrade my 8 megabyte IIx to an 8 megabyte IIfx (at Apple's memory prices). I'll keep you posted on more news as it comes in. Let me know if you hear anything. -- Dominic Dunlop

Its pretty doubtful that the Rocket will support A/UX unless Apple is willing to help us bring it up. > As my IIx running A/UX is looking slow these days, I'm >interested in something that will take it ``to twice the speed of The >IIfx''.

When the Rocket is loaded, the motherboard processor is in charge of all other I/O tasks. This offloads the Rocket processor to do other stuff. Additionally, because the Rocket supports block-transfer, all graphics calls to video cards that support block transfer are speeded up immensly (i.e. All Radius video cards). Included with the Rocket accelerator are QuickColor and QuickCAD to speed up general and CAD drawing tasks. If you have a SCSI-2 card, Rocket can do block transfers directly to/from the SCSI card. In other words, WHOOOOOOOOSHHHH!. #define DRAMATIC_REENACTMENT Scene: The designers of the Macintosh II line. Designer #1: Gee, should the motherboard be able to do block transfers to the NuBus? Desinger #2: Nah, we wouldn't want that, then we could write to the screen 4x faster and our users would be really happy.
