What is the speed of the SIMMS in the 030 and 040 NeXT cube? I need suggestions on obtaining SIMMS to expand my 030 cube, but I want to make sure that I will be able to use them on the 040 board! The NeXTcube and the NeXTstation require 100 ns SIMMs. Using faster memory will not improve performance, but is probably a good idea in planning for the future. The NeXTstation color requires different SIMM speeds and types. 2. Since the NeXT power supply adjusts to different voltages, would I need to connect a surge protector, or does it supply its own surge protection? It's never a bad idea to use a surge protector - after all, a $50 surge protector represents only 1% of a $5,000 computer system. Use one. 3. Is the Lotus Improv' promotion available to buyers who just got 030 NeXT cubes, or do I have to upgrade to the 040? It's available to anyone who purchases an upgrade to the 68040 board or a new 68040-based NeXT system. 4. Where can I find an implementation of a 9600 baud modem using the DSP chip? Does it exist? Not yet, though at least two companies are in the process of writing one. 5. Where can I obtain optical floppies? What do they cost? About $150 each. Try Businessland or a campus reseller. Or perhaps NeXTconnection. 6. I understand there was a problem with the optical drive getting too much dust from the internal fan, what resulted from this? What do I need to clean an optical drive? How often should I clean it? If I leave an optical floppy inserted in the drive, will it help reduce the dust problem? 68040 upgrades and new cubes come with dust filters, which should eliminate any problems. --- -------------------------------------------------------------------- Declan McCullagh / NeXT Campus Consultant \ declan@remus.rutgers.edu --------------------------------------------------------------------
