Hi. Can anyone post or send me information about the largest hard drives that will fit into a IIsi? I know that a 1/2 height supposedly will fit, but that there may be gotchas with respect to power consumption if I also use a 24-bit color card or an accelerator at some point. The largest 1/3 height drive I've heard of is the Quantum 105LPS. Is Quantum going to come out with larger 1/3 height drives, or, alternatively, are there larger 1/2 height drives that don't use too much power? Scott sburke@jarthur.claremont.edu

In EE Times, Quantum is advertising a new range of 3.5" drives and 2.5" drives. The 3.5" drives come in 80 and 160 MB capacities, and are smaller (both in length and height) than their existing 3.5" drives... These advertisements look like pre-announcements though. I don't know how long it will be before they're readily available. -- ------------------------------------------------------------------------------ Evan Torrie.

Apple GROSSLY underpowered the power supply and has been the cause of a lot of 'accidents' with adding peripherals and third party items that draw too much power. As far as graphics and accelerator cards - just remember that whatever card you purchase, it cannot use over 15w - that's all the power the si can spare to the NuBus. BTW - Did you know that the 8.24GC uses about 20w. Apple can't even make machines that work with their own hardware. Blacksheep Senior Systems Engineer -- Darrin R.

OK, I've heard enough about this. The Commodore Amiga 500 has a -very- small power supply. Between the virtually mandatory 1 meg expansion board, and an external drive, there is little to no power left over for other uses. However, alternate power supplies have been produced for the 500 - although is is somewhat easier for the 500 as it's power supply is external The point to all this is - has anyone considered the possibility of beefing up the IIsi's power supply? Can any hardware person out there tell me that it's either impossible or not feasible or horribly expensive to do this? -- Jim Gaynor - Systems Analyst 1 + "This is Serious. He is Lost.

You mean ripping the internal drive out and replacing it with an external might be an alternative to "beefing up the IIsi's power supply"? -- Philip Machanick philip@pescadero.stanford.edu

It would be economically unfeasible to buy a NuBus expansion chassis in order to expand an Mac II SI. Expansion chassis are EXPENSIVE, and it would make more sense for you to buy a Mac II CI with all the NuBus slots you will probably need. It would be cheaper to get the external unit for the SI with it's own external power supply than to go the NuBus route. Apple designed the II SI for those folks who don't need the NuBus expansion (although you have the option of installing a NuBus Adapter if you need one). As for cracking open a Mac SE, it's no great problem. There are four screws holding it together and the case snaps apart. Although room in kinda tight, it doesn't take much effort to install/replace disk drives. You have to give Apple credit for the way the machine is put together (non-ergonomically speaking). -- Greg Fabian ////////////////////////////////////|\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ CTI (703) 685-5400 | 2121 Crystal Drive | When the going gets weird Suite 103 | the weird turn pro Arlington, VA 22202 greg@cti.com | - Hunter S.
