Is there anybody out there who could give me some details on the new Mac LC, the new machine is what I hope to purchase (I don't own a MAC at the minute) but this machine seems to be left away from the light by the computer press in this country. Some questions about the machine... does it come with a monitor (I hope so)? is it expandable (I heard that the classic is very limited)? does it come with an 8bit or 24bit graphics card? what is its compatiblity like? (I think it is the only mac to use the 68020 chip is it not) Thanks in advance. -- * _____ _ * Real Name: Raymond Hayes * * / ' // * JANET: csh003@cck.cov.ac.uk * * ,-/-, __. // _. ______ * Quote : To be intoxicated is to feel * * (_/ (_/|_</_(__(_) / <_ * sophisticated but not be able to say it *

Though, there is a new monitor (12", RGB) designed for the LC. It lists for $599. The problem in the area of monitors: - The 12" Monitor displays something like 512 x 384 pixels (64 dpi). This is similar to the Mac plus/Classic. However, the monitor was designed with the LC in mind, and as a result, can display 256 colors (LC's 8-bit on board color) with no modification. If you obtained the 512k "VRAM" (Video RAM), the number of colors would increase to 32,768, I believe. - The 13" RGB Monitor has a resolution of 640 x 480 (72 dpi). However, this monitor existed before the LC, and because of some bizarre reasons resident in the LC, this monitor can display only 16 colors (4-bit) if connected to an LC. If you buy the VRAM, you can get 256 colors. The list price on the 13" RGB is $999. >is it expandable (I heard that the classic is very limited)? > Yes, mildly. It does not have a NuBus slot. It has what is referred to as a "Processor Direct Slot." This is a slot specifically designed for the LC's 68020 cpu. There is a NuBus adapter that will allow those type cards to be installed (only space for 1 card). There are a number of companies that are designing boards for that slot directly (not assuming the buyer has a NuBus adapter). One such company has a 68040 accelerator board out for the LC! >does it come with an 8bit or 24bit graphics card? > 8-bit color built-in. >what is its compatiblity like?

The system software for Macintoshes will run on all Macintoshes, though not all of them can take advantage of all of the features in System 7.0, for example (virtual memory). Compatibility, I think, is not an issue. ============================================================================== BRANDON G.

If you buy the VRAM, I didn't think the reason was so bizarre. Isn't it a matter of the amount of video RAM on the motherboard? >a "Processor Direct Slot."

There are a number of companies that I don't think the LC supports NuBus, even with an adapter.

Apart from the fact (obvious :-) that the Monochrome 12" won't produce any-bit 'colour', the implication is that the 12" mono screen has the same pixel count as the 13" AND can support 256 grey scales. This is something I really have to know for certain, since I am considering buying the Si, and would go for the 12" mono monitor if it offered 256 greys (after all it is extremely cheap, and I'm not really interested in colour). Can anyone be definitive about this? What's the supply situation of 12" mono monitors like at present?

The new Macintosh 12" Monochrome Display (M0298LL/A) will display up to 256 shades of gray simultaneously and 640x480 pixels (76 dots per inch). It is my understanding that this monitor is to replace the old monochrome monitor. Until production ramps up for the new monitor (or, perhaps, until stocks of the old monitor are depleted) the old monitor was selling for the same price as the new monitor (if I remember correctly).

I'm using the new 12" monochrome monitor with a 4-bit card upgraded to 8-bit (did you know that this only costs about $25-$30 to upgrade via mail order?) on a IIcx. I prefer this over the new 12" color monitor which costs twice as much and has poorer resolution. There's something to be said for color, though... -Ralph

Also, I believe that monochrome displays are sharper than color displays even if both have the same resolution in terms of dpi. One more possible advantage to monochrome displays is that I believe they have lower emissions than color displays, and represent less of a potential health hazard (if you believe in this stuff). Is this true? -Ralph

I am on the verge of buying a LC through my university. I have heard rumors that a 68030 version may be out soon. Could anyone give me some advice on whether I should wait to get it? I also would appreciate information on adding a FPU to it. Any other comments or criticism of it would be appreciated. Thanks, Jed Wright
