Hi, I'm in the process of convincing myself to buy a TT, and I'm stuck with the following questions: As I'm told the TT does not have a 68882 on board, but does have a socket for such a beast. Right? What speed must this beast have, or can is the speed selectable? the 68881 and 68882 are supposed to be compatible. I owe a 68881. Can I use that one instead (assuming it is the right speed). I'm a little puzzled by a previous posting about how memory is implemented. Are there two different daugtherboards?? If I buy a 2 MB system is it then just a case to add sims if I want to upgrade to 4 MB? If not, I think I'll prefer to buy a 4 MB system. Is such a 4 MB system easily upgradable (e.g. by adding (or maybe replacing) simms). From a previous posting I concluded that there is a different daugther board if you go to 8MB. Is the ram on the second daughter board faster than on the first one?? What speed is the ram actually. Do I get wait states when accessing the memory? In any of the above cases?? Then there is the monitor. Is it possible to use an ST monitor if the screen is in an ST resolution?? I think the price on a TT monitor is on the high side. However, I'm told that this is just a regular VGA monitor. Can I go out and buy a VGA monitor and use it? I assume I need a monitor with 640x480 resolution and 60 or 70 hz refresh rate, and a D connector plug (forgotten the number of pins). Do I need a color monitor, or can I also use a monochrome monitor. Using a monochrome monitor would cut the price with $ 200 or $ 250, and I do not really need color. If someone could answer these questions that would be very appreciated. Thanks! -- Frans Meulenbroeks (meulenbr@prl.philips.nl) Centre for Software Technology

Right? No the 68882 is standard (however, it may be in a socket...?). >What speed must this beast have, or can is the speed selectable? >the 68881 and 68882 are supposed to be compatible. I owe a 68881. >Can I use that one instead (assuming it is the right speed). The 68882, like the 68030, runs at 32 MHz. >I'm a little puzzled by a previous posting about how memory is >implemented.

From a previous posting I concluded that there is >a different daugther board if you go to 8MB. Is the ram on the >second daughter board faster than on the first one?? Ok. The two basic memory types are ST and TT ram. ST ram is located on the mother board (I believe that there is 2MB soldered and 2MB socketed which are empty if you get a 2MB TT or a 4MBTT with 2MB TTram) and doesn't need a daughterboard. TT ram does need a Daughter board (its more than just a bunch of SIMM sockets - it also has a chip that allows access to the TT memory). The TT daughterboard holds 4 SIMMS - up to 16MB max (using 4MB SIMMS). Using the card slot inside the machine, you can add a memory board for even more memory. However, in neither case is it simply a matter of slapping SIMMS into your machine (unless you already have the TT daugterboard). > >What speed is the ram actually.

Since the machine runs at 32MHz, I assume that there are at least 1 wait state on all memory, the TT ram having less than the ST ram. > >Then there is the monitor.

No. Even though the TT displays ST resolutions, it does it on the same signal that displays the TT's special resolutions. >I think the price on a TT monitor is on the high side.

I can't see why not (except you may need to "customize" the cable connector). >I assume I need a monitor with 640x480 resolution and 60 or 70 hz >refresh rate, and a D connector plug (forgotten the number of pins). >Do I need a color monitor, or can I also use a monochrome monitor. >Using a monochrome monitor would cut the price with $ 200 or $ 250, and >I do not really need color. I forget - is 640x480 the max resolution of the TT's color screens? If not, you will need to get a monitor that reflects that limit. > >If someone could answer these questions that would be very appreciated. > >Thanks! >-- >Frans Meulenbroeks (meulenbr@prl.philips.nl) > Centre for Software Technology Hope that does it! -Mike
