    I haven't had any real problems running any software for the Mac II
family on the LC in my office, especially if you install the Pseudo-FPU
init, but if you have a coprocessor expansion card then you will
definately have no problems. In terms of the extra VRAM SIMM, this is
pretty much icing on the cake, but it does make certain programs look a
lot nicer.

> 2. Does Mac II software require a 68030 or just a FPU?

    As far as I know, Mac II software doesn't necessarily require
either of them, but yes most software thatr is written for the Mac II
does look for a co-processor. I don't think that it actually looks to
see if you are running a 68030 CPU.

> 3. Does an LC with VRAM do full 8-bit color on the Apple 13" monitor?

    Yes it does, and I have always felt that the main reason to get the
VRAM upgrade is because you have a 13" monitor with your LC and you
want more than 16 colors. I have always hated the 12" color.

> 4. Are there any boards for the LC that have a FPU and a PMMU?

    I believe that there are a couple of them, I seem to remember
reading an add for them in MacWeek. This is the place to check. Chances
are if it exists inthe 3rd Party world then there is an add for it in
the back of MacWeek.

> 5. Has anyone had any compatibility problems with the LC?

    To be honest, in the 4 months that I had an LC the only thing that
ever gave me a compatibility problem was trying to use the Satori
module with AfterDark because it required a Math Co-processor. Later.
