[features are 68020/030, 16MHz, 68881FPU, RAM, and price wishes]

When I was considering upgrading my Plus, I saw a great ad in the back
of MacWeek from Total Systems (99 W 10th Ave, Suite 333; Eugene Ore.
97401; (800) 874-2288).

The board is called the Gemini 020/030 and can work interchangeably in
128K/512K/Plus *and* SE.  It's a board that has sockets for BOTH
68020/030, 68881 OR 68882 math FPU, high-speed SCSI chip (no more of
this 1:5 or 1:3 interleave B.S. - 1:1 is where it's at!), 1 to 4 Mb
RAM (fast), built-in Video expansion, and utility software.

The utility software used to include a pgm to copy the ROMs into the
higher speed RAM on the board for quicker access.  Ram left on the
motherboard is accessable at the "top" of memory (e.g., as you fill up
w/MultiFinder, the last big application may run slightly slower).

I talked to the guys at length since they were the only ones who would
sell an accelerator board WITHOUT a CPU for a significantly less
money.  [I have a 68020 hanging on my wall from a 20Mhz workstation.]

The board can use the Virtual INIT, and they promise System 7
compatibility.  Note, however, it doesn't have a socket for a PMMU, so
you MUST use a 68030.

I decided not to upgrade since I don't use my Mac at home much anymore
and I wanted to SEE System 7 to see if it (sys 7) was worth it.
However, I'm sure I would have purchased from them -- they were very
knowledgeable and courteous and were willing to work with me.  The
board (8 months ago) cost around $800-$900 bare (w/o CPU, FPU, or
RAM).  I suggest you look at other vendors for lower cost chips
(especially RAM) for your specific needs.
