I could be mistaken, I believe there are two or three types of Mac +
motherboards. Post some key items that you could describe from your
motherboard, oh, you do need that 8" T15 or T20 screwdriver.
All of them requires working on either one jumper (yay) or move or
remove one resistor with soldering iron (boo hiss!).
Oh, also you need to check the ROMs for either one of 3 types. Type
1 and 2 require strange rule of starting up steps especially when
scsi devices are attached where Type 3 is most desireable. I
personally prefer SE/30 but no candy yet if the price is right! It
has: 8 simm slots, '030 at 16mhz, supports internal scsi hd and 1.44
fd. Just that board with ROM on it would do fine for me!
Mac Classic IS '020, 2 slot simm without most fancy enhancements like
that SE/30. :( The final but bit less desirable is the Mac Classic
II color.

System up to 6.0.8 can be run on that Mac + and SE, SE/30, and
Mac II models. 7.x is too demanding for them. When I was hired
at one of college working on inventoring, using Mac + 4mb, 7.x
and a database, slow SC hd, it seems does swaps every time I touch
keys. YUKKY! MHO.
