Board part numbers. Can anyone confirm? I have a IIvx but its has a -B board. So wondering if swapped. If anyone else has a IIvi or IIvx and can post board part numbers that would be cool.
Well I decided to open it up further. Mine has an 030 at 33Mhz with an FPU. Good! So that is spec for a IIvx. Wonder why Apple advertised it at 32MHz?
So my guess is -A came out for IIvx. Then -B was a revision which was used for the:
IIvx (32mhz 030 with FPU) (replaced -A board)
IIvi (16Mhz with no FPU)
Performa 600 (32mhz with no FPU)
The ones with no FPU seem to have had a socket to add one. So this makes more sense, -B might be a more "universal" board to accommodate the 16Mhz 030?
Forget that, found a -A board with an FPU socket which is captioned for a Performa 600. Oh well. Guess just a weird plethora of whatever Apple felt like doing... LOL
Apple advertised as 32 MHz because they went 'cheap' and used a 16 MHz chip to generate the clock for the CPU, doubled to 32 MHz on that model; even though the CPU itself was rated for 33 MHz.
