Macintosh Classic

You can get external video through the SCSI port for colour and some CPU upgrades. To quote LEM regarding the Macintosh Classic:

Accelerators

MicroMac Multispeed (16, 25, or 32 MHz 68030), optional 32 MHz 68882 FPU

MicroMac Performer (16 MHz 68030), optional 25 MHz 68882 FPU

MicroMac Performer Pro (32 MHz 68030), 64 KB cache, optional 32 MHz 68882 FPU

Discontinued accelerators (68030 unless otherwise noted) include the Applied Engineering TransWarp (16, 40 MHz), Dove Marathon Racer (16 MHz), Mobius (25 MHz), and Total Systems Gemini Ultra (33, 50 MHz).

 
Just be aware that if you install a Classic II board, you'll have to install 6.0.8L, rather than the regular 6.0.8.

 
Also be aware the ports are slightly different--you have a sound input jack on the Classic II (not present on a regular Classic).

 
While booting from ROM is handy if the OS won't boot, it's pretty much just a fancy feature. There's not much to in that booted state, what's the point? It's much cooler to have a personalized full system booting from the HDD.

 
That is pretty weird.. you all talk about drilling a hole next to the ADB port for sound in...

but on my Classic... there is already a hole there, including the microphone logo.

it is just covered with a little plastic cap.

That means they used the same bucket for the later classic I and newer classic II models.

funny thing to know, cause i didn't

 
Interesting in that my Classic does not have the plug but does have the molded information label instead of the adhesive label yours has. I can't remember ever having a Classic with a label like yours.

Maybe the plug appeared after the Classic II went into production.
