Ok, both have a 50 MHz MicroSparc CPU, and both are therefore Sun4m 
machines. Both have 6 SIMM sockets and can take up to 96 meg of RAM in 
the form of 4 or 16 meg 72 pin 60 ns SIMM's.

Both are in a 'lunchbox' case, just like the IPC and the IPX, and they 
have room internally for one 3.5" floppy drive and one 3.5" hard drive.

The Classic (aka 4/15, or Sparc LC) has an on-board cg3 non-accelerated 
8-bit colour framebuffer, and single-channel 8 bit audio i/o. The LX (aka 
4/30) has an on board cg6 accelerated 8-bit coloour framebuffer, and 
two-channel 16-bit audio (courtesy of the on-board ISDN chipset).

The VRAM on the LX board can be expanded to allow you to use higher 
resolutions than 1152 x 900. To use the audio capabilities requires a 
speakerbox from an SS10 system, since it has a companion ISDN chipset, 
internal amplifiers, etc.

The LC has single-channel audio in/out on the back panel.

Both are rated at 59.1 SunMIP's, but the LX will appear to be faster 
because of the accelerated graphics hardware.

Both can be upgraded to high-performance Sparc-5 machines with 
replacement CPU boards from Cycle Computer.

Regards,

Craig.
