Macintosh Quadra 650
Quadras were known as high-end Macintosh computers. Quadra 650 contained a new, 68040 CPU, had SCSI and AAUI - an advanced network interface which allowed to connect Mac to any existing network if the proper adapter is supported. Quadra had 16-bit graphics at 640x480 - a standard used by QuickTime. 24-bit TrueColor standard was known, but not so commonly used these times, so 16-bit was maximum for this model. Memory was expandable to 136MB using 128MB in SIMMs and with 8MB on board. Some units had only 4MB, these were usually equipped with ROM SIMM slot too.

My unit is saved from recycling. It has been extensively
used in some magazine editorial, but it is in quite good shape (except
floppy drive which has problems pushing some floppies out).
