Installing one 512 kB and one 256 kB VRAM SIMM garbled the display.Дual-monitor configurations were only available using a rare discrete graphics card installed in the Quadra 605вЂ™s Processor Direct Slot.

The Quadra 605вЂ™s two available video RAM slots could take either two 256 kB 80 ns 68-pin VRAM SIMMs, or two 512 kB SIMMs. Video out was supplied by a single DA15F connector, which provided multiple resolutions with up to thousands of colors using the right combination of video memory. But after market SIMMs were also available in capacities as large as 128 MBs all of which could be used by the Quadra 605. The official supported maximum RAM was 36 MBs including the onboard 4 MBs.

But in order to make the 605 really sing, you would want to stuff its single 72 pin SIMM socket full of as much memory as you could afford. With 4 MBs of onboard RAM, the Quadra 605 was a usable machine under System 7.1. Of course the 68LC040 could later be replaced with a full 68040 which included an onboard FPU that tripled the speed of floating point operations. Running at 25 MHz on a 32-bit bus, it had 8 kBs of on-chip L1 cache divided into two banks 4 kBs for Data and 4 kB for Instructions.

You donвЂ™t have to be a Mac Genius to work on one.ДЄt the center of the 605вЂ™s logic board you will find the MC68LC040 CPU. The Quadra 605 was the easiest Macintosh to ever repair. Everything clips in or out all the way from the speaker & floppy drive, to the motherboard & power supply. The best feature however вЂ“ no screws on the inside. The entire top unclips in seconds, and inside every component is laid out in a plane вЂ“ nothing is above or underneath anything else, thereвЂ™s no remove-the-HD-before-the-motherboard-comes-out nonsense.

You wonвЂ™t find a reset, or programmerвЂ™s key on this Macintosh.Д®xactly what you need, and nothing you donвЂ™t. On the far right is the Quadra 605вЂ™s only expansion slot, the PDS. On the back you will find a rocker power switch, power connection, and the 605вЂ™s seven ports all lined up in a row. The Quadra 605 was a minimal Mac before its time. No plastic cover concealing a vacant drive bay. There is a slot for the floppy drive, a paperclip ejection hole, and thatвЂ™s it. On the machineвЂ™s face you will find the classic rainbow Apple logo, the word Macintosh, and the Quadra 605 name badge. The coolest thing about the Quadra 605 was its minimal design. Unlike the Cube, it was available for a low-price almost anyone could afford.ДЄt $900 USD, the 605 was the Quadra for the rest of us. Like the Cube it came in a low-profile case that was never used again on any Mac. A miniature 32-bit workstation, with limited expandability but powerful specs. The Quadra 605 was the Power Macintosh Cube of the Quadra line. Thomas writes at Egg Freckles, and is running in the St. This monthвЂ™s post is by my friend Thomas Brand.
