I have just added a MicroNet MP-46 (Seagate 157N drive) to my relatively
new MAC+ (5 months old). I opted to use the floppy drive cable power
supply as it was cheaper:-) The question is as follows:
1) What is the MAC+ power supply capable of delivering (watts)
2) What is the demand (watts) on the supply from the MAC+ itself
It seems to work ok except that the drive does not become ready fast
enought to boot off it upon powering up. I must still press the reset to
get it to boot. With all the horror stories on the net about the MAC+
power supply I wonder if I did the right thing. Any comments?

Quote from Inside Macintosh volume III, pg 33: "Warning: This connector was designed for a Macintosh 3 1/2-inch disk drive, which represents a load of 500 milliamps at +12 volts, 500 milliamps at +5 volts, and 0 milliamps at -12 volts. If any other device uses this connector, it must not exceed these loads by more than 100 milliamps at +12 volts, 200 milliamps at +5 volts, and 10 milliamps at -12 volts, including loads from all other connectors combined." I have a Quantum ProDrive 80S (8 watts) powered from this connector, works like a dream. I did have to re-solder the flyback transformer and connectors on the video/power supply board. This doesn't have anything to do with using the PS to drive the winnie. -- Real life: Thomas Tornblom Email: thomas@uplog.se Snail mail: TeleLOGIC Uppsala AB Phone: +46 18 189406 Box 1218 Fax: +46 18 132039 S - 751 42 Uppsala, Sweden
