IF you are not using the +12V line to drive a floppy disk, this PSU should be OK for most medium size S100 bus systems. RS232 drivers really don’t sink that much current. Older LSI/MSI chips even less. John From: Frank Schieschke [mailto:f.schi...@googlemail.com] There is also a dual +/-15V Meanwell PD-2515. http://ca.mouser.com/ProductDetail/Mean-Well/PD-2515/?qs=V9a8iPeg90wj6pKOH0Z1PQ== |
