This is a Vintage NYSYS Desktop Home PC Personal Computer 3.5" Floppy Disk Drive Turbo Button.It is in great cosmetic condition with wear from use and age.The computer powered on, but the power supply sparked and the computer was shut down immediately. The power supply will probably need to be replaced prior to use. Power cord included.This came from a long time IBM Engineer who collected many of the items he helped develop over the years. Please see my other listings for more rare vintage computer equipment. Thank you!
