got it from ebay for 9 bucks+shipping. it has a 800k floppy drive and a 20MB HD. the mobo is dated 1986.
problem: it won´t boot. when turned on there´s no chime (but you hear the speaker clicking) and it´s displaying a sad mac. I tried swapping RAM and cleaning RAM slots and SIMMs. I pulled the ROMs and IWM and cleaned them but no chance to get it working. the PRAM batt. is still good. so...
any ideas anyone?
