Item Description:
TRS-80 Color Computer 3
Comes with rare AXX-7117 512K RAM upgrade board inside.
Also comes with 1 game cartridge - Super Pitfall by Activision
Tested via A/V jack direct to TV. Have not tested all connections so assume they need cleaning?
I'm not an expert on TRS-80 devices, but I cleaned some contacts and the picture was clear on A/V jacks.
Condition:
Coco itself needs retrobrighting and is dusty. Keyboard has scratches/needs cleaning. May need some type of restoration? Has rust spots in some metal parts.
Shipped with USPS First Class.
NOTE:
Follow my eBay account - I rescue stuff that often is headed for recycling or trash (plus some of my own collection) but each item you buy keeps it out of the landfill and in collector/tech-lover hands!
