.Quote from Spinnaker Software chairman William Bowman: "We're just sitting here trying to put our PCjrs in a pile and burn them. And the damn things won't burn. That's the only thing IBM did right with it - they made it flameproof." 
Mar. 1984, IBM ships the IBM PCjr.  It uses the 8088 CPU, includes 64KB RAM, a "Freeboard" keyboard, and one 5.25-inch disk drive, no monitor, for US$1300. 
Summer 1984, IBM introduces a new keyboard for the IBM PCjr, offering a free upgrade to all who want it. 
Mar. 1985, IBM announces that it will cease production and promotion of the IBM PCjr.
