I found this Discovery 500 on Ebay as a Local Pickup only. It came with quite a lot of equipment, plus there were a few other items in the sellers garage I picked up like that double power supply with analog meters and this [[REX Microcomputer System]] There is quite an extensive set of documentation and floppy disks. It has two Wy-50s that both work but only one keyboard.
