John visited Kennett Classic to donate this nicely preserved Tandy Radio Shack TRS 80 Model 1 from 1978. His brother Bill was the original owner. The computer was purchased originally with Level 1 BASIC and was later upgraded to Level II BASIC. This was common back then, upgrades involved taking the computer into the local Radio Shack for service as there was no downloading of operating system patches like we have today. In this case an in-house technician would take the computer into the back room, open the bottom of the keyboard system unit to expose the motherboard. The technician would carefully remove the the Level 1 ROM chip from the motherboard and replace with a Level II ROM. Radio Shack provided a cassette tape with a program that could be used to update any Level 1 programs to the new Level II BASIC.
Karen spoke with John who (I believe) said of his brother that he worked in the semiconductor industry with Intel and also taught electrical engineering at De Sales.
