Thanks to Mike, James, Gregory and Jim for your responses. I found a copy of the manual and learned that there is an OS disk required for startup. I didn't realize there were two different cables, one for the 100 and one for the 102. I was hoping it might be a standard cable, but I guess I'll be shopping at the Arcade, Gregory.
Yes, there is an RF interface as well as a composite, but I hate RF. I have a Commodore 1702 monitor that accepts a composite feed and I think that will work with this setup. James Z., the manual describes the disk-BASIC used with this device as a superset of M100 BASIC. I also read - on Wikipedia - that the TRS-80 Model 3 BASIC is different from that used in the Model 4. So that's four different "flavors" of BASIC within the product line of just one manufacturer. Can't assume all BASICs are the same. Jim, one man's "Trash-80" is another man's treasure. Good luck with your sale. Mike, thanks for your good wishes, guidance and contributions to the community. -CH-
