I’m doing a bit of retro computing at the moment, having purchased a very good TRS-80 Colour Computer 2 (or coco for short). It has extended colour basic licensed by Microsoft (1981) and 16K of RAM. Yes folks, sixteen kilobytes of RAM. I’ve purchased a data cassette player to match (hasn’t arrived yet). I’ve tried loading a few programs from the PC to the coco via the cassette cable but have had only limited success. I’ve ordered some 4 pin DIN plugs to allow me to make up a suitable serial cable so I can send/receive data over serial to the coco.
These computers hooked up to your tv set via the aerial socket, no separate video/sound output. As you can see from the picture, the display on the screen is a bit fuzzy. Not sure why yet, perhaps the cable is no good or the socket is dirty or out of alignment. In any event, I’m having some fun re-living the early home computer years with my coco and its really testing my memory on BASIC programming.
Update: I’ve recently purchased a TRS-80 Model I, which is really the ‘Model T Ford’ of the computing era. Here’s a nice article about them on CNN.
