Here we go, but remember you aked.
I am a Tandyvision owner because my first computer was a Radio Shack Color Computer 2 in 1984 when I was 12 years old.
My dad was a regular customer of the RS stores and when it was time to buy me my first computer he naturally picked a Tandy (coco2 16k) product over the Commodores (64) that all of my friends were getting. I used this computer every day to learn BASIC and upgraded several time to where, by 1991, I was the proud owner of 512k Tandy color Computer 3 with dual drives, RGB monitor,and pretty much every add on that Radio Shack sold.
By 1991 I was in college and moved on to a PC, or more specifically a Packard Bell 386 SX running MSDOS
Fastforward to 2015
I found a RadioShack coco2 computer at a Value Village thrift store and the spark for Tandy was back
Over the next few years i picked up a coco1,coco2,coco3,model1,2,3,4, model 100,102,200, and several Tandy 1000's
Then I saw an ebay listing for a Tandyvision. What was a Tandyvision? I looked thru some of my old RS catalogs and saw that it was an Intellivision clone sold at RS stores. With the connection to my collection of Radio Shack computers I knew I needed to buy it,
We never had an INTV as a kid. We had an Atari 2600 instead. I tried out the Tandyvision 1 and was hooked. Soon I bought a Intellivision 1,2, and 3 because they were related to the Tandyvision which inturn was part of my Radio Shack collection. Then I found the system changer, for the INTV 2 as well as the ECS and musical KB. Then I found that there was a brown ECS and musical KB also so I got that for my INTV1 and Tandyvision.
Anyway thats how ended up being part of the INTV brotherhood
