Wow! I'm so glad this actually did open the door from someone. I remember nerding out over how lame it was, but I was fortunate enough to have a TRS-80 Model III in my household. And I didn't fully grasp the hardware limitations then.
Someone really should DIY a real Atari "VCS," as in adequate bank switched RAM and something not unlike TRS-80 BASIC achieved without outlandish hardware for the time...
OMG! Someone pulled it off back in the day! I had no idea. So much for my retirement project idea:

That's ok, I have a lot of years to go before I need one LOL
