I had this comic book, it was a special edition sold at Radio Shack when I was a kid. And yeah that pocket computer was just a big calculator that had a lot of keys.
I had that computer, and it was much more than a calculator, unless you mean a modern programmable one. This one could be programmed in BASIC. It also had a receipt-sized printer you could get.
There was a book series called Micro Adventures that featured a kid named Orion who used a TRS-80. There were BASIC programs in the books that you could run if you had a TRS-80.
The first computers took up entire rooms and they could only do about as much as a calculator. There was a point in time that having a computer do multiplication and long division for you saved you hours of time because the alternative was have 2 or 3 people do it by hand and then compare to check for mistakes.
Some of the code cracking computers used for breaking war-time ciphers were state of the art, and their only job was to check as many combinations as possible, way faster than any human could. Which left the actual scientists to find optimizations and analyze any results.
Do you remember the Radio Shack comic? I think it was called "The Whiz Kids" or something like that. I had a few issues of that and felt like the coolest little nerd ever.
I'm imagining Superman's Krptonian family all arriving via their space pods to a family reunion where they, and the holograms of their parents, geek out over 80's human tech.
The stamp in the top right is the entire removable motherboard. I put my cardputer on a shelf when it got here and I haven’t gotten around to it yet. M5 stack is pretty cool, and I wish I understood it more.
I had one of these in grade nine! An uncle gifted me this calculator in my first year of high school. I was smart ... but not smart enough to know how use one of these or to realize that it might be a thing to keep. I used it for a year and it promptly disappeared after that.
The 8-Bit Guy has a nice video covering the functionality of a number of such devices. They're fascinating bits of kit -- they're like calculators you can type BASIC programs into. One of them can even be hooked up to a pen plotter to make graphs on paper -- it can even graph in 3D!
Tandy slapped the TRS-80 label on a lot of things that had nothing to do with the original TRS-80 design. The Color Computer line was marketed under that brand, for instance, despite being a completely different, incompatible architecture.
