The problem with it is that it is ahistorical enough in the tech that some things just don't work. The show tackles stuff about like a decade before it was actually relevant in market, and that has subtle problems that give the business stuff an uncanny-valley feel. Still a fun drama though.
I like the fact that it's the wrong years for the idea to succeed: Kind of like with the Newton, they are going into visionary ideas when the tech or the market isn't there. There's a lot of companies out there that fail because they go in too early to have good execution.
1000%. One of the big reasons I love Halt & Catch Fire is because their reach exceeds their grasp and they were too early for the ideas they dreamed of. I wrote a piece, partly inspired by the show, on category-defining products and how many factors have to line up for a product to become category-defining:
So many people have been there. Working to put something together, but with gaps that are hard to close. I have been there.
Even billionaires like Zuck bite off more than they can chew and flail around.
For that matter, Jobs at NeXT succeeded in an unlikely way in the end. But for much of NeXT's existence it chronically couldn't get enough traction. They ended up droping the hardware. Then down purposed their OS into a developer platform to run on other OS's. So disappointing. But they did such good work, when Apple had a need, they were ready.
And NeXT was the spiritual successor to Apple's internal "Big Mac" project which never even made it to market before it was killed. (The project leader Rich Page and others started phoning the already-fired Jobs, begghing him to step in, when Big Mac was deep-sixed.) The Mac had come after the Xerox Star, which failed commercially, and the Apple Lisa, which failed commerically: then it too nearly failed commercially, until the desktop-publishing market finally came together around it. And even then industry wiseacres like John C. Dvorak had years more fun mocking it (not completely without justification) as an extravagant toy and a market also-ran.
Of course Compaq was Houston rather than DFW. The case design for the first portable was scribbled on the back of a paper placemat at the House of Pies diner on Westheimer.
They still could have had Donna working at TI, which has a presence there.
During my first watch of this show there were around eleventy kabillion times that I reflexively shouted "that's not how that worked!" at the TV (and I'm a 90s kid with cursory retrocomputing knowledge). I say "reflexively" because I wasn't actually mad at these technical inaccuracies - they were largely in service of a good plot and weren't "SVU" or "CSI" levels of ridiculous.
So yes, those C64s were running software 5-10 years ahead of their time because the writers felt like it and were able to get away with such.
It also annoyed me that the Commodore 64s used for their online service were shown with DOS prompts. I think the set designers thought "Commodore 64s are old; old computers ran DOS; therefore Commodore 64s ran DOS"
Season 1 feels like its connecting back to Compaq, which made a competitor to IBM's PC platform. Founded by previous TI employees, reverse engineered IBM's BIOS, etc.
Correction: Season 2 is roughly about BBSs and QuantumLink (insofar as Mutiny is QuantumLink, anyway). Season 3 can be roughly summarized as "LOL, Norton".
Season 2 is roughly about BBSs and Compuserve, and still in Texas.
Season 3 is about the early commercial Internet, same characters, SFBA.
Season 4 is about the Yahoo era of the Internet and about venture capital, also SFBA.
