To this day, people getting into retro computing are disappointed by the Tandy 2000 and other non-PC compatible MS-DOS machines. (I get it, having passed up on an AT&T 6300. But if you wanted to give me a DEC Rainbow or Zenith Z-100 I wouldn't say no).
I had a DEC Rainbow but I don't know who ended up with it. I also had a Sanyo MBC-555 which had quite good graphics considering but was very much one of the "almost-compatibles". Most things usually failed with the rather opaque "INTERRUPT TRAP HALT" message.
At first, I thought this was a well-written parody. I never had one inkling about this poem or his technical knowledge. I understand what he was talking about because I was around back then and understand and suffered from these gotchas.

Shout out to City Lights Bookstore in San Fancisco. I bought a lot of poetry books there in the late 80s and early 90s.
