Collecting back when they were considered basically worthless junk by most people meant I paid no more than $30 for any one machine and most were actually given to me for free or shipping cost. I do have an Interact but it's one of the few I've never booted up as I never had one back in the day and being so obscure it wasn't one of the computers I lusted after but couldn't afford in the 80s. This article has inspired me to dig it out and fire it up. I heard from someone a few years back that apparently Interacts are quite valuable now due to their rarity (not that I'm in the market to sell any of mine).
As I recall, you don't flick the lighter you "flick bic" as was the marketing slogan at the time. The response would rhyme "flick bic" lead to "lamps lit". Other exciting things were using the paper tube from the bathroom and the lenses from somewhere else to "make telescope" which allowed you to read a distant sign or billboard.... Fun times.
Oh right, there's a shovel and if you "dig frog" the response was "I can dig it" because you know... the 1970's...
Do you have any good pictures of the tape? There's a Youtube video of someone playing it on hardware so you can see the tape inside of the machine, but no clear pictures of the real tape.
(Also, hello, I wrote the post! There's a part 2 where I finish the game, and I'll be doing the other Interact adventure game, Mysterious Mansion, in about a week.)
Modern attempts to build retrocomputers run into trouble being authentic because production runs are too small to justify an ASIC so they wind up using an FPGA or ESP32 for a display controller.
I would have probably got frustrated and started decompiling it to find all the verbs and nouns :/
