Someone had become frustrated at not being able to open the case and has drilled the tops off the bolts that secured the front of the clam shell, under the keyboard, so the top swings up fairly easily on the rear hinges to reveal a Ball TVX-12 CRT.
The circuit board itself is a sea of 74 series TTL, with the exception of the AY-3-1015D DUART.
Looks bad, tastes worse.
There is about 2mm of silicone-y stuff between the front of the CRT proper and another thick piece of glass, which is labelled as implosion protection. This rubber goo has now turned into a breeding ground for hard dry balls which, on a quick search, I see people refer to as cataracts.
In what is probably an ill-advised quest to have a clean screen, I’m pouring acetone onto the goo and scraping it out of the sandwich, *gently*!
