There are two versions of Ultima 1, the original has BASIC is basic with assembly and there is a remake in pure assembly. You can definitely tell the improvements the asm version brings with the overworld scrolling faster and the first person dungeons redrawing very quickly.

So - I'm guessing game logic of MECC Oregon was in Basic with some assembly routines to re-draw the screen. BTW original Oregon Trail was also 100% basic and a PITA to read. You're really getting to the edges of what applesoft basic is practically capable of with games like Akalabeth and Oregon

That reminds me of finding out Sid Meier's Pirates! on the C64 was a mix of BASIC and assembly. You could LIST a lot of it, but the code was full of SYS calls to various assembly helpers, which I remember was incredibly frustrating as I did not yet have any idea how assembly worked so it felt so close but so far to being able to modify it.
