That's correct. The system detects the VRAM amount and disables screen 7 and 8 if you only have 64kB.
But there's a much easier way: the BIOS prints the amount of VRAM on the screen at start up. And that's not a fixed string, it's actually detecting and reporting the found VRAM.

Isn't that a bit weird, one screen 7 or 8 page taking only 64KB VRAM? They could have allowed the screen 7 & 8 instructions and just disable SET PAGE for values > 0 ?

This is necessary because each VRAM bank doesn't have enough bandwidth to supply the data to the raster. The VDP then alternates one byte for each bank, doubling the effective bandwidth.

With 64KB of VRAM, there's only one VRAM bank, so it's not possible to have any of the screens that have 64KB pages.

MSX Gids issues scanned so far:
https://1drv.ms/f/s!At2URH9aT-e6iJBAdkkTquaCKoxuJQ

Right now this should match the list on archive.org. I've noticed one difference and that's that the PDF I have of MSX Gids 13 isn't watermarked (it seems to be the same otherwise).

I don't know who manages the "msx-manuals" uploader account on archive.org, but if you're reading this:
If I manage to add new ones, do you prefer to add them to archive.org yourself or do you rather have me uploading them?
You can contact me at samor-at-live-dot-nl if that's preferrable.

...speaking of which, is there an archive of "MSX Info" yet?

@Samor: Unfortunately not, I would love that. I used to have them all, but then I gave them away when moving. I can't hit myself enough against the head Sad
