So if you inserted 8088 into V2 Book with VGA - that's the cause.

Crazy stuff - VGA is very clearly too much really. It was suggested to Pengain that they look at EGA max options but apparently the VGA chips are cheap and plentiful. It feels like the boards are rather untested though.
My only VGA success has been PETSCII robots at 320x200x8 (thats 256 colours). Nothing else.
There are many questions, why was a true Proton 2010 chipset not used and why a turbo limited to 8mhz...
