[A83] Re: What the heck is RST???
On the Silver Edition, the ROM pages are 00h-7Fh. Comparing my 83+ and SE
here, on the SE bit 7 is set for RAM pages instead of bit 6 on a normal 83+.
In summary,
the normal 83+ has ROM pages 00h-1Fh and RAM pages 40h-41h
the 83+ SE has ROM pages 00h-7Fh and RAM pages 80h-87h
