Cassette BASIC
You can access Cassette BASIC even if the diskette drive is present by simply leaving the drive empty. This is true on the PC AT and PS/2 models as well simply by pressing F1 (provided the fixed disk is not present). Joshua 17:12, 9 December 2005 (UTC)
"The keyboard scan codes are different"
I think something else is different, because with XT keyboard plugged in AT (or the opposite) you get NO KEYBOARD INPUT when you press keys, instead of wrong keyboard scan codes.
That means, something other differs - probably the whole protocol of data exchange
- There's also the A20 gate control in the AT keyboard.
Another difference from the PC
The XT's ISA bus slots are closer together than the ones in the PC. That makes old PC cases physically incompatable with XT or AT or any later motherboards, all of which to the present use the exact same slot spacing as the original IBM AT.
Photo
Has anyone got a better photo? I haven't got an XT myself so I can't take care of that.
- I added a better quality photo of an XT with a vintage touch. I also made the original color photo available through Wiki Commons, under Ibm_px_xt_color.jpg, if that one is preferred. Rderijcke (talk) 23:38, 24 February 2008 (UTC)
- I was so bold as to replace your b/w image with your colour image in the article. Thanks for both. :) 86.56.122.190 (talk) 20:13, 9 June 2008 (UTC)
