I hope that this is marginally on topic - the technology is over 10 years old and it is about using an old machine even if the OS is brand new. I have a PS/2 Model 30 and am taking part in testing the ELKS port of Linux to the XT architecture. On the PS/2 ELKS cannot see any keystrokes, having booted OK. Does anyone (Tony?) have a techref for this machine and if so what is the difference between this and a 'normal' XT. I am thinking that perhaps the keyboard buffer may be at a different place in memory thus DOS, using the BIOS, can see it but we can't by looking directly at the hardware. TIA Pete
