Kroc Camen@atomicpoet Slides into the seat next to you and opens my Psion 5mx with its award-winning smooth hinge mechanism. Its 48MHz ARM chip is both powerful and power efficient, the whole device can run for 20 hours on just two AA batteries. The keyboard is full-travel and despite its size, it provides the best typing experience for a palmtop computer, bar none. The screen is a stunningly high density 640x240 pixels with 16 shades of grey and an electroluminescent backlight sandwiched along with the touchscreen. I press the side of the device and the stylus cooly springs out from its integrated spring-lock storage. This is a portable writing and calendaring battlestation and it has never been beaten in 25 years.

gloriouscowThe latest additions to the PC Emulation Book:
A reference for the BIOS Data Area

IO port reference for common PC/XT/AT hardware
https://book.martypc.net/appendices/io-ports
A handy reference for CGA/EGA/VGA palettes

I've also started documenting the EGA register file, since I've been all up in the EGA recently.

An EGA-specific reference will be handy as if you've ever wanted to emulate an EGA you often find yourself sorting through VGA references and removing all the VGA specific bits.
What's this? Oh, this is just everyone's favorite EGA card, the Tseng Labs ET2500.
What do you mean you've never heard of the Tseng Labs ET2500?
