This is my original IBM Personal Computer in all its 4.77 MHz glory, now finally working again after two blown capacitors put it out of commission when I last tried it a year ago. I got this PC, including the original keyboard and IBM CGA color monitor, many years ago from the original owner, who used it as his work computer (it had the company's ID sticker on the case). Originally a 256K dual-floppy machine, I added more memory, a multi-function board, and a 20 MB Seagate MFM hard drive. Once I get the CGA video board working again, it will be restored to exactly how I had it a decade ago. Amazingly the original battery for the clock/calendar still seems to be keeping the time somehow! As far as I can tell, the NiCad "blue barrel" battery is original to the multifunction board (circa 1987-1988) and has never been replaced. I also give an example of how some classic DOS CGA games are *not* compatible with modern VGA video displays and will just show a garbled screen.
