I myself have a Tandy 1000 HX. Intel 8088 (4/7MHz) processor, 128K onboard RAM +a 512K expansion card (640K total), MSDOS 2.11 on internal ROM, 2x 720KB floppy drives, CGA & EGA video onboard, 4-voice PC sound with headphone jack (Deskmate's music program was a lot of fun growing up.) The keyboard and PC unit were cobined, which made taking it apart interesting if you spilled something on the keyboard. It also had 2 propriatary joystick ports which in Deskmate could function as a mouse. Which I did xD This was my first computer (inherited from my dad). It's as old as I am, and it still works like a charm.
