The Luxor ABC 800 series are office-versions of the ABC 80 home computer. They featured an enhanced BASIC interpreter, a slightly faster clocked CPU and more memory: 32 KB RAM & 32 ROM was now standard, the Z80 is clocked at 3.58 MHz (using an NTSC color subcarrier crystal). It featured 80 x 24 text mode with 8 colors. But they could also be extended with "high" resolution graphics (240 x 240 pixels) using 16 kB RAM as videomemory. The ABC 800 computer was also sold by Facit by the name Facit DTC. Each model appears to have the Intel 8035 controller in them for I\O.
