Double CGA Display in Olivetti Quadero

  • by

Although 640×400 (“double CGA”) LCD screens usually could display only “black” and “white” (so the 320×200 4-color mode was handled using multiple 2×2 1-bit patterns) this was an exception. The screen on Olivetti Quaderno can display four shades of grey with a good contrast. It reminds me playing games on old Game Boy handhelds…

MS Flight Simulator 3.0 on Quaderno

  • by

MS Flight Simulator 3.0 running on Olivetti Quaderno PT-XT-20. Although only XT-compatible, 16-MHz NEC V30 is five times faster than original PC with 4.7-MHz Intel 8088. This means that the game is perfectly playable on this machine.

The internal 20MB Conner hard-drive is defective and needs to be repaired. However I am able to share a hard drive from another computer over a provided null-modem serial cable thanks to somebody in Olivetti who decided to add interlnk.exe and intersvr.exe to the C: ROM drive.
