Vintage Tech Archive: HVFULLSC – Full Screen Video Card and CPI Fonts 1.0 refers to specific, niche utility files preserved on retrocomputing repositories like the Internet Archive. These software pieces target vintage MS-DOS environments, specifically modifying video outputs and text-mode fonts. 🎛️ HVFULLSC (Full Screen Video Card Utility)
The HVFULLSC (Horizontal/Vertical Full Screen) utility handles display scaling and stretching on early PC systems.
The Problem: Many early retro laptops and graphics chipsets (such as older ATI Mobility or Chips & Technologies cards) did not display lower DOS resolutions natively in full screen. Instead, they rendered a small centered box with thick black borders.
The Solution: HVFULLSC is a driver or hardware-level TSR (Terminate and Stay Resident) software. It sends a firmware instruction to the video card to force nearest-neighbor vertical and horizontal stretching.
Outcome: It forces standard 320×200 (Mode 13h) or 640×480 resolution games and programs to fill up the entire physical screen or CRT/LCD panel. 🔤 CPI Fonts 1.0 (Code Page Information)
CPI Fonts 1.0 is a curated archival package of classic text-mode font layouts compiled into the historical DOS .CPI format.
Format Purpose: In the DOS era, screen and printer fonts were packaged into .CPI (Code Page Information) binary files. They are not vector fonts like modern TrueType files, but rather raw raster bitmap fonts built out of grid sizes like 8×8, 8×14, or 8×16 pixels.
What version 1.0 includes: This package aggregates system fonts extracted from prominent vintage computer families like IBM, Amstrad, and Tandy.
Usage: Retro enthusiasts use these with the native DOS DISPLAY.SYS driver and the MODE command (e.g., MODE CON CODEPAGE PREPARE) to change the look of the command line interface or adapt the PC to international language character maps (Codepages).
If you are trying to configure these tools on a specific emulator or a real retro PC build, tell me:
Are you running this on original hardware or an emulator like DOSBox? What video card or graphics chipset is your machine using? Which specific font or look are you trying to achieve?
I can provide the exact command line strings to help you set them up. The Ultimate Oldschool PC Font Pack – INT10h.org
