+--------------------------------------------------------------------------------------+ | | | The following is a document converted from Swedish. | | The Swedish document appears to have been created by Tomas Andersson in 1993. | | | | I modified it to account for two different versions of the card that I have. | | | +--------------------------------------------------------------------------------------+ Video7 VEGA VGA manual. VEGA VGA - Video Seven, Video7 - Compatible with VGA, EGA, CGA, MDA and Hercules, with its respective monitors (= frame rates). One will not see EGA on a CGA monitor, because CGA monitor can not handle the higher frame rate. - Analog display must always be connected to 15-pin socket; digital (TTL) display to 9-pin. - Memory: 256 KB Maximum Graphics Resolution: 800x600 16 solid colors Maximum number of colors: 320x200 256 colors from a palette 262,144 Max line/colum in text mode: 60line/100col or 43line/132col - Addresses: I/O = 3B0-3DF Video RAM = A000-BFFF Video ROM = C000-C7FF IRQ = 2 (IRQ 2 should not be used by anything else in the computer, according to the manual.) .-.--P4P5---J4-----J8------------. .-- | : : :::::::: ---- 6+-| | SW1:1-6 | .-.-.-.-. .------. | | | 6-pin DIP | |-|-|-|-| P1 |Video7| 1+-| | | '-'-'-'-' : |GD410 | .====. | '------' | | 15-pin | Copyright P8: | | mini d-sub | 1987 P2-- ==== | P6: | | | .------. .-----------. .====. |J6 |Video7| |435-0016-47| | | 9-pin d-sub | . |GD420 | '-----------' ==== | : '------' :P3 | | '--------+ +---' | |___________________| | .-.--P4P5---J4-----J8------------. .-- | : : :::::::: ---- 6+-| | SW1:1-6 | .-.-.-.-. .------. | | | 6-pin DIP | |-|-|-|-| P1 |Video7| 1+-| | | '-'-'-'-' : |GD410 | .====. | '------' | | 15-pin | (c)1988 P6: | | mini d-sub | 650-0095 P2-- ==== | | | | .------. .-----------. .====. |J6 |Video7| |435-0019-47| | | 9-pin d-sub | . |GD420 | '-----------' ==== | : '------' P7: :P3 | | '--------+ +---' | |___________________| | ---------------------------------------------------- SW1: 1-3 Monitor/Display type SW1:1 1:2 1:3 Auto-sensing, auto-switching (default) OFF OFF OFF NEC Multisync, Nanao8060/9070, Princeton UltraSync ON OFF OFF Sony Multiscan, Mitsubishi, Taxan Thomson OFF ON OFF NEC Multisync Plus, NEC Multisync XL ON ON OFF IBM PS / 2 Analogue display, or equivalent OFF OFF ON IBM Color Display (CGA), or equivalent ON OFF ON IBM Enhanced color display (EGA), or equivalent OFF ON ON IBM Monocrome display (MDA, Hercules), or equivalent ON ON ON ---------------------------------------------------- SW1: 4 Primary / Secondary OFF = Primary (default) ON = Secondary Two monitors can only be used if one is CGA and the other is MDA (or Hercules 32KB). The VEGA card is set as Secondary so it adapts to existing cards. ---------------------------------------------------- SW1: 5 Autoswitching ON = Autoswitching On (default) OFF = Pure VGA mode OFF is required for those times when the card must behave as a standard IBM VGA card (e.g. OS is OS/2). ---------------------------------------------------- SW1: 6 Initial boot fashion OFF = Restart in VGA mode (default) ON = Starts in CGA/Hercules-mode (depending on SW1 :1-3) ---------------------------------------------------- P1: EGA 2XX/3XX address port Default is pins 1 & 2 bridged (i.e. use I/O ports 3B0-3DF). ---------------------------------------------------- P2: ROM enable Pins 1 & 2 are bridged to enable the ROM (default) Pins 2 & 3 are bridged to disable the ROM ---------------------------------------------------- P3: XT slot 8 By default, pins 2 & 3 are bridged. If the VEGA VGA card is installed in expansion slot 8 of the IBM XT, then bridge pins 1 & 2 instead. ---------------------------------------------------- P4: Feature oscillator By default, pins 2 & 3 are bridged. If another card connected to feature connector J4, then bridge pins 1 & 2 instead. ---------------------------------------------------- P5: Reserved jumper Will never change. Must have pins 2 & 3 bridged. ---------------------------------------------------- P6: On one version of the card, P6 selects ROM Size (P6 is labelled 'ROM' and '16K' and '32K'). Pins 1 & 2 are bridged for a 16K ROM Pins 2 & 3 are bridged for a 32K ROM (default) On another version of the card, P6 is associated with monitor type (P6 is labelled 'CD/MD'). Default = Pins 1 & 2 bridged Pins 2 & 3 should be bridged if an MDA / Hercules or CGA monitor used. This grounds pin 2 on the 9-pin d-sub connector. Pins 1 & 2 are bridged for all other monitor types (EGA, VGA, etc) ---------------------------------------------------- P7: At least one version of this card does not have a P7. On one version that I see P7, P7 is labelled as 'INTENA', which is sure to be short for INTERRUPT ENABLE. Pins 1 & 2 are bridged to enable interrupts (default) Pins 2 & 3 are bridged to disable interrupts ---------------------------------------------------- P8: At least one version of this card, P8 selects ROM Size (P8 is labelled '16K' and '32K'). Pins 1 & 2 are bridged for a 16K ROM Pins 2 & 3 are bridged for a 32K ROM (default) ---------------------------------------------------- Software included: MONFIX.COM For games that use non-standard CGA modes --- Tomas Andersson 1993-10 -
