Lengthy Earlier than NVIDIA’s GeForce RTX 5090, There was the Hercules Graphics Card

Companies within the early Nineteen Eighties had been all about paperwork and figures. Spreadsheets had been merely rows of figures, paperwork had been heaped up web page after web page, and IBM PCs had been the workhorses that dealt with all this information, with an choice of two displays. IBM selected Coloration Graphics Adapter, which offered a splash of shade however was solely 640 by 200 pixels, making textual content seem blocky and tough to learn. Then there was the Monochrome Show Adapter, which produced a 720 by 350 pixel display in a transparent inexperienced or amber. Hercules Pc Expertise recognized the hole and stepped in with a card that married each strengths with out having to make any sacrifices

Founder Van Chu arrived from Taiwan with a wealth of technical data and a transparent imaginative and prescient of what he meant to realize. His staff created the Hercules Graphics card to suit straight into present MDA techniques. Customers can preserve their monochrome displays and nonetheless have management over pixels. In graphics mode, the system managed 720 by 348 pixels, which got here near matching MDA textual content high quality whereas additionally permitting for early drawing and simulations. A 32k body buffer contained your complete display, permitting functions to write down on to video reminiscence whereas holding the CPU free to carry out precise work.

The {hardware} conveyed the state of affairs fairly clearly: the preliminary MDA card had 8 kilobytes, which was sufficient to deal with plain textual content pages. Then Hercules got here alongside and doubled it to 64 kilobytes, divided into two banks. The issue was that video games solely used half of it as a result of they may solely show black or white pixels. A parallel port sat on the bracket, replicating the IBM design, making it easy to improve. Quickly after, corporations started producing clones that might run alongside the Hercules on CGA modes through DIP switches. ATI joined the celebration late within the decade with some hybrid boards, however the unique playing cards maintained their popularity for purity.

Software program builders had been desperate to leap on board, with Lotus 1-2-3 introducing charts and high-quality strains. The framework described paperwork in some depth. Dr. Halo created technical graphics one pixel at a time. Video games started to appear in waves. Microsoft Flight Simulator 3 succeeded to make cockpit gauges appear sharp sufficient to learn. SimCity set out cities block by block, eradicating the unattractive jagged edges, whereas Prince of Persia managed to make animation look easy on monochrome screens. Apparently, there are 536 titles that natively assist Hercules graphics, which is significantly behind CGA however nonetheless quantity to show there was a requirement.

The frosting on the cake was the usage of twin displays. MDA reminiscence was mapped to deal with B0000, whereas CGA was assigned to deal with A0000. So long as you put in each playing cards and related separate screens, code flowed seamlessly throughout them. Programmers might full their monochrome code whereas checking shade output on a second monitor. Although monochrome had lengthy since gone out of vogue, this configuration was nonetheless fairly prevalent in VGA days.

The Graphics Card Plus, launched in 1986, was Hercules’ most bold product. Some of the spectacular points was how they managed to suit the entire similar performance right into a smaller chip whereas additionally including some further RAM for a bespoke character font. Software program might now redefine characters on the fly, a characteristic that Commodore customers had lengthy loved however PC prospects had only recently caught up with. When it comes to actual reminiscence, not a lot modified (64k was nonetheless the utmost), however the whole lot turned a little bit extra compact, which helped to save lots of bills whereas additionally making certain that the whole lot labored correctly.

Home windows 3.1 debuted in 1990, exposing the constraints of CGA, and it appeared fairly horrible. The menus had been squeezed right into a tiny 640 by 200 pixel house, and the Solitaire playing cards had blurry fits. However hey, Hercules managed to attract your complete interface at full decision, which made an enormous distinction: the icons had been stunning and crisp, and the textual content was clear. Solely the colour cues needed to go; purple hearts and diamonds required people to recall how the deck appeared.

Coloration tempted Hercules as soon as extra, however they lastly acquired there in 1987 with the InColor card. This one maintained monochrome compatibility whereas including 16 colours from a 64-color palette at 720 by 348. EGA displays had been shut sufficient to sync, and 6 video games supported the mode – although, to be trustworthy, Deluxe Paint didn’t trouble with it and solely used two colours. Sadly for Hercules, the market was already saturated by EGA and VGA when the InColor card was launched.
