Retro Computing

Linux 7.2 is set to remove support for the Hercules Monochrome ISA graphics adapter, a move that closes the door on compatibility with one of the oldest display devices still acknowledged by the kernel. The change affects hardware that first appeared in 1982, making this a rare example of a modern operating system retiring support for a 44-year-old graphics card.The decision is not expected to affect ordinary Linux users. Instead, it reflects a broader cleanup effort inside the kernel, where long-obsolete drivers are gradually being removed when their maintenance no longer matches their practical value.A relic from the early PC eraHercules Monochrome ISA came from the dawn of the personal computer era, long before the term GPU became part of everyday technology language. It was built to handle graphics output on early PCs and occupied a meaningful place in computing history.Its technical limits underline how far graphics hardware has advanced since then. The card supported monochrome display output with a maximum resolution of 720 x 348 pixels and came with just 32KB of VRAM, later expanded to 64KB in a subsequent version.The adapter also used a horizontal frequency of 18.43 kHz, which was sufficient for early-1980s systems but far removed from the demands of modern desktop environments. By current standards, the hardware belongs firmly in the retro computing category.Why the kernel is letting it goAccording to Phoronix, the removal appears in a new merge for Linux 7.2 and is part of a wider cleanup of old hardware drivers. The Hercules adapter is included alongside other legacy components that have largely fallen out of practical use.Linux has long been known for keeping compatibility with very old hardware, but that approach has limits. Supporting a device that almost no one uses today means carrying extra code in the kernel, and obsolete drivers often become the first candidates for removal.The timing follows another notable kernel change in Linux 7.1, which ended support for i486. Taken together, the moves suggest that kernel maintainers are now more willing to draw a line under hardware that has outlived its relevance in modern distributions.Still a collector’s itemDespite the coming removal from Linux 7.2, the Hercules card has not disappeared from the market entirely. Some units still surface on eBay and are listed for low hundreds of dollars, showing that its remaining value is now mostly tied to collection rather than everyday use.When it launched, Hercules Monochrome ISA carried a $499 price tag. A later Hercules Graphics Card Plus, or HGC+, arrived at a lower $299 price point, making it a less expensive option in the same family.Those prices highlight how expensive graphics hardware could be in the early PC market. Today, the adapter stands more as a historical marker than a functional part of the Linux ecosystem, and Linux 7.2 will finally reflect that reality in the kernel tree.
