GIGABYTE Announces its First Intel H81 Chipset Motherboards@ 2013/07/26
The H81M-DS2 has a focus on legacy connectivity, which could go well with POS (that's point-of-sale, but we won't disagree with what you made out) PCs that are wired to old LPT printers. Its legacy ports include an LPT parallel port, an RS232 COM serial port, separate PS/2 ports for mouse and keyboard. Its lone display output is a D-Sub (VGA). The H81M-D2V sheds LPT while retaining a the RS232 COM port, and a slightly more modern display connectivity that includes D-Sub (VGA) and DVI. It features a single, common PS/2 connector. The H81M-D3V has the least legacy connectivity, with just DVI and D-Sub for display outputs, no rear-panel COM or LPT ports, and a common PS/2 connector.
