=== Disadvantage ===
{{expert|Computing|talk=Disadvantage|date=December 2023}}
A typical 8-bit monochrome card could turn the 16-bit 8 MHz ISA bus into an 8-bit 4 MHz [[PC bus]], which resulted in having the bus bandwidth cut by up to 75%. If the monochrome card was added to the PC as a second card besides a normal [[VGA]] card for debugging purposes, this resulted in slow VGA performance. Microsoft recommended in its ''Writing HOT Games for Microsoft Windows'' (1994) to remove the monochrome card in such a setup for maximum speed of the VGA card.<ref>{{Cite book |url=https://www.tech-insider.org/windows/research/acrobat/940929-a.pdf |title=Writing HOT Games for Microsoft Windows – The Microsoft Game Developers' Handbook |publisher=Microsoft Windows Multimedia |year=1994 |pages=17}}</ref>
