It was Hewlett-Packard's most ambitious desktop computer to date. The HP 9845 A had two 16-bit hybrid microprocessors-one for language processing and one for I/O. It also had two internal DC100 digital minicartridge tape drives, a 24-linex80-character CRT display, a page-width thermal printer, and four I/O slots. The machine was a big, expensive gamble, and the Desktop Computer Division needed to get it out into the market ASAP. The only problem was that the HP 9845A's high-profile, high-speed I/O mode had a glitch, and the machine could not reliably "talk" to its optional external 8-in. floppy drive. The 9845 team needed a fix-fast-before releasing it to production.
