The IBM 5216 Wheelprinter, released in the early 1980s, was designed to be attached to a PC.
The machine uses daisy-wheel printing technology, where raised characters are set on spokes radiating out from a central hub. The machine's print mechanism is a simplified version of that of the IBM 5218 Displaywriter printer.
The IBM Proprinter II was one of IBM's second generation printers for personal computers.
The machine is a 9-wire dot-matrix printer that can produce 40 characters per second at high quality settings and 200 characters per second at lower quality.
It connects to a PC via Centronics parallel interface.
The IBM PC AT was the company's second-generation personal computer and was announced in 1984.
The machine was initially powered by an Intel 286 processor running at 6MHz, while later models ran at 8MHz.
The PC AT could support up to 16MB of RAM and initially had one 20MB hard drive. Expansion was via six 16-bit expansion slots and two 8-bit slots.
The display was usually driven by an IBM monochrome Display/Printer adapter or an IBM Colour/Graphics Adapter. Machines released later used the IBM Enhanced Graphics Adapter and, sometimes, Professional Graphics Adapters.
