The IBM 5120 Computing System (sometimes referred to as the IBM 5110 Model 3) was announced in February 1980 as the desktop follow-on to the IBM 5110 Computing System. It featured two built-in 8-inch 1.2 MB floppy disk drives, 9-inch monochrome monitor, 32K RAM and optional IBM 5114 stand-alone diskette unit with two additional 8-inch 1.2 MB floppy disk drives.[1] The system was sold with both APL and BASIC languages in ROM and provided a toggle switch on the front panel to select the language. APL allowed numerous business software written on IBM minicomputers to run on the 5120.[2] Other computer data storage products were available from Core International, Inc for these machines.[3]

Aside from larger screen size and performance benefits over its predecessor, the IBM 5120 design incorporated several usability advantages:

  • Reduced 'footprint' requiring less desktop space
  • Reduced glare on monitor, keytop and product surfaces
  • Ease of handling/lifting based on bottom form treatment
  • Reduced static loading in arms and shoulders due to keyboard palm rest

For its usability features and appearance, the IBM 5120 was recognized with two major industrial design awards and described with terms such as ″clean, well thought out″; ″subtle detailing shows great care in execution″; and ″looks like quality″.[4][5]

It was launched in 1980 as the lowest-priced IBM business computer to date. Depending on the options the overall system prices ranged from $9,340 to $23,990. To emphasize its office image IBM released in that same year 6 new programs: task inventory, billing, payroll, accounts payable, accounts receivable and general ledger accounting.[1]

In 1983, Core International introduced PC51, software that allowed 5100 Series computer programs written in BASIC to run unmodified on the IBM PC and compatibles under PC DOS.
