What do Timex Sinclair 2048 and IBM PCjr have in common?
Timex Sinclair 2048 The Timex Sinclair 2048 although never produced, was to be an improved version of the Sinclair ZX Spectrum computer. It was not released by Timex Corporation because of TS1500 failure. According to an early Timex Sinclair 2000 computer flyer, it would be a cut-down TS2068 with 48 KB of RAM and advertised as a 48 KB memory machine (The TS2068 might have been called the 2072 because of the add of 24 KB ROM + 48 KB RAM = 72KB).
IBM 5110 The IBM 5110 Computing System was the successor of the IBM 5100 Portable Computer.
