D > DICK SMITH > VZ300   

Dick Smith

Dick Smith released the VZ-300 (same model as the VTech Laser 310) in 1985. It was basically a VZ-200 with 16K RAM (the VZ-200 had 8K RAM), a slightly updated BASIC ROM and a better standard keyboard.

The 16K cartridge could be plugged into the VZ300, as well as a new 64K version, but it only gave a total of 34 KB. Only language machine programs could take advantage of the extra 32 KB thanks to the Z80 bank switching facility.
