Bondwell Model 14

The Model 14 was the first CP/M personal portable computer to be introduced by Bondwell in 1984. The display CRT is quite clear and comfortable to read from and if it’s considered small for your taste you can connect to a standard TV through the composite port at the back. The Dual drives are a bit noisy when accessing data but very reliable. As a portable machine is on the heavy side, but in the 80’s it was considered impossible to carry around a personal computer as a luggage. The only drawback is that no internal batteries were available so the only power source was the Mains Plug. The Main features where portability, build in speech synthesizer and compatible with Kaypro systems.
