IBM ThinkPad 300

The IBM ThinkPad 300 was one of the first ThinkPad notebook computer's that was released by IBM in 1992. The IBM ThinkPad 300 was released alongside the ThinkPad 700 series, and was meant to be a low-end, cheaper version of the 700 series.
History.
The ThinkPad 300 was made by Zenith Data Systems, instead of IBM. It was launched on October 5, 1992 alongside the ThinkPad 700 series. 
Contrary to earlier IBM computers, IBM sought for an OEM to develop the 300. Eventually, executive authorization was granted. Because of a pre-existing agreement with Zenith/BULL, IBM negotiated with them about the notebook that would become the 300.
Although introduced at a price of $2,375, by February of 1993 the price dropped to $1,999 then even lower to $1,699 by May of 1993. This was due to poor sales of the ThinkPad 300.
Features.
The 300 was based on the 25 MHz Intel 386SLC with 4 MB of memory, and had a nickel metal hydride battery that was claimed by IBM to up to 10 hours. It also had the option of an 80 or 120 MB hard disk drive and it had a 9.5in 640x480 monochrome screen with 64 scales of grey. Other features it had was DOS 5.0 preinstalled, and for ports was a modem, serial, VGA, parallel, ethernet, and port replicator. Alongside the hard drive, it had a built in 3 1/2 1.44 MB floppy disk drive.
As the 300 was meant to be low-end and cheaper, it was missing some features the 700 series had suck as the TrackPoint device. 
Although the thinkpad came with monochrome screens, they could later be upgraded to a active color TFT screen.
Reception.
"PC Mag" regarded the ThinkPad 300 as a decent choice, thanks to the good screen and above average battery life backed by flexible power management.
