The IBM Thinkpad 350 series was a notebook computer series introduced in 1993 by IBM as part of their Thinkpad laptop series. It was the successor to the IBM ThinkPad 300.[1] With only 2 models ever made in the series, it was succeeded in 1994 by the IBM Thinkpad 360 series.
History
The 350 was announced in June 1993.[2] The 125MB disk version started shipping in June 1993, the 250MB version started shipping in July.[3]
The New York Times noted that IBM challenged Compaq with the development of the 350, who was the market leader in the lower priced notebook market.[4]
Both models in the series came with an Intel 486SL running at 25 MHz, and a CT-65530 video controller with 1 MB of video memory. Both models also had a standard 4 MB of RAM that was on a proprietary IC DRAM Card. If a user wanted to upgrade the ram, the 350 ThinkPads supported an IC DRAM Card size up to 20 MB.
Both in the series came with a 125 or 250 MB standard hard drive, and a non-removable 1.44 MB floppy drive. Both models also had a battery life up to 9 hours.[5]
In March 1994, IBM cut the prices by 12%.
The 350 is identical to the PS/Note 425 and the 350C is identical to the PS/Note 400SL/25.
Models
IBM ThinkPad 350 — The first model in the series, it introduced a Intel 486SL running at 25 MHz, a monochrome 9.5" STN display with 640x480 resolution, 4 MB of ram on an IC DRAM Card, a non-removable 3.5" 1.44 MB floppy drive and a 250 MB hard disk drive. The 350 weighed 5.2lb in total, and started at $2,099. Other features included: Trackpoint II, Type II PCMIA slot.[5]
IBM ThinkPad 350C — Basically the same as the first, and also the second and last in the series, it only had 1 notable change to a 9.2" STL LCD 640x480 256 color display. It also added the additional option of a 125 MB hard drive alongside the 250 MB option. It weighed 5.7lbs, a .5lb gain from the base 350 model. The 350C started at a price of $1,999 with the highest being $2,399.[5]
A review by the Los Angeles Times considered the ThinkPad 350 not an impressive machine due the fact it was bundling IBM DOS instead of MS-DOS or Microsoft Windows.[6] A review of the 350C by InfoWorld noted the good screen and the relatively short battery life.[7]
