IBM ThinkPad 360

Most models in the 360 series shipped with Windows 3.11 as the included operating system, while some such as the 360P and PE shipped with IBM DOS 6.3 and PenDOS 2.2.

All models in the series featured an Intel 486SX or DX2 possessor running at 33 to 50 MHz, and a WD90C24A2 or WD90C24 video controller with 1 MB of video memory. All models also had a standard of 4 MB RAM, which was on a proprietary IC DRAM card. The ram could only be upgraded to a 20 MB maximum, if the user has the required IC DRAM card.

The standard hard drive size was 170 or 340 MB, later adding the option to 540 MB. All models in the series had a 1.44 MB floppy disk drive in an ultrabay.

Two notable models in the series, the 360P & 360PE, featured a pen touch display, which could also fold back and down to close like a tablet.

IBM ThinkPad 360 — One of the first models in the series, it introduced a Intel 486SX processor running at 33 MHz. With the 4MB IC DRAM card, it could only be upgraded with a maximum 20 MB IC DRAM card. It featured a 9.5-inch monochrome screen, and could hold a battery charge up to 10 hours. Other features included: 170 or 340 MB hard drive options, a 3.5-inch 1.44 MB removable floppy drive, Trackpoint II pointing device, and 1 Type III or 2 Type II or 2 Type I PCMIA slots.[1]

IBM ThinkPad 360C — Released the same time as the 360, the 360C model was basically identical to the 360 but with a 8.4-inch TFT color screen, and a decrease to 7 hours of battery life. It had a .5lb increase in weight, and a price increase of over $1100 compared to the base 360 model.[1]

IBM ThinkPad 360CS — Also released the same time as the 360C and 360 base model, the 360CS model was also identical to the 360C and 360, with only a few differences. It had a 9.5-inch DSTN screen, a slight increase in battery life from 7 to 8 hours, and a slight weight increase of 0.1lb.[1]

IBM ThinkPad 360P — The 360P model introduced at $3,399 was a unique model, as it featured a pen touch display. The pen was a pressure-sensitive input device (Stylus). It had a DSTN 9.5-inch 640x480 display. The machine ran IBM DOS 6.3 and PenDOS 2.2. Other features included: Ultrabay with 1.44 MB floppy drive, Trackpoint II pointing device, and 1 Type III or 2 Type II or 2 Type I PCMIA slots.

IBM ThinkPad 360PE — The 360PE model was almost identical to the 360P, having a small upgrade to a Intel 486 DX2 running at 50 MHz, a 17 Mhz increase in speed. It also offered a slightly larger hard drive size option of 540 MB, and was the first and only model in the series to offer built-in audio with a CS4248 audio controller. The 360PE cost $300 more than the 360P at $3,699.

IBM ThinkPad 360CE — One of the final models, the 360CE was a slight upgrade from the earlier 360/C/CS models, offering a Intel 486 DX2 running at 50 MHz, a 8.4-inch 640x480 TFT display, and an additional 540 MB option for hard disk size. Other features included: Ultrabay with 1.44 MB floppy drive, Trackpoint II pointing device, and 1 Type III or 2 Type II or 2 Type I PCMIA slots.

IBM ThinkPad 360CSE — The last model of the series, the 360CSE was again another nearly identical model as the previous unit, only offering a 9.5-inch 640x480 DSTN display rather than the 360CE's TFT display.
