Features

All models shipped with Windows 95 but were capable of running up to Windows XP, if they have a sufficient RAM upgrade, as well as several Linux variations.

With only 8 MB of included ram, these ThinkPads were better suited for older operating systems such as Windows 3.1. If the ram was however upgraded using the slot on the motherboard, Windows 95/98 could run more properly. The maximum size the ram could be upgraded to was 40 MB, later being increased to 72 MB.

The series used Socket 3 IBM/Cyrix processors up until the E and ED, where they began switching to Intel Pentium I processors running from 100 to 133 MHz.

The standard hard drive size in the series was 540 MB, with optional sizes of 340 and 810 MB up until the X and XD, where the hard drive sizes was changed to 1.08 GB and 1.35 GB with an additional 2.1 GB option in 1997.[1] If the user wanted to upgrade their hard drive capacity past this, the BIOS had a hard drive capacity limitation of 8.9 GB because of BIOS INT 13H.

The ThinkPad models ending with a D included a CD-ROM drive, the rest included a 1.44 MB floppy disk drive. Ones that had a CD-ROM drive had a proprietary external floppy disk drive port on the back.

Models and specifications

IBM ThinkPad 365C – The first models in the series, it featured a Cyrix Cx486DX4 running at 75 MHz, 8 MB of soldered EDO RAM, which could be maxed out to 24 MB using the onboard 144-pin RAM slot, and hard drive sizes of 340 or 540 MB. It came with a 10.4" TFT display in 640x480 resolution, and weighed 6.2lb. The price of the 365C was $2,200.

Other features included: Non-removable 1.44 MB floppy drive, Infrared transceiver, TrackPoint III pointing device, and 1 Type III or 2 Type II or 2 Type I PCMIA slots.[2]

IBM ThinkPad 365CS – The second model in the series, the 365CS was identical to the 365C, with the only difference having a 10.4" DSTN display with 640x480 resolution over the TFT display of the 365C.[2]

IBM ThinkPad 365CD – The third model, the 365CD, introduced a few new features, such as a non-removable double-speed CD-ROM drive and having sound, with a built-in speaker and ES1688 audio controller. It came with a standard 540 MB hard drive and a 10.4" TFT 640x480 display.

Other features included: Infrared transceiver, TrackPoint III pointing device, and 1 Type III or 2 Type II or 2 Type I PCMIA slots.[2]

IBM ThinkPad 365CSD – Having the same basic setup as the 365CD, the CSD's only change was the 10.4" DSTN display. The 365CSD cost $2,499.[2]

IBM ThinkPad 365E – The 365E model came with a new IBM/Cyrix 5x86 running at 100 MHz, a 15 MHz speed increase from the previous models. It came with the standard 8 MB of soldered EDO RAM which could be maxed to 24 MB if upgraded. It came with 2 display options, a 10.4" DSTN or TFT at 640x480 resolution, and a standard 540 MB hard drive with an additional option of 810 MB. Later versions of the 365E and ED had a Pentium 1 running at 100 MHz instead of the IBM/Cyrix 5x86.[3]

IBM ThinkPad 365ED – The 365ED having the same setup as the 365E, had a CD-ROM drive, ES1688 audio controller with built-in speaker, and a 10.4" DSTN display with 640x480 resolution over the 365E.[3]

IBM ThinkPad 365X – Being one of the last models of the series, the 365X introduced a few new specs and features. It came with a Pentium possessor running at 100–120 MHz, 8MB of soldered EDO RAM which was upgrade-able to 40 MB (72 MB later on), and larger hard drive size options of 1.08 GB and 1.35 GB. The 365X had screen options of a 10.4" DSTN or TFT display at 800x600 resolution. Later on it had the option of a 11.3" DSTN display at 800x600 resolution. It started at $2,099 for a Pentium 120 version and later dropped to $1,399 in early 1997 when IBM began cutting prices on older ThinkPad models.[4]

Other features included: Non-removable 1.44 MB floppy drive, Trident Cyber9320 video controller with 1 MB video ram, ES1688 audio controller with built-in speaker, Infrared transceiver, TrackPoint III pointing device, and 1 Type III or 2 Type II or 2 Type I PCMIA slots.

IBM ThinkPad 365XD – The last model of the 365 series, had the same basic setup of 365X with only one minor difference of a 6X CD-ROM drive. IBM later introduced other versions of the 365XD, one a "new model" and the other an "upgraded model".[1] The new model consisted of a Pentium I running at 133 MHz, 1.35 GB hard drive, 6x or 8x CD-ROM, IR transeiver, 8 MB of soldered EDO RAM which was upgradable to 40 MB (72 MB later on), and an 11.3" SVGA DSTN display.[5] The "upgraded model" consisted of a Pentium I running at 120 MHz, 1.08 GB hard drive, 6X CD ROM drive, and a 10.4" SVGA TFT display which had 64K color support.[1]

Note – the "D" in the model number signifies the machine had the updated chassis with provision for fitment of a CD-ROM drive, or when using an adapter plate, an internal floppy disk drive. The models without the "D" didn't officially come with the updated chassis.
