IBM ThinkPad 365 was a notebook computer sub-series introduced in 1995 by the IBM corporation into the market as part of their ThinkPad laptop series. It was succeeded in 1997 by the ThinkPad 760 series. The series had 8 models that were released.
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 — Being one of 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 — Being 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 100MHz, 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 and 1.35. 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 sub-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]
