Hardware CPU The first two models, the 200M and 200C, used the
Cyrix Cx486SLC. This was Cyrix's first processor, which was a
386SX pin-compatible chip with on-board
L1 cache and
486 instructions, being known as a "hybrid chip". The processor was
clocked at 33 MHz and had 1 KB of L1 cache. It was a
16-bit processor and was pin compatible with the
Intel 80386SX. On the bottom of the unit, the motherboard had an empty socket for a
Cyrix FasMath co-processor, which could improve
floating-point math performance. The 200M and 200C plus models had a Cyrix
Cx486SLC2 clocked at 50 MHz, which was 50% faster than the original 486SLC. The SLC2 similarly had 1 KB of on-board cache and was pin compatible with the previous model.
Graphics & Display For video all models used three versions of the
Chips & Technologies 655xx, the CT65520, 65525, and 65530. The 65520 was first introduced in early 1992 as the first controller with
Super VGA resolution. It supported resolutions up to 1024x768 in 16 colors or shades of gray. If in 800x600 resolution, it can display up to 256 colors. All 3 chips were the same, with the CT65525 identifying as a CT65530. The CT65530 had an ability of 5V and 3.3V mixed operation and linear video memory addressing. All models used a 9.5in 800x600 resolution DSTN LCD. The 200M and 200M Plus had a monochrome display, while the 200C and 200C Plus had a color display.
Audio All models had only basic audio available, with just a
piezo speaker soldered onto the motherboard and no sound controller.
Memory Standard RAM included was 4-8 MB of
EDO RAM. The RAM was on a proprietary
SIPP package that could only be upgraded to 12 MB maximum if the user had compatible modules.
Storage For storage all models used a hard drive with a size of 100 or 200 MB, and all models had an internal 1.44 MB floppy disk drive located on the side of the unit. The maximum capacity hard drive compatible if the user wanted to upgrade was 500 MB.
Ports & Expansion For ports all models had 1x
serial, 1x
parallel, 1x
VGA output, and 1x
PS/2 keyboard/mouse input. For expansion all models only had one
PCMCIA type II slot.
Keyboard & Mouse All models used a small-scale keyboard with control keys. One interesting feature of the keyboard is that the J key also acted as a mouse, working similar to IBM's ThinkPad
TrackPoint. On some models additional keys such as S, D, F, G and space let you do other mouse actions such as right click, left click, double click, and middle mouse click.
Software The series shipped with MS-DOS and
Windows 3.1 as the included operating system. == Model Comparison ==
