The Wallstreet is easily identified by the large white Apple® logo on the back of the screen, black keyboard, and the small multicolored Apple® logo centered at the bottom of the screen. The family number for the Wallstreet is M4753, and serial numbers (if still legible) will start with CK or QT, and the next two digits will be in the range 80 through 91. For example, QT9282H2EXW is not a Wallstreet serial number, while QT911053E6D is.
Early models, sometimes referred to as the "Wallstreet I" (250/292 MHz), or "Mainstreet" (233 MHz, cacheless), came with 12.1-inch passive matrix or 13.3/14.1-inch active matrix (TFT) screen. Ports included two PCMCIA slots, VGA, SCSI, Ethernet, Serial, ADB, headphone, microphone, 56k modem (optional), and an S-Video (except the 12.1-inch model).
Later models ("Wallstreet II" or "PDQ") were outwardly identical to the Wallstreet I, except they were only available with a 14.1-inch LCD. This model offered processor speeds of 233, 266 or 300 MHz. These models had the capability of driving the built-in display at multiple resolutions of 1024 X 768, 800 X 600, or 640 X 480. An easy test to distinguish a Wallstreet I from a Wallstreet II is to check the Monitors control panel to see if there is more than one resolution setting available. Checking the processor with the System Profiler is another simple test.
For a short time after the PDQ was released, a version dubbed the Wallstreet LE was available which had a 12.1-inch TFT LCD, 2MB video RAM, and a 233MHz Processor -- otherwise this model was identical to the PDQ.
Most parts are interchangeable on the various Wallstreet models. Exceptions are the screen hardware and plastics (to accommodate different size screens), logic boards (4 different versions), and 6 different processors (233/0k, 233/512k, or 250,266,292,300/1M cache). Worth noting is that the lack of cache in the 233MHz Mainstreet processor made it much slower than other Wallstreets. This is easily remedied by replacing the processor card with any of the other versions.
