The Sharp PC-1500 was the first ultra-mobile computer I saw and owned. It was released 30 years ago in 1982 and was also available from Radio Shack as the TRS-80 PC2. It had an 8-bit processor and, if I recall correctly, 2KB of memory. It even had a BASIC interpreter built-in to let you write your own software. The photo above shows the PC-1500 plugged into its optional expansion port which provided a cassette tape interface (for data) and a four-color pen plotter! A tube containing a spare set of pens is seen at the bottom of the photo.
Ultra-mobile computers usually came with some kind of carrying included. I do not know if this case is real leather. But, you can see that it has stood the test of time very well at age 30. An iPhone 4 is seen below the PC-1500 to provide an idea of its size.
Its “chiclet” keyboard had a QWERTY layout and was reasonably easy to use. BASIC keywords could be entered with a single keypress. The clear plastic keyword tempate in this photo is laid over the PC-1500 in this photo. The LCD display had a 156×7 resolution. There is no typo in the previous sentence. The display had a 7 pixel vertical resolution. You could, however, address each pixel individually to produce monochrome graphics. Even primitive animation was possible on the display.
The port on the left side of the PC-1500 plugged into the optional expansion dock.
Sharp made sure you had key accessories for the PC-1500. You can see the PC-1500 and its expansion dock sitting in a custom case with pouches for the power adapter and supplies. Again, I do not know if the case is made of real leather. However, as you can see in the photo above, it is in great shape after 30 years.
I got good use out of the Sharp PC-1500. It was my main “super-calculator” for many years.
There an excellent fan page for the device where you can find more information: http://www.pc1500.com/
