The quick way to tell whether you have an '83 or on '84 is to look at the back of the computer. '83's have one serial port, '84's have two (DB-25's, of course). '84's also have video attributes -- inverse, dim, underline, and blinking. They also can display block graphics, and have a fine line drawing character set available. The '83's can only do blinking video, and they have a Greek alternate character set. Of course, all of the Kaypro 10's had two serial ports and graphics. To tell them apart, you will need to open up the case to look at the motherboard. If the cable that goes the hard disk controller host adapter board attaches to the middle of the motherboard, its an '83. If it attaches at the edge by the disk drives, its an '84. They were several different machines that Kaypro called a 2 (or II): Early Kaypro II '83 - 2 SSDD drives, 2.5 MGHZ, no graphics Late Kaypro II '83 - 2 SSDD drives, 2.5 MGHZ, no graphics - Has Kaypro IV motherboard, so you can just plug DSDD drive to upgrade. Kaypro 2'84 - 2 SSDD drives, 4.0 MGHZ, graphics New 2 - 1 DSDD drive, 4.0 MGHZ, graphics Kaypro 2X - 2 DSDD drives, 4.0 MGHZ, graphics - Some of these have builtin real-time clock and 300 bps modem, like the 10 '84's When I bought mu Kaypro, I ordered a New 2, but it turned out that Kaypro wasn't making them anymore, so I would up buying a 2X instead. Mine came without the clock or modem. -- Jeff Wieland wieland@acn.purdue.edu
