The First Computer Of The National Association Of Investigative Specialists, 1970's

The Kaypro Computer above had no hard drive but had two flopper disk drives. You would put the program you wanted to use in one drive and then use the other drive to save data to. It ran a word processing program called Word Star and had a little database program to do mailing labels. This was the first computer used by NAIS with a eight inch black and white screen.The specs where: Z80 processor, 2.5 MHz, 64Kb RAM memory, integrated keyboard, integrated 24-row, 80-column monitor, 2 SSDD 5-1/4" floppy drives. On the back are a reset button, telephone modem port, serial data i/o, serial printer port, keyboard port, brightness control, power on/off switch, power cable port, and a fuse plug. Below is a photo of the Acoustically Compelled Computer Modem. With an Acoustically Coupled Computer Modem, you would place the phone handset on top of it. The baud rate was maybe 50. Enough speed to send maybe a one page document of text (there was no graphics) at about the blazing fast speed of three or four minutes. State-of-the-art for it's time as not many people even knew what a modem was. With printer and all the goodies it ran about $6,995.00. That would be well over $10,000 by today's standards!
