    At the end of the TI/4A is the number one home computer in America, with approximately 35% of the market share, and producing , consoles a month. In February , in order to remain competative, TI again cut the price to dealers, and the cost of a TI/4A dropped to about $ My first home computer was the TI/4A from Texas Instruments. I wanted to get a “real computer” (I had an Atari at the time), I bugged my parents, and I got to choose from what was on the () Continue reading →.

    Each 'switch' is described as a BIT. In order to pass information more quickly, the computer looks at more than one BIT at a time. The TI99/4A uses a 16 bit processor: it is able to look at 16 bits at a time. For most purposes however, the computer looks at 'words' composed of 8 bits. These words are called BYTES. I hope you enjoy your visit to my site. I have used a TI/4A since , and it is really a great computer. It still has a substantial following, and I still use mine to this day. I hope you find something useful and interesting on these pages. Feel free to sign or just visit the guest book. You may just recognize some names from the past!

The main purpose of this message is to delay VDM99 until the hook routine on the TI/4A is ready to accept command. Answer [Yes] to scan for drives and populate the TI/4A sub-tree. Describes the software modules produced by Texas Instruments for use with the TI/4A home computer. Among the modules described are: Personal Real Estate, Programing Aids, Home Financial Decisions, Music Maker, Weight Control and Nutrition, Early .
