All the ROM programs were written by Microsoft, and even a few of them were written by Bill Gates (!) himself ! These programs include a text editor, a telecommunication program, which uses the built-in modem (300 baud), and a rather good version of BASIC (no big surprise there). Kyocera made this computer for three main companies: Tandy, Olivetti (Olivetti M10) and NEC (PC 8201), these computers are the same except the case and some little differences in the programs and a few physical differences. The operating system uses 3130 bytes of the 8 KB RAM. So the 8 KB models (Catalog # 26-3801) didn’t sell very well. But there was also a 24 kb model (Catalog # 26-3802), and one year later, Tandy replaced the Tandy 100 with the Tandy 102 (which has 24 kb RAM too), and later with the Tandy 200 (1985). The Tandy 102 is 1/2 inch thinner and one pound weight different. The "Date-Bug" (random changing of the calendar) is also repaired from the Model 100. But many people still prefer the feel of the Model 100 as there are also more 100-only accessories on the used market than compatible accessories... The CMOS CPU (80c85) allows to use the Tandy 100 for 20 hours with only 4 AA batteries (5 days at 4 hours/day or 20 days at 1 hour/day)!! The model 100/102 is still considered and used as an excellent machine, mainly to type texts when you're on the move (you can transfer them to modern computers) and even to send and receive emails ! Fun fact : its CPU was also used on the Mars Pathfinder probe's Sojourner rover !

The Tandy TRS-80 model 100 "Micro Executive Workstation" was by far the most popular though, due to the Radio Shack chain of electronics stores throughout America. These are considered the world's first laptop computers, sporting a full-size keyboard, and enough ports to satisfy everyones needs. They all come with built-in software - the model 100 has: Microsoft BASIC programming language word processing software telecommunications software built-in 300 baud modem Small size, a good keyboard and display made the model 100 very popular, especially with people on-the-go. There is no internal storage capability other than the battery-backed RAM, and a cassette recorder or external 5 1/4-inch floppy drive must be used for permanent data storage. The optional Disk/Video Interface has both video connections for a TV or composite monitor, and one or two built-in SS-DD 184K 5 1/4-inch floppy drives. The model 100 was the last computer system of which Microsoft's Bill Gates wrote a significant amount of the code. Read more about it in the Bill Gates Interview from the Smithsonian Institute. The model 102 was released in 1986 for $499. It is similar to the 100, but is slightly smaller, lighter, and has a few of the bugs from the model 100 fixed. A year later in 1984, the TRS-80 model 200 was released - it is similar but with a larger screen..." =================================================Check the status of your shipment.  (Enter any usps tracking number)Combined shipping: Add $1.50 for each additional item.Shipped via USPS (United States Postal Service) thru Paypal shipping, endicia ( code 666827 )or Stamps.com  (Code  C- 5F5Y-7FK )Delivery confirmation number sent to winnerU.S. addresses verified by USPSNO "lost" shipmentsOptional Insurance (Amount for Merchandise Insurance Coverage Desired) Fee . . . . . . . . . .
