| | The SWTPC. SOUTH WEST TECHNICAL PRODUCTS M6800 |
 | | SWTPC used these chips to design a computer that was simpler to build and program than the Altair design, and cost much less to manufacture. | | | SWTPC eventually withdrew completely from the "hobbyist" market, and only built business machines and special purpose computers that were used in point-of-sale systems and other commercial applications. | | | When you first looked at the SWTPC 6800 Computer System, you noticed it was completely unlike the Altair or IMSAI computers. |

| | The SWTPC 6800 was the first computer system made by The SouthWest Technical Products Corporation and the first based on the Motorola 6800 microprocessor. | | | Before manufacturing computers, SWTPC sold home audio kits and a kind of computer terminal called "Television Typewriter". | | | User had to buy an additional terminal to enter information, and thus a ROM monitor allowed him to examine and modify memory, load/save programs on tape or boot from a floppy disc unit. |
