Pertec Computer Corporation (PCC), formerly Peripheral Equipment Corporation (PEC), was a computer company based in Chatsworth, California which originally designed and manufactured peripherals such as floppy drives, tape drives, instrumentation control and other hardware for computers. Pertec's most successful products were hard disk drives and tape drives, which were sold as OEM to the top computer manufacturers, including IBM, Siemens and DEC. Pertec manufactured multiple models of seven and nine track half-inch tape drives with densities 800CPI (NRZI) and 1600CPI (PE) and phase-encoding formatters, which were used by a myriad of original equipment manufacturers as I/O devices for their product lines. In the 1970s, Pertec entered the computer industry through several acquisitions of computer producers and started manufacturing and marketing mostly minicomputers for data processing and pre-processing. This split up Pertec into two companies. Pertec Peripherals Corporation (PPC), which remained based in Chatsworth, California, and Pertec Computer Corporation (PCC), which was located at 17112 Armstrong Avenue, in Irvine, California. ==Pertec and MITS== Pertec bought MITS, the manufacturers of the MITS Altair computer, for US$6.5 million in 1976. This purchase was motivated mainly by the ownership of the Microsoft BASIC sources and general license that Pertec erroneously assumed to be included in the deal. As a result of the acquisition, Pertec became involved in the manufacturing of microprocessor-based computers. Their first models were expanded versions of the Altair models, typically coupled to the existing disk-drive range. These sold reasonably well, but as the decade closed, it became apparent to the company that the Altair's day had passed, due to new competition from other small computer makers like Apple, Commodore and Radio Shack. In 1978, the company launched the first of its own designs, the PCC-2000.〔 〕 This was based on two Intel 8085 series microprocessors: one of which was given over to I/O control. Being a high end machine, it was intended to be the core of what would now be described as a workgroup. The machine was intended to support four "dumb" terminals connected via RS-232 serial lines, in addition to its internal console. The basic machine had twin 8-inch floppy drives, each capable of storing 1.2 megabytes and could link to two Pertec twin 14-inch disk drives, giving a total of 22.4 megabytes of storage, which was a very large amount for the time. The system was generally supplied with a multi-user operating system called MTX, which included a BASIC interpreter that was similar to Business Basic. The PCC-2000 was also available with MITS DOS or CP/M. In the UK, several systems were run under BOS. Unfortunately, the PCC-2000 was too expensive for the market and was never a great success. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pertec Computer」の詳細全文を読む スポンサード リンク
