[2] 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 myriad original equipment manufacturers as I/O devices for their product lines.

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.

The machine was intended to support four "dumb" terminals connected via RS-232 serial lines, in addition to its internal console.

The complete 300/55 business system sold for $15,950 and included the Altair 8800b with 64k of dynamic RAM, a CRT terminal and a desk.

[10] The system was designed to handle a variety of business applications including word processing, inventory control and accounting.

This line was opened in the first half of the 1970s by the Pertec PCC-2100 data entry system, which was essentially different from the PCC-2000 mentioned above.

The other one featured two large capacity disk units (up to 70 MB formatted capacity, manufactured by Kennedy or NEC), one line printer connected through long-line interface (DataProducts LP600, LP1200, B300, Printronix P300, P600), four station printers connected through coaxial cable (Centronics), one card reader (Pertec), four SDLC communication channels and 30 proprietary coax terminals (Model 4141 with 40x12 characters or Model 4143 with 80x25 characters).

The data entry was either described in several tables that specified the format of the input record with optional automatic data validation procedures or the indexed file operations were programmed in a special COBOL dialect with IDX and SEQ file support.

These BASIC database business systems would be purchased by outside companies that bundled the PCC 3200 with their software to provide a complete small business package (accounts payable, accounts receivable, payroll, inventory, sales tracking, taxes, etc.)

The 3200 was extremely advanced for the time, being intended to support up to 32 users, all using intelligent Z80-based terminals, each of which could optionally run CP/M attached to the 3200's high speed coax cable.

It was the first Pertec product to support the emerging "Winchester" standard for miniature hard disks.

[16] During the transition from systems based on custom-made CPUs to CPUs made by Intel and Motorola, prices for these systems dropped dramatically, but without an offsetting increase in demand, and eventually companies such as PCC slowly dwindled away to small remnants of their peak days in the mid-1980s, or were bought out by larger companies.
