Victor 19-1421 1973 Logic Technology: LSI-2 Memory Technology: LSI Display: PPX Victor is the Victor Comptometer Corporation, a company with a long standing producing mechanical calculators for the business/accounting market. This is one of their electronic models produced as the bottom dropped out of the mechanical market. The Victor 1900 series followed shortly after the 1800 series. The keyboard - a design shared with the 1800 series - is of high quality, built to withstand the heavy daily use of accounting departments, with a low-wear contact arrangement and a double-action mechanical mechanism that controls and limits the forces seen at the contacts. With that said, these keyboards do have a failure mode, see the associated note.

Hewlett-Packard 9815A 1976 Logic Technology: LSI,MSI,SSI Memory Technology: LSI Display: PPX2 Based around a Motorola 6800 microprocessor, with 14 KBytes of firmware in ROM. A lot of functionality packed into a small desktop form factor, including the ability to interface to external I/O devices. Servicing these units is awkward as the main boards are folded tightly over each other. Extension connectors can be constructed to permit operation and access with the boards unfolded.
