A 6502 Personal System Design: Kompuutar | 94 |
The design information included with this article, together with the excellent documentation provided by MOS Technology on the 6502 design, should be complete enough to enable the advanced experimenter to build a similar Kompuutar. The detail provided here cover a basic processor, but do not include a detail design of a programmable memory board which is a necessary part of a usable system. David Brader is currently working on an 8 K dynamic memory board, with invisible refresh, to be used in Kompuutar. The details of the wiring and construction of Kompuutar are shown in the several figures, tables and photographs, as well as listing 1. |
