The Keyboard Component was a peripheral that combined with the Master Component to create a fairly capable computer. Mattel Electronics made a limited release of the Keyboard Component and subsequently offered to repurchase them when it decided not to release them to the wider market. As a result, there are very few Keyboards in the wild.
The Keyboard provided the following major components:
| 6502 | The Central Processing Unit (CPU) contained in the Keyboard |
| TMS9927 CRT Controller | A text-only 40x24 display controller that gen-locks to the Master Component's STIC |
| CRT RAM | A text frame buffer for the CRT Controller |
| Shared RAM | 16K x 10-bit wide RAM, visible both to the Keyboard's CPU and the Master Component's CP1610. |
| Tape Drive | A block addressable, fully-CPU controlled tape drive, offering 2 digital and 2 analog tracks |
| 6502 Cartridge Port | A second cartridge port for 6502-specific software, such as Keyboard BASIC |
This page is a stub, but I wanted to get at least something here. I will upload Keyboard Component related photos and docs later. --Mr Z 18:45, 29 June 2006 (EDT)
