Vector Graphic Flashwriter II
The Flashwriter II was for years Vector's
workhorse video display board.
There was not an earlier Flashwriter I.
The two refers to the 2K of RAM the board used. The Flashwriter II delivered the
critical 80 characters/line with 24 lines per screen required for practical
office text processing with each character in a high resolution 8X10 dot matrix.
The Flashwriter II had good circuitry for flicker-free screen updates and had
separate sync (inverted & non-inverted) outputs as well as composite video
CRT's. There was also a parallel keyboard input port. Unusually the board had a
socket for your own system monitor in ROM as well as the ability to jump to that
location on Reset or POC. It did however utilize system memory making VDB
boards with their own onboard memory a better choice, for example the
Later a Flashwriter IV was produced. It
had 4K of RAM and a serial keyboard input port.
