The Dragon 32 was built in South Wales, first in Swansea and then in Port Talbot, and sold well in Britain for a short while in 1982 and 1983. It was close to the Tandy TRS-80 Color Computer inside, and came with Microsoft's Extended Color BASIC.
Its 6809 processor was one of the most advanced 8-bit chips of the day, and its keyboard was a proper full-travel one. Dragon Data closed in 1984.
Its text screen was 32x16 characters, dark green on light green. The graphics modes showed a fixed set of colours each: 128x192 in four (green, yellow, blue and red, or buff, cyan, magenta and orange), or 256x192 in two. There was no black in the four-colour sets and no lower-case text.
No sound chip. The processor pushed values to a 6-bit converter, giving one voice that could play any wave the programmer could calculate fast enough, at the cost of everything else stopping.
