The Avatar was a Zorro III only graphics card, however it was never released to the public. It supports 24bit, and resolutions up to 1600x1200. It contained Composite (PAL, NTSC, Y/C, YUV) connectors with support for MPEG compression to hard disk with image capture. The card also supports EGS as well as Opalvision and Harlequin emulation. It also contained a built in genlock.
DJW microsystems
David John Westwood was the founder of DJW microsystems (DJW are the founders initials) and the designer of all DJW products.
A little history - Dave used to work at Amiga Centre Scotland many years ago and was involved in the development of the Harlequin board, but left and founded DJW Microsystems.
DJW microsystems used to assemble PCs and sell them but also did some custom hardware development.
The first major product they developed was the Black Box which only really got as far as the prototype stage, it was really designed to operate in the Amiga 2000 and occupied 3 slots in the case - the processor slot, a zorro slot and a PC slot (for power only). We got it operational but very buggy when we were approached by Tritec to act as distributors for us. They were interested in the Black Box, but really wanted a lower cost system and persuaded us to develop the Horizon card.
We got the Horizon working quite well (in terms of hardware), and operating as an Amiga graphics board, but in order to realise the full potential, we needed native software as the controller chip on the board is a full graphics processor (http://www.ti.com/product/tms34020a)
This is the time that we contacted a few programmers from Kefrens in Denmaark, initially to develop a 34020 assembler, but with a view to doing more work as well. I can't remember why this didn't work out, but the guys were really keen and great to work with.
Around this time, the bottom fell out of the PC market and DJW microsystems was in real financial trouble, so we reached a deal with Tritiec where Dave and one other guy became employees of Tritec and transferred the design to them.
