Two systems which play a major role in the Computing & Gaming Life of Urs König

It's not really a "versus" thing, more a kind of family get together of the two cousins!

Codename: ZX-83 Jaguar °c.n.
Developer: Sinclair Research Ltd, Cambridge, UK FLARE II Ltd, Cambridge, UK for Atari Corporation, Sunnyvale, CA, USA
Key people: David Karlin (HW), Tony Tebby (OS), Jan Jones (BASIC), Rick Dickinson (Industrial Design) John Mathieson and Martin Brennan (HW, FLARE II), Jeff Minter (SW), Ira Velinsky (Industrial Design), Richard Miller (Vice President Technology)
Link: In 1983 John Mathieson did a hard disk interface for the QL which was demoed at the launch but never went any further. In 1985 at Micro Peripherals Ltd Richard Miller developed a floppy disk interface for the QL which was later sold under the Sinclair brand name. Richard Miller joined Sinclair Research in 1985 and developed the ASIC of Sinclair's Z88 portable. The two processors, code named Tom and Jerry, were designed by Martin Brennan and John Mathieson while at Flare II. Nick Terry wrote the cross assembler for the two custom processors and Tim Dunn did additional work on the chip set and project managed the CD drive accessory after moving to Atari. All ex Sinclair Research. So was Richard Miller, VP at ATARI.
Intended market introduction: Autumn 1983, to generate sales for Christmas 1983. Target was missed. Fall 1993 °c.n., to generate sales for Thanksgiving and Christmas 1993. Target was missed.

Key colours in CI/CD: Black, Silver, White Black, Red, Yellow
Marketing slogan: Sheer professional power in the special Sinclair style DO+THE MATH
Community slogan: QL forever! Jag rules!
What blow me away: BASIC language, 32-bit multitasking OS, visual appearance (black) Alien versus Predator (AvP), Tempest 2000 (T2K), visual appearance (but should have been in dark black like the prototypes and early cartridges)
Got my 1st personal unit: On January 20th 1986, bought in the post Christmas 1985 sales at a consumer electronics retailer in Berne In spring 1995, bought from Jochen Merz Software, a German trader with whom I was doing business for almost a decade

as appearing in the movie "Jag is 20" - 20th anniversary 2013

°1 - Expansion cards with MC68000/12, MC68000/16 or MC68020/24 CPU were available in the early 1990s.
°2 - Expansion cards with 768KB, 2MB (with MC68000/16 CPU) and 4MB RAM (with MC68020/24 CPU) were available in the late 1980s and early 1990s.
°3 - The original specification was 32KB ROM for the OS and BASIC. During development OS and BASIC became bigger as planned. Production machines had 48KB ROM which resulted in the expansion ROM limited to 16KB.
