    Dr. Steve Vickers writer of the ZX Spectrum ROM firmware

    How did you come to work for Sinclair Computers?
    I wrote to all the computer companies I could find out about in the Cambridge area, and asked if they had any jobs. I ended up at Nine Tiles Information Handling, who were doing contract work for Sinclair. The owner John Grant had already written the firmware for the ZX80, and my first task was to adapt it for the ZX81 by writing a floating point maths pack and some other new features. I also wrote the user manual. After that I did the same...

    Amstrad





    Amstrad released the CPC (Colour Personal Computer) 464, it's first home computer, in 1984. With sales in excess of 2 million throughout Europe

    As with many other 8 bit machines of the day, the Amstrad CPC 464 was powered by a Z80 processor. After failed attempts to use a 6502 as used by the likes of Commodore 64, the CPC 464 ran at 4MHz and had 64K of memory available with AmsDOS (Amstrad's built-in Operating System). The CPC 464 offered three display modes;...

    started a blog post Sinclair SE Chloe

    Sinclair SE Chloe

    The SE, codenamed Chloe, is a modified Timex TC2048. The modifications were specified by Andrew Owen and designed and implemented by Jarek Adamski. Within each section, you may find links to additional information elsewhere in this FAQ, or to other reference documents.

    Technical Specifications:
    The technical specifications for the ZX Spectrum SE are;
    • Codename: Chloe.
    • I/N: TC2280.
    • CPU: Z80A @ 3.528Mhz.
    • Total RAM: 280K.
    • Video RAM: 27K.
    • ROM: 64K (32K active, 32K passive)
    • Sound: AY-3-8912.
    • Keyboard: Cherry PS/2 Notebook.
    • Mouse: Amiga 2-Button.
    • Joystick: Kempston.

    Hardware: For most people, the final specification of the ZX Spectrum SE is probably not a concern, since it is just one potential system to run Sinclair Extended Basic on - although I would love to see it supported by emulators. If you were holding out for all those new graphics modes I dreamed up, or if you just want a modern Z80 based machine right now, then I would recommend the Sprinter from Peters Plus Ltd. I am working with Peters to ensure that Sinclair Extended Basic will run on the Sprinter. If you want to build your own Spectrum from off-the-shelf components then you should look at Mike Wynne's SpeccyBOB. In theory it should be possible to build a ZX Spectrum SE based on the SpeccyBOB schematics, and it will support Sinclair Extended Basic via a drop-in EPROM. If you got very excited when Zilo...

    SEGA Mega Drive (Genesis) Mini

    Sega is the latest 90's console to try and cash in on people's yearning for their lost retro years. Following in the footsteps of Nintendo, Sega is releasing a 'mini' form of it's amazing Mega Drive console that adorned many a teens' bedroom some 25 years back.

    And who wouldn't want this? OK, we completely understand that neither Nintendo's nor Sega's offerings are going to compete with more modern concepts of a console such as an Xbox one x. But there are those who love to hop on...

Filmation, an isometric view, was used in many of their games but their best selling games had to be JetPac & Sabre Wulf, each selling a staggering 300,000 in '83 and '84.
