Man is still the most extraordinary computer of all.
(John F. Kennedy)
Kiwi - a 68k Homebrew Computer
For the future, my plans are to program some simple games.
|CPU||MC68008, clocked at 10MHz|
|RAM||4MB DRAM, 512kB dedicated VRAM|
|Video||Yamaha V9990 Video Display Processor|
|Audio||dual SID stereo (MOS6581 or MOS8580)|
|Mass storage||IDE/ATA and floppy disk interface (WD177x)|
|Time/Date||Realtime clock Epson RTC72421|
|Network||10base-T Ethernet (CS8900a)|
|Interfaces||PS/2 compatible Keyboard and Mouse ports|
Two Atari style Joystick ports
RS232 and parallel ports
|ROM||32KB EPROM with IDE/ATA Boot Code|
|Operating system||Enhanced Basic 68k or EmuTOS|
The operating system is a modified version of Enhanced Basic 68k. When the system is switched on, the look and feel is as old school as it was intended to be. One can just start typing
RUNlike used to do two decades ago.
As for development, only free tools and free software have been used. This includes the gEDA suite to create schematics and the printed circuit board layout. Critical lines have been routed by hand, while a major routing work has been done with the autorouter of freerouting.net. The development operating system is linux. The board has been manufactured by PCB-Pool. Everything is hand soldered.
