The Tiki-100 is a quite regular mid-80's Z80-based (home-)computer. It was designed and sold in Norway, and was mostly used by schools.
It got 64KB RAM, 16KB ROM (8KB of them is for an optional ROM module which can be placed in a socket on the motherboard), 32KB video RAM, and a 4MHz Z80. The different parts of memory can be accessed through bank-switching.
It has 3 video modes, all of them are bitmapped. It's 256x256 @ 16 colour, 512x256 @ 4 colour and 1024x256 @ 2 colour. Each colour is in the format of RRRGGGBB, and vertical shifting/scrolling is possible using the I/O port in the sound chip. The sound chip is an AY-3-8912; one of the most used soundchips of that time (at least in Europe).
The floppy controller used is either a Western Digital FD1767PL or a FD1797PL. Known formats are:
- FM/40 cylinders/single sided/18 sectors @ 128 bytes (90KB)
- MFM/40 cylinders/single sided/10 sectors @ 512 bytes (200KB)
- MFM/40 cylinders/double sided/10 sectors @ 512 bytes (400KB)
- MFM/80 cylinders/double sided/10 sectors @ 512 bytes (800KB)
It got 2 RS-232 ports, a printer port, and various display interfces. One of those DIN connectors can easily be wiered to the SCART input of any PAL-based TV for a better quality picture (RGB vs. Composite/RF mod).
Sadly, the software market for this computer never took off. As a result, no programs are really taking full usage of what this computer is capable of doing. The OS (KP/M) is compatible with CP/M 2.2 software, but that's mostly text-only programs.
