Tiki Data Kontiki-100 (later renamed Tiki-100 to avoid a legal dispute over the "Kon-Tiki" name).
A 1984 computer with Z80 CPU that could run C/PM. The "100" refers to the 100K of memory the prototype system had (the final product had 104K, having the ROM increased from 4K to 8K). It used TTL based graphics hardware, had 3 graphics modes, and hardware vertical scrolling. Text modes ("terminal emulators") were simulated in graphics modes. The built-in keyboard was an N-key rollover. That means the system is instantly aware of all key changes no mater how many are used simultaneously, no buffering, and pressing multiple keys at once does not create phantom keystrokes. Much like game controllers of the era (if they had 92 buttons). It came with a C/PM lookalike OS called K/PM (kinda like Atari's TOS looked like MacOS). However, C/PM software could actually run on K/PM (or K/PM could seamlessly launch a C/PM instance?). K/PM was perceived to be copy of C/PM so the company renamed the OS to Tiko. It also came with BBC BASIC and COMAL.

The released version of the Kontiki-100 was actually the cost-reduced Kontiki-100 Rev. C. Some Rev. A and Rev. B machines may have made it into the wild through legitimate channels.

The 8/16 upgrade added an 8088 CPU capable of running CP/M-86 and a version of MS-DOS but it was not IBM-PC compatible. It used Tiki Data's TIKOS operating system that could also run CP/M-86 software.

A hard drive was available and could be swapped with one of the 5.25" floppy drives.

A serer version of the Tiki-100 running MP/M could be used with a network hub to connect up to 16 Tikis and 3 printers. It came with a hard drive installed.

The Tiki-100 Rev. D was an IBM PC compatible that also had a Z80 CPU. It was seamlessly backward compatible with the Tiki-100. Although, 16 color graphics with a 256 color were reduced to CGA standards. The Z80 was in charge of the system bus that was shared with an 8088. The Rev. D was a commercial failure.

The Tiki 200 is a IBM-PC compatible and not backwards compatible. It should not be part of a Tiki 100 platform.

My take:
Tiki 100 platform with warnings to editors not to include Tiki-200 and that x86 games for "Tiki 100" may not actually be Tiki 100 specific. And, note to editors the usual C/PM issues in the way there are usually noted~.
