The card was designed by Frank Fugledal and manufactured by Kjell Sundby in 2017. This card uses an SD memory card for emulating two 8 MB hard disks. I’ve arranged it so floppy and power cables are sticking out in the rear, so the Gotek can be easily attached if I need it.Ģ017 – hard disk : Installed an hard disk controller “emulator”. Later I decided to remove the Gotek, because I think it ruined the original look and beauty of the machine.

Very convenient for moving software from a PC. TIKI-100 in my collection My upgradesĢ016 – Gotek floppy emulator: Fitted a modern “Gotek” floppy emulator as a second floppy drive, it’s using disk image files from an FAT32 formatted USB memory stick. Finally, the computer worked just perfectly. I soldered in a wrapping wire to fix the broken trace. It actually was a broken trace surrounding the RAM chip after all (exactly what I looked for in the first place, but totally missed out on it). Soon he found out it was failing to copy a specific byte to the RAM after initializing the ROM at power on.

Then he checked the ROM assembler source code instruction for instruction upon the signal recordings. He had the assembler source code to the system ROM (TIKI-Monitor) and he connected his “test-lab-laptop” to the pins on the Z80 CPU and “recorded” the signals when turning on the computer. Later, after a replacing a lot of chips and testing with no luck, I got help from a friend, Frode van der Meeren, even at his young age his such an expert. TIKI 100 – replacing the capacitors and RAM chips. I measured to check if it was break in any traces surrounding the RAM chips then, couldn’t not find any broken traces. I then replaced all the old RAM chips and inserted sockets for the new ones. I replaced all the capacitors on the main-board to prevent this for happening again. When I powered it on the second time, It smelled burned, smoke was coming out and shortcut noises. An early original box from my collection, KONTIKI-100 is relabeled into TIKI-100. I suspected a failure in one of the RAM chips making up the 64 KB system RAM. The flashing was a good sign, means most of the computer was probably working as there is some “testing” in the ROM’s software, making the LED flash. When I got it, the screen was black with no picture at all, but the mainboard got powered on and a keyboard LED was flashing. I bought the computer from someone that had found it at an disposable & recycling center. On the cardboard box itself, the KONTIKI name has been scrambled with a black marker pen. On my own TIKI-100 unit, the KONTIKI labels on the rear has been masked, and also the labels on the mainboard print circuit. Thor Heyerdahl opened a legal case on the use of the Kontiki name, with reference to the name of his famous raft, and after loosing a short battle in the city court, the name was changed to reads simply TIKI-100. Tiki-100 was released under the original name ‘Kontiki-100’ in early 1984 (some “pre-run” units has started shipping from August 1983 I think). This put forth the need and memory requirements to run more complex applications. While other educational computers at the time had a main focus on BASIC and simple computer-science, the Tiki-100 had more focus on being a tool to aid in education and everyday-life situations. The machine was given good sound and graphic capabilities for its time. I’ve read that one other requirement was at least 32 KB RAM. One of the most influential of these specifications was compatibility with CP/M and the Z80 CPU. The Tiki-100 was was partly influenced by the specifications laid out by the government. It was decided by the government that Norwegian schools should use a “standard” computer. Discontinued: 1989 (continued into the early 90’s in some extend).Backward compatibility: CP/M-80 2.2, +with Intel 8088 CPU card (or rev.D): CP/M-86.

Memory: 64 KB RAM, + with Intel 8088 CPU card (or rev.D): 256-736 KB RAM.CPU: 4 MHz Zilog Z80, optional 4 MHz Intel 8088 CPU card.
