my HOBBy pages

I have recently rediscovered retrocomputers from the 80's and 90's, and since been working on retroprojects related to repairing these computers, playing retrogames and developing novel solutions for these computers, such as wireless joysticks and keyboards and audio-video modifications. I am always looking for new (pun intended) retro 8-bit computers from 80's.

See my retroproject and other pages from the links at the top of this page or at GitHub, my Youtube channel for some project and retro gaming videos (I have made some discoveries and exploitable bugs in somewhat old computer games), Thingiverse for retroprojects and my Internet Archive page, to where I have scanned and uploaded some retro computing and electronics documentation that I found missing on the Internet.

My collection of retro hardware (pics to appear..)

Currently I have a set of Commodore 8-bit computers (VIC-20, C16, C64, C64C, Plus/4, 128 and 128D) and 16-bit (Amiga 500 and Amiga 2000). I also have several Sinclair computer models (ZX81, Spectrum 48k and ZX Spectrum +2A), Amstrad CPC 464, Spectravideo SVI-728 and 16-bit Atari ST 520. Somewhat rare in Finland, I have also collected Acorn Electron, Tandy TRS-80, Dragon 64 and Sega SC-3000 home computers. An extraordinary item in my collection is the Finnish made Salora Manager. At the high end, I own an original IBM PC and old Macintosh models Classic and SE.

I am a nostalgic retro gamer, thus playing once again the childhood games with retro game consoles, such as Philips Videopac, several version of Atari 2600, Atari 7800, Mattel Intellivision, Colecovision, Nintendo Entertainment System, Sega Master System II, Sega Mega Drive, Nintendo Game Boy and GameCube, Playstation PS One and several versions of Pong.
