The Pachislo (パチスロ) slotmachine project

  PACHISLO  パチスロ In de week voor zaterdag 4 oktober zag ik op marktplaats voor 45 euro een fantastisch leuke Japanse gokkast te koop staan. Ik als elektronica freak die Japanse elektronica te gek vind, kon ik het niet laten de vraagprijs te bieden voor de kast. De verkoper verkocht de kast zijnde defect. Zelf had hij geen tijd om de kast te repareren. Dit was voor mij geen probleem. Het is of repareren en als dat niet lukt de kast als donor gebruiken voor mijn zelfbouw slotmachine project. Op 4 oktober ben ik met de auto vertrokken om 7:30 uur in de ochtend naar Lichtenvoorde. Dit plaatsje ligt in de achterhoek. En is het is 2.5 uur rijden om daar te komen vanaf Groningen. In de schuur van de man stond op een werkbank de gokkast. Zonder te testen heb ik de kast gekocht en in de auto gedaan. Het viel me mee hoe groot de kast is. Namelijk maar  ongeveer 70 x 40 x 45 cm. Thuis aangekomen ben ik meteen aan de slag gegaan. Allereerst is de gokkast gemaakt voor 110V n...

The finishing touch

Afbeelding
It is finished !!!!! Me playing Nemesis 1 by Konami. It looks like a new computer again. Since the Sony MSX has a second FDD connector on the backside I could not resist making an external drive. This makes copying disk more easy and faster. After some cad work and 3D printing a new external drive was born. For the power supply I bought an old printer powersupply of 5V and 12V output at a secondhand store. The second Sony drive needs a small modification to make it work as B: drive. A jumper setting needs to be made to set the drive in secondairy mode.

  Almost done!!! It looks like I am almost finished with this project. The computer housing is finished including 3D printed FDD holder. I had to design this holder because the drive I use is a Sony PC FDD 1.44Mb version. The height of this drive is only 25mm. And an orginal drive is 30mm. After some minor modifications, I managed to mount the FDD in the housing. Please take a look at the difference between the computer housing before and after cleaning. Next step is to finalize the keyboard. I am waiting for the backside of the keyboard housing to be white after UV treatment. Next time you will see the result.  Check the bonus picture at the end of this post. Also the inside is clean! Goodnight, Lifeline 2020

MSX 2 Sony HB-f700-E refurbishment The mouse is the first part which will be cleaned. First the mouse needs to be disassembled. The plastic part will be whitened and the mechanical parts will be lost from dust, hairs and other smuts. Next pictures shows the bag with H2O2 cream and the plastic parts to be treated with UV light. UV treatment. The aluminium foil is to protect the environment but also to reflect UV on the top side of the parts. The cable has sticky nicotine on it. This is probably the most disgusting computer cable I have ever seen. But the result of cleaning in soap and bleach is impressive. I did not use UV to make the cable look white again. maybe I will do it in the future. I am afraid that the contacts gets wet.   After all parts are cleaned this is the result. Looks like new again.

 Welcome to my new blog about vintage electronics  In my leisure time I like to repair, refurbish or design electronic devices. My first project to show you all is about repair and refurbish of a Sony MSX-2 HB-F700 from the eighties. I bought this computer the day before yesterday for only 75 euro. The state in which the computer is is quick poor. The smell of nicotine, the discoloration due to smoking and UV light over the years.  I close this article for now. I will continue updating in new articles. I hope you will enjoy my future blogs. Lifeline
