History of 20 years MSX Info Pages
In 1998 I started to experiment with publishing websites, mainly to show the results of my research in the MSX Video computer hardware and software. At that time the only source of information were the hard to get Service Manuals, MSX Technical documents and books like the Red Book.
In the years that followed I acquired many documents and spent thousands of hours scanning and publishing, also with great help from many fine contributors, the result of that work is shown on this website: a free and maintained information source on the technical part of MSX.
The website has undergone many changes, and had many url’s as you can read below.
It is now stable for many years at msx.hansotten.com, on a solid CMS: WordPress.
The site is here to stay, no plans to retire, I keep on administrating and continue paying for the hosting, even if I do not have any physical MSX hardware, software or document!
A small request (which is largely ignored and abused by the wiki authors of msx.org!): link to pages and not to files! I guarantee pages to keep the same url, files will move around my hosting sites and links to files and images will go dead.
With the aid of MSXHOLDER aka ABUUR I have added some missing pages to the NMS8245 service manual.
When I made the scan of the Philips VG-8230 and VG-8235 service manuals, I only had a photocopied low quality version of the manual.
The quality of PCB and circuit diagrams were not optimal.
Thanks to Jipe (Jean-Pierre Dubois) I now have improved circuit diagrams(VG-8230 and VG8235) and PCB (VG-8230).
