The Japanese Commodore 64 was introduced in the 1983.
The Hardware somewhat different (and incompatible) Kernal and BASIC to accomodate Japanese katakana characters, 46 total (plus punctuation, diacritics, etc.); many graphic characters replaced in the Char ROM with the new Japanese characters.
Breadbox case and original brown keycaps; SHIFT-LOCK replaced with C= LOCK for the purpose of getting at the katakana; modified keycaps to show the new characters with the colour keys no longer present and the remaining graphic characters significantly rearranged.
Machine started up in English but different colour scheme and only 36863 bytes free; see screenshot. Both Markus and On the Edge remember the original screen as black on pink, but the screenshot and corresponding ROM definitely aren’t.
Graphics and Sound Identical to the breadbox 64.

Directly from the collection of a dear friend “Andrea Pierdomenico” the Commodore 64 with the wrong key.
The factory was wrong to print the “8″ key but only the upper label and not the front label. I did not find any articles on the net that talks about this keyboard, the only one in the world?

CBM prg Studio Version 3.5.0 is released. There are a lot of new features in this version. I’d really appreciate it if you report any bugs you find or have any suggestions/comments.
CBM prg Studio allows you to type a BASIC or Machine Code program in using a nice Windows environment and convert it to a ‘.prg’ file which you can run on an emulator, or even a real C64 / VIC20 or PET if you’re feeling brave and have the right kit.
CBM prg Studio is the result of merging C64PrgGen and VIC20PrgGen. Adding new features and fixing bugs in two apps which were 95% similar was a bit of a nightmare so merging them made sense.
It was also a good opportunity for a face lift and to add some new features, such as:
What CBM prg Studio isn’t is a front-end for tok64, cbmcnvrt, bastext or any other tokeniser / detokeniser / assembler. It’s all been written completely from scratch.
New features in v3.8.0:
Bugs Fixed:
See the help for a complete list of new features and fixed bugs.
Note In this version, each target machine can have its own default project directory. If you are upgrading from a previous version (before version 2.5.1) of CBM prg Studio you may be asked to set up your project directories again. Your current projects will not be affected.

The motherboard conditions are not good, very badly. All capacitors have released acid, some are gone and the same for other components like the transistor Q233 2N3904 SMD amplifying for the video signal BLUE RGB. The Decoder U12 CXA1145 Sony has the pins eaten by the acid of the capacitors.
Poor Amiga …
Work to do:
Gallery of the repair & cleaning:
I start to saying that this type of repair should NOT be made, are not good although the repair can succeed, these damaged motherboards are good for spare parts.
It took me 10 hours to repair and if i ask 15,00 euro per hour like a housekeeper, would be 150,00 euro excluding components and cleaning case … but who pays 150,00+ euro ? no one in the world. :-D
This is one of the reasons because do not exist anymore electronic repairs or there are very few people can do it, nobody is willing to pay.
Works that have been made:
Foreword almost all pcb pads are leaked of the acid, although i have cleaned more times so as not to heat the electrolyte liquid that is worsening the situation, unfortunately the pcb pad could not resist to a new solder and they are broken.
It’s a shit … but it works!

Commodore PET 2001 Chiclet (1978) Fixed.
Defect:
Repair:
The problem of this computer was caused by the oxide on all pins of the RAM and inside of the sockets as you can see from the photos.
To clean the pins of the IC i always use the same way, gently with a rasp nail on the ic pins and then spray a bit of air, see photo.
For cleaning the socket i scraping with a fine tip gently the contact inside the socket.
I have tested all with the ROM/RAM board and simulating the various BASIC and configurations of RAM and loaded some software, including my demo with the PET MicroSD by Dave Curran (Tynemouth Software)
Everything worked perfectly.
As you can see from the photos i have now a complete workstation for repair PET 2001 out of the box, avoiding to have on the table the computer that takes a lot of space.
