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:

• Programs are project based, meaning all related source files, sprite files etc. are kept in one place and multiple source files can be linked more easily.
• Tabbed MDI.
• Syntax highlighting.

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:

• Assembler:
  • Logical operators.
  • Code relocation.
  • Watch labels/addresses.
  • Local character mapping.

• Screen Editor:
  • More export options.
  • Change border colour.

• Sprite Editor:
  • Multiple layers for preview.
  • Invert sprite.

• General:
  • Load VICE palettes.
  • Open a command line.

Bugs Fixed:

• General:
  • Remember ‘close start page’ state.

• Sprite editor:
  • Imported sprites had the same data.
  • Select mode on scratch pad didn’t work.

• Screen code builder:
  • Left arrow generated wrong code.

• Character editor:
  • Export characters as hexadecimal.
  • Multicolour chars flip left/right not working.

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.

• 1 x MOS 6526 (U1)

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:

• Solder resistance from E232R that is disconnected because the acid of the capacitors has leaked and corroded..
• Solder the transistor Q233 that is disconnected because the acid of the capacitors has leaked and corroded.
• Rebuilding a dozen pf pcb track between the IC U12 and the rest of the PCB and rebuilding also the through holes of the PCB.
• Replacing electrolytic capacitors, probably due to the state of the pitches i don’t use SMD capacitors.
• Replacing the male Harddisk connector some legs are broken at the base because the acid of the capacitors has leaked and corroded.

Gallery of the repair & cleaning:

1234►

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.

• Soldered the E232R resistor, it’s no a good soldering because the pad are in a badly state but working.
• Soldered a transistors Q233 (2N3904) not SMD, the pitches are gone when i have tried to solder the SMD version.
• Rebuilt 10 x connections doing a horrible jumpers in bizarre places.
• Replaced the electrolytic capacitors.
• Replaced the male connector for the Harddisk.

It’s a shit … but it works!

Commodore Amiga 600 Gallery (Before & After):

Yet another Commodore 64 (USA-NTSC) repaired.

Defect:

• Garbage screen / Black screen.

Repair:

• Replaced 1 x PLA 906114
• Replaced 1 x MOS 7708 (74LS257)

Note:

• The first time the Garbage Screen was in Black & White and then after replacing the PLA 906114 a new Garbage Screen is back with some colors :-D (see photo)

Commodore PET 2001 Chiclet (1978) Fixed.

Defect:

• Garbage screen.

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.

DirMaster is a Windows-based GUI application designed to help Commodore enthusiasts explore and manage their disk image collections.

DirMaster supports common (and uncommon) emulator disk image formats (such as .d64, .d81, .d2m, etc), almost every native Commodore archival format (such as .arc, .sda, .lnx, etc), and many native graphic formats (such as koala, doodle, amica, etc).

DirMaster was designed to give users a perfect blend of familiar appearance (e.g. natural looking disk image contents using the PETSCII character set) and modern GUI functionality (e.g. drag and drop, opening multiple disk images at once). The first version of DirMaster was released in 2006.

v3.1.1 addresses a few bugs reported by users:

• Issue opening NAT partitions (.dhd)
• .dhd performance (no md5, .dhd BAM)
• Horizontal BAM display (.d71)
• Disk initialization when unzipping a 1-4! zipcode set when dragged from Explorer.

• Add %H parameter to run in, to convert filename to $ hex characters.
• File properties adds file size in bytes and md5 hash.
• Ctrl x/c/v in a directory window will cut, copy, and paste files to and from the clipboard (mimics Windows Explorer behavior)
• Mouse over a sector in the BAM shows the file name and sector.
• Selecting a file will number the linked sectors in the BAM.
• Tweaks to batch output (html, seq, txt, csv), GEOS file handling, disk error handling (23/24/27/29), sfx/sda title handling, PETSCII tool.
• Bug fixes addressing d2m, d4m, d81, t64, g64, nib and other general functions.
