CBM prg Studio Version 3.3.0 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.

Improvements:

• Sprite Editor:
  • Add background picture to sprite editor.
  • Sprite reorder tool.

• Character Editor:
  • Character tools work on a range of characters.

• Assembler:
  • Import binary as decimal data
  • Improved value pop-up formatting
  • Removed the restriction where files included in a build must have a name when building the project as a batch.

• BASIC:
  • Code reformatting remove zeros from DATA statements.
  • Option to ignore invalid GOTO destinations.

Bug Fixed:

• Assembler:
  • Reformatting code with TEXT directive.
  • Using * with labels.
  • Wrong rules for ifdef when variable is zero.
  • Debugger problems with X and Y indexing, stack under/overflow, SBC, RTI, BRK.
  • Incbin problems with large files.

• BASIC:
  • Output to disk image generating basic programs.
  • ‘Save File As’ only saving BASIC files.
  • Commenting blank lines.

• Character Editor:
  • Wrong colours changed on the character editor for VIC20 projects.
  • Undoing character editor changes when the character index > 127.

• Sprite Editor:
  • Scratchpad exception when using deleted sprites.

• General:
  • Syntax colouring changes not applied properly until restart.
  • Some BASIC only tools were available to the assembler.

Relaunch64 is an IDE (text-editor) for C64 assembler-coding on Windows, Linux and Mac OS X. Relaunch64 has a clean and intuitive user interface, yet it offers many features that make coding faster and easier.

Java 7 or higher is required to run Relaunch64. The program is licensed under the GNU GPL 3 (or higher) and free for private and professional use.

This editor works together with common cross assemblers like Kick Assembler, ACME, or 64tass. Other assemblers might work as well, but syntax highlighting may not be 100% correct.

I have repaired the Commodore Amiga 2000 with a Black Screen for a dear friend.

Defect:

• Black Screen.

Diagnosis:

• The Battery Acid has corroded some pcb tracks (not visible to the naked eye) connected to the pin of the resistor packs RP900.

Repair:

• I have made three small bridges between the points on the solder side of the pcb and the problem was fixed in a short time.

The Commodore 3040 it’s a dual drive 5¼” floppy disk subsystem for Commodore International computers. It uses a wide case form, and uses the IEEE-488 interface common to Commodore PET/CBM computers.

These drive models use a similar single density, single side floppy data storage format to that used by the Commodore 1541 drive, but with a slightly different data marker indicating which model originally formatted the disk. The low-level disk format was similar enough to allow reading between models, but different enough that one series of drive models could not reliably write to disks formatted with one of the other model series.

The Atari 8-bit family is a series of 8-bit home computers introduced by Atari, Inc. in 1979 and manufactured until 1992. All are based on the MOS Technology 6502 CPU running at 1.79 MHz, roughly twice that of similar designs, and were the first home computers designed with custom co-processor chips. This architecture allowed the Atari designs to offer graphics and sound capabilities that were more advanced than contemporary machines like the Apple II or Commodore PET, and gaming on the platform was a major draw – Star Raiders is widely considered the platform’s killer app. Machines with similar performance would not appear until the BBC Micro in late 1981 and the Commodore 64 in 1982.

The original Atari 400 and 800 models were released with a series of plug-n-play peripherals that used Atari’s unique “SIO” serial bus system. Over the following decade several versions of the same basic design were released, including the XL and XE series of computers and matching peripherals. All of these used the same basic logical design, with various changes to the physical layout to lower production costs as chipmaking and manufacturing processes improved over time. The early machines were expensive to build, but dependable. Later models like the XEs were greatly cost-reduced and generally not as robust. Sub-models of these later designs were sold into the eastern European market after sales of the main lineup had ended.

Overall, the Atari 8-bit computer line was a commercial success, selling two million units during its major production run between late 1979 and mid-1985, putting its sales on par with machines like the Sinclair ZX Spectrum and TI-99/4A. Its primary competition in the worldwide market was the Commodore 64, by far the best selling computer of the 8-bit era. Atari also found a strong market in Eastern Europe and had something of a renaissance in the early 1990s as these countries joined a uniting Europe. Some estimates place sales during this period at another two million units.

Atari 825 – 80 Column printer:

Atari introduced with its Atari 400 and 800 series computers its first 80 Column printer.   The Atari 825 which actually a repackaged Centronics 737 printer.   Earlier models had limited capabilities, the later 825 models with the extended basic character set had the capability of producing the Atari ATASCII graphics character set.  The Atari 825 required the use of the Atari 850 interface module to allow it to communicate with the Atari 400 and 800 computer because it had a Centronic parallel interface on it instead of the Atari SIO interface which the Atari 820 and Atari 822 printers had built in.

I finally found a time to do the replacement of all the electrolytic capacitors of my Amiga 1200 that was beginning to have serious problems of stability.

Since I had disassembled the amiga i took the opportunity to do the E127R fix that solves some problems of graphics glitches with the interface Indivision AGA 1200.

The fix is very simple to do, you need to short the E127R resistor with a jumper.

I have also replaced the original power supply of the Amiga with a ATX power supply can supply more ampere and is a little stable than the original.
