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.

Replaced components:

• 2 x Diode IN4001
• 1 x Diode Zener 5v1

I have repaired last year these computers for a dear friend.

Commodore 128 #1

Defect:

• Black Screen.
• Missing CAS on PIN 1-4 of the 74LS32 (U9)
• Missing CHROMA video.

Fix:

• To fix the problem of lack CAS on 74LS32 i had to make a bridge from the PIN 41 of the PLA 8721 because a pcb track under the socket was interrupted.
• Broken solder joints on the RF Modulator.

Commodore 128 #2

Defect:

• Black Screen but sometimes it works.

Replaced parts:

• Replaced the socket of the 8721 PLA.
• Replaced 8721 PLA (U11).

Note:

The main problem was the PLA. In the C128 mode sometimes works and sometimes not. Works always C64 mode.

I have repaired a Commodore Amiga 2500 (A2000 Motherboard) with Black Screen for a dear friend.

Click to view original size

Defect:

• Black Screen.

Diagnosis:

• The Battery Acid has corroded a track (not visible to the naked eye) connected to the PIN 10 of the resistor packs RP900 and then the same track is connected to the CPU.

Repair:

• I have made a small bridge between the two points on the solder side of the pcb  and the problem was fixed in 5 minutes.

I have fixed 3 x Commodore Amiga 4000 Motherboards and 2 x Commodore Amiga CPU Cards for a dear friend. Below the description and photo of each repair.

Commodore Amiga 4000 Motherboard #1:

• I have done an accurate cleaning of the leaked battery acid even in the holes between pcb layers.
• Replaced some SMD electrolytic capacitors with a high ESR value.

Commodore Amiga 4000 Motherboard #2:

• I have done an accurate cleaning of the leaked battery acid even in the holes between pcb layers.
• Replaced all SMD electrolytic capacitors with a high ESR value.

Commodore Amiga 4000 Motherboard #3:

• I have done an accurate cleaning of the leaked battery acid even in the holes between pcb layers. I have also made a “bridge” because a track of the pcb was completely corroded.
• Replaced all SMD electrolytic capacitors with a high ESR value.

Still a couple of months with the battery acid and this Amiga was to throw in the trash.

Commodore A3640:

• Replaced all SMD electrolytic capacitors with a high ESR value and a first acid leak.

Fixed the problem of the 3 capacitors installed with the wrong polarity. The silkscreen on the pcb are wrong. Thanks Commodore.

CBM prg Studio Version 3.2.1 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:

• Screen designer speed up.
• Speed up of switching/adding/opening files and projects.

Bug Fixed:

• Assembler:
  • Duplicate labels not detected in projects.
  • SYS call always created at start of file.
  • Build order not correct.
  • Assembly dump showing both parts of the code within conditional assembly statements.
  • Code reformatting issues.
  • Negative numbers in BYTE and WORD sequences not assembled properly.
  • Numbers in strings in BYTE sequences not assembled properly.
  • Numbers in TEXT sequences not assembled properly.
  • Arithmetic in WORD sequences not assembled properly.

• General:
  • Sprite Designer grid glitches.
  • Exception thrown when generating .prg with the output window closed.
  • Code indent/outdent/comment/uncomment would add extra carriage return.
  • Code comment/uncomment would add extra REM statements.
  • Problem adding existing files to a project.
