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.

Texas Instruments TI-99/4A Repair (#1)

Defect:

• Blue Screen with tiny Vertical lines.

Replaced parts:

• 1 x MCM6810P (128 x 8-Bit Random-Access Memory TTL/DTL)

Texas Instruments TI-99/4A Repair (#2)

Defect:

• Blue Screen with tiny Vertical lines.
• Wave/Raster Lines.

Replaced parts:

• 2 x IC MCM6810P (128 x 8-Bit Random-Access Memory TTL/DTL)
• 1 x IC CD3236A-NL (ROM)
• 1 x Capacitor 12 pF.

Note:

In one photo you can see the curious change made in this TI-99/4A by inserting a resistor in the pitch where in other motherboards is soldered a leg of a electrolytic capacitor and then one leg of the capacitor is welded and the not the other leg.  Compliments.

Video of the defects:

A new version of the firmware for the interface C64SD Infinity + ITS Module by Manosoft is released.

Changelog:

• Implemented functionality that allows to save a placeholder (unique for each .TAP file) pressing the red button on the back of the card. User can set back the read pointer at which TAP data is played back by pressing “Next” button on the card. Useful for multi load .TAP or games asking to reset the counter of the tape and then to rewind the tape that specific point.

Repair Commodore Amiga 600 (White Screen)

Defect:

• White Screen.

Replaced parts:

• 1 x LM555 (SMD)
• 1 x Electrolytic Capacitor 10uf 25v

Note:

I have thought it was a problem of RAM (U17) since i have measured oddities but the problem instead is a capacitor of 10uF, dead LM555 (smd) and some pcb tracks corroded.

Repair Philips 8220 (MSX2) Black Screen with Sound.

Defect:

• Black Screen but with sound (keyboard works)

Replaced parts:

• 2 x Fuse 250v 315ma
• 4 x Tantalum Capacitor 22uf 6v
• 1 x Electrolytic Capacitor 100uf 25v

Note:

The main problem was caused by the lack of +12 volts that power the RGB Encoder module. The other voltage of -12 volts are used only for the cartridges port (but not all cartridges using this voltage)

I wanted to do a experiment to install a standard PC drive with a adapter (34 pins to 14 pins) on a Philips 8245. I would say that it work but i have tried about 20 Floppy Drives and only 1 it works ;-D

SNDH archive v4.4 released – 4261 SNDH files (total 8268 tunes)

Ever since the birth of the Atari ST, different chip music formats have had different ways to use them. If you are coding a chip music player for the Atari ST you would have to use dozens and dozens of special ways to replay music.

But in the mid 90′s, BDC of Aura crew became tired of this inelegant system and decided to fix the issue once and for all. He then created the ‘SNDH’ file format. SNDH is actually the original songfile and replaycode with a header bolted on top of the music and replayer. The header has a unified calling interface no matter what type of chip music is hidden beneath it, and it has extended datas about the music.
