The print of the case for the Commodore Floppy Drive 1541-II Harlequin version has been finished with a total print time of 23 hours (slow print mode), including filament drying.
These are the changes made to the original designs:
- The feet on the bottom of the case have been removed to avoid the need supports; non-slip feet can now be applied without any problems.
- The depth of the square hole on the front panel for the Commodore logo has been reduced.
- Removed the POWER and DRIVE text on the faceplate embossed and not printing correctly with a new carved text.
- The hole on the front panel for the MeGALoDOS OLED has been closed.
- Commodore label for the front panel.

Yet another Chinese product, but for €13 it was worth trying this crazy piece of crap. It works well for the price, but the problem, as I suspected, is the focal length, which is practically zero.
The protective ring MUST be placed on the object, so if we need to identify SMD components, such as 201 or 402 format, it “COULD” be fine, or if we want to see moles on the skin, leaves, hair, tiny insects, a cat’s butthole might even be fine, but if we want to use this lens to analyze broken tracks or micro short circuits with a PCB that uses THT components, it’s no good, absolutely useless because hits the components/pins/soldering points, the viewing range is limited, i should be much further away, but the lens doesn’t allow it and consequently it doesn’t focus.
Perfect gift for my daughter :-D

A kernal ROM adapter and switcher for C64/C64C/1541/1541C/1541-II
The Switchless Kernal Switcher (SKS64) switch kernals with the RESTORE key on the C64. Automatically switch the kernal in the disk drive using the reset signal. The color of the RGB power LED indicates the current kernal.
The project recommends using the W27C512 EEPROMs but in the lab i have only the SST27SF512 available which are compatible pinouts.

The High Voltage SID Collection (HVSC) is a freeware hobby project which organises Commodore 64 music (also known as SID music) into an archive for both musicians and fans alike.
The work on the collection is done completely in the Team and contributors’ spare time and is proudly one of the largest and most accurate computer music collections known.
This update features (all approximates):
- 623 new SIDs
- 72 fixed/better rips
- 8 repeats/bad rips eliminated
- 280 SID credit fixes
- 10 SID model/clock infos
- 11 tunes from /DEMOS/UNKNOWN/ identified
- 1 tunes from /GAMES/ identified
- 25 tunes moved out of /DEMOS/ to their composers’ directories
- 4 tunes moved out of /GAMES/ to their composers’ directories
After this update, the collection should contain 59,886 SID files!

The return of the Hybrid Sid Player by xAD/Nightfall
Based on the Project and Hardware Schematic by Markus Gritsch released in the years 2011-2015 on the forum dangerousprototypes. Thanks Markus.
Changelog:
v2.10 – 16/6/2025
Added:
- Added the info of the video mode on the OLED (PAL – NTSC – Both – Unk), the info is alternated with the VB: CIA or VBI.
Updated:
- Improved the verification of the Socket number for the FPGASid in the configuration file and error reporting on the display if it is incorrect.
- FPGASid Socket Error
- Check the config.in
- FPGASid Disabled
- The default SID Socket (DEFAULT_SID_SOCKET) in case the Auto Switching mode is used will always be the Socket where the FPGASid has been installed.
Fixed:
- Playing the song “Acrouzet_-_Your_Indecision.sid” i found a bug, the Player did not choose the right Timing for NTSC and consequently the playback of the song was too slow. The problem was that this song uses VBI with NTSC timing, usually you can find CIA songs with NTSC timing. It was a bug in the player that it couldn’t get the correct information from the SID header.

CBM prg Studio Version 4.6.0 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.
System Requirements:
- CBM prg Studio will run on any recent PC hardware, The only requirement is .NET 4.6 (minimum) must be installed.
New features in v4.6.0:
- Option to check for new version on startup.
- Option to treat “PI” as a keyword or not.
- In the debugger, moving the mouse over the screen RAM window will show character and address info.
- In the debugger, there is an option to skip Kernal calls.
- In the screen designer, there is a layout selector for the ‘map’ tab.
- {insert} can be used for screen code 148.
- In the character editor, values can be pasted into the raw data text box.
Bugs Fixed:
- After creating a Kick assembler project, ‘Generate and launch’ would fail if the project properties had not been shown first.
- In the screen designer, selecting the reverse of character set 2 would throw an exception.
- In the screen designer, importing screen data into a multi-colour screen would render it in single colour.
- Adding a new item from the menu bar would throw an exception.
- ‘Generate and Launch’ for a project did not use the most recent source files.
- Reformatting assembly code would not work if a line started with a ‘@’ (with a lable).
- Reformatting BASIC code (removing zeros) not working with DATA statements.
- Reformatting BASIC code (removing spaces) not working with DATA statements.
- MOUNT keyword missing from mega65 projects.
- Open Output Folder for a kick assembler project would fail if no output folder was defined.
- Some UI tweaks (buttons not visible etc.)

This RGB mod by Yannick Erb was made to work with three different consoles:
- VideoPac including BG Color Fix
- Intellivision only model with LM1886N
- Atari 2600
I wanted to try this RGB mod even though i am the man who created the ZOE RGB way back in 2013 for Intellivision but on my Intellivision i still had the rough prototype of the mod installed and since i no longer time to assemble a new ZOE RGB interface for Intellivision i have decided to try this one by Yannick which is basically identical to my interface.
I configured the RGB mod to work with Intellivision, there are some jumpers to configure, everything worked at first try the image is clear and stable thanks also to a small trick that this mod includes, a capacitor on the SYNC line that makes the image more stable in some situations.
I also took advantage of completely removing the RF modulator (absolutely useless) and in the hole of the antenna plug i fixed a DIN connector for the RGB / Audio output and SCART Switching, i also replaced the flat of the power cable of the intellivision motherboard because it had completely disintegrated.
Below you will find the usual photo gallery and the download of the GERBER + the files needed to assemble the PCB by JLCPCB.

This is the right way for the Scart Switching with source of 12v.
