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.
Some of the new stuff in v3.1.0:

TRS-80 Model 1 L2 – Video Snow Shovel Hardware Fix
Video snow, the black streaks against white characters, is most apparent with large, rapidly changing areas of white graphics. The root of the problem is that the TRS-80 display is memory mapped by the CPU.
The solution is to give the video circuitry higher priority than the cpu.
Note:
On my TRS-80 Model 1 where i use the Quinnterface & FreHD i had to use the version that also includes the 74LS125 which seemed optional but in this case it does not appear to be optional, we have to do it, otherwise doesn’t work.
Thanks to Ian Mavric for the support.

One of the most famous limitations of the TRS-80 Model I was its inability to display lower case characters.
Although the lower case characters were present in the character set, the Model I lacked the extra memory chip needed to store the bit corresponding to lower case.
The significance of this limitation has been exaggerated over time (it is worth noting that at that same time the Apple II also lacked lower case), but it created a real problem for word processors. Many lower case upgrades for the Model I were created to address the omission, ranging from simple to more complex.
The TRS-80 video display uses a dedicated block of 1024 bytes of memory located in memory space at 3C00 Hex. When received from the factory, there are only 7 memory chips installed in this block of memory, providing 128 possible characters for screen display. The stock TRS-80 uses 64 of these combinations for graphics and a second 64 for the upper-case subset of the ASCII character set. Bits 0-5 control the character selection, and the highest bit (bit 7) is used to determine if the character is alpha-numeric or graphic. Bit 6 is missing!
To add lower-case display, bit 6 must be implemented. This may be accomplished by switching the memory chip for bit 7 to bit 6, thereby enabling lower-case letters and eliminating graphics, or by addition of an 8th memory chip. We prefer adding the extra chip. In either case, if you plan to use Level II BASIC, you must include a switch to disable bit 6, or BASIC will place a lot of funny characters on the screen!

The Battery Acid has corroded some pcb tracks (not visible to the naked eye) connected to the pin of the resistor packs RP900 and to MC68000 and probably other IC.

Welcome back, Commodore Amiga 2000.
I do it very shortly, i don’t like writing a lot because i don’t have time to do and i don’t like it.
We are left with the Amiga 2000 that sometime works and sometime not.
Defect/Boot Errorr code was: gray / yellow / green / rainbow / out of sync / purple / white.
When this not happen, the boot works perfectly and i can see theusual “hand”
I have also replaced the socket of the MC68000 CPU and i have discovered another interruption between the pitche and track and also a lot of corrosion and recovered some connectors of an old Amiga 2000 REV 4 motherboard to give an decent aesthetic look to the repaired motherboard.
Now the Commodore Amiga 2000 works perfectly.

A big disappointing this Commodore SX-64 USA purchased for spare parts to fix aesthetically one of my SX-64 PAL.
Why disappointing? because from the photo’s looked in a very bad shape, rust stains, various diseases and not working.
Conversely after removed the shit from the external case, replaced the booring PLA (906114), general cleaning + keyboard / Floppy Drive test and replaced one keyboard lock, the SX-64 is fully working and aesthetically in good condition.
Now i have for myself four SX-64 where the fourth is NTSC/USA, but honestly i was not looking for the USA version.
I am really unlucky :D

CBMXfer is a front-end to several command-line utilities for transferring files and working with disk images. CBMXfer makes using those utilities easy by providing a familiar windows interface that removes the need to learn the commandline syntax of each program. CBMXfer also includes a multi-format file and picture viewer.
The commandline utilities are:

Jean-François DEL NERO (who’s behind the HxC SD Floppy Emulator) recently has released a version of the HxC emulator firmware that is compatible with the STM32 chip used in the Gotek floppy emulators.
This means that the great functionality of the HxC SD emulator is now available on cheaper and more widely available hardware.
The bootloader to convert the Gotek floppy drive in HxC compatible must be purchased on the website HXC 2001 by sending an email to Jean-François DEL NERO. The price of the bootloader is one-off 10 Euro per Gotek that you want to update. Future updates of the software are free and can be made from a USB stick
The HXC Usb (Gotek) firmware supports:
