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:

Release notes Firmware USB HxCFloppyEmulator v3.0.6.4a

• Random crash issues corrected into the disks images managers.

Release notes Firmware USB HxCFloppyEmulator v3.0.6.3a

• Some user interface delays added to make it more usable ;)
• “Press select for the Setting menu” text added.

CBM prg Studio Version 3.4.0 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:

• Assembler:
  • Dump file.
  • Visual Data Generator tool.
  • Directives for creating tabular data.

• General:
  • Mixing BASIC and machine language in same project.
  • More control over IDE colours.

Bugs Fixed:

• Assembler:
  • Wrong start address when saving from the memory window.
  • TEXT and PTEXT generating wrong character values.
  • “
  • Binary import as assembler was using the wrong start address.
  • Incbin problems with large files.

I have received two Computer Apricot F1e without accessories and aesthetically destroyed so i have decided to recover all that was possible.

This gallery shows some stages of the repairing of the Floppy Drives of the Commodore SFD-1001 & Commodore CBM 8296D.

Defects found on the Floppy Drives:

• Floppy drives had the capacitors that leaked acid on the motor control pcb.

The difficulty was rebuild the tracks of the pcb and remove the most of the leaked acid of the capacitors. Unfortunately on the aesthetic level this type of repair are not perfect, but i’m glad that all drives now work.

To test the correct operation of the Floppy Drives i have used a working SFD-1001 with a ZoomFloppy Interface through the IEEE-488.

Replacing bad capacitors (Floppy Drive #1):

Replacing bad capacitors (Floppy Drive #2):

Replacing bad capacitors (Floppy Drive #3):

The reason of the replacement is the leaky capacitor.

The Aluminum Electrolytic Capacitors (SMD) used in these machines eventually exude their conductive contents onto the mainboard causing short circuits and corrosion of the pcb tracks.

Replacing the capacitors on an Apple Macintosh Classic II:

As you can see from the first photo i had to replace the cathode ray tube (CRT) of a Macintosh SE/30 because has a “ghost image”.

The replacement is very simple but you have to replace also the deflection yoke because the yoke connector is different between Classic and SE/30.

The replacement of the deflection yoke obviously also involves the calibration of the image. The calibration of the image is not  simple and should be done with the computer on. Be careful there are very high voltages on the cathode ray tube (CRT).

Gallery of the replacement:

The DK’tronics keyboard for the Sinclair ZX Spectrum is a sturdy, solid-looking, black ABS case with a set of grey alphanumeric keys on the left and a 3×4 red numeric keypad set on the right.

The Spectrum is removed from its case by unscrewing the case halves, gently pulling out the two keyboard connecting ribbon cables and unscrewing the two small circuit board screws. The reverse process is then undertaken with the DK’tronics keyboard. Precise instructions are supplied so any incompetent can do it – even I managed !

The keys have a pleasant feel to them, the spring pressure was just about right to allow for my fumbling efforts, and generally the legends supplied on transparent stick-on plastic labels, are easy to read.

Below a short description of the repair.

Commodore PET 2001 (1977) Chiclet Keyboard (#1)

Defect:

• Garbage Screen on boot and partially in a working state.

Diagnosis/Repair:

• The Multiplexer 74LS157 (position D2) had an output (pin 4) always been in low state.

Gallery of the repair:

Commodore PET 2001 (1978) Chiclet Keyboard (#2)

Defect:

• Garbage Screen on boot.
• Memory Problems (1018 Bytes are missing)

Diagnosis/Repair:

• The garbage screen on boot was caused by a poor contact of the sockets where reside the ROMs. Temporarily fixed by inserting a precision sockets above the original socket (very bad quality sockets).
• The problem of the missing memory was fixed by replacing a RAM MPS 2114 (position J1) with a new one.

Ikari has released a new firmware for the SD2Snes Flash Cartridge (Super Nintendo/Famicom). The upgrade instructions can be found here.

Download: SD2Snes Firmware v0.1.7 Beta/Preview Rev 4 (1393)

Full Changelog:

• Prevent software from using uninitialized DMA ch.0 transfer to corrupt the stack (fixes Nightmare Busters)
• Disable PPU region patching during the menu
• MSU1: Stop audio playback on reset (fixes static buzzing noise in games after soft-resetting out of an MSU1 game)
• Cx4: Add a switch for original/fast mode. “Original” mimics the Cx4 timing better (Megaman doesn’t die in MMX2 attract mode) whereas “Fast” uses a single CPU cycle for every instruction, improving frame rate when drawing polygons (rotating head in MMX2 intro).
• Hide dot files and directories again (Regression in 0.1.7).
• “Stealth Mode” for in-game hook memory area hides the memory region used by in-game routines from games. (Fixes Equinox, Lion King)
• In-game hooks are a bit less intrusive in terms of CPU time, hopefully reducing glitches a bit with problematic games.
• System Information screen shows file system usage on card.
• Slow down DSPx a bit to better match original speed (should have no noticeable effect)
• Font height is reduced by one pixel to increase readability (lines of text are more distinguishable). This has an effect on the font style so some might not like it…?
• Background is greyed out when a window is active in foreground
• Menu now uses the dynamic hierarchical menu system, with automatic calculation of window dimensions, etc. Not much of it can be seen at the moment due to the lack of menu entries.
• Experimental SRAM mapping for Cx4
• FPGA: adjust address sampling time for “end-of-cycle” events. Should help primarily with DSP1 glitches.
• MSU1: initial volume now adheres to the latest spec (initial volume = 0) so it must be initialized by software to the desired level. This actually breaks my own example player I will post an updated version of it shortly.
