Assembly and Replacement of the old DualSID with the MixSID

Assembly and Replacement of the old DualSID with the MixSID

Assembly and Replacement of the old DualSID with the MixSID.

Unlike the DualSID i had to replace the two electrolytic capacitors (see picture) because the PCB of the MixSID is much more big and the two capacitors hinders the right installation of the PCB in the SID socket.

Ultimate-II+

September 30th, 2016 No comments
Ultimate II Plus

The ‘Ultimate II+’ is a storage solution for your Commodore C64/C128(D) home computer or in stand-alone mode for C16/Plus4/VIC-20 and so on.

This cartridge implements a ‘real’ 1541 Diskdrive for Commodore computers and with a simple press on one of the buttons, a menu will pop-up on the Commodore screen, allowing the user to view the USB storage content, and ‘mount’ .d64 or .g64 images into the Floppy Drive.

These are the most important differences from the previous version of the cartridge (1541 Ultimate-II)

  • No more MicroSD! (… that needs to be pushed in with something sharp, could fall into the case, … etc)
  • More USB ports (… one to compensate for the lost SD, and just one bonus: 3 in total)
  • IEC connector moved (… further back to facilitate use on some C128 models)
  • Integrated Ethernet (… no more need for an external USB2LAN adapter, and a smaller step to CS8900A compatibility)
  • Dual Flash (… no more worry that a software bug or upgrade failure leads to a bricked device)
  • Integrated Speaker (… who connects a speaker set to the audio jack for hearing drive sounds??)
  • External power supply connector with auto-switch over circuit (… for stand alone mode, and to lower the demand on the power supply of the C64)
  • Improved Audio (… audio codec, 24 bit/96 kHz*, for sampled sounds and SID emulation)
  • Improved Tape connector (… no more custom board and able that snaps in on the bottom, but standard USB 3.0 cable)
  • Improved power supply circuits (… for some reason they seemed to break down relatively often)
  • Slightly bigger and faster FPGA, as to control the new features.

TekTronix DS1000G (NTSC version) Television Demodulator

TekTronix DS1000G (NTSC version) Television Demodulator

The television demodulator can demodulate M/N standard television signals to baseband video and audio. In addition, the DS1001G provides the capability of recognizinga GCR signal and applying
correction to the baseband video output.

TheDS1001A/DS1001G covers the tuning range of 55.25 to 801.25MHz. The high performance of the conversion guarantees a measurement-quality signal after demodulation.

1541 Ultimate II +

June 11th, 2016 No comments

…from the author website:

Since the end of 2015, it became clear that the “good old” 1541 Ultimate-II was at the end of its life cycle. Xilinx, the manufacturer of the most important chip of the cartridge, had started to increase the prices of the chip. Also the memory chip started to be harder to get and at higher cost. When the news came that the company that made the black plastic cases for the 1541 Ultimate-II had lost the injection mold tool, it became evident that the 1541 Ultimate-II would be no more.

I have given it some thought. What would be the best way to continue with this project? When the feelings of being upset about the lost injection tool had subsided, I realized that this may be the perfect moment for an upgrade. This is when set backs change into opportunity.

Since then, a lot of work, and I really mean A LOT OF WORK has been done to create a successor: the “Ultimate-II+”.  Why not “III”, you may ask or think. Well, the foremost reason is the software. The install base of the “1541 Ultimate-II” is rather large (>3000 units), and I do not want to let my customers down that have just purchased a unit. This means that in case of new hardware, the same software should run on both the new board, as well as on the older board. So, the new board will offer similar functionality. You could see it just as an upgrade, not an entirely new product.

Although the “Ultimate-II+” is similar, there are also differences:

  • No more MicroSD!  (… that needs to be pushed in with something sharp, could fall into the case, … etc)
  • More USB ports (… one to compensate for the lost SD, and just one bonus: 3 in total)
  • IEC connector moved (… further back to facilitate use on some C128 models)
  • Integrated Ethernet (… no more need for an external USB2LAN adapter, and a smaller step to CS8900A compatibility)
  • Dual Flash (… no more worry that a software bug or upgrade failure leads to a bricked device)
  • Integrated Speaker (… who connects a speaker set to the audio jack for hearing drive sounds??)
  • External power supply connector with auto-switch over circuit (… for stand alone mode, and to lower the demand on the power supply of the C64)
  • Improved Audio (… audio codec, 24 bit/96 kHz*, for sampled sounds and SID emulation)
  • Improved Tape connector (… no more custom board and able that snaps in on the bottom, but standard USB 3.0 cable)
  • Improved power supply circuits (… for some reason they seemed to break down relatively often)
  • Slightly bigger and faster FPGA, as to control the new features

Flashing 2 x Gotek floppy emu with HxC firmware w/ Track Audio

October 29th, 2015 No comments

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:
