A new version of the firmware for the interface 1541 Ultimate I / II is released.
This version also runs on the Ultimate-I! (Of course, only the features that MK1-hardware supports will show.. no RTC, no USB, no C2N (tape), etc…)
Some major fix:
- Freezer bug fixed.
- Cartridge Freezer reactivated after DMA load.
- MK1 support completed.
- Tiny fix added for USB (connecting a powered hub caused the C64 to be powered by the hub!!)
- Updater fixed for older FPGAs that don’t support the capability register.
- Memory controller for MK1: removed DACK for write cycles.
- Added dummy I/O clients, for missing modules in MK1 FPGA.
- Rewritten first bootloader (…)
- Added second drive support in software.
- Added audio switch. If second drive is available, it will be available on the right channel.
- ‘Chars’ linked instead of loaded from Flash. MK1 doesn’t have charset in flash…

Many thanks to Nilo for the Monitor.
This is the 9″ monochrome CRT display for Apple IIc, and the stand! Both are in great shape and the monitor works very well.
I wanted to try my new desoldering station Aoyue 474A+ with the motherboard of the Commodore 64, i have unsoldered all chip and i have added a socket. It works so good and is so fast.

Today i picked up a Commodore 1541 Single Floppy Disk with serial IEC / Powersupply cable, Manual and Test demo Disk in original Box and in good working condition.

SD2IEC is a hardware mass storage device using an SD/MMC card and interfacing with the IEC bus. It is based on the ATmega644 microcontroller from the Atmel AVR microcontroller family.
The most prominent use of SD2IEC is emulation/replacement of a Commodore-1541 disk drive for a C64. Hardware and the microcontroller’s firmware is available as open source (GPL).
Changelog:
2010-10-16 – release 0.10.0pre3
- Bugfix: Wheels 128 loader detection fixed.
- Bugfix: G-P answer fixed.
- Bugfix: Strip 0x0d from file names when appropiate.
- Wheels support.

A backup machine is having issues at the moment, which is adversely affecting multiple MySQL machines.
The root problem has been resolved, and most of the cleanup is done…however, if you’re still noticing any lingering MySQL issues, let us know, and we’ll be happy to address them as needed.
Again, sorry for the downtime.

Here you can see some photo of the first version of the 1541 Ultimate II tape extender. With the latest firmware it’s now possible capture tape data to a .TAP file!

Micro SwinSID (SwinSID88) is a hardware replacement for legendary SID sound chip which was placed in every Commodore C64 computer.
This project is based on the microcontroller ATMEGA88PU from Atmel and the emulation code is written by Swinkels. The first version of the pcb (prototype) was made by Crisp.
On the left you can see the tiny PCB of the Micro SwinSID made by a user of the forum64.de.
*This PCB is compatible with Commodore 64 and 64C but you need to Remove the resistor R3 if you install the Micro SwinSID on Commodore 64/SX64 where the SID 6581 is used.
For more information and price visit the forum64.de.
A new version of the firmware for the interface 1541 Ultimate II is released.
Some major fix:
- Some debug stuff that appeared in menu removed!
- Tape Record implemented.
- Capabilities register added (for V1 compatibility later)
- Initial version of memory controller for V1 hardware added.
- Global menu items replaced by menu objects that can generate menu items based on the object’s state.
- Some bug-fixes.
- Christmas lights eliminated in many places.
- 64K AR/RR Ram support added; as well as made to pass CountZero’s test program with 71 points.
- Freezer bug is NOT yet tackled.
- Preliminary USB hub support added (not finished)
- Tape recorder software file created, but is still a copy of playback. Needs to be implemented.
- IEC processor implemented.
- Some clean up done in USB code.
- C2N Recorder added to Fpga makefiles. (not for 250e yet)
- TAP Encoder added.
- ZPU altered for guaranteed IRQ handling (not used yet)

Micro SwinSID (SwinSID88) is a hardware replacement for legendary SID sound chip which was placed in every Commodore C64 computer.
This hardware extension is designed as a module installed directly into the SID socket. It emulates the sound of the SID chip, but it is a lot more powerful and allows you experience the new dimension of C64 music.
The hardware desing of SID and Micro SwinSID (SwinSID88) modules is different in almost every way. Micro SwinSID (SwinSID88) is equipped with general purpose microprocessor (ATMega88PA or PU) with internal RAM and ROM.
A programmable device like this has a big advantage – there is a possibility to upgrade firmware and to add new features or fixes without any hardware modification.

The Commodore 6499 is a modem made by Celint for Commodore in Italy. It was able to connect the Commodore 64 with Sip Videotel. Sip Videotel (now Telecom Italia) was unique telephone company in Italy that provided a sort of BBS with teletext.
The modem could transmit at 300/300 baud on BBSs, and 1200/75 baud on Videotel/Minitel.
