These are some Sid examples which i have recorded from a Commodore 64 with the SwinSID installed. You can Download the original Sid track in .sid file format and the SwinSID in .ogg file format (High Quality), so you can compare the musics.

Some Sid tracks play perfectly others need some emulation fixes.

Micro SwinSID KIT by Peter Sieg:

Certainly you can’t expect perfect emulation, but we are very close, the audio is much more clean than the original SID chip, if the project continues on this road we will arrive very soon on the perfect emulation.

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.

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.

I continue to upgrade my Amiga 2000 PAL REV 4.5. I have upgraded the Kick Rom and added my Vector A2000i zorro Card with 4MB of fast memory.

I have decided to upgrade my Amiga 2000 PAL REV 4.5 for get 1MB of chip ram. I also took advantage of this update to install a new battery for the system clock. Amiga 2000 PAL REV 4.5 Fat Agnus 8372A Installation:

• Install a new Fat Agnus 8372A or 8375 (8375 R1)
• Look for jumper J101 beside the power connector to the motherboard. Change it to the opposite position. (photo)
• Look for trace J500 at the back of the machine near the Cia’s (8520′s). It’s a jumper trace that you will have to cut with a razor blade. (photo)
• Look for trace J102 near the Fat Agnus (8372A). It’s a jumper trace that you will have to cut with a razor blade. (photo)

from C64scene homepage:

Tomi Malinen is currently developing a dual SID board, although there are other solutions available for your C64 this one is interesting because of the ability to use either 6581 or 8580 as SID #2 no matter the board revision.

This means that you can play games with 6581 sound from the first channel and 8580 sound from the second.

Other features of the dual SID board are:

• Small board, only about 40mm x 50mm.
• SID #2 address jumper selectable between D400, D420, D500, DE00, DF00.
• MSSIAH-compatibility at DE00.
• Full game compatibility with double mono setting at D400.

Installation requires soldering, two wires attach to the cartridge port and two have to be soldered to the Kernal IC. When the SID #2 is mapped to D400, D420, D500 the wires to the cartridge port are not used.

My SIO2SD interface is dead (without any valid reason) after 2-3 hours of playing demos/games.

I have tried to reprogramming the firmware with a STK500 USB ISP Programmer and the tools AVRDUDE and it has worked perfectly.

The functions keys (Start / Option / Select / Reset..) of my Atari 130 XE not making good contact, i have fixed this problem with a good clean-up and graphite of a pencil.

Foto review of the Serial cable and Transfer program:

ADTPro may be used to transfer Apple diskette/disk images in DOS or ProDOS/SOS format.

The Apple client side happens to run under ProDOS or SOS, but it is perfectly capable of reading or writing Apple DOS (or Pascal, or CP/M, or…) diskettes.
