SIDblaster/USB is a portable PC SID-synthesizer. Hook it up to your USB-port and you’re good to go. It is designed to work with a MOS 6501 SID. If you need to use a 6500 or 6502, the RNM-0512S needs to be replaced by a 5V to 9V DC-DC regulator.
SIDblaster/USB is partially HardSID-compatible (under Windows) in the sense that it can be used in many programs that support the HardSID by the means of a hacked hardsid.dll. Compatiblity has been verified with SidPlay2, SidPlay2/W and GoatTracker.
The decoupling capacitors (the grouped 100nF, 10nF and 4.7nF) should be connected near their respective circuits:
- 100nF: FT232R
- 4.7nF: FT232R
- 10nF: PIC16F86
Two examples of compact pcb solutions (left: hole mount right: surface mount) that can be mounted in a small case. The AUDIO port needs to be wired to a suitable connector, for example a 3.5mm audio jack. The card is intended to be mounted in a case with tracks for the PCB. The height of the card needs to be adjusted to fit different cases. On the left hand side of the PCB is a USB-B port. You’ll need to open up a rectangular hole in the case for this port to slide through when the PCB is inserted.
Compact hole-mount solution. Verified, functional!
Ultra-compact SMT solution, only ~50% larger than the SID-chip. Not verified!

- Not critical, may be bridged. Used to remove high frequency interferance.
- May have suitable replacement.
- Is a 1x40 header that should be broken into two 1x3 headers to replace the 2x3 header.
- Is a 1x40 header that should be broken into two 1x14 headers that will hold the SID.
Need to know
The PCB layout is missing a restor on the ICSPHDR between the VPP and VDD pins. This resistor MAY be needed for ICSP-programming using a programmer that requires external MCLR (ICD3 for example). The resistor should be between 1k and 10k (see programmer documentation), 4k7 worked well in our case. The resistor is only needed during programming, once programmed you can bridge VPP and VDD using a jumper. If internal MCLR is used, no jumper or resistor is needed.
Several of the capators in electrokits online catalogue are incorrectly marked in regards to pin spacing. All capacators should have a spacing of 2.54mm, allthough 5.08mm spaced capacators can usually be bent so that they’ll fit.
Depending on what version of the PCB-layout you have, it’s possible the the DC-DC regulator will not fit. This has been corrected in later revisions of the layout. The legs of the regulator can be bent so that they can be connected using a piece of wire.
During shipping (using swedish postal service in a padded envelope) of the first SIDblaster from Sweden to Åland the SID-chip became dislodged from it’s socket. Apart from this and the fact that the CD was crushed it was in good shape upon arrival. If your SIDblaster is to be transported or otherwise roughly handled you might want to consider locking the chip down in some way.
If you are interested in the Windows software (hacked hardsid.dll with MinGW source), PIC firmware (.hex or assembler source) or gerber and excellon files for PCB manufacturing – you can contact me at the hotmail address “senseitg”. Either that, or you could drop by the research department next tuesday!
