tecnobytes are starting a new campain to produce a new OPL4 Shockwave batch, the OPL4 Shockwave 2!

This new product will come with the same quality as always, but some differences and new features:

  • Design
    The OPL4 SHOCKWAVE 2 is smaller than your predecessor and fits in a small cartridge case.
  • Output
    As the new size will not accept the RCA connectors, now it have a P2 stereo output.
  • More Output
    The OPL4 sound is mixed with the internal MSX sound. So you can listen the OPL4 Shockwave 2 sound through the MSX sound output (mono).
  • More Memory
    The OPL4 SHOCKWAVE 2 have twice the RAM capacity of the original SHOCKWAVE (2MB against 1MB).

Let´s talk about the new batch:

  • tecnobytes need at least 20 units to produce.
    So, if this minimum can't be reached, they will cancel the project and return all payments;
  • tecnobytes will start to buy the parts and send the PCB for manufacturing as soon as it reaches 20 units;
    The timespan, from buying all parts to sending the cartdriges, would be from 2 to 3 months. There are many factors, like customs and couriers. tecnobytes mentioned they will keep everyone informed;


  • Each OPL4 Shockwave 2 cartridge: US $ 135.00
  • International shipping: US $ 38.00 (tecnobytes can send up to three units per package - please send an email if you want to buy more than three cartdriges)
  • Paypal fees: 7.5%

That's quite a beast. I don't think you have anything to worry about. I haven't seen an opl4 cartridge with that many options yet. Sound quality is great as well.
