Hi:

I'm thinking of building my own version of the OPL3 FM synth chip without the use of frail devices. I would like this OPL3 replica to fit all the following characteristics:

1. Does not need any soldering to build

2. Is easy to physically carry around

3. Can withstand temperatures extreme enough to destroy the original OPL3 chip

4. Can withstand physical stress [such as from accidental falls] without experiencing any damage

5. Does not contain or require the use of any hazardous material [such as UV light and chemicals] for construction or operation

6. Can withstand static electricity without being damaged to any extent

7. Can withstand -- but does not use -- amperages high-enough to instantly destroy the original OPL3 chip ithout being damaged to any extent

8. Can withstand -- but does not use -- voltages high-enough to instantly destroy the original OPL3 chip without being damaged to any extent

9. Can withstand -- but does not use -- wattages high-enough to instantly destroy the original OPL3 chip ithout being damaged to any extent

10. Can withstand square-waves [e.g. clipped waveforms], spike-waves, triangle-waves, and other sharp-edged signals intense enough to immediately obliterate the original OPL3 chip without being damaged to any extent

11. Can be submerged in water without being damaged to any extent [even while running]

12. Can withstand short-circuits without being damaged to any extent

13. Is small enough that it can be easily washed in the average household bathroom sink

14. Can be vigorously cleaned with water and dried with any towel without experiencing any damage.

15. Can be disassembled and reassembled without being damaged. This is in case #13 is not possible. If #13 cannot happen, then I can wash and dry each component after disassembly and then reassemble the OPL3 after all the parts are clean and dry.

Is is possible for me to build my version of OPL3 device given the state of today technology? If not, what is the closest I can get?


Thanks,

Green Xenon

- Find small microprocessor based board that fits your criteria - probably something based around an ARM cpu. (ie a cell phone without the cell phone)
- Port the MAME OPL3 emulation code to the target os/cpu.

Not too "cool" but it's the most realistic option IMHO :D
