put the card into your computer, you should make sure to set the jumpers properly. The jumpers are only for the SID chips, so if you're not planning to use a SID on your Catweasel, this step can be skipped. These jumper settings attach the capacitors to the SIDs that Commodore has recommended. The sound is nearly identical to the original computers C64 and C128. It's more common that statistical spreading between SID chips cause sound differences than capacitor tolerances, but we have chosen to use low-tolerance capacitors anyway. Note: The parts C39 and R5 are not assembled intentionally. 3 4 Audio-connector The output of the SID chips can be routed from the internal audio-connector to the line-in or the CD-audio input of your sound card. The internal audio connector on the Catweasel MK4plus follows the de-facto standard of CD rom drives, so a standard CD-rom audio cable should work. Unlike the previous version of the Catweasel MK4, there is no audio cable included with the Catweasel MK4plus. Instead, we have added an external audio connector with a 3.5mm stereo jack, which is commonly used in PC audio applications. Connecting an Amiga Keyboard The external PS2 jack can be used to connect an Amiga 4000 Keyboard. ● Can I connect an A2000/A3000 keyboard to the Catweasel MK4plus? Yes, this is possible with an off-the-shelve PS2 adapter for older AT-keyboards. These adapters are available commercially in PC-stores and mailorder-shops. ● Can I connect a CDTV keyboard to the Catweasel? The CDTV keyboard uses the same connector, but a different pinout for the connector. You will need to solder an adapter to connect the black CDTV keyboard. ● Can I connect an A1000 keyboard to the Catweasel? The A1000 uses a totally different connector, a 4-pin WD-modular, also known as a phone jack or RJ11 connector. The protocol of the keyboard is the same as for other keyboards, so the A1000 keyboard will also work with the Catweasel MK4plus with an adapter. These adapters are not available commercially, so you will have to make one yourself, if you have the necessary skills and tools.
