This is a quick demo using a feature of PCMCIA, allowing low quality audio to be fed directly to the computers PC Speaker. This was intended for modems to be able to output sound for dialing and connecting but there are a few soundcards that had this ability.
In the following list you can see some cards with the note “Outputs to PC Speaker). Soundcard List – GoogleSheet
The quality will vary between systems depending on how they implemented the internal audio. We will be able to use the EQ on the DSP to try and further optimize the output to get the best possible quality between systems.
Hello, I’ve been following this since I reserved early. Great work — I know this must have taken a lot of effort.
I’m wondering whether the internal speaker audio method you described can also be applied to the IBM Palm Top PC110.
thank you for your support! It absolutely works on the PC110! It will even work on the HP200LX! It has pretty universal support because of modems.
This is truly impressive. Thanks to your efforts, the PC110 will be perfected. I sincerely look forward to the results.
