I now have the latest revision of my Quazar Surround soundcard (which gives the SAM Coupe some rather extensive sample playback capabilities - six sound channels and surround sound outputs!) listed on eBay. It's also on my quickshop page with options for floppy disk or SD card for the introductory software.

I got an old PC but without a PC Speaker, so I did the only sensible thing anyone would do... Making my own PC Speaker sound card, ScreechyCat.

ScreechyCat is a heavy contender for the title of worst sound card ever, but it is retro, it kinda works, and it is dirt cheap to make.

And in english, a page by AMSAT-DL about the #qo100 #soundcard #hsmodem by #dj0abr : https://amsat-dl.org/en/qo-100-high-speed-multi-media-beacon/

QO-100 High Speed Multi Media Beacon

The new "AMSAT-DL Highspeed Multimedia Modem" developed by Kurt DJ0ABR for the QO-100 NB transponder allows a transmission speed of up to 7200 bit/s in 8 APSK or 4800 bit/s in QPSK despite the maximum allowed bandwidth of 2.7 kHz.It is thus significantly more efficient than conventional methods on
