Media Vision Sound Card/CD interface
by Neil Cherry 30 Jan '23

30 Jan '23

Anyone interested in a PC Media Vision Sound Card. last used ??? Yes, I've been going through my stuff looking for my EPROM burner manuals. I'm finding all sort of interesting 3COM network cards (16 bit), serial/parallel/ Game/FDC cards (16 bit). I still haven't found my second manual (grrr). Did find one of my 6809 card I worked on in the 1980's :-) -- Linux Home Automation Neil Cherry kd2zrq(a)linuxha.com http://www.linuxha.com/ Main site http://linuxha.blogspot.com/ My HA Blog Author of: Linux Smart Homes For Dummies KD2ZRQ

Ideas for VCF 2023 t-shirts
by Jeffrey Brace 30 Jan '23

30 Jan '23

I'm starting the process for ideas and a design for this year's t-shirt. If anyone has any ideas that they want to throw to us, then please do so by replying to this email either publicly or privately. Keep in mind that we may not use your idea, so don't feel disappointed if we choose another. One t-shirt that was really popular was the "dragon" t-shirt which had the IBM 5150 running Adventure and a dragon on the side. Perhaps a similar iconic creature would be popular with people.

That idea has potential. I like it.

(off topic) - options for smaller than 19" receiver/amp for multiple RCA connections?
by John Heritage 28 Jan '23

28 Jan '23

Hey folks, Just wondering - I have multiple vintage devices sharing an old 19" Onkyo receiver. It works great but takes up a lot of desk space. If I replaced it with a smaller amp (that I could mount under a desk) what are some options for hooking up multiple RCA cables and switching between them? Would appreciate links to example devices. (Fwiw - currently I keep an Amiga, an ST, and a Sega Genesis attached but only use sound on one at a time. May add a 4th device later). If you're linking something with an amp (which is cool) my power requirements aren't huge. 40w RMS would be ideal. Thanks! John

I had some time tonight. I updated the VCF East 2023 Exhibitor List. There are 20 exhibitors so far. We still have plenty of room for exhibits. Deadline is March 24 for exhibits. Keep them coming!
