nowy80 Posted October 10, 2021 Share Posted October 10, 2021 I invite you to watch the material as Atari loads the game from a vinyl record. I use the Technics SL-1900 turntable as the sound source (1978). See for yourself how Atari deals with mechanically generated sound and interprets it into program code https://youtu.be/waG2akcMuIA 12 2 Quote Link to comment Share on other sites More sharing options...
xxl Posted October 10, 2021 Share Posted October 10, 2021 As the sound engineer explained, the sound found on vinyl provides a nicer, warmer sound for your ears and your Atari. seriously - Great idea. 1 Quote Link to comment Share on other sites More sharing options...
Rybags Posted October 10, 2021 Share Posted October 10, 2021 So I take it the SIO interface we see around 2:30 has the demodulation circuit similar to a 1010 tape drive? 1 Quote Link to comment Share on other sites More sharing options...
ivop Posted October 10, 2021 Share Posted October 10, 2021 Be sure to use gold plated monster cables for an even warmer experience! Nice SIO interface! Any schematics? 1 3 Quote Link to comment Share on other sites More sharing options...
nowy80 Posted October 10, 2021 Author Share Posted October 10, 2021 (edited) I love the sound of a vinyl record. It is very warm and palpable. I have a turntable connected to a tube amplifier. The sound of loading the game is also very pleasant and vivid. The SIO sound interface was produced by Piotr Bugaj from Poland. It is a device that converts the audio signal from RCA to SIO (mono). I used a cable for my bass guitar. Any real copper will work and has no effect on creating the sound Edited October 10, 2021 by nowy80 Quote Link to comment Share on other sites More sharing options...

Should have put a smiley behind it Edit: Is that interface available for sale somewhere? Would be nice if it also supported stereo and replay the non-data side on SIO audio in, but by the looks of it, it is mono only.

nowy80 Posted October 10, 2021 Author Share Posted October 10, 2021 I sent the link of our conversation to the developer of this solution. Probably Piotr will write something more about his solution. 1 Quote Link to comment Share on other sites More sharing options...

Any schematics? Here is a thread about a similar interface with schematics, it shouldn't be too hard to also connect the other channel to the SIO audio input if desired(it would probably need to be amplified).

Rybags Posted October 11, 2021 Share Posted October 11, 2021 They've put an article about this at Atariteca https://www.atariteca.net.pe/2021/10/cargan-juegos-de-atari-8-bits-desde.html Nice that they keep up with current events, now if only they'd fix the text contrast on their website. 2 Quote Link to comment Share on other sites More sharing options...
Fred_M Posted October 11, 2021 Share Posted October 11, 2021 So you created and ordered one copy of the record. That is quite an expensive hobby Looking at the strobe of the record player, it runs a bit too fast. Did you that intentionally? Quote Link to comment Share on other sites More sharing options...
Rybags Posted October 11, 2021 Share Posted October 11, 2021 It sounds a little bit faster than normal rate SIO - the system auto adjusts and can handle higher speeds to a point, with the benefit of faster loading time. So maybe he did it for that reason. Quote Link to comment Share on other sites More sharing options...

Many thanks! Please, could you send me a screenshot of the text issue via PM? And, in order to not derail the topic, I'd like to ask Pawel if the record was a "single" or LP.

Rybags Posted October 11, 2021 Share Posted October 11, 2021 12" at 45 rpm is usually called an EP. Generally they were 9-12 minutes of music on a side if I remember correctly. Though the amount of music you'd get on a record would be pretty variable. A studio album would be usually 4-5 songs a side so 20-25 minutes but you'd get those compilation ones where they'd cram 15-20 songs on and they'd usually go closer to 40 minutes a side.

Fred_M Posted October 11, 2021 Share Posted October 11, 2021 (edited) In Europe EPs were also made on 7 and 10 inch vinyl. I have several in my collection. Edited October 11, 2021 by Fred_M Quote Link to comment Share on other sites More sharing options...
nowy80 Posted October 11, 2021 Author Share Posted October 11, 2021 Thanks to Rybags for the link and the article. I am sending a turntable sound sample recorded by a grabber connected to the Atari. I got some questions about the production of this vinyl for Atari collectors. If 10 people gather, they will be happy to carry out such production. It will be cheaper than my single disc. If they were interested, please give me a private message https://www.szybkiplik.pl/9M3NHXGX3Y Quote Link to comment Share on other sites More sharing options...

In The Netherlands, one that presses vinyl for volumes as low as 50: https://www.centraalmuziekhuis.com/vinylpersen/ €16,90 with full color artwork, if you order 50 pcs.

(The Belgian cutter). Their prices include a full color cover and center labels. 300 dpi, 3720 x 3720 pixels. Perhaps we should create a remake of the megacd project, with the option to swap left and right (similar to the current design), or to feed right to SIO audio-in. That way, you can either cut a mono track of your favorite band as the right channel while loading, or (similar to the megacd project), you can have two games at each side. One on the left channel, one on the right. Edited October 11, 2021 by ivop 1 Quote Link to comment Share on other sites More sharing options...

ivop Posted October 11, 2021 Share Posted October 11, 2021 I also checked our friend Ali from China. Pressing costs about the same. $17 dollar a piece, but with a lead time of 30 days. Cutting can be cheaper, but only at 50 pieces or more. $4.19 a piece, including customized packaging. 1 Quote Link to comment Share on other sites More sharing options...
nowy80 Posted October 11, 2021 Author Share Posted October 11, 2021 I have realized my orders many times only in Europe with a guarantee of performance. I have never had a plate cut from China in my hand. Quote Link to comment Share on other sites More sharing options...

Level42 Posted October 11, 2021 Share Posted October 11, 2021 (edited) I must be a chagrin but I totally fail to see the point of this. And I'm a vinyl lover........ for music. I have a pretty sizable vinyl collection and pretty decent audio equipment. Then again, I also completely fail to see the "charm" of loading stuff from cassettes. I guess in my youth I was too envious of 1050 owners for too long.... Edited October 11, 2021 by Level42 Quote Link to comment Share on other sites More sharing options...
