nice loop! what is your monitoring system for mastering? (it is subjective but it seems like too much compression for my taste)

sorry, i was not sure if you would choose the smd eeprom or fit the pcb for the dip version.

hi nils, why the eeprom 24c04 is flying? there is no enough space to include the dip version?

Je viens de regarder le datasheet des switchs... pates 3.5mm (on ne compte pas), embase 3.5mm et puis après le capuchon c'est de taille variable... donc pour un total de 13mm, il ne reste que 9.5mm de hauteur pour le cylindre. Donc effectivement, c'est le modèle 9.5mm :) Merci, j'aurais fait l'erreur.

Je m'en suis pas encore acheté... pas le temps. Mais je récolte toutes les adresses pour les différentes pièces : http://cgi.ebay.fr/Tactile-Switch-F16-6x6mm-H-13mm-Lot-of-100_W0QQitemZ330280842408 ... vérifie quand même si c'est bien compatible, il me semble que oui.

It is briefly explained in the technical details of http://en.wikipedia.org/wiki/MOS_Technology_SID

Some no-news about the noise problem. Microchip tech service was unable to find a reference datasheet for their version of the ay-3-8912 chips. And in other way, Sergey Bulba ( http://bulba.untergrund.net ) never met that problem... he gave me the email of another guy but i still did not contact him however. I have the soundchips in a shoe box but not enough time for now to build the synth :-\

got the package yesterday. thanks

come back to the initial subject... snes has an apu (audio processing unit) :( a lot is explained here: http://www.raphnet.net/electronique/snes_apu/snes_apu_en.php

Hi everyone, As I do not have any C64 power supply unit, I am looking for another solution. Jsaily from Lemon64 forum is making a clone of the C64 PSU... here are the links to the forum thread and schematics: http://www.lemon64.com/forum/viewtopic.php?t=27552&start=105 http://www.netsonic.fi/~kelpf25b/C64-PSU.zip What do you think about? :D edit: i forgot to mention -> using an external 20ac/9ac output transformer image: http://www.netsonic.fi/~kelpf25b/IMG_1090.JPG

I just receveid mines. Thanks!

bad news from radiospares france... since march 2008 they only sell to professional customers :-\

Not finished mine. But are you talking of J7 5v OUT ? from usb power as explained at: http://www.ucapps.de/mbhp_usb_gm5.html

Hello, Une variante de midibox lc ? http://www.ucapps.de/midibox_lc_fr.html Ton copain sera utile pour la soudure... pas tout à fait pareil que monter un pc ;)

That is the fact... due to the lack of information on the Internet, I hoped there was a sound generator chip AND an additional pcm chip. SO not an interesting sound chip :-\

Short auto-reply... that texas instrument chip seems to be as similar as the 2 sony 3430045B chips (found in the se/30). Maybe a production under license for a stereo model. So... the "apple sound chip" family is 343-something chips and 343S-something for stereo version ;)

Hi, I just opened a mac lc630 and was looking for the soundchip... i found nothing on the internet about that chip ??? I just know that the ASC "apple sound chip" is inside all mac models from mac 2 to mac 660 except in quadras with the introduction of the EASC "enhanced apple sound chip" (same but adding a pcm output with a sony-built sound chip )... that apple sound chip is very popular :) It seems to be 8 bits, 4-voices, wave table synth, stereo generator. http://www.ozonehouse.com/mark/cv.html Mark Lentczner worked on it. On the motherboard, I suppose that the apple sound chip is TI 4BA2E9W 343S0129-C, isn't it?

I tried to find some czech <-> english online translator but it was not very usefull... http://www.tranexp.com:2000/InterTran?type=url&url=http%3A%2F%2Fvelesoft.speccy.cz%2Fturbosound-cz.htm&text=&from=che&to=eng :P so I only read schematics ;)

There is no reference to the turbo-sound project: http://velesoft.speccy.cz/turbosound-cz.htm The goal is not similar (improving sounds in a zx spectrum)... but the schematics are interesting. edit: turbo-sound example http://velesoft.speccy.cz/turbo_sound/inbeatwin_demo.mp3 (warning: lot of noisy waves)

I follow you with 8 of them. I dunno what do to with yet but you caught the cheapest way.

Hi, I am interested by the whole thing including leds and programmed pics. If you agree to ship the package to France! I have to see the different parts I need to their related projects. Matthieu

Unfortunately your picture is from a classic zx spectrum without any soundchip and not from the 128 version with the ay-3-8912... but it is still soldered! you can see that chip on: http://mpc.fab.free.fr/sinclair/pzxvszx.htm

4$us = 2.7euros. I do not know if the chip I will receive is still working. I could take 8 of yours (and next I will see what to do with :) ... is there a better deal in Australia?
