Hi Ctrix. Can you say what kind of SNES cart/mapper? Not really up on SNES mappers and such, but INL over at Nesdev.org has flash carts and a programmer, kind of like the Retrode edge programmer.
I already have the programmer for NES dev and getting a $20 SNES flash cart would be great. I know the release is still awhile out but if you have the target HW pinned down I can at least stare at the cart and drool

Hey guys! New account (not new user), but can anyone tell me about the process of getting one of those PSOne monitors/LCDs on my NES? And does the original composite video out stay intact? I've seen a couple examples, but I didn't really follow how they got it working. (Sorry if this is basic stuff.) Thanks in advance!
Funny you should ask, just talking 'bout LCDs with someone else. Yes should be fine. I've used one, as well as little portable 5" DVD player as a screen. Even found a 'in car' LCD screen. Very handy.
The PSOne screen I have has AV and Pwr inputs. Just need a RCA cable and a power pack.

New model to add:
Compaq Presario 1640.
This one has some neat features:
JBLpro Speakers
Tiny LCD display to monitor battery live and things
MAX ram is only 96 mb, but thats ok.
ESS AUDIODRIVE 1869, which is fully sb16 compatible.
Does the ESS chip ;emulate the OPL or is it a 'real' FM? I've got a 1625 that needs a HD, but had no idea it may be good for AdLib II. I'll have to spend some time sorting it out!

Replacing the main xtal would affect the PPU as well as the 2A03, and would mess with the timing of the video signal.

Very excited, over at AtariAge Freetz is working on a midi interface inspired by Littlescale's A26 teensy hardware
http://atariage.com/forums/topic/227037 … put-howto/
it's sounding very tasty! He just added ADSR to the note handling

TNK for the links, never knew they were also offering just cases. Can't tell if that second link is still valid, the links there are dead and the wiki said the company was all but shut down since 2012. Would of been fun to have one of those breadbox cases.

pretty cool, like the retro feel. Seems like awhile back there was a C64 breadbox miniITX, I think it was a production or pre-production model; not a case hack.

DIL socket sounds good!
I've never tried fixing cut PCBs... in fact I have a cracked Super Metroid and Yogi's story makes me want trying this method and restore the cartridge...
Anyways thanks for the good advice fellas
As long as you take your time and it's only a double sided board, bridge cracked traces with short lengths of 30 awg wire (wire wrap) for most signals and a heaver gage for power. Then clean with 90% rubbing alcohol and fill/overlay the crack(s) with 2 part epoxy on both sides.
The tricky part is if a section of trace/board is missing, just do your best to match up both sides of the missing trace. Kind of like a jigsaw puzzle If the damage is really bad well there may be no hope; but nothing ventured, nothing gained.

Frankly I do not understand how would you solder back a PCB trace. Indeed you could solder two ends of the cut trace with a wire but what do you mean by jumping a bit of solder? You mean one should scrub the PCB to expose the copper and then solder two parts of the cut trace? Because I don't see where the solder sticks to on this case....
I won't
The reason I'm asking is that no tutorial actually explains why should you *cut* the trace, so I was hoping that someone familiar with the schematic would give me quick answer. I think I'll look into the schematic myself and try to figure can I avoid cutting traces or not (I just don't like cutting anything on PCB). I'll keep you updated
- Yes, to jumper the traces you would have to scrape the green solder mask off of the copper. The reason you have to cut the trace is so that the original clock signal does not enter that pin. Your idea to pull the leg out and solder to your own clock is a fine idea too, but I would suggest pulling the whole chip out and adding a DIL socket.
You would risk breaking the pin off the IC; you'd have to do allot of bending to pull just one pin. If you'er dead set on not cutting a trace, I would de-solder the whole chip and then bend the pin.
With cutting a trace it's a simple job to restore it; the solder mask is very easy to scratch off. I've repaired cracked PCBs, bridging all the broken traces and epoxying the crack on the board. I had a monitor that lasted 10yrs after I rescued it

Re: Dreamblaster/Fluxamasynth GM voice (3 replies, posted in Other Hardware)
The db50XG is a daughter board for Waveblaster sound cards and can be fitted for stand alone like the MU10. My biggest road block is the price, though XG midi is sooo very good. Current listing for the card are higher then a used MU. The NEC XR 385 card is a db60XG clone and for awhile were available via ebay for about $50 but the NOS source seems to have dried up. These are def my first choice sound wise.
The best value I've found for XG midi are Yamaha YMF724 based sound cards for $15, but these aren't stand alone. There is an add bonus of an OPL core in these chips also, so there's FM fun there too 
The Dream Synth chip is a compromise of cost vs sound set, so for me, I can play with it stand alone without allot of cash.

Topic: Dreamblaster/Fluxamasynth GM voice (3 replies, posted in Other Hardware)
Hey all, This doesn't fit the 'chip' mold very well, more of a gray area like a retro/old skool game music sound. You decide
So for a long time there have been projects that use a WaveBlaster daughter cards as a stand alone General Midi voice, somewhat like a Roland MT 32 or a Yamaha MU 80 tone generators. I've wanted to build one on and off since I ran across these projects years ago, but just couldn't drop the coin on a nice db50XG card.
So just recently I learned of a (new to me) chip, the Dream synth SAM 2195 (was ASAM 2195) that is a compact midi voice!.
The first time I had run across the Fluxamasynth, I thought is was like the shields that use the VS1052 MP3/Wav/Midi decoder chip. The VS chip sounds ok but not great; good for a portable device but not for the studio.
Well I was wrong, very wrong. The Dream chip is sweet
Here's a sample from Wavetable.nl
Duke Nuckem 3D Intro
There are lot of examples there to check out
There is a Belgium company, Serdaco BVBA, is producing a Waveblaster board as well as a connector-less version.
DreamBlaster Synth S1
Stateside Modern Device has an Arduino shield, the Fluxamasynth, based on the Dream synth chip
Fluxamasynth
They are about the same price, $35 USD, so the shipping was the deciding factor for me.
Both boards are super easy to interface: TTL Midi in, Vcc and GND and BANG out comes stereo line level goodness. With 250 plus midi sounds (GM bank and MT 32 bank) And effects And filters, theres lots to play with. 32 to 68 voice poly depending on the effects used.
Here are some links to check:
Midibox.org thread
and
Electro-Music.com
So I'm off to build up an opto coupler Midi In and PSU so I can fire up this bad boy
Yogi
PS- the manufacturer has replaced the chip with a new model, so ATM prices for the boards have dropped (guessing till NOS is depleted). Hoping that boards will be redesigned for the new chip, but who knows.

Re: Help a beginner out. (23 replies, posted in General Discussion)
I would say to try out the PC trackers first, before dumping too much cash. Alot of the native tools for systems also run on PCs one way or another, so you can get a god feel for the workflow and sound.
You got some systems to start with, the
GB and DS are a no brainer to track on. A little harder for the A2600 and Genny, pretty much have to compile songs on PC for playback on those systems, but cound get a SynthCart for Atari and the midi kit.
Welcome aboard,

So from Google Translate
Because it is with much effort, so as to be able to save sounds,
I tried to model (OPM) FM sound source YM2151 incidentally. Tone that was possible and Pikokakiko, pattern made even SiON (or obvious)
So ummm... guess it's a YM2151 emu with midi input(?)

Re: .. (8 replies, posted in Other Vintage Computers & Consoles)
Well seeing as you won't sell 
(was just joking, you def got a good buy, hang on to it)
Judging from the pin count of the connector, I would bet it's based on the TI LPC speech chips.
Here is a page on the TI 99 speech module for some background,
http://nouspikel.group.shef.ac.uk//ti99/speech.htm
And the TI serial ROM chips datasheet
http://www.ti99.com/exelvision/website/ … manual.pdf
The ROM chip only needs 12 pin to interface so that matches with the Computron connection. It's a 4bit serial device.
Just guessing from the release date of '86; it might use the TI TSP50C50 which had the Speech synth, a uController and ROM on the chip. May be labeled CM54129 or 169
