the ii series outputs composite

cool, not too far from my home town

good thing about sega boxes is that they are plastic clamshells and not that much thicker than the cart (though taller and wider), unlike most systems where you get a roach hotel crap cardboard box that does little but get squished up, the plastic boxes help the market as its more likely to be in really good condition and with manual that being said there is a local game reseller here that has a metric ton of sega games in a wire bin

I respect it as well, as much as I would like to be a collector (and I do have a ok collection of vintage computers) I dont have all that much room at the moment, so everything is loaded onto an xbox (original, cant say one anymore) I had a love hate relationship with emulators, but what settled that argument in my mind was having one hooked up to a CRT tv and over the years cobbling up USB mods to various original controllers, its pretty close, not perfect, but pretty close

it might be a pal only demo, I dunno, I have only ran it via emu

using a pal or ntsc model?

yep, a lot of TV's in the early 1990's didn't have a remote or stereo as well

yes the 8 bit machines could do nowhere near the graphic quality of the 16 bit GS

I only had a model 1 High Def system, so

I have a radio shack joystick that is pc/apple II compatible, kind of junky though this isnt my picture, but I have the same one as the beige n brown joystick in the middle http://s3.amazonaws....397462b93f1.jpg oh and its a 9 pin model, so if you dont have a //e enhanced or //e plat, you will need to mod the cord, but if you start doing all that, its pretty easy to convert any analog joystick to work with an apple

Released just a couple days ago at Evoke 2013 ... genesis does ... http://www.pouet.net/prod.php?which=61724

heh, I dont shop for modern games much, all I have is a Wii, but it actually caught me off guard at walmart looking for a wii game, I saw the U and thought to myself, "I forgot that even existed" and kept walking

ghouls n ghosts, contra hard corp, any of the Shinobi's, any of the thunder forces, ghost busters, strider, and freakin road rash just to start

well I am getting good clean voltage to everywhere it needs to be with minimal ripple, input is a snotty bench supply edit: I will admit the power switch is a bit junky, but in its most extreme its ok

So I got a dead 2600 JR from Ataribrian to tinker with ... cause I have fun fixing dead machines, and have never done a 2600 before. He had said that the unit only produces a black screen. Once I cracked the unit open I removed the giant electrolytic cap and tested it with a meter, the 2200uf cap measured out to 2830 something which is fine. I also replaced the 7805 regulator since the stock unit apparently was never screwed down to the PCB plane and was seriously discolored from heat abuse, but otherwise worked fine. I used hot air and solder paste to bond the new 7805 to the ground plane and its running much better. I did a quick n dirty composite mod and did a little cut to the trace feeding video to the RF modulator (thinking maybe something there might have blown). On the oscilloscope I get a nice color burst signal and chroma signal, though I do not see any sync signal ... and the picture on my TV tuner seems to confirm this as sometime it rolls, or flickers (of course no lama signal since the screen is black). Also poking around I notice that I get a nice clean 3.57Mhz signal from the oscillator section of the board which goes into the TIA, the clock out of the TIA though is a funky rounded over saw tooth wave, that does not meet the voltage / timing requirements of the 6507 nor the 6532, which are both in an idol state. For anyone that knows me I hate shotgunning chips that are getting more and more rare, but it does seem in my inexperienced with this system mind, that I might have a faulty TIA chip, can anyone confirm?

bought a (known) dead 2600JR from him to tinker on, fast shipping, good communication, A+ all the way

on a normal apple its composite, should be the same

basic is baked in but dos requires a disk, typically programs are self booters so if you have software you have dos

I think it would be more prudent to get the correct cable and see if you blew anything before you go shotgunning this using up as much hardware as possible ... I am not a 64 expert but the outputs on the back of the TV is going to put out at most 1v and the inputs are not going to measure anything, making it interesting that one could blow anything with a high impedance analog input inside the device

I used to run mine into a PC running at 1280x1024 upscaled and it was pretty decent for composite, but yea its china, roll the dice and good luck sucker heh

no thats fine, I might take you up on that if postage is not a beast pm sent

any missing chips on the jr?

for football owners who may be outpriced on this impressive, but yes expensive mod may I suggest eBay Auction -- Item Number: 171095133108 I had one of these back in the day with my football gba, you replace the entire back plate of the gba and when you wanted tv out you latched on a backpack, making a chunky machine, but no worse than an xbox controller its composite only but on my unit it did a pretty darn good job, after some time the back pack did get a little loose so you had to watch the rage quits

yea, LCD, SRAM + tiny battery how much do you think postage would be via USPS?

so rubbing it the first time with polish made it work for a moment, but no luck since ... check for bad / cold / cracked solder joints, maybe you hit a sore point out of sheer luck to make it fire up
