  1. Solved my problem here I think, however potentially still something lurking somewhere, interested in thoughts. Here's what I had originally did and changed: For the Pokeymax installation into the 800XL I was referring to this video from FJC (which I realise refers to 600XL, however unsure differences matter here): At 24.53 you can see a convenient ground is used as opposed to the ground from Pokeymax. One less wired going across the board, and I did the same after checking continuity to ground from what I believe was same resistor on my board (case closed now, too lazy to double-check). Recalling this, and on a hunch, I desoldered it from the audio jack and took a wire back to the ground on the Pokeymax itself. Seems this now runs fine, with everything wired as shown in my original post. So that shortcut somehow caused my issue (though would not be surprised if in conjunction with something else that is still wrong somewhere). Thoughts? (and I'll add an @flashjazzcat here, though don't get me wrong, I'd be lost without some of your guides, so just for interests sake here and whether any thoughts re that ground wiring. In isolation it indeed worked just fine). Have a good day all. Tim
  2. This one's going to be tricky to explain, but interested to know if makes sense to anyone. I'm sure something unique to my setup here. I have working 800xl and 600xl here, and recently working on the 600XL, added 64k+U1MB + enabled Svideo following guide from FLC successfully. Not completely relavant to this, as issue occurs without the 600xl hooked up, however after problems testing with cable i made up myself, that I didn't trust, I bought a HQ audio video cable from Retrolemon in UK, and used for SVID connection, via a SVID/composite to scart adapter into a Sony Bravia TV. Very nice video. The audio i had hooked up from the cable into a Soundlab mixer I use, then on to my amp. All worked well. When I returned to using my 800XL, something odd happened. I first had plugged in a spare USB PSU I had (wanting to see if it ran it ok, and could have both atari's cabled up in parallel. The PSU I was using with the 600xl I had previously used for the 800xl and was borrowing it. Anyway, upon turning it on I had a audio blipping and screen also flashing. Didn't sound good, turned straight off. Returned to proper PSU. 800xl won't power on any more. My first thought, I'd fried something in it by potentially using bad PSU. Later, simplifiying by plugging in only essentials - known good PSU and DVI from Sophia into a monitor, it boots fine. Cabled back way things were before (including Pokeymax to Amp connection). Won't boot again - black screen. Skip to the end...... I find that when both the svid and audio cables from the HQ audio video cable setup for my 600XL (which incidentally are not currently connected to anything on the Atari 6 pin DIN side) are hooked up to the TV and the mixer, the Atari 800XL with Pokeymax audio connected to the same mixed will not boot. Furthermore: If I remove the HQ cable audio connection(s) to the mixer and boot the atari 800xl; if i connect the HQ audio cable to the mixer after boot, the 800xl cuts out. If I remove the SVID conenction from the SCART adapter taking it into the TV, but HQ audio cables left connected to the mixer's other channel, the 800xl boots fine, no issues. What on earth is going on here. Something shorting / grounding incorrectly somewhere. I'm stumped, but something is really off here. My setup if this helps - interested if anyone understands this!
  3. Hi all, I'm slightly confused as to why I cannot get output from Sophia 2 to to a Sonia Bravia KDLV4000 TV I am using. I have tried all resolutions using the sconf tool, and given the following: - On two small monitors I own, I get output using 1280 x 960. One has HDMI input, so using DVI to HDMI cable works fine. Other DVI to DVI, also good. - The Sony TV accepts input from a Windows 10 PC using two different DVI to HDMI cables I've tested at same resolution - 1280 x 960. - Same DVI to HDMI cables when used with Atari (800xl) fail to get a picture. Any thoughts anyone? Can only get output to that TV via Scart cable carrying composite at moment, so not so good. Video on the small monitors is very very good, so would love to use this larger screen also as I intended. Thanks, Tim
  4. If anyone's interested, I documented my recent experience sorting out an Atari 2600 Jr I acquired. Commentary and photos in attached PDF. Just noticed the PDF instructions for the mod didn't embed properly, so will post that also (hope originator doesn't mind - free advertising after all). All comments welcome, I'm an amateur at best, but happy with result here. TJ76 ATARI JR VidMod SwitchFix.pdf notice_installation_AV_MOD_atari_2600_JR_PAL_EN.pdf
  5. Would love to be involved. Just repaired a 2600Jr, and have a light sixer to sort video on soon also. I have a Uno cart in post to me, so should be able to load roms from that.
  6. Thanks for these replies, which I've read with great interest and trepidation. Had a bit of luck now though to be honest, as thinking a RIOT replacement could have been on the cards, or at least ruled something out by swapping it, I eased out that chip, and also gave the board some careful cleaning. Upon returning the RIOT and powering up, I now have working joystick ports! Unless this is intermittent and requires further investigation later, I can move on to improving video and getting sound back. Thanks and goodnight. TJ
  7. Found my meter finally and checked this out. Continuity to voltage regulator seems ok, and seems to have consistent continuity to pins on the RIOT between both ports. Going to take a punt and replace RIOT, as can source locally within a few days relatively cheaply. Fingers crossed.
  8. Thanks both, always good to have right kind of pointers to kick me off. Would love to have this working normally again, and then look at getting some more modern video out of it as next step. Will try and find some time later today / tonight if the family let me Once i find my multimeter which i seem to have mislaid as didn't locate it last night. Have a good weekend. TJ
  9. Good evening, Wondered if anyone could advise here. Acquired a Woody light-sixer and looking to restore. It's a PAL unit and video is ok over RF modulator, however hiss instead of sound. No experience working on these, however have installed mods into an 800XL including installing new sockets, so have reasonable soldering skills. Getting no joystick input at all. Looking at main board, this doesn't look right to me, but not sure how it's meant to be. Looks like one damaged capacitor at C232, a disconnected one at C236, and looking at rear, I see solder bridges in that area that don't look right compared to example images I've seen. Any thoughts on how i fix anyone, e.g. what components i need to replace, and what may need de-soldering? Not sure what I'm doing here - a little project and learning as I go along, so be kind! Issue looks to be with Left controller. Last pick is rear of right which doesn't seem to have same points bridged.
  10. Ok, sorry guys, clearly just being OVERLY cautious here. with a little manipulation and not too much force, I found this does come out. Guess something not moved for 42 years can be stubborn! And result, as expected - a fully socketed board in VGC. This Woody cost me £37 delivered, so very pleased!
  11. Looked at this old post mentioning only 2 screws : So strange mine is so solid after removing those. glued perhaps?
  12. Good afternoon / morning all. Recently lucky enough to acquire a 2600 woody at a reasonable price. I believe it's 2nd edition, with 1978 on the main board. Was listed for sale as untested due to no PSU, and on a quick test I immediately got screen output testing with frogger cartridge, so very happy. Didn't try to play it before taking a look inside, and now note at least one joystick port may need attention, but that's for later. I'm interested to get the main board out to look at as understand this should be socketed allowing a relatively easy mod for composite output to avoid using the analogue via modulator. Watching this video, at 7.26 it looks so easy to remove, however mins seems stuck. There is some flex on right hand side of board on image I'm about to post, however on left near underside of cartridge slot, it seems solid, as if some screws i cannot get at holding it firm. Clearly don't want to force anything and damage it. Anyone have any advice for me on how to get this out? Thanks! TJ
  13. My main setup is an Atari 800XL with Ultimate 1MB, Sophia DVI, Side 3 running latest 0.19 firmware and an Sdrive Max on the side. Prior to a few months ago this was stored in a loft for years, and back in the 80s and early 90s, we only had a 1010 tape drive, therefore my knowledge on installing these upgrades, and using things like Spartados and 'disks' in general with an Atari are only a few months old - playing catchup here. After using Side3 in rather basic fashion for a while accessing SDCard with single FAT32 partition to load ATRs, XEXs and ROMs from the loader, I've, after a couple of mistakes, reconfigured a card via fdisk under SDX to have APT and Fat32 on same drive, and have been able to copy files between SDMax card and virtual drives on the card in the Side3 under Spartados launched from the U1MB. Along with nostalgia of playing games from my youth, I want to continue doing more useful things with the Atari, and had started teaching my son programming in Atari Basic, and soon after discovered Turbo basic which was helpful to speedup some random number generation we were doing in our program. I can boot turbo basic from the ATR I have via the SDMAX, and access .bas files stored on a drive mounted on the Side3. Now the potentially silly question where I don't know what I'm doing - Can I transfer the Turbo basic .atr to one of the Side3 PBI hard drives to boot it from there. It's a Dos 2.0 .atr , and if i copy the files across, and attempt to boot from it by selecting in U1MB as boot device (d3) , I have BOOT ERROR displayed repeatedly on screen. I wondered if for compatibility I needed drive to be setup as DOS 2.0, however in Format I seem to be unable to change mode of the drive. Apologies if obvious / covered elsewhere, but lacking in knowledge here - best way to have selectable Drive to Boot into Turbo basic. Thanks all, good evening and have enjoyable weekends. TJ
  14. Thought I'd take a look, but says invite invalid. Perhaps something I'm doing wrong as have not used Discord before.
  15. I love this community. For what I saw as a trivial issue with a single XEX file, the level of attention and desire to find out what's going on and swiftly fix just shows the heart that goes into these products. Sadly lost I feel with modern corporate software companies. Works great. Still get wiped out by Jammy Jim in the final, but don't expect anyone can help me there
