I wasn't sure. I checked out some photos online and it seemed like a roach. I'm not sure how a moth would have managed to crawl between the bottom of the motherboard and the bottom shield.
@flashjazzcat I was a licensed pest control operator and killed thousands of roaches. Trust me when I tell you it's not a roach. The moth was attracted to something, maybe heat, electronic pulses, or the previous owner spilled something on the keyboard. I have an Atari 400, 800, 130 XE, 520ST, Mega ST. All put away in mint condition. Love them and enjoyed your upgrades.
Happy Holidays FJC! Awesome production, mods and info as usual. My first Sega Saturn was a Roach Motel. They checked in and never checked out. Purchased from a retro game store years ago, I was green at the time and didn’t know what I was in for 🤢🤮. LSS it’s my favorite Model 2 Saturn till this day. Fully restored with a M.O.D.E ODE installed. Luckily they were already DOA but man that was some nasty work. Legs and body parts between chips and caps. Hahaha I was grossed TF out.
I had some micro hdmi boards made for the Sophia 2 for my laptop build because i needed the smallest cable and connector as possible to feed into the display. The micro hdmi is small enough to push the jack through the hole on the back of the xe where the rf jack goes. I’m pretty sure I have some extras leftover if you want one.
Ok I found them I have one bare board left. Are you ok with SMD soldering the micro HDMI connector into the board? I used solder paste and hot air gun. Also the ribbon cable connector but that’s through hole so that’s easy. I can send the micro hdmi connector the board and the red ribbon cable connector (I forget what it’s called).
@@sideburn They're probably endemic at this point. Not that it seems to affect functionality, but it's rather alarming to see a bodge like this on an £80 board which is after all a fifteen year old design.
Shoot me an email (it’s on my TH-cam about page) and I’ll send you some links to some images so you can see it I also have the boards on oshpark. I can’t put them in here or my comments will delete
What about the audio that comes from the SIO port (cassette playback), as well as the internal BUZZER? On the old 800/400's the internal buzzer was a built-in speaker. On XL/XE it's been moved to the analog video out (and TV out). Will the new pokey replacement incorporate those some how? 33:00 Oh would you look at that! Oh that's ground.
PokeyMAX has a GTIA audio-in connection, so that takes care of the console speaker. SIO audio-in I'm not so sure about, although it's comparatively rarely used these days.
@@flashjazzcat yeah mostly for audio cassette playback. Some games had a mix of both Data and Audio playback on the same cassette so you could hear some sort of narration or music after a title screen appeared before the game fully loaded. Which actually made the loading of the game take longer since you can't mix data and normal audio together (i assume)
@@fragalot I've just checked the schematic and indeed there is no connection between SIO audio in and POKEY, so unless the device happens to pick this signal off, the audio won't be present on the stereo mix. I assume music would be on the second (stereo) audio channel on the tape, which would allow simultaneous data transfer and music playback, but that's just a guess and I don't know for sure.
@@flashjazzcat yeah it's been 30+ years since i ever used a cassette drive, and i started off using floppies with my 800XL. I did have a 410 and some random tapes but rarely used it.
For the angled headers, it's not really a matter of orienting them to get the plastic in the right place, there are actually two types of those headers, and surprisingly the desired one for an application like this (the UAV) is much more difficult to get in small electronic shops, for reason unknown to me. Bottom line - at some point I ran out of them, while I had piles of the other kind :)
That's correct. I'm not reorienting the angled header, since this would result in preposterously short pin length on the connector side. One type has the plastic frame resting on the PCB, the other has it just beyond the right-angled shoulder (and this would obscure the silkscreen on the UAV).
It looked like there were some patch wires already on the board when you first opened it. I'm guessing those were from the factory, but if you mentioned them, I missed it. Were those standard fixes seen on all 130XE boards of this generation from the factory? (In any case, another comment to help the algorithms.)
Yes, that's a factory stability patch and you can see at 32:32 that I moved them to the underside of the board in order to socket 74LS08. I believe the later revision boards (4 DRAM 130XE) eventually dispensed with the patch wires. Discussion at 35:17.
Not a roach. A moth...

@@jameshorn7830 Thanks! I unreservedly defer to your expertise on the matter, then. Thanks again for the kind feedback.
Roach gave me a flashback. A family of them in a 7800 cart, alive!
Oh yikes.

Thanks! Amazing what a good clean can accomplish. :)

Thank you! I'd love to try one, give it a test and demonstrate it on video. :)
I’ll check my stock. I just watched this video and noticed i also have the bodged U1MB with the alliance ram

Donald Trump impressions? We have been spoiled.
that was hilarious 😀
Kafkaesque 😂
That machine is buggy 😝

Interesting. Someone must have had a very close relationship with their Atari.
