Apologies for the necro-posting, but here's a thought - what if the av mod was kept outside of the case in order to move the signals away from the power supply? I mean, it's a little clumsy, but if it could result in a clean, stable image on the Intelly II, I'd gladly take it. The RF on my Intelly II is hot trash.

Yep, that little fuse was it! Now just to find a suitable replacement and I'll be back in business. Still frustrating, but I'm glad to know nothing else was fried (and that the fuse did its job!)

I know about the thermal fuse behind the voltage regulator (what is that, a 7805?), but uh... now that I'm looking at it again, looks like there's a baby one by the player 1 controller port, and there's no continuity across it. Suppose that might be my issue?

I JUST finished recapping the power board on my Intellivision II. I went to tweak the RF modulator to see if I could get a better picture, slipped up with my screwdriver, and a spark flew. And that was that. I *think* the short occurred between the positive end of the large capacitor and the RF can. What's the most likely culprit here? All test points show nothing (except the AC voltage, which is dandy).

Perfect, thank you!

I live IN North Tonawanda! On Oliver St! Thanks for the help!

Anybody have the controller matrix handy for the Intellivision, as well as how that matrix is wired to the Intellivision II's controller port? There's a topic from ten years ago that had it, but the image links are now broken. Thanks all!

Dear God, I wrote that on this forum twenty years ago. I was 14 years old.

Got a new one up - this one about early 70's arcade games, the sorry state of preservation they're in, and what can be done about it. https://memorymachinepod.com/2021/05/03/the-memory-machine-57-the-70s-video-arcade-game-preservation-society/

New podcast all about the Atari 7800 and heaping praise upon it, featuring guests from the Pie Factory Podcast, @Inky and @Dauber! The Memory Machine #53 – The Atari 7800: An Appreciation – The Memory Machine Podcast

Has anybody checked out this project or tried to build it? It's a diy clone of the Vic-20 using all new parts, excepting the VIC chip. I'm feeling quite tempted to build it for myself... https://bitbucket.org/danwerner21/vic2020/src/master/

It seeeeems like it would be fine? I can't think of anything on the board that runs directly from the 9v input.

Just put up the newest one, this time with arcade historian Ethan Johnson about the era of penny arcades (pre-pinball, even!) The Memory Machine #52 – The Era of the Penny Arcade w/ Ethan Johnson – The Memory Machine Podcast

After much hemming and hawing, and fumbling about trying to start my own website and RSS feed, I've finally relaunched my podcast after a hiatus! The first one back features historian and Atari Age-er Kevin Bunch (ubersaurus in the forums), talking about his YouTube series Atari Archive, as well as ventures into the worlds of the RCA Studio II and the Bally Astrocade. Enjoy! The Memory Machine #51 – A Conversation With Kevin Bunch (Atari Archive) – The Memory Machine Podcast

Must have gone awry with Brexit. I remember stuff being shipped to America from the UK was peanuts about 5 years ago.

Is it just now acting up with the cassette? Could be an issue with the SALT circuitry...

I recently recapped my CoCo 2. Makes me feel a lot better about its longevity. Now I'm just waiting for a composite board to come back in stock so I can finally chuck the god awful RF modulator in the trash!

Wonder what could be causing that? Failing caps maybe?

Glad it's not just me who thinks the CoCos have garbage RF output. I can't wait until Ed Snider makes some more CoCo 2 composite boards so I can put one in mine!

I got an unexpected bonus on my paycheck, so I went ahead and pulled the trigger on the Harlequin 128k from Byte Delight. Now I just gotta get a system ROM, a case, a keyboard membrane, rubber mat and faceplate. Basically, this is now the retro computer equivalent of the Johnny Cash song "One Piece At a Time".

Aaaaaand I was WAY outbid on the Speccy I was eyeing. After reading some of the responses and weighing the notion of getting a fixed upper when I will have to order most, if not all repair parts from overseas, I think I'm gonna go the Harelquin 128k route. It'll be a great quarantine project to build a Spectrum from the ground up!

Well, I finally got the hand wired keypad working! I decided to just do it over given that desoldering and resoldering all those diodes would have been way more of a pain than just starting from scratch. Now comes the question of: what should I house it in?

I currently have a low bid winning on a Spectrum, but if I'm outbid on it (and I'm likely to), I'll probably just go the Harlequin route. I like soldering stuff anyways ?‍♂️

That's been my trouble so far - finding someone who will ship to the states and not have the shipping cost be astronomical. This seems to be an issue unique to the UK so far, with shipping costs from the rest of the EU often being about 30 - 40% less than what the UK is offering. Damn it, I just want a bog standard Speccy!

This is another reason I'm interested in picking up a Spectrum. I love how easy it is to get under the hood!
