After cleaning pin 1 just a bit, a chunk fell off: poor diode's probably not receiving enough juice, maybe?

Hmm, guess I'm in the market for a new optocoupler maybe. but I'll want to test it out first.

I'm going back to inspecting the analog board. Here are the edge connectors on the AB side, the large ones seem fine: The small ones are looking like this mostly (80% of them): The end near towards the transformers are a little bent towards the bottom and one pin is slightly crusty: Is...

Do you have any more updates on this @jcm-1 ? I'm thinking my problems with my CCII might be board edge connector related. Here's my recent thread about it: https://tinkerdifferent.com/threads/mu0ns-color-classic-thread.1252/post-9567

State A: the state as I received the machine initially (plugged: logic, back of the case, hard disk, floppy) Flick the power switch on, press soft power on the keyboard - get a brief led flash, then nothing. State B: worked for a few days, but required plugged in prep HOURS (plugged: logic...

I put the diode back, replaced these notorious caps: and put it back together (no, I didn't forget the ground cable by the screen) and I get back the same behavior as before this recap push: -Flick the switch on, hear a brief, soft, high pitch sound -Soft power button does nothing -Back to...

I've taken one out: Diode mode: forward: 727 - increasing towards 1000 reverse: 1 Resistance mode: forward: 648kOhm reverse: inf

Hmm, can't find the exact type of diode here: https://colourclassicfaq.com/tech/ccparts.html GONNA DO IT and test out of circuit

Current status: -Recapped logic board -Does not boot anymore (black screen, no chime, no screen power, I didn't wait a full 24h period plugged in though) -Recapping analog board (specific caps at first as per https://recapamac.com.au/wp-content/uploads/2019/08/mac_cc_analog_recap.jpg) in...

could you place the speaker farther to reduce the interference? or is it something that happens as a noise in the voltage picked up by it?

I came across this demo I had forgotten in some nondescript collection of graphics applications folders I had laying around. Some people in the Boston Computer Society took it upon themselves to recreate (in 1986) the 'boing!' demo from the Amiga which features a fake 3d bouncing ball animation...

My Plus also has that sound.

So........ buyee refunded both the machine ($135 CAD) and the shipping ($223) - the part that was paid by paypal appeared immediately, still waiting on the normal delay for the part that was done with my bank account. Wow. Ok.

Still waiting on a 1-2 week long decision for a refund claim, but I thought I'd check out if my pieces fit the cracks. I'm missing an important one. I'm considering acetone (I'll just use a nail polish remover) to try to bond those pieces together. I'd love a rundown on if it's a good/bad idea...

I'm already using a pi3a for a mt-32 pi, and a pi3b repurposed from a retropie machine connected to my tv to a usb4vc device that can take modern controllers and ship it to a vintage PC's ps2 ports, gameport and serial mouse port. This device will also have another extension board for earliest...

I got the standard plan (which includes insured shipping) and paid for the repackaging. Who knows if I'll get anything for it or if I'll fall in a crack. I don't have any ethernet capabilities for any of my old school macs. My collection leans on an earlier era than most people in these forums...

Current status: -pictures of the received box + clear shots of the damage that can be x-referenced to the original auction's shots, sent and claim filed to buyee -caps ordered for logic and analog boards -stored away and not powered again until this is done

Someone told me on twitter that it's probably a LC550 board with enough vram to enable thousands of colors (which I did try out successfully)..

It's a color classic II after all, with a logic board swap in its past! It was hinted at without strong confirmation in the yahoo Auctions description, but the translation was a mess. Here it is (highlights of the parts I find the most funny by me):

BlueSCSI steps: Using the 40 MB 7.5.3 hda that can be gotten from Mac Garden, I brought these things from the Apple Recovery CD (copied via an emulator) to another bigger hda used for shuttling stuff: -system 7.1 install imgs -color classic system 7.1 install imgs -system update 3.0 (meant for...
