This is Common on Color Classics it’s the internal speaker causing this issue. Happens on my color classic ii as well.

Bad ROM I actually have a spare set I made.

They usually vacuum seal foam around their stuff, I believe they use DHL.

No buyee packages very, and I mean very well.

For me yes but this was on a 512k the pinouts seem to be the same so I don’t see why it wouldn’t,

Used it on that and had absolutely no issues.

I used one of these on a 512k board looks to be same pinout.

So I have a iivi and it’s been recapped, I know the power supply is perfect and there’s no corrosion. However when it boots the fan spins the, led comes on, but after that nothing else just stays on with the fan running, any ideas?

So like shutdown and restart in the control panel freezes and locks up the system, this is so bizarre.

Old caps leaked resoldered all ram chips it boots fine but lags like I said above still

Thank you it works but still won’t boot up without extra ram simm, and by boot up I mean chimes no problem but no video unless the ram (not vram) simm is in. Also when it boots there are no problems I only run into issues when I choose shut down or restart as the computer just freezes, this is...

Oh I see so all on board RAM has to match, I removed this added chip and it boots just fine with 7 of the 8 RAM chips so that's cool, obviously some applications are now drastically slower such as startup and restart/power off.

Hello everyone I have an LC475 motherboard I purchased from Europe the Board has the distinct EURO after the serial number on the board. I bring this up because I am in the US and am having some doubts about things. For starters I have installed a working known good CPU, I have cleaned the...

I don’t mind, no worries I am looking for units outside of the USA, so if you have an extra let me know.

Probably can, it’s just you have to pry plastic and it gets a bit scary there but I’ll give it a shot tonight.

Would be wonderful, thank you.

Actually don't need an analog board I think.

Either the chip will be an MX1000QC-12 or a AM27C512 you will need to dissassemble the rom pack (just unclips or pops apart) from here you need a 32 pin PLCC adapter and a tl866 (link here). Once the ROM pack is open pop out that chip that is socketed it will be the ROM.
