    Testing a Color Classic Analogue Board with no LB

    I'm going to answer my own post for future reference. Yes, the AB will power up with no LB. Mine did not because it was bad. If the "shutdown enable" pin is grounded, then it will NOT power up but with no modifications the AB will power up as soon as mains is fed to the board. I haven't tested...

    Broken inductance analogue board Mac Plus

    Thank you! Next one is still in the making, the caps on the Color Classic AB decided to have a leak so I'm still mopping! :) So many unknowns, I have no idea whether the LB or even the CRT works on that machine.

    Broken inductance analogue board Mac Plus

    As promised, here is the video repair! Comments are very welcome! I mentioned Tinkerdifferent in the video and linked these pages in the description. Thanks again for your help!

    Testing a Color Classic Analogue Board with no LB

    Hi all, I am working on a CC in need of attention. Unfortunately it's been stored improperly. The good news is that the LB is not too bad. Usual leaky caps which haven't caused too much damage. The battery is intact. Now, there is capacitor leakage on the AB so I'm planning to fix that first...

    Broken inductance analogue board Mac Plus

    I hadn't cleaned that yet so good point. The Tube is now spick and span and yes, I've added some dielectric grease under the suction cup indeed - It seals it and makes it glide on the glass which facilitates removal if needed. What I saw though (only once) didn't feel like HV glitch - the...

    Broken inductance analogue board Mac Plus

    Thank you! So far so good, I really don't see issues with the CRT. I caught it jumping once, I since cleaned the pots on the analogue board. Today I've tinkered with the Yoke and the magnets and all the adjustments and I'm happy with it! Thanks for the idea about Snooper 2.0 - I was wondering...

    Broken inductance analogue board Mac Plus

    Update. I measured the inductance and it read 0.3Ohm, 0.01mH. With or without the broken part (which I could slide out easily). I glued the two parts with epoxy, left it overnight in a clamp. The following morning I tested the inductor again and it now reads as a resistor, 0.24 Ohm. Yes, the...

    Macintosh 128k/512k/Plus 240V Analog Board Recap List

    Hello Andy, Thank you so much for this list! I am recapping a Plus and I think there is a typo in the list. C11 is listed as 10uF 16V but it should be 10uf 160V - the Mouser link also points to a 160V one. I hope this helps and thanks again!

    Broken inductance analogue board Mac Plus

    Thanks again, I understand. I will check that there is no further damage and try to measure the inductance for future reference. Thanks for looking into the schematics for me, it's nice to know what that is for, so I can check if it has any effect. I'll make a repair video of this Plus, I'll...

    Broken inductance analogue board Mac Plus

    Thank you Callan, So you're saying that what is outside of the winding does not count for the intended inductance? I can try to measure it - good idea - but I don't have a reference value to compare it with. Indeed I was thinking of gluing the two pieces and then add some hot glue to the...

    Broken inductance analogue board Mac Plus

    Hi all, I'm restoring a Mac plus and while inspecting the analogue board I found the below inductance with a broken core. I'll test this unit once I've removed the RIFA and replaced some leaky caps, I am told the picture was a bit wobbly? Question: do you think it definitely needs a...

    Mystery Apple // card

    could be interesting! I need to ask the owner of the card as that is not mine. I have no idea what software it belongs to though. Do you think we would be able to find out by looking into the ROMs?

    most affordable floppy alternative for Apple //

    Thanks Eric, I'm afraid I'm not following then. I am aware of the ROM requirements for the //c but the //c has a 19pin port at the back. The //e does not. So I guess I would need a floppy controller card which is compatible. I checked the link you mentioned (Thanks) but I did not find mentions...

    most affordable floppy alternative for Apple //

    Thank you both! I totally agree with the authentic feeling of a floppy - I guess it's just a matter of practicality as there is limited staff around. Exploring options though and it would be great to also have a floppy installed for the familiar "slicing" sound :) I believe this //e comes...

    most affordable floppy alternative for Apple //

    Hi all, I am helping a local museum of computing to display some Apple machines. Those would be turned on and available for the visitors to use. Floppies are probably unreliable/impractical to use. A Floppy EMU would work but it would be expensive. Is there any other option for a fixed...

    Mystery Apple // card

    interesting. Too bad the link on applefritter is not available anymore. Will a diagnostic software tell me more about that card?

    Apple IIe disk drive lights and spins continuously

    My //e gave me headaches when I restored it. The drives would work intermittently. When working, they were fine. The following day they wouldn't. Only after a while I realised that the crimped bit, where the connector is attached to the flat cable, had oxidised and moving the drives/cables...

    Mystery Apple // card

    Hello all, I've opened an Apple //e today and found this mystery card in it. Any ideas of what it could be? I plugged it in, nothing weird happened. is there a way to query what card that is? Thanks!

    Apple //c repair video

    Hi all, I've now managed to fix the final fault on that drive! I was not expecting that to be honest. I might check my //e drives as well. As usual, comments and feedback is very welcome!

    Apple //c repair video

    Hi all, Some time ago I got an apple //c from a friend for my own pile of old nostalgic boxes! I was told it had an issue with the floppy but it turned out to be a much more interesting repair, with the floppy actually dying on me after it was fixed! As usual I made a video out of it. I hope...
