I second that, thanks for sharing all these @Fizzbinn , @NJRoadfan & @cheesestraws

Macintosh IIvx The image is from an auction for the IIvx with CD-ROM, the pdf is a reproduction I made is for one without CD-ROM.

Thank you for sharing this :)

I also needed to answer this question, a scrap 80 conductor IDE cable ought to work. I could not find the LCD side connector, the header is marked "CW Pat. 4669801" Yamaichi Electronics NFP-26A Logic Board Connector NFS-26A-0111 wire mount connector Cable: Half Pitch Ribbon Cable 0.025"...

You can use the photo as well if it helps, it is public domain.

Recapped the PSU, it was not the Sony so here are the capacitors: Macintosh Portable Adapter M5136 ( SMP-10BB ) 7.5V, 1.5A Limiting to 1.5A NTC1 400v 56uF 22x25mm, 12mm Snap In 105c C4 10uF 50v 105c C303 100uf 25v 85c C301, C302 1000uF 16v 105c C505 4.7uF 50v 105c

It chimes, then death chimes. Sad Mac error code 01000400 0007FFF6 Following http://myoldmac.net/FAQ/SADerror-portable.htm to decode results in ROM test failed, divide by zero. At a guess, there are traces hiding under chips that are bad, or logic chips were zapped by someone trying to power...

Where are you located, that may help with how to sell

Recapping a portable, it happened to have the backlight upgrade installed. I did a thing to it, but hopefully this may help others. My dwell time was too long, I hadn't added enough new solder, so it suffered some delamination and a lifted pad. I need to know a reasonable value for L1, I'm not...

@dankcomputing , have you been running at 33mhz with non-LC 040, how has it behaved? I want to do this to my Centris 610 as well

I've added an initial draft entry to caps.wiki https://caps.wiki/wiki/TDK_MSE103

Im working on my centris 610, just got to the TDK power supply, I havent edited the pictures or measured the caps to add to caps.wiki yet; regardless here is the list of values and locations from mine: Q610, Q660 TDK MSE103 Apple 614-0022 Fan Controller PCB C201, C202 33uF 35v PCB Daughter...

Amazing work, thank you for your this! several of those daughter cards caused the population of my currently-beyond-repair heap to grow; do you have any completed boards available? What would be the minimum circuit needed to test the cards without a power supply? Does the spacing match any...

oh a second resurrection .. I also have a battery bombed Q700, the crystal oscillator at Y6 lost a leg to rust; I do not know if I will be successful grinding away the housing to solder on a jumper. It took a while to find its specs so: Y6 & Y5 Crystal Oscillator, clock xtal, 32.768Khz, smd...

wonderful, much better google-fu than I. Much appreciated, one step closer to installing A/UX... And I'm guessing bitsavers as the source; to help increase hits https://bitsavers.computerhistory.org/pdf/sony/cdrom/CDU541-25_AppleCD_150/
