  1. Great video, I'm going to see if I can follow the same procedure for the SCSI selector on my external CD ROM drive - put a 300i in a Panasonic SCSI enclosure (Panasonic drive was dead) - would be nice to be able to select the ID's.
  2. Can you show a picture of that? I hope you don't have to go down the on board ram path!
  3. If you haven't tried a known good set of ram I'd do that, my se/30 showed this with bad ram. Seems like you've tested almost everything else!
  4. Not quite sure yet heading out on vacation tomorrow so will be doing some reading thinking on it. Will let you know what I choose.
  5. I've solved the Analog board issue! After reading both links above I looked at my board again. There was a lot more electrolytes on the bottom side than I thought - it's not the normal "shiny grime" - more of a slight discoloration - and there was so much of it i honestly thought it was just the normal color of the PCB! I scrubbed a lot with 99% IPA between each contact that i thought could be a bridge and used a tooth pick to clean crust off. Focusing on LL1/LL2 and the other major components. I did note there is quite a bit of yellowing of traces that probably got too hot at one
  6. 12% hair product (thought it was 40%, but the label was misleading!) and oxi - the "classic" method I suppose. Still a bit of reading to do. I've done the sun only with good success, but this one is quite yellowed.
  7. Good call, have seen this done before but I haven't tried it. Found a thread on a similar problem from 2019 though it never wraps up - just goes off topic on WD-40 http://www.vcfed.org/forum/showthread.php?68426-Mac-Classic-Analog-Board-Low-Voltage-Problems Has a few things to try though. Edit: Reading through chapter 9 here - a ton of things to try http://www.maccaps.com/MacCaps/Repair_books_files/Mac Classic %26 SE Repair and Upgrade Secrets.pdf
  8. Only 7.1? I just extracted a fresh blank, booted up in my SE/30 7.5.3 and "injected" the blank - showed up as "Untitled" - My SE/30 is stock with a Ethernet card. Sorry not much more help other then "it works for me"
  9. Soap, water, magic eraser and it's now "clean" - removing the stickers you can see the original color. The front actuallyd came out quite nicely and not yellowed much. Took a few minor spots of rust off and cleaned the inside too. If anyone has ideas on my "needs warming up" recapped PSU I'm all ears. Will be trying some retro bright on the back cover next week as it's so discolored.
  10. Wow! Hope there's one or two versions of things not uploaded to the garden yet. I recently went through about 70 800k disks and 25% of them were unreadable - be interested in your % bad after you've gone threw them.
  11. Analog board recapped, always triple check, had one marked down wrong (luckily noticed before we started) Still the same issue of needing to be "warm" to boot & for the waves to go away. Anyone have suggestions on what component might need to be "warmed" up to be replaced? Thanks!
  12. Caps came yesterday - did the logic board today and tested it in my working Classic II - wish more Macs came with bootable rom. The recap went well, always one joint I dont like and have to retouch. First boot it gave me a checkerd screen, then rebooted a few times in a row, then was fine. Subsequent reboots had no issue. Analog board will be tonight or tomorrow.
  13. I took a known good PSU from an SE and put the recapped analog board on that, tested the voltages, all was good and booted right up (well brightness was all the way down, so that took a few minutes of debugging ) Question still remains, what should I do with this Astec PSU.
  14. Hi! I'm trying salvage what I can from a maxwell bomb SE/30 and recapped it's analog board so far and was going to test it. Before I test the analog board I wanted to make sure the power from the PSU was correct. It's an Astec PSU. I took some readings and they were not "stable" mostly going up and up as it got warmer and "odd" numbers (not 12,5,etc). If someone has the pin voltages at the PSU output connector I'd appreciate it! My google searches came up empty. Thanks, Quick edit - I think this diagram R, Y, O, G (colors) is what I'm looking for
  15. I just installed/did the same thing today on my color classic and got it working. Fresh copy of 7.1 Installed Driver Disk that came with card. Reboot. Installed open transport 1.3. Reboot. Opened TCP/IP, manually set my IP address (I believe inaccurate time can have an effect on getting dhcp leases) - You can get the TCP/IP info from another machine on the network, just change the IP to something unused Started Fetch, ftp'd to my laptop. It can be as "simple" as that. I've learned to leave all the other networking control panels/etc alone.
  16. Yes, please do! Always fun to follow along. Good find - looks like a fun project.
  17. I really do appreciate the guidance. I personally feel uncomfortable with my current knowledge to pick exactly what I need. I ended up going with a Console5 kit as it's the easy way out (found they list all the exact info on their wiki pages). And honestly the price was within $2. I'm glad I went through everything as detailed as I did as now I have a map out of every part, value, etc for when the parts come. Now we play the waiting for capacitors game.
