  1. Well, as things become more scarce over time they become investments and that means they go up in value. This is not unique to the SE/30, or even to computers. It is applicable to pretty much every material thing in existence. If scarcity and demand are both high, then prices will be high accordingly. The last time an SE/30 was worth $50 is quite a long time ago now. There are options. Non-working SE/30s do come up for low prices, you just have to be patient and look out for them. Performa and LC models still fetch low prices, and some of them are decent machines IMO. Perform
  2. It's not impossible to find a replacement CRT, they come up on eBay or you can take one from another compact Mac (sometimes the yoke may need to be swapped, a pretty easy job but will require realignment/adjustment of the CRT). I recommend contact cleaner to help make the logic board connection less stiff for next time.
  3. I like the idea, but I think executing it will be difficult to get right. I'm no expert on this, but as I understand it, there are several pretty big challenges to overcome. Tooling/manufacturing cost to produce a good quality case is very expensive and there is precedent for this from @maceffects SE case project. I think ascertaining demand for this type of product would also be difficult, it would probably be a lot less than you'd initially think. A lot of the PCI-based Macs can be fairly easily transposed into ATX cases, there are a few examples on this on the forum,
  4. I have produced a BOM for the SE/30 logic board: https://docs.google.com/spreadsheets/d/1CAzGjHxQaQrduQC-hQ8sB2I6Y56fUlCWdJMCUDho0NE/edit?usp=sharing As Bolle said, it makes sense to take most components from your donor board, including all the passives on the back of the board. Certain components will be easier to buy new rather than salvage from a donor board, for two reasons: 1) Some components are tedious to remove from a donor board, especially without the right equipment. An example is the PDS connector. 2) Some components on your donor board m
  5. Yup, I don't usually bother testing systems before a recap anymore, it's just easiest to recap and then start from there.
  6. What voltages are you getting from the PSU conversion? You may need a new wiring harness as well, to go along with the new PSU. This has been a known factor in even a newly converted PSU not giving good voltages in these machines. Have you tried with less stuff installed, e.g. MacCon on its own, Pivot on its own, etc.
  7. This looks promising, please update us when your revision is up as I would like to try it. Thanks for doing this!
  8. Which part numbers are you looking up? I can still see SWIMs on there.
  9. You may find this page that I wrote interesting: https://se30forever.com/fpu.html
  10. Oh that's a 'good' one, very extensive damage there. It will be worth cleaning it to see how it comes out, but it would take a lot of work to get it working again. It is worth keeping the board because there are custom ICs that could be salvaged in future. Thankfully LCs are not that hard to find, so now you just need to find a good logic board. Can you post some pictures of this please?
  11. These tabs often break, as they are brittle plastic at this point - so I would also suggest pre-heating them with a hairdryer first which will make it less likely that they snap off.
  12. The SE and SE/30 are a warm grey platinum color. Hartmut Esslinger disliked the beige color used for the Apple II, III, Lisa and original Macintosh. So an off white color was used instead. In PANTONE's color system, the color used for the SE and SE/30 is probably closest to 420 or 421. According to Apple, "Apple does not normally use PMS color charts or Pantone color numbers to designate the platinum color that is now the company standard. Our platinum color number on a coded PMS chart is somewhere between 420 and 421, somewhat closer to 421. (This depends on the age of the chart and the light
  13. Looks like it's suffering from the marbling effect that you often get with retrobright which IMO is worse than the yellowing itself, but each to their own... As has been mentioned, pop the Apple logo off before you subject it to more retrobright - the hydrogen peroxide will affect the colours in the logo.
  14. Here's what the IOSB chip looks like currently...
