  1. Thanks for posting these! Very interesting to see some of the old advertising. I was shocked at how expensive everything was, but then remembered that the exchange rate would have been drastically different in the mid-1980s. I think it was around 230 yen to the dollar back then, versus 106 or so right now. Not sure what that means in terms of the actual price of these things for Japanese people, but since they were imports I have a feeling they would've been pretty pricey. I liked seeing the IKESHOP ad (the one with the bride & groom) since I remember visiting that store in Akihabara back
  2. Thanks again to Stephen for sending me a set of replacement ROMs (completely free!). I have 7 compact Macs of various types, but one of them has never worked since I received it -- a Mac Plus. I was able to confirm that the ROMs were the culprit a while back by swapping in some known good chips, so when Stephen's chips arrived all I had to do was pop them in and it booted right up! It's a super easy fix in that sense, but for a long time it wasn't obvious to me that the ROMs were at fault, and getting replacements is also generally not simple. But I'm hoping the guide Stephen posted will help
  3. I found a "Mac Bottom" on eBay recently for a fairly reasonable price. I don't have an external SCSI hard disk, so I thought I would take a chance on it, even though the seller didn't really seem to know whether or not it worked. When it arrived, the fan inside had broken free of its moorings and was rattling around, and there were no signs of life when I plugged it in. I did test the fuse and it seems fine. I took the drive out of the enclosure and put it in an SE and it booted right up, so worst case scenario I now have another working SCSI hard disk, but I was wondering if anyone else had a
  4. I’m interested (assuming you mean ROMs that you have already created that just need to be swapped for bad ones).
  5. I think putting the LCD behind the glass of a CRT just makes it look more legit than having a flatscreen installed in a compact Mac case.
  6. I found my other board, and it's the other type:
  7. Yes. It looks to be slightly over 7mm (the curve of the metal frame makes it difficult to be exact).
  8. I'm not very knowledgeable about capacitors, but here are some photos of my boards if it will be helpful (I also have one more that I can't find at the moment). One of mine is a Japanese board and one is American. I don't see anything else that looks like a capacitor to me.
  9. I can try and check my boards later, but do these caps ever go bad?
  10. These are such fascinating machines. Love this thread.
  11. I would definitely be interested in a set of ROMs. I verified tonight that the issues I was having with my Plusses is due to the ROMs.
  12. I did try swapping the RAM earlier but neglected to mention it. But I've never taken out a Mac's ROM chip (and wasn't even sure if they were socketed until I checked which ones they were). After doing some swapping around of chips, I can say that it is definitely the ROMs that are at fault. When I put the ROM chips from the working Plus into the non-working one, the non-working one starting working, and vice versa. So I decided that I would put the good set of ROMs into my accelerated Plus, since it is my favorite and WAY faster than a normal one. That entailed removing the upgrade board, whic
  13. How did this work out for you? I’m wondering if a problem I’m having with two of my Mac Plus units might not be related to the ROM since the symptoms seem similar and I’ve narrowed it down to a logic board issue.
