  1. That's a bummer. Sounds like it is shot. I have yet to be able to fix an HD head no matter how much tweaking. I am sure it can be done but the precision needed to get it in just the right spot is not something that us tinkerers could likely do. Sorry I have no other ideas.
  2. The EZ 135 was probably my favorite SyQyest Drive. I still own my original I bought back when it was that VS Zip drive. If you find one cheap enough even if it is untested, it might be worth it. Most people don't have the SCSI interface anymore to test with it. You might also try posting a wanted in the trading section here, maybe someone has an extra they no longer use. That said the drives can be finicky sometimes. Have you tried powering up the computer with the drive on and a cartridge inserted? Sometimes they won't mount unless it reads it at startup with a cartridge in
  3. Very Nice work! Thanks for sharing the detailed log and pictures.
  4. I love these printers! They are so simple and yet after all these years they still work and that is amazing. I have had countless modern Epson's and Cannon's that die after only a few years. Nice thing about these is you can still get cheap ink cartridges and you can refill them super easy. It's a great printer for classic Macs that you want to print with and get decent results. I don't remember what the difference between the 2400 (which I have) and the 2500 were other then I think the 2500 uses a separate power supply vs a built-in on the 2400?
  5. Very cool! A Color Classic has been on my want list for some time. I pretty much gave up on that, though. So it's nice to see someone get a good one.
  6. Oh yeah, forgot about the keyed DIMMs. The eBay seller apparently didn't know what he took it out of. Hmmm..
  7. There is one on eBay with the same Apple Part Number and the listing says they pulled it out of a Quadra 8500. Haha. https://www.ebay.com/itm/Apple-256KB-L2-Cache-820-0672-A-/114208727907 So probably for a Power Mac 8500.
  8. That really sucks. I usually try to match the series or at least get caps that are made for switching power supplies. Who knows what the ripple current is doing as I am no engineer. I think with PSUs or analog boards on Macs that don't support soft power it is probably not as big of a deal but it seems the ones that do have soft power it might be more crucial. I could be wrong as I am only going by what I have experienced myself.
  9. Perhaps you should try the audio out jack on the 6100, not on the CD-ROM drive. Have you tried that?
  10. I have a SuperCard Pro and a Kryoflux if you need someone to image it. Try it out with some Copy and image programs first and maybe you will get lucky. Come to think of it I will look through my software to see if I have a copy too. It could be the Amiga version but I'll check when I get home.
  11. The only problem I have with LR44 batteries is they tend to leak as they age and go flat.
  12. Will the card physically fit in the IIsi? I have wondered that myself...
  13. Wow, that is super cool. If you run into any other colleagues that need to downsize and you can't store anymore, let me know.
  14. Very cool that you kept your machine. I bought the same model back in 2000 too. I replaced my first G4 with it that I bought in late 1999, which was a G4 Yikes 400, before they lowered all the speeds by 50mhz because of shortages of the CPU, IIRC. Did you restore with the correct restore disks because these G4s came with Mac OS 9.0.4? Not that it matters because 9.1 - 9.2+ is a better choice. A number of years ago I found someone that was selling a very clean G4 dual 500 gigabit for $20 that was used in an office and snatched it up. I still have it and it is one o
  15. Thanks for the info. I will have to try the blanks that I have again. I couldn't get them to fit quite right so I thought they were using a different design.
  16. Thanks for making these. I don't have any bad ones yet but it is always good to have spare parts on hand. Considering the alternatives on eBay this is a great deal even with shapeways charging $9.99 for shipping which you could probably add this to an existing order to combine shipping and save more.
  17. Thanks for that. I edited my original post to make it clearer as to what i am looking for. I am looking for the blanks that go in the Rear Expansion Slots. The blanks you remove when you ad a NuBus card.
  18. Does anyone have any images or dimensions for the rear expansion slot covers on the PowerMac 8100? I guess it would be the same for the Quadra 800/840AV? I can't seem to find any information anywhere as to the covers. I know they were unique covers and clear or frosted IIRC. My 8100/80 came with one and I can't seem to find it. I must have taken it out and like a dummy didn't put it back in. I would like to model replacements if it hasn't been done already for 3d printing. Thanks!
  19. Yep I would do the same. Fortunately I have not owned a Mac model that had the battery with leads soldered on. One of the revisions of the Apple IIGS came like that and I would replace it with a holder too. None of my macs came that way. I did get one Mac used, a PowerMac G3 Tower beige that had a leaking battery that destroyed the battery holder and corroded the frame. It didn't do any damage to the logic board though, thankfully. I forget the brand but it was not a red bomb. On that Mac I soldered in headers so I could unplug the battery holder and put leads on it so it could be reloc
  20. I like the idea of a dummy cell. That said I don't see a problem buying the correct battery. Amazon sells the 3.6v battery in several brands, thankfully no maxell red bombs. I have used EBL brand and they come in (2) 2 packs (4 batteries) for $8. $2 a battery is much cheaper then they used to be thanks to the fact that they are used in a lot more electronics today. They claim they don't leak or rust and claim a 10 year shelf life. I have not had any problems with them. Of all the solutions above if the batteries were really that hard to find and expensive, I would use the
  21. Gotcha. I have a 25 pin to mac serial and a 25 pin null modem adapter so I could hook it up but like you I haven't really looked into the software aspect yet. It would be cool if there was some sort of spirograph like generator that supported this.
  22. What cable are you using? Mini-Din to 25-pin serial and a Null modem adapter? I have not interfaced mine to a Mac only a DOS computer and an Amiga. They have modern libraries and drivers for interfacing with modern systems. IIRC InkScape has support for HPGL too.
  23. Wow, That is cool. Looking forward to seeing this in action.
  24. It is probably 1200 baud and looks like a standard modem. I did an FCC ID search and it doesn't have any details other then it was granted the license to Capetronic in 5/1988 so yeah probably 1200. On the BBS front, I don't think there are that many BBSs that actually still support dial-up as most have moved to Telnet as the connection means. Cheap Wifi modems for classic computers work great for this.
  25. Yeah sounds like you have done the same thing I ended up doing a few years back. I have a drawer full of various size pads and bumpers and some have worked better then others. Mostly 3M but I have some other brands from stores like the Home Depot. I have had mixed results with these things with some of them actually sliding around and not staying in the place they were adhered to, even after cleaning the surface with isopropyl alcohol. I noticed on my 8600 that it had lost all of the feet. I don't know what happened there as it was sitting in storage for 10+ years. I noticed o
