  1. It should be quite possible to do a variation with digital video out, incl. color support. At a bare minimum we could probably integrate Toby, the Macintosh II's video card, for 8-bit 640x480, because that card is about as simple as possible and very well documented in the Designing Cards and Drivers for the Macintosh Family book, IIRC, but with some ambition maybe we could even clone the Micron Xceed 30 and run up the score with grayscale on the internal CRT. Of course my mouth is currently writing checks I definitely can't cash, but I'm also amazed at the amount of skill we've assembled here
  2. Hey, this is a different take on a project I was considering taking on! My main focus was to output color to a modern external display rather than provide grayscale to the internal one, but this still sounds very interesting, and I definitely don't have any engineering experience in my project. I was hesitating about including an FPGA in my project, because I feel like it should be possible to go without it, and leaving it off would definitely lower the price. But more power to you if you have the resources to handle that. Any chance your SoM has an exposed HDMI port we can try an
  3. Silverlining included a First Aid program that actually worked for me, unlike the one on my System 6 disk. (Is that locked to Apple hard drives again?) Verify and repair and it was good. I ran Silverlining’s short tests to see if anything else would go wrong and they didn’t. So, yay Silverlining! I’ll update again if anything goes wrong in the near future, I’m about to start a project on this Mac that’ll keep me running it for a while.
  4. It booted! It seems to be working, except: all the text is backwards. But it all starts in the right place, so most of the text just gets clipped immediately. Well, I guess I’m about to run Silverlinings so wish me luck.
  5. So I booted up my SE/30 I've left alone for a bit. I put in a younger (ca. 1995) hard drive I had laying around last time I messed with it, which I used LaCie Silverlining v5.7 to initialize and install a disk driver for. Everything was working fine as of then, excepting quiet audio and display distortions whenever the hard drive or floppy drive was in use. (it hasn't been recapped) This time, I booted it up, I found that I left System 7.1 installed last time I used it, but the software I wanted to mess around with (THINK Lightspeed C 3) expects System 6. I figured that's why the debugger wasn
  6. @balrog These are beautiful, I almost forgot you mentioned you had them laying around somewhere! Thank you very much for your contribution.
  7. I kinda figured that any card that'd come close to modern resolutions would need acceleration. I was hoping that this discussion would decide on 030 PDS because, selfishly, I've got an SE/30 myself, and also, the increased bandwidth might make higher resolutions more possible. But honestly, the more time the CPU is sending data to the PDS the less time it has for other calculations, so it'd just slow down the rest of the computer even more than a fully saturated Nubus. Gotta keep your resources in mind, I guess. No wonder Apple seems to heavily imply that even PDS cards should be talking pseud
  8. So, let me get this straight: in practice, a video card for one of these Macs is, from the Mac's perspective, a RAM expansion that includes one or more frame buffers, and then components that read those buffers and sends them to a display? And that expansion attaches to the rest of the system through either Nubus or PDS? Does the video card have any other necessary responsibilities? Is it possible to make bare minimum hardware that uses internal RAM as the framebuffer like the IIsi? Obviously it's most likely worth *not* doing that, just getting my head around the problem space.
  9. Wow, that's an amazing document you've got there, Bolle. I'm really starting to develop an appreciation for vintageapple.org that I wasn't expecting, they do some amazing work collecting and digitizing all of that. Obviously this isn't going to be a very inexpensive project if I do decide to do it, but that's worth it to have more to tinker with for sure. I wonder what the practical maximum resolution one of these machines can handle is? Could I get 24-bit color on a 4k display with a big enough buffer? I don't know, but I hope I'll find out!
  10. Are you offering to sell it? Give me a price and I'll consider it, for sure. I'm just across the rockies from you so shipping should be reasonable too.
  11. Oh man, that would have been cool. That's a good thing to keep an eye out for just in case, thanks.
  12. What's the cheapest way to get color video out of an SE/30? Even 256 colors at 512x384 would be perfectly fine. I find that my interests in this computer are more often limited by lack of color than lack of hardware on this. And I could just pull out my Performa 630CD for that, but it takes up so much more room than a compact Mac. On a side note, has anyone attempted to make a modern video card for classic Macs? It really seems like it wouldn't take much hardware to make a very impressive video card for these. I can almost imagine the components in my head well enough to consider p
  13. That label thing is a kind of funny piece of trivia. And you all were right, as soon as the TE jumper was set up, everything ran perfectly. Wow, this machine boots fast with a hard drive.
  14. Okay, that's good to know. I've managed to track down the jumper guide for this drive and I'll see how it's configured later today. Edit: And thanks to SE30_Neal for getting this discussion started. I will try the copy of Silverlining I've got lying around or Lido, if the termination isn't the issue. I just would have preferred Apple's tools if they would have worked.
  15. Okay, good to know! I know that the external casing it was in before could select the SCSI ID, and a trace of Silverlining from the last Mac to use this drive showed that it was recognized as 0 when installed internally, so I just assumed it was automatic. What really confuses me is that the label for this drive shows jumper positions to put it in master, slave, or cable select mode. If I'm not mistaken, that's IDE-only, right? But this is certainly a SCSI drive, I had no trouble at all with the ribbon cable inside the Mac. As I understand it, a lack of termination wouldn't just be
