  1. Past hour
  2. I know well enough to not try force a 72pin stick fit into a 68pin slot etc that sort of thing but even then I was a little curious about it after quickly rechecking the various ram/cache/etc things I had managed to selectively amass since late last year ... and I had to wonder if its no harm to test them in any systems or is there actually cases of where at one point a rom from one system has the same physical connector but really different electricals to a cache from another system?
  3. Yes the 10u tantalum was shorted, which burned the resistor near it. For the erratic no video I think the battery was a bit flat, I changed it and it's doing great now
  4. You should be able to just use MODE32 for this on a IIcx, no need to muck with the ROMs
  5. Hiya! Some three weeks ago I came across a local auction for a Mac IIcx. It was described as "powers up, not tested". The set included the computer, power cable, SCSI cable, an Apple apple 590-0161-A DB15 display cable and a ball-less A9M0331 mouse. I thought it looked like an interesting project, I've always liked the compact design and the final winning bid of 37 EUR was not bad at all I got the machine couple of days later, it arrived well packed. The speaker-assembly was loose, but had caused no damage. The only thing missing was the front panel reset/interrupt-but
  6. Today
  7. Hey, JDW. Got your email. I gave away my closet full of old Macs a few years ago to a young collector, but I kept my much-hacked first 128K Mac. If I can figure out a way to get files off it into a modern Mac, I'll post the MacMovies apps, some demos, and other early stuff. IIR, I used to use AppleTalk over PhoneNet to a G4 Cube, reboot the Cube from OS9 to OS X, and copy via ethernet to a modern Mac. Of course these files and demos won't run on a modern machine, they are written in 68K assembler, but if there is an emulator they might work. I haven't kept up with that sort of thi
  8. $199 on ebay https://www.ebay.com/itm/174658514127 What happened to this project? I have the tango card, but can't fit it, as I don't have a PCI riser.
  9. I’m waiting on a fan to arrive so we’ll see how it goes. What I was referring to was the loud horrible whine coming out of the speaker. With no fan and case open it was very obvious, modulated by the SCSI access (using SCSI2SD, no motor either). All gone now new caps are in totally silent (until the fan goes in).
  10. Definitely a project I am interested in! I would love a solution to drop an LCD in the SE and have a nice power solution like this. If my SE had that kind of weight reduction I'd be able to use it more often
  11. What fan did you use? A modern Noctua? When so, which one? Or is it fanless?
  12. Oh, well noticed. That does look proper dodgy.
  13. Today, I ran across forum member @H3NRY's website while Googling and found this amazing work: http://www.audioimprov.com/AudioImprov/Macintosh/Entries/2012/4/30_MOVIES_MADE_IN_1985_%26_1986.html Being curious about his app, I wrote him an email just now. I'm quite curious how he did dithering related to how MacFlim does it. The amazing part is, his web page says he was able to get it to run full screen at 30fps.
  14. Re-capped and the machine is totally silent. I'm surprised.
  15. Good to know the troubleshooting steps for this. So what was wrong on yours, just replacing the resistor and 10uf capacitor near the resistor?
  16. Hi, thanks for your helpful advice! I won the auction and hopefully it will arrive next week... Since the seller claims that it intermittently boots into system (and other times shows the symptoms above: jail bars or random dots) I fear that that there might be problems with the UEx chips, rather than a broken trace since in that case it will not intermittently boot into system...If the chips fail, that will requires desoldering those tiny chip legs ( I saw some videos about the desoldering alloys but I really doubt my skills)... but once I receive it, I will first chec
  17. Hi @Andrew, I think you got me wrong here. I'm showing how to change your image size by using the different physical size to my advantage. In the process, I'm filling up the whole physical size with a Mac Volume, to prevent exactly what you mentioned. I guess that the physical size would pose a problem when continuing to use you 512 MB partitions like that. Generally speaking, what would be the correct physical setpoint for your initial MagicSD? Is it 1 GB (both partitions together) or does it need to be set to an exact size parameter like the start sector?
  18. SuperMac made it. E-Machines was just a reseller. They also sold a mini dock that was a rebadge of Apple’s, but had Ethernet in it instead of a modem pass-through. Much more useful than their junky ExpressModem tech.
  19. To explain, because its been asked, the 68LC040 Apple chose to put in the 540c did not have a math coprocessor, which meant that you could not do multitrack audio in applications like Sound Edit 16, and other software for making music, which drove me nuts when I was a kid because the 540c was my first and only computer at that time. I think soldering in a full 68040 would be worth it just to have finally fixed a truly horrible design decision Apple made for the North American market. Why they did not sell the 550c in America is a different discussion.
  20. Yesterday
  21. I have a bigger project going on, of replacing the CRT with a LCD. Not with an Arduino or a Pi and a converter board, but one board to interpret Mac video and drive the display directly. It's a big job because there are about five different voltages required - boost/buck regulators, coils, critical layout etc. - the FPGA decoding the video will also have to manage a safe startup/shutdown sequence since the data sheet has dire warnings about which voltages may be applied when and in what sequence. Anyway, this power supply is a step toward that. With no CRT in the machine there's no
  22. I'm in the Portland, OR area if you need some help. I also will be selling an SE/30, an 8100/100, and a PowerCenter 150 in the very near future in case you miss the one you're looking at now.
  23. I'm between 3D websites. Pinshape _sucks_. I have a few things published there but all they seem to do is forward me spam about Mumbai Escorts. Have uploaded to Thingiverse but as it's a new account they are taking some time to show my uploaded design. For now it's attached. Lower PCB retainer.STL PCB holder.STL
  24. If I could put a real 68040 CPU into my Classic II, that would be great, but my opinion is that all FPGA and PIStorm stuffs are cheating... From my POV.
  25. Hi @AVE - Michael and thanks for your feedback and comments, I am pleased that you found it useful. I enjoyed watching your video. I am however concerned because the physical partition is 2GB but on the file system it is still reported as 512MB. I believe it will cause problems when the partition fills up with data (more than 512). What I suggest you do is the following: i) delete disk2.dsk ii) with a tool (e.g. dd) extend the file disk1.dsk to at least 2GB size. If this does not work, you can start from scratch (easier case - one partition):
  26. I potentially have a compact Mac I can get in Portland, but I'm in Northern California. I can arrange payment with the seller, but I need someone to pick it up for me. I will be heading to Portland in the nearish future, or we can arrange shipping if that's better. Please post back if you're willing and able. Thanks!
