  1. I have a IIci that has been an old friend for decades. I recapped it a few years back and it has been working great, until now. Now it hangs while booting. It starts from the keyboard power key, chimes nice and loud, then the raster appears and looks good, but no happy mac face, no Welcome to Macintosh, and it never accesses the disk. It will stay like that forever. I never get any death chimes. If I try to reset PRAM with Cmd-option-P-R, it never gets around to noticing that and there is no second chime. I think it is hanging before it looks for that. The board still looks clean. I have r
  2. Probably, you have figured this out by now, but... The MDS linker placed the application globals 256 bytes below the a5 boundary. The MPW linker put the application globals right below the a5 boundary, without any cushion. The ROM call InitGraf expects a pointer to the 203rd byte of a 206 byte area for the QuickDraw globals. Because MDS put a 256 byte cushion below the a5 boundary before the application’s globals, MDS programs could call InitGraf with a pointer to a long word four bytes below the a5 boundary, as in your example For the MPW assembler, you must explicitly
  3. I had to replace the PRAM battery on my Powerbook 180. It started out just failing the remember the date and time when I would remove the main battery. I knew the PRAM battery was bad, but it seemed like a hassle to replace it and I let it go. Then a few weeks ago, it got worse. It started randomly changing the date and time every time I clicked on a window or hit a key. Something had to be done. The PRAM battery on those is soldered onto the interconnect board. It's a coin type 3 V rechargeable lithium battery with solder tabs made by Panasonic (VL 2320). When I got the interconnect b
  4. You have TMON installed. It's a debugger. That's it's icon that is the last icon you see in your startup screen. If everything is ok, you should be able to get out of it and back to the Finder by clicking on the words ExitToShell in the second screen you show. I don't know why you are falling into TMON at startup. Usually it is activated only during a crash. Maybe something else is causing you to crash, and TMON is getting activated by that. TMON is in your Extensions folder, probably in a folder called TMON folder. If you remove it from the Extensions, TMON won't load. However, yo
  5. I routinely use MPW version 3.2.3 under system 6.0.8 with no issues on a Mac Plus, a IIci and in Mini vMac.
  6. Your filter function will be called by the dialog manager. You don't really have to declare it to be anything in particular, you just have to make the function you want and pass its address into ModalDialog. The Pascal declaration you have written tells us about how the stack will be set up when the filter proc executes. The stack frame (pointed to by A6) will consist of the previous A6 (at (A6)), then the return address (at 4(A6)) then itemHit (8(A6)) then theEvent (12(A6)), followed by theDialog (16(A6)) and room for a boolean result returned (20(A6)). When your filter function execut
  7. The original solution to this was BinHex. It hex-encodes a file so it is ASCII and can be transmitted over practically any protocol. I think you could use an old version of Stuffit in your emulator to encode your .sit file as binhex. You get a file with the .hqx extension as a result that can be decoded in stuffit. There was originally a program called BinHex that just did the .hqx encoding. The first Mac users encountered this problem when downloading programs from CompuServe. They had to download BinHex from CompuServe, but they couldn't decode it without having BinHex. The solutio
  8. Very cool that you are using a Quadra to control a CNC machine. Would be great to see a picture.
  9. I suppose you have already tried rebuilding the classic desktop. In the preference panel for the classic environment, start classic then go to advanced and click rebuild desktop.
  10. There were some great programs that never made the system 7 transition. Among word processors, fullwrite professional stands out. Trapeze was a great spreadsheet. There has never been another like it. MacSpin was an amazing visualization program that never was matched. Superpaint for graphics. Great desk accessories: the canvas v2 desk accessory, disktop, expressionist (equation editor) vantage text editor, number crunch.
  11. The power supply on my faithful Quadra 950 has failed. Went bad while I left it unused for a couple of months. It no longer has any voltage on the 5V PFW or TRKL lines. Can't properly test the rest of the power supply, because those are used to start it up. I have opened it up, but all I've done so far is to check the fuse. It is intact. Yes, I'm sure it's plugged in properly. Does anybody have a circuit diagram for this power supply or any experience fixing them?

  13. You should make sure you have a copy of the full developer version of hypercard version 2.x (preferably 2.4). Apple bundled a hypercard reader with the operating system, but to make new stacks you had to buy the developer version. There were a lot of books written, but this was mostly before the era of pdfs. But to get started, the regular Apple hypercard manual is pretty helpful. Do a google search for 0340617Ahypercardi.pdf. This will get you the manual and a lot of other useful stuff.
  14. looks very cool. Have you thought about using HyperCard? It was used for this kind of thing in it's tIme, and late versions had good QuickTime support.
  15. MacTCP used the standard device driver calls (Open, Close, Control, etc) to control a driver. There was an SDK called the MacTCP Developer Kit, which I think might still be available from Apple's ftp server (try http://mirrors.vanadac.com/ftp.apple.com/developer/Development_Kits/). I suggest you start with the article by Steve Falkenburg in issue 6 of Develop magazine. If you don't have the magazine or developer essentials disk 6, you can see a text-only version at: http://www.mactech.com/articles/develop/issue_06/p46-69_Falkenburg_text_.html
