    3D-Printed Objects

    Well to be true.. I would just need the badge/part in it's shaped form - even without the printing. I know it's a hard level 3d printing every detail and especially these secure points and curved shape - I would be ok with a little afterwork, grinding and sanding. My printer is capable printing very small and round structures - it's worth a try. If I would have a spare logo plastic, I would mail it to you...but actually there is no spare case to take it from

    Hmm I just want to ask again does anyone every tried to recreate the Macintosh Color Classic front badges/logos? Unfortunately I lost my small logo/badge after I measured it

    LC 475 won't startup after recap...why?

    Hmm that U29 looks quite clean and good to me ... damn, I'm not sure, if I can desolder this IC will a ordinary heat gun work or kill the chip? ...and I already consider that board as maybe toast ..I did one really bad mistake here: this board was pre "tried to repair" from the former owner - usually I don't do/accept repair request on already repair attempted boards @Bolle - is there a chance, that you may want to take a look on that board? I probably will include my Micron Xceed Grayscale Macrocolor card for some checks/repairs too ;p (I got me another SE30 and maybe will keep that Grayscale kit as it is really a rarity - I already have a green, amber/yellow and well why not even cool Grayscale compact Mac SE30 in my collection ) - I don't want to f**k up this rare card and due to your own experience I trust your work Marcus
  4. Hi friends, I just recently recapped a LC 475 logic board. Usually it's nothing fancy about - did it dozen of times. But this particular one won't talk to me, even afte a good recap. It just had bad caps, no battery leakage or so... If I turn on the machine, the fan will start and the hdd starts spinning. But no chime, no display I did wasch/clean it twice. Any special vias I have to check for continuity or are there any knows culprits maybe? I mean.. I'm not much into LCs and stuff that aren't compacts or Lisa or Quadra 700/840 machines ;p I did try to repair that board for a collector friend... Any suggestions or ideas are very welcome Marcus

    Mac10 ext. HDD Pinout & drivers needed :D

    Oh yes, there can be damage done if the 5V / 12V line on the serial cable goes to the wrong line of the Mac10 well.. I will wait and hope for some good schematics/pinout before I try my luck
  6. Hi Friends, I just dig out my old MAC10 (by Paradise Systems Inc.) external serial hard drive. It once came with my Macintosh 512k. Sadly I can't find it's serial data cable anymore after our last moving in 2019 Does somebody has the same drive and/or can tell me the serial pinout/wiring to get it hooked up on a Mac 128/512k? I want to solder me a new data cable ... a common serial 1to1 cable doesn't work. Ah and if someone may also has the service/user manual and a dump of the drivers diskette - this would be rocking awesome ...Google didn't help much...no information found about this thing - nowhere Many thanks

    mac plus with weird harddive

    OMG, I know, I know I shouldn't dig here in this "grave" ... but I have a nice Mac10 external Harddrive but I lost my serial cable during our moving we did in 2019 You don't know the serial wiring from teh drive to the Macintosh 128k/512k? I couldn't find anything in the Internet so far Stay safe & healthy, Marcus

    Lisa AC interference coupling?

    ah, you have to make sure, that no other old gunk of the old leaky caps are still anywhere on the board. This stuff tend to sneak under parts you won't suspect I once had very ba dissues on a Mac Plus analogboard - old residue did short other components ...

    Lisa AC interference coupling?

    hmm.. something is heavily buzzing inside your PSU how did you cleanup the PCB after removing the old parts?
  10. Yeah Playing with an X/Profile will be a task for the future till then I keep me happy with original Widgets and Profile drives. Next project will be my IDEfile. As I stated above, the Screen gibberish was instantly when I turned on the Lisa. It was due faulty H-ROMs not the mismatch of VSROM or OS issues But yeah, it was anyway fun what all could and did happen due playing with ROMs.
  11. OMG!!! My Life-Savior just see what you did to me This was such a happy moment ... unbelievable... I tried several official and inofficial sources - all corrupt - thank you so much ...even my Mac Works/Macintosh OS is booting just fine from it's widget drive last step will be a proper recap of the video board and the screen calibration.
  12. Ah, no - my other Lisa is a 2/5 with F-ROMs and in this machine my "new" 341-0229-A VSROM works without any issues. But if I put in these H-ROMs in this one too, I get the same result as on my Macintosh XL
  13. Ah right well I checked the VSROM also vice-versa I just used my other Lisa 2/5 to cross-check every Chips the VSROM works just flawlessly in my other machine - the H-ROMs do not work properly on the other machine too
  14. Hi friends what do I miss here? ... I just burned me the last Lisa ROMS, the H-ROMs (341-0175-H & 341-0176-H) on suitable 2764 ROMs but I only get such gibberish on the screen when I plug them onto the CPU-Board. Here's also a short video of my Mac XL/Lisa showing what I mean: https://youtube.de/watch?v=d93gUHUsrwM There is even no startup-beep. When I put back my original ROMs (341-0346-A & 341-0347-A) everything went back to normal. These are the ROM dumps I used: - http://www.bitsavers.org/bits/Apple/Lisa/firmware/ - https://www.macgui.com/downloads/?file_id=14062 I already did this: - removed the special CRT converter/transformer that sits near the screen inside the cage - cross-checked the Chips by dumping my originals, burned them onto these and different other EPROMs again - they work flawlessly - I also managed to get me a suitable original VSROM 341-0229-A for the CPU-Board, but this didn't help - checked for visible damages on all parts - scratched my head till loss of hair... Is there something I may forget to change when changing to the H's? Or are these ROM-Dumps somewhat special to burn? My Eprommer is a Willem Universal Eprommer PCB50B (parallel port), used under Windows 98SE I also welcome, if someone would be so kind and just dump/image his or hers H-ROMs for me Any advise is welcome
