    Docs needed

    Greetings all, In addition to SE Mac variants and a Quadra 650 I have a G3 beige desktop machine that I know little about: It has the 300MHz CPU, 760 MB memory, ATI video card, CDR, ATAPI ZIP drive and a 9+ GB HD. I believe the "personality" card is the "wings" variant; it has RCA and S-Video...

    Mac SE CRT issue

    Working on a Mac SE (same as was referenced in PSU issue post earlier).  After substituting a known-good PSU I assembled the computer and powered on, with the back shell removed for observation.  Observed the following:  No chime, black screen and a hissing, crackling sound.  Immediately shut...

    Sony CR44 power supply repair... or not?

    Been reading  http://www.ccadams.org/se/classicmac2.pdf and also Pina's books for info on repairing Mac SE power supplies.  I have a Sony CR44 that tests the -12VDC lead as -8.5, +5VDC as 5.3 (both lines) and +12VDC as 13.5 and 14.2 respectively.  I have already recapped the PSU and am...

    Levco / SuperMac Prodigy SE accelerator and utility

    About a year ago I bought - on eBay - a Prodigy SE accelerator board, which I intended to plug into the processor expansion slot on my SE which has a SuperDrive.  Not knowing much about compact Macs or anything about the board, I put it in a drawer for safekeeping until I was ready.  Recently I...

    Source for flyback transformer?

    I have an SE/30 that I am in the process of restoring.  I bought it from an academic and it immediately displayed problems: jittery video.  On the advice of those who knew more than I, I sent the board out to be recapped.  Back from recapping and that much poorer, I find the video problem was...

    SE HD issue?

    Yesterday I tried to boot a recently-acquired SE Mac and am experiencing what I believe is a hard drive issue:  Similar to the description on http://www.ccadams.org/se/boot.html, the machine has an internal HD but will not boot from it; I can boot from a floppy (OS 6.0.8) to a desktop but the HD...

    Mac SE FDHD ROM / SWIM PROM clones?

    Is there an EPROM / EEPROM which has the same pinout and capacity as the Macintosh's masked ROMs?  I would like to copy my FDHD's ROMs and equip another SE with FDHD capability.  Aside from the MFM 1.4 drives, I believe these are the only differences between the machines.  Am I correct? -CH-

    SE serial ports diagnostic and repair

    I acquired an SE about a month ago - first one I have owned - and recently posted here a question concerning printing from the SE.  (I have a StyleWriter and couldn't make it work with the SE / OS 6.0. 8-) . Since then I have been running tests on the machine and today ran Snooper 2.0, which...

    Printing with non-Apple dot-matrix printers

    Hello!  I am a first-time poster here with a question specific to printing from a Mac SE that is running OS 6.0.8.  (I also have other Macs: SE/30, Quadra 650, beige G3 desktop). The SE is recently-acquired and my first compact Mac, about which I know comparatively little.  I am currently...
