    Tip: Checkerboard after Recapping Classic

    Hi Recapped my Macintosh Classic, but it booted without sound and gave me this nasty checkerboard pattern. I was worried that my soldering skills were not perfect and somewhat the caps are misalligned. Cleaned the mobo with IPA. Nothing, just still the bootscreen for chess fanboys. Tried power...

    Reduced eye strain text editor for classic Mac

    Hi, I am thinking about using my old Macs (512k, Plus, SE/30) as distraction free typewriters. Is there any chance I could use white color characters on black screen to reduce eye strain? I think in mid 90s I used telnet or terminal emulator program for my old PowerBook 170 that had this...

    MacAuthor anyone?

    Hi, while browsing my father's old Mac software archives from the 80s, I came across a pre-release version of MacAuthor floppy with xerox copied manual (in English).

    PowerBook 170 with e-ink screen

    I miss my PowerBook 170 I dont have anymore and consider buying PB 170 or PB 180. What scares me off is yellowed LCD (tunnel vision is another story), is there any chance to reverse that?

    Hi, since obtaining the 9 inch CRT for compact Macs is getting harder and more expensive, I am thinking about using CRT from 9 inch mono VGA monitors still available around. Will they work after adjusting screen?

    Macintosh SE black screen

    Hi, my recently bought Macintosh SE arrived in package safely. However when I tried to power it on, all I got was black screen. When I tried to tap on the side, it gave me a startup sound, but no video (already tried brightness nob). Before shipping it was confirmed working, the seller showed...

    SE and noise on screen

    Hi, I replaced the broken CRT with the working one „borrowed” from my Plus. It works apart from the fact it gives me random noise/mess on screen - like suddenly appearing horizontal bars and such. They are not solid bars that are on screen entire time. Any suggestion will be appreciated.

    Potential game ports for B&W Macs

    120v Mac 512k plugged into 220v current

    hi,  I am bidding on US version of the 512k sold here in Europe as "untested", "condition unknown". There's probability someone tried to power it on without any proper step up/down transformer.  What could get fried besides analogue board? I am hesitating if it's worth buying for parts. Any...
