    Trying to identify a game from memory

    there was a game I used to play when I was a kid, but I don't remember what it was called.  I remember being inside a scene with a bar, and getting asked the question: "Choose your poison"  Trouble was, I never could get past that level because I kept typing out actual poisons which of course...

I pulled the PRAM battery as it was showing signs of starting to leak. this was years ago.  I just so happened to pull it out today to recharge the battery, and check it out...

    I would hate to write one if I dont have to, but is there a quicky little tool somewhere that can take the LOW/HIGH images of ROM and interleave them back into a single ROM image? I vaguely recall a thread about that but ill be darned if I can find it.

    Testing CRTs

    For the heck of it, I decided to test a compact mac CRT, a 12ATY4N from I think an SE or maybe a Plus.  it had SEVERE burn-in and I kept it around just in case. So for giggles I decided to pull out my Sencore CR161 and test the tube.  Once I realized it was a 12V tube and not a 6V tube, I got...

    Macintosh Plus FDHD

    I have been rolling around with this idea in my head for a long time. I think its time to get it on paper though. BMOW is discontinuing the rominator for the plus so thats what sparked this thread.  He made one more run so I bought one.  So, as the title says, I was going to transplant a SWIM...

    SE/30 video issue that has ME stumped!

    I have an SE/30 motherboard here that belongs to someone else.  It had a strange issue. it had black lines jumping around coming and going. UE8 was already changed and some other ICs swapped around by someone else.  All the PALS are soldered in place, NO sockets! which that sucked.  So, I...

    I have a 5400/6400 180.  I did a fresh install of 7.6, and it has an apple ethernet CS II card in it.  Soon as it gets done on the install, it reboots, I go to TCP/IP and it complains saying "Ethernet" is no longer available, and it only gives me the 2 serial ports.  Odd, so I tried another...

    I have a Macintosh IIx I rebuilt a little over a year and a half ago. maybe 2 years.  I was prepping it to get rid of it, and noticed the batteries were flat.  So I was wondering if anyone has replaced the PRAM batts and how long they got out of them sitting around?

    AppleVision 1710AV: How many around?

    I just picked up an applevision 1710av that came with an 8500/150. Thought the monitor was cool so I grabbed it fairly cheap locally.  Anyways.. The monitor works very well surprisingly although it does have a cool turn-off spot. However, a quick google search shows that these things were...
