    Well it used to work: 128k woes

    New ROMS installed and all is well. Boots and runs fine. Floppy Emu has a version of system 1! Fun times. My first Macintosh experience was in 1985 on a similar machine at work. It was an astounding revelation, and this brings all those memories back.

    That's interesting info, but I'm afraid it's above my pay grade to implement. I do have a set of ROMS on the way from ebay.

    I've scrubbed the pins, they were tarnished a lot. Still no go. In good news I got the 400k drive working! I bought a NOS felt pad for the drive off ebay, installed it, and now it works well. The old pad was almost totally gone.

    Switched F6 and F7, installed my Plus ROMS and it booted. Put the original ROMS back in and the same problem. Tried it a couple more times and it seems that I've got bad original ROM or ROMS.

    I'll give that a try.

    I just have a multimeter, will that work to test the caps?

    Hmm, would it boot if I remove F6?

    Oh yeah, one capacitor was backwards. I fixed that. Still the same.

    More troubleshooting: Swapped in the ROM chips from a working Mac Plus. Got the error code 02002

    Well it used to work: 128k woes

    Hi everyone. So my recently acquired 128k with the 512k socketed upgrade won't boot now. I had the caps replaced and upon return I get no bong on power up and a screen of vertical lines. Installed a Plus logic board and it boots fine. So far I've reseated all the RAM chips. Cleaned the ROM...

    What is this in my 128k?

    Yes, I get the crossed out icon when the disk ejects. What's the scoop on the pressure pads that I hear about?

    What is this in my 128k?

    I'd like to keep the 400k floppy but I don't know anything about fixing them. It accepts the disk, makes some noise, then ejects it smartly.

    What is this in my 128k?

    Managed to get it to boot all the way tonight. Swapped in an 800k floppy since the 400k won't read disks. Using the yellow stripe ribbon cable it worked. Confirmed it's got 512k of RAM. Oddly, while it will read the double sided disks it crashes a lot when trying to access it.

    What is this in my 128k?

    A place I worked in 85' had a fresh made Fat Mac which was my intro to the Macintosh Way. Everything I'd used before suddenly seemed like the dark ages. How much would this upgrade have cost back in 85'?

    What is this in my 128k?

    Here's the whole enchilada. It boots up nicely, no screen issues or burn in. The floppy won't read a disc, no surprise there. Dated in late October of 84 on the case. Who would have installed such a memory upgrade, owner, dealer?
