    BlueSCSI on Macintosh Portable

    So is everyone seeing the same two issues I am and with two different ram cards? A) slower performance overal B) even slower performance after waking from sleep BTW that is awesome you have a logic analyzer for System 6 ?

    Any IICX chip level repair experts? I've got a clock but RESET / ARST is stuck high

    Hey Kai I have been watching the livestream on YouTube you were in on mac84s channel and my iicx had the exact same issue. I have clocks and reset but no activity. You mentioned removing a jumper somewhere and walking the bus. I’d like to try that but I don’t know what jumper. Also what docs are...

    Macintosh Portable Battery Adapter

    It went well. Yeah lots of support material inside but I needed to test my new replacement printer out anyway and I have support pla which is really nice. It falls right off the part.

    Macintosh Portable Battery Adapter

    There’s a replica stl of the original battery pack online. It’s very acurate. I think it’s a 3d scan. I used it to make my battery. I cut some strips of copper sheet and made some 3d printed fasteners to lock them into place. Worked perfect but I’m not sure how well the copper pads wil hold up...

    Copying legacy software from internet repositories to 68k Macs

    I have a floppy EMU (and a BlueSCSI in the portable but not required). my process is on the MacBook Pro I download my disk images from Macintosh garden and extract them. I then use either miniVmac or Basilisk ii to mount the disk images onto the desktop and I mount the sd card disk from the...

    Awesome. I’m curious how / what is going on…

    BlueSCSI on Macintosh Portable

    So to sum up this thread: • BlueSCSI needs external power from floppy cable in order to wake it up after sleep. • RAM expansion cuts CPU speed in half and then chops that speed in half again after sleep. * could still be isolated case to a defect in my board. Won’t know for sure until someone...

    BlueSCSI on Macintosh Portable

    I found the culprit! It's the 7MB RAM expansion. I pulled the card out and bam! my machine was running at full speed (even faster than yours at 2.154) before and after sleep. Both issues fixed with RAM card removed.

    So do I. Max performace. I just tried system 7. Same results. I get faster graphics and HD speed than yours but your cpu and math are faster…

    BlueSCSI on Macintosh Portable

    Wierd. A lot better. Your cpu shows 2.1. I ran the cpu test only. You are also running system 7 which slows things down and I was on system 6. 🤔

    Any IICX chip level repair experts? I've got a clock but RESET / ARST is stuck high

    I don’t even have a display or anything hooked up. Not even a speaker. I’m only trying to get anything other than a clock right now. Some square waves off the roms mpu etc. For that I shouldn’t need any RAM installed right?

    BlueSCSI on Macintosh Portable

    Right. Like a lipo. I assume when the portable does its final shutdown the battery will not be lower than 50%. I’ll check it next time.

    Any IICX chip level repair experts? I've got a clock but RESET / ARST is stuck high

    I don’t need to have the memory sims installed either in order for the system to run correct?

    Any IICX chip level repair experts? I've got a clock but RESET / ARST is stuck high

    Right. I figured it wouldn’t affect the system as a whole. I ordered some crystals. I know it’s a resonator and not an oscillator. The ones I ordered call them both but I’m pretty sure it’s just a crystal. There was a broken trace but after I fixed it it still wasn’t oscillating. This is what I...

    Oh wow I didn’t realize you can’t fully discharge the lead acids. Yikes I probably came close a couple times when I was testing it.

    Any IICX chip level repair experts? I've got a clock but RESET / ARST is stuck high

    OK Here are my new findings: For starters I have no oscillation on Y4 or at Um5 pin 2 and 3 as well. they are sitting at 2.4v Not sure if this is important or not. Is this just the realtime clock or is it part of the VIA chips and are they required to get the MPU running? On the MPU: Reset...
