Question about the Macintosh Portable

[Froggy814]

Alright! Thanks! I found JMC's video and he had the list for the floppy drive, And I found that to have an external scsi, you need a diode from 5v to one of the pins, TheTechKnight explains that but I found that out because of JMC. Is that correct?

I found out that the dip switches are for rom association. Thanks to this site, It hasn't been updated for 10 years so I downloaded it with httrack!

Welp, all of my stuff for the computer showed up. Thankfully Joes computer museum was kind enough to add a hybrid module after I had ordered. But Its all here, The battery eliminator and the bluescsi with the hybrid module. Just finished soldering them together. Now, just waiting for caps to tear the portable down again!

 

[Froggy814]

Does anyone have a detailed video or description on how to install a hybrid module? Thanks!
P.S. My caps are arriving on the 16th! (I hope)

 

[Froggy814]

All of my capacitors arrived! w00t, Now to install them! I will update if al goes bad, or smoothly!

Good luck!

Thanks! A lot of pads lifted Now I have to trace traces... Fun!

It works, 4 bodge wires (one on the hybrid pins and 3 on the caps), a couple of trace soldering and viola! It fired right up with a new hybrid module and caps with a new usb-c power supply I made and a battery eliminator... It showed that there was no hard drive connected with only like 6 pixels dead! I cant believe it fired up first try.

Thanks to @3lectr1cPPC @finkmac @joevt @SuperSVGA @pl212 and @Juror22 for helping me make this portable alive again.
I will share it starting up when I can. Thanks soooooooooooooo Much!

@3lectr1cPPC You might want to put down on your website that their are some caps on the ball mouse as well

Can someone tell me what's wrong? I insert my Sd card that has the ini file and hda file into the bluescsi and I plug the bluescsi into the portable but the power light only turns on when the external power bridger is in place and the act light never lights up. Also there is no log file on the sd card.
Thanks!

So glad to hear you've got it running! I can't offer any advice on the bluescsi but I'm sure someone else here can. Great work.

Let me know what the cap values on the trackball are and I'll add them to my site.

 

[Froggy814]

Alright! If you have a portable you'll want to replace them one of them was fine the other had the tell tale electrolytic burning sound.

Caps And Values - 16v 10uF Radial 4mmx8mm
and 50v 1uF Radial 4mmx6mm

There's your values @3lectr1cPPC
I'm glad I was able to get the portable working, And I figured out one problem of the bluescsi, the latest .uf2 for the pico doesn't work, unfortunately I still cant get it to boot.

 

[Froggy814]

Here is my latest log.txt remove the .zips and those are my files i am using. I found that the latest bluescsi pico update doesn't log or flash lights so I downgraded, The .ini is my homemade ini trying to get the portable to boot.
