They have 3D printers at the school I work at. It's pretty cheap to print. For example, I printed a case for my iPhone, it cost $0.55. I'm not sure if there is a 3D scanner there,…

I don't know if they ever made one specifically, but there were adapters out there.  I think our own member bbraun has/makes an adapter to connect ADB to pre-ADB Macs.

Did Kensington ever make a trackball for the Mac 128k/512k/Plus? I much prefer trackballs to mice with my classic Macs and have a couple ADB models for use with my SE/30's and even…

You try another known good working drive? I would hope so.  Otherwise, did you check the DMA lines that bounce between the SCSI IC, GLU, and VIA? 

I checked all traces going to/coming from the SCSI IC, they are fine.

Another question I have is around how to burn CDs such that they can be read by the LC 520.   I tried burning one on my Mac Book Pro but I keep getting a disk not initialized error…

I would never ship an LC5XX variant in the same box.  I would remove the CRT and front bezel, ship it separately. 

Time to check traces between the SCSI IC and the SCSI header. They break at the IC. 

The voltages above were the ones coming from the pwr supply. With the RAM they are -5V (6), -11.77V (7), +5.04V (12,13), +12.71V (14) Molex are 12.33V and 5.05V RAM was maybe ju…

so -12 is too low and +12 is two high,  and what are they without the ram?

ATX connector measured voltages are -4.98V (6), -10.47V (7), +5.28V (12,13), +12.62V (14) Molex disk connector voltages are 12.71V and 5.08V

With symptoms like that how is voltage?

Yep! Straight into the bootable floppies blessed System folders and they are good to boot off... then just copy into your 520's System Folder on it's hard drive and restart and it …

This one is a little bigger and you kinda have to squeeze it in the holding area but you can get it in there... at least with this you can replace the battery's when need be... Thi…

Not a bad idea. I'm still using the original pack on mine but I'm sure it will die one day.

Ok so I found a great solution to replace the battery..... Purchase these http://www.ebay.com/itm/180979418921?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT …

I would not trust shipping one at this point. That being said, at least one is in Australia. A member here has it.

Unfortunately it will be 575's  only for me in the forseeable future... Unless I take a trip to the states. lol

The man's got some taste

I'll be back. I just have to... go and do... a thing. Over here. yes...

Awesome man , Did you get MLCC's on there or stock Panasonic electrolytics? I forgot. I'm sure blob would be happy! I think he just turned 71

Alright. I'm going to order up a set then, it should really help when this thing decides to give me trouble in the future.
