I’m going to guess 5V, because there’s no regulator.. I love small cases like this, because you can put a SCSI2SD in there, and power it from the SCSI buss.... As a matter of fact, if ya decide you don’t want it, lemme know what you’d want for it.

Fantastic. Where can I get one?

I’ve heard both are ok, but wondering if anyone knows advantages of one over the other... While checking my bag of cables, I found both, and it made me wonder..

A couple years ago I put a mSATA SSD in my G4 mini, running 9.2.2 V8, and today I thought maybe I could speed it up by using the FireWire bus, rather than the internal ATA 100.. . I already have the mSATA to SATA adaptor, and would just need to get a SATA to FireWire case. Anybody have any...

Sorry if I left you hanging..... J1 is the connector from the deflection coil on the CRT to the analog board.  There are 4 wires, I think I remember that they’ll be red, blue, green, yellow. I don’t remember the order.  Check the solder joints on the analog board at that connector, and check...

After a recap, I got the chime back, but still have screen issues.  Checked the electromotive force, and I’m reading 13.51 and 4.47... and drifting lower & higher Both are too far out of spec., and I’m asking for help on finding out where I should start with this one.  Edit When reading...

@BadGoldEagle  I thought the glass things were diodes, like this one https://www.digikey.com/product-detail/en/microsemi-corporation/1N4110-1/1N4110-1-ND/4898967 i also tried to figure out exactly what it is, model, rating, etc, but got no response. 

I looked at my options, and bought a 128GB mSATA drive, and ATA adapter, for a combined total + shipping = $22.38, and replaced the 80GB spinning platters in an A1103 1.5Ghz, 1GB, and now 120GB storage. I split the drive into 2 partitions an put OS 9 and 10 on there. I think I’ll take OS 10...

Before I put it away, I thought I’d post a picture of my SCSI adapter with disk mode switch, for those that haven’t seen one.  Switch off, it allows for attaching a external disk. Switch on, it turn the PB into a SCSI disk, for backup / syncing with home / office computer.  The ones without a...

  @Iesca  Here’s the pictures of my toasted PSU, and my slapdash connection of the old PowerBook cable to the new IBM PSU.  Essentially, Red and Orange to +16V,  and Blue, Black and Shield, to Ground. 

some of the joints I had on my 512kE These are VERY bad. Make sure to use a very hot solder iron, to get a good flow and don't dwell on the joint too long, or you'll lift the trace, and use some good flux

It’s on at least 12 hrs. everyday.  I assume it was micro arcing, which leads to carbon, which leads to more arcing, more carbon, more arcing....... It’s not dirt buildup, the interior is spotless.. As a matter of fact, it’s on now..

I re flowed the joints 3 years ago, and changed C1 to a 3.9uf 250v metalized polyester last year, and this year I get this...

Does anyone know what causes this, and what will fix it? I pulled it out of storage and wired up a new PSU (IBM 16v 4.5A), and was disappointed to see these lines.  The top half was worse, but after squeezing the top edge, it became better than the bottom half.   Next, see if I can rebuild...

I opened the MFS in an emulator, and saw this. It's only 361k I wonder what "Electric Start" means.....
