Hot on the heels of the HD68 to 50 adapter is this HD50 to 50 adapter. Super low stock availability, these connectors are a mess to get ahold of. Also, the Mac Portable to BlueSCSI adapter is now restocked including for 2023_10a. https://androda.work/product/hd50-to-desktop-50-pin-scsi-adapter/

Correct, this does not make BlueSCSI into a proper wide SCSI device. Just makes it possible to more easily use on a 16 bit bus.

Did the screen cable replacement function? I'm not going to be any help on the hinge issue, mostly curious if the display works.

New product: The HD68 to Desktop 50 Adapter. Plugs straight into a BlueSCSI or other 50 pin internal Desktop drive and connects to the HD68 bus. Includes a high-byte terminator for situations where that matters. Low stock availability, these connectors are expensive and I don't want to order...

Agreed. @MICHAENTOSH please create a debugging thread for this sad mac issue over in the Mac Portable Subforum. Based on the picture, those are the original capacitors. Even if they did not visibly create a pool of fluid on the motherboard, they can fail invisibly or cause corrosion directly...

It could be related. There are leaking capacitors in the 12v generator circuit, and I believe both the original hard drive and floppy drive require 12 volts. Might only be able to power one at a time with the leakage. Low or improper capacitance on the boost driver (boosting from battery...

That's a huge problem for Portables. I suggest that you don't run any more power through the system until the capacitors have been replaced and all the leaked capacitor fluid damage has been repaired. The leaking electrolyte causes tons of problems, everything from primary voltage regulator...

Is he saying that there is no sad mac error code without the battery eliminator installed, and getting a sad mac error with the battery eliminator installed? According to the Sad Mac Error Codes reference, that's a memory error saying all 16 bits are not responding properly. But there are no...

The ferrite bead mostly helps with interference. I would reinstall it, just wrap the outside closed with electrical tape.

It's out of stock for the 2023.10a version, but kits for 2023.09a and earlier are available. No specific ETA, I just need to print brackets and put things together. The M5126 Backlit Portable actually doesn't have a Hybrid Module. Instead, Apple directly embedded the power regulation...

1: I haven't received feedback about which Portable versions the Battery Eliminator has been used in. To my knowledge the Backlit's Modem slot is the same as the original M5120 so there should be no electrical difference between them. 2: The PCB does contain a provision for a 9v battery holder...

There's one additional thing you could try, which is voltage injection and the "owee" check. Step 1: Use a current-limited supply and inject about an amp of current Step 2: Touch stuff until you find something really hot (hence owee) Alternately, do the current injection and use a thermal...

SCSi adapter with blinkenlights is back in stock. Sorry for the delay, didn't notice the "out of stock" notification.

Parts and boards are now ordered so I can make more of the Battery Eliminator. And a hopefully-production PCB for HIDHopper ADB.

I'm not an expert on the 170. But a short should be causing a lot of heat to be generated by the component which failed. Could be a chip, a capacitor, a mosfet, a resistor, tons of possibilities.

I'm pretty sure it should drop the output voltage when the current limit is reached. If it's dropping to 1.1v then either the adapter is bad or there's actually a short and it's protecting the system.

The Mac Portable Battery Eliminator is available now, assembled only, in low quantity. HIDHopper for ADB will hopefully be next, just needed to update the PCBs a bit to handle part clearances. So those PCBs will be ordered soon and then it's a matter of designing printable cases.

Assuming your power adapter actually has a 1.5 amp current limiter that works properly, you'll be fine. The 1.5 amp current limit is for a few reasons: The original lead acid battery charge current was not allowed to exceed 1.5 amps Apple's battery charge circuitry might not be able to...

Hardware and Project Updates: BlueSCSI Desktop Hardware: The updated and more affordable BlueSCSI Desktop 50 Pin design has passed my local testing on a PowerMac 7300, Beige G3, and Mac Portable. It removes the microSD slot and USB-C power connector, but in doing so also cuts the cost enough...
