It’s not a standard port, but I’m pretty sure it’s in the same family as the AAUI connector that Apple used for Ethernet on some machines. I think it’s a 26 pin MDR series connector, but I’m not sure. One of these days I want to buzz out my cable and see if I can figure out the connector and pin...

It does indeed - headphone and line out jacks on the side, volume control, and front panel playback controls. I haven’t tried it, but it seems like there’s a good chance it’ll respond to standard Sony remote commands. Also - I forgot, it has a bay on the side for a removable, rechargeable...

Yep, they had a number of models. Searching eBay for “sony prd” returns quite a few results. One thing you give up is that they use an external AA battery pack instead of having internal room for the batteries. Mine came with one, but I use it with a generic adjustable power supply from Amazon...

Love the PowerCD. I wish I had one for my collection, but they tend to turn up on eBay for much higher prices than I want to pay, or they’re missing the dock (or both). I picked up a Sony CD-ROM Discman a while back, which I think goes well with my Duo setup.

This whole thread is amazing! I knew things like this were possible on classic Macs, but it’s fun seeing it in practice. Great work, and keep the updates coming!

Brilliant! I’m looking forward to seeing how you make out on resolving the brightness control.

I recently put one of the cheap Amazon adapters and mSATA SSDs into a 12” PowerBook G4 and it seemed to work well. I haven’t used it much other than a fresh restore of the stock software, so I can’t vouch for the long term stability (or how it would work on other IDE machines of the era). CY...

Glad you found it and got the IIci working!

These old Ethernet cards are almost exclusively 10 Mbps (megabits per second), which is 1.25 MegaBytes per second (MB/s) - so yes, capping out around 1 megabyte is about right, once overhead is taken into account. Edit: Plus the network stack and drivers on classic Mac OS are notoriously slow...

It should boot from the floppy as the highest priority if the disk is in the drive at startup. Assuming it boots successfully from the floppy, you should be able to just copy the Enabler from the floppy to the hard drive. It’ll be in the System Folder on the floppy.

FWIW, a “Q” reference designator is usually a transistor, not a diode. Hopefully the part markings that volvo242gt provided will help.

Glad to see you got it all working! I like the way you walk through and explain things, and methodically explain what you’re doing. Good stuff! 👍

I don’t know what’s on the card, but I could read that as NVRAM on the card itself, rather than the system PRAM. If that’s the case, I have no idea how you would go about resetting it. It looks like there might be a EEPROM or SPI flash installed at U3, so maybe reflashing the firmware would...

Great looking setup!

For some reason the link got mangled, it should be: https://www.rabbitholecomputing.com/retro-sata-pci-hard-card-newsletter

Here’s the pin out of the SE/30 PDS slot, if that helps.

Thanks @Phipli, that’s a better explanation of how it works. I hadn’t considered the “parse the partition table at the beginning of the card” scenario. That makes sense.

Correct, for the S2SD the drive parameters are stored on the S2SD itself, while the actual drive data is stored on the SD card. I’d probably recommend that you put a suitable SD card in, configure it, and just leave it rather than swapping around. The SD cards also just contain the raw drive...

Great video! You did a great job explaining everything, and I’m impressed how far you got given that you’re new to these old Macs. I’m looking forward to seeing Part 2!
