I look forward to the Pico 2 and related boards. All those improvements on the Pico 2 will cost you a whopping $1 over the price of the original Pico...

i would install a PC emulator on your Mac. Insert the disk and confirm you can read the directory and copy files from your emulated PC. If you have a PowerPC Mac, you can install Virtual PC (old commercial software). If you have an Intel Mac or newer, you can install the free PC emulators...

A Class 2 card is very slow according to https://en.wikipedia.org/wiki/SD_card You should use a Class 10 card or faster. SanDisk Ultra or Extreme are good choices. You should be able to buy a SanDisk 32 GB Ultra or Extreme for $10.

Great job. I see the problem IC had a leaking capacitor on both ends. The old cap juice is nearly invisible, and takes some effort to remove completely.

Well there is ZuluSCSI, that lets you move files via USB… I don’t want to start a war - I own both.

BlueSCSI has a transfer utility. This utility allows you to transfer files from your SD card to and from your Mac. Create a folder on the root of the SD card called shared Use your modern computer and place files in the shared folder of your SD card. You can try this with files downloaded...

Interesting. Seems similar to the ESP32 Softcard that was recently released https://www.tindie.com/products/cvt/esp32-softcard-expansion-card-for-the-apple-ii/?pt=ac_prod_search

Looks like FWB CD-ROM ToolKit 4.0 is what you need.

Nice - I saw the video yesterday. Any thought about adding mounting points for a FDHD?

I’d bet the drive will work if you install CDRom Toolkit compatible with MacOS 8.1

The Roland SC88ST has a Mac Serial port on it, as does the Yamaha TG100, MU50 and other MIDI devices of the era. Why are you using the Pocket MAC interface?

Very Nice

Ok, thanks for the quick update. I‘m happy the chip can be programmed with the PICKIT 3 - so I don’t need to invest in a new programmer. Great project - will definitely build one, as I only have one Gravis Gamepad and it’s held up well thru the years.

I viewed the GitHub, and the main page lists the PIC12F1501, while the BOM listed on the PCB page lists the PIC12F1840. Which one is correct? Can the chip be programmed with a PICKIT 3?

Many Quantum drives fail because they used some type of rubber to rest the head against when the drive powers down. The rubber has turned sticky over time, holding the head in place. in my experience, Syquest 44 MB drives hold up much longer than most drives If want the real hard drive experience.

Old Quantum hard drives frequently fail, sitting in a computer that’s been unused for decades.

StuffIt Expander 3.5 seems more appropriate on a SE/30, and it works on up to System 7.6 Macintoshrepository Note the StuffIt file format changed with version 4

Since your HD is dead, you should replace it with a ZuluSCSI or a BlueSCSI Device. Install a bootable drive image on your SD card, plug it into your device and your all set.
