I recently found the Radio Shack TRS-80 computer that Egon uses. I was wondering if anyone has, or knows where to find, the cassette interface backing.
Fingers crossed.
I have one. I don’t have a recent pic of it, but here’s a shot I took in 2014.
I got the PC-4 calculator first, and searched in vain for the interface by itself. I finally saw an auction on eBay with the PC-4 AND the interface, so I bought the PC-4 a second time just because it was so hard to find the interface.
Here’s the Equipment page for the item(s): https://www.gbfans.com/equipment/other/radio-shack-pc-4-calculator/
It IS possible to build an interface from scratch, as odd as it may sound. I can’t find the thread at the moment, and the photo links might be dead even when I do, but sometime prior to 2014, James Fincher of Fincher Technologies (username jimfin on this forum) used some Facebook photos of mine and a couple of measurements that I provided to make one entirely by hand.
He sourced the exact power button, even had the correct number of pins on the interior to go into the PC-4. I held the thing in my hands before he told me it was hand-made, and I couldn’t tell the difference between that one and my factory-made one. I even asked him where he found another real one, then my jaw dropped when he said it was custom-built.

Wow thanks for the information it sounds like an uphill battle to either find or recreate. If you ever find another or if anyone knows of one, I’d love a shot at it. Thanks
Hey Don, I just discovered that Ryan the Mast has a 3D printable version of the interface on his Thingiverse account.
If it’s as good as his parts for Egon’s stethoscope, it will work awesome for your needs.
