A few years ago I made a Sorcerer tape simulator from an Arduino:

Too bad Teensy 3.5 is no longer available and Teensy 4 is not tolerant of Sorcerer's 5V signals. Another 5V Arduino with SD card shield should do the job. The first version of Tape Sim was on an Arduino Mega:

Hi Claus!,

Yep, i remember it, it's a cool device despite the damn teensys. Why they're so expensive?.

Now there're nice alternatives much powerful than the 3.5, something like the RP2040 based dev boards.

Thanks!

It's debatable whether RP2040 is 5V tolerant. Anyway the Tape Sim is not a demanding application, so the older 5V Arduino boards (with a 2nd serial port) can handle it.

I've got it working, it would be nice to port it though

Am porting this now to the 5V Arduino Micro. The FrequencyTimer2 lib doesn't support that board so I switched to the FrequencyGenerator lib, modified to output on pin 10. Successfully loaded TRMLD into the Sorcerer.

Got a SparkFun microSD board coming soon, so will try to integrate that next.

Ported!

Got spoiled by the Teensy's vast resources. Had to rewrite a lot to fit within the Micro's 2.5K RAM.

Now also ported to SparkFun Pro Micro 5V 16 MHz, attached to SparkFun Level Shifting microSD board.
