#4786 — ZX Spectrum +3 power up after 30 years

Connected a ZX Spectrum +3's RGB to a RGB-to-SCART converter, and then 
connected the SCART to a SCART-to-HDMI converter. Feeding the HDMI to a 
ATSC television and using a 110-to-220V AC converter for the power brick 
worked; a ZX Spectrum +3 is on the air in Maryland, USA. If I remember 
right, I had last fired it up in 1989 in a 220V AC PAL country.

I am wondering if it is possible to have something like a Raspberry Pi's 
headphone socket play back .TAP or .TZX files into the +3 so that the +3 
thinks it is hearing from a tape recorder. I am sure it has been done; 
would be grateful for pointers (and maybe even a MicroSD RPi image) 
towards a short-cut to save me trouble.

Thanks,

Supratim Sanyal

Now try this with any year 2000 PC or notebook.

https://retrocomputing.stackexchange.com/questions/773/loading-zx-spectrum-tape-audio-in-a-post-cassette-world
might help you. Consider buying a DivIDE interface:
https://divide.speccy.cz. It is supposed to work with all Spectrum
generations. No more tapes or diskettes.

Greets,

It's very possible - I did some research and followed the footsteps of 
others, and have a great Raspberry Pi ZX Spectrum Cassette Player that 
has no issues with fast loaders even at 212% of normal cassette loading 
speed (e.g. Falcon Patrol II). I wrote it all up at 
https://supratim-sanyal.blogspot.com/2020/01/zx-spectrum-tzx-tap-zip-cassette-loader.html 
if someone wants to try it.

Thanks,
