6128 Plus Tape Modification

[tibbs1972]

Hi all,

I just spent a few hours adding the Tape mod to my 6128 PLUS.

Thankfully I didn't blow it up.

I used a 5VDC SPDT Relay for the remote control, and added an 8 way pin header to the main PCB.
The Relay is hot glued to the base of the 6128 PLUS and i put a general purposed Diode across the Relay Coil to protect the Transistor from feedback.

For the Transistor, I found a NPN Transistor on Amazon that doesn't need the legs crossing and matches the PCB. (see PDF).

So far, the 6128PLUS starts and pauses my old Data Recorder and Loaded "OH MUMMY".
I also managed to save a "HELLO" basic file to Tape.

I made a CAD drawing of the mod and attached a PDF copy for reference. see attached.
