Happy 1050 Controller Switch Position Sticker

I'm not sure if this will be any use to anyone but attached is a jpeg image of the sticker that shows the various positions for the Happy Controller toggle switches. The sticker on the top of my Happy enhanced 1050 had seen much better days. So, I scanned it and did my best to tidy up the image and ensure it is exactly the same size as the original sticker. It looks fine printed by inkjet as a trial, so for the finished article I'm going to (laser) print it on to glossy self adhesive paper like the original.

Here are some pictures of the original 1050 Happy Enhancement and Happy Controller. The logic ICs on the Controller are DM74LS00 (Quad 2-Input NAND Gate) and 74LS74APC (Dual D-Type Flip Flop). J11 plugs into the Controller. 4 Outputs on the Controller adjacent to the DM74LS00 (L to R: Grey, Red, Red, Red) go to the J11 pins on the 1050 board and appear to control read/write operations via a three position switch (Always Write/Always Protect/Normal Operation) and 5 outputs adjacent to the 74LS74APC (L to R, Grey, Red, Red, Red, Red) go to the Happy Enhancement and appear to control the Fast/Slow modes via a two position switch.

 

I hope this post is helpful. I would imagine it would be easy for someone with the time/knowledge to produce an exact clone of the Controller, but I wonder if it would be possible to produce a version that works with the more recent Atarimax (clone) Happy Enhancements? Also, is anyone able to post a scan of the original Controller installation instructions (not the Happy Enhancement installation instructions or Revision 7 Software Instructions, which are available)?

Can the Happy be operated without the switches? I have a drive that has the board installed but no switches, and it powers up but isn't recognized by my computers, and the motor doesn't run.

 

And nice pictures! Useful in that I was wondering what the connector was for on the main board. Happy is new to me.

You mean the Happy main board without the Happy Controller board? Yes, of course, it was optional.

 

If the motor doesn't spin at all when you turn on the drive something is wrong. Could be several things. Search the forum for 1050 troubleshooting.
