macsonny Posted September 19, 2023 Share Posted September 19, 2023 Interesting little find today. I purchased a "not working" 1050 drive on the weekend that just arrived. I haven't powered it up as the sticker on the top said "Drive doesn't sting" and "Drive not recognised". Opened it up and once removing the EMI shielding saw a large circuit card floating about. It wasn't connected to the main board. Inspection suggests it's a Happy mod but wanted to get some opinions. There is also a mod board on the front panel with a few LEDs and switch per attached photos. I've re-seated the mod board and will test later tonight but wondering what others think this is?

Confirmed for myself it's a Happy mod and reead/write control board. Very cool! Quote Link to comment Share on other sites More sharing options...
macsonny Posted September 19, 2023 Author Share Posted September 19, 2023 Photos of the remote controller board if anyone is interested plus wiring locations on main 1050 board. 2 Quote Link to comment Share on other sites More sharing options...
macsonny Posted September 19, 2023 Author Share Posted September 19, 2023 In the last photo there is a switch missing. I think it's the fast/slow switch for the Happy upgrade. Anyone know the wiring for this function so I can replace the switch and have the fast/slow mode option? Quote Link to comment Share on other sites More sharing options...

It is an original Happy PCB, but pretty sure the controller PCB is third party, I have 3 original Happy 1050 PCBs complete with controller.

ijor Posted September 19, 2023 Share Posted September 19, 2023 I agree it is an original Happy, and it's an old one with 6K RAM. The small PCB, which of course, is not original, doesn't seem to be a Happy controller clone. The original Happy controller has two switches and a single led, and plugs in the small 5-pin connector.
