Today's fun has been organising hedge cutting at my Dad's house form 300 miles away at short notice. Yesterday I had a decorator visit the house and give a quotation for external redecoration and he gave an offer to start today, which I jumped at. This morning he texted me saying that to get to one...

Yout have got a 74LS76 and not a 74LS76A haven't you? The truth tables are quite different and with an A variant the K and J values are ignored by the second stage. Screenshot_20240416_121850.jpeg P.S. Putting a logic analyser onto U64 pins 6, 7, 8, 9 and 11 would be useful as the relative timing o...

Screenshot_20240416_121850.jpeg Hmm, it was actually an 74LSAN, I have swapped for a 7476 and no different. Will see if I have another...

OK, back to cassette interface again. This is the schematic for the cassette out: Screenshot 2024-04-16 at 10.52.00.png What I know so far is as follows: U64 pins 2,4 and 16 are receiving the data that is to be saved to cassette as expected. U64 pins 1 & 6 are getting a clock signal of 4.8Khz U6...

OK then. This just arrived in the post: IMG20240415094431.jpg IMG20240415094425.jpg The weird thing is, I didn't order it, and whilst I can pretty much guess what it is, since it fits my Evercade, I have no idea where it came from, or what files it will accept. Weird. I suppose I need to go and look...

As a few others have suggested, HDDRIVER or PPERAs driver allow for byteswapping so you can just move the SD cards between the ST and PC in order to transfer files. My interpretation of the question is that you want to move files to a disk that may not have HDDRIVER installed but ICD, and you don't ...

The Mac Portable regulated power supply unit is complete. I designed and printed a box for the electronics (everything hot glued) and it all tests good. IMG_3674.jpeg The built-in ammeter is useful as it shows when the system is charging the battery and when it reduces the CPU clock too. When suspe...

True.

Doesn't it need USB C to charge properly though? IIRC it takes 15v when charging.

I have no idea and have another switch anyway

Okey Dokey

@rubber_jonnie I think they had dropped it with the USB plug in and it landed right onto it. It did have the screws too but obviously that didn't help. I still have it and guess I should get round to putting a 5V power supply plug on it at some point :D True. Doesn't it need USB C to charge properl...
