That is so awesome! The digital tuner is extremely useful. I think the only thing I wish I could do with it is bung in the tuning hex code instead of seeking or loading from disk. But that is a minor niggle and it works really well :)
Also, that may be your sole contribution, but I suspect that work is the majority of the diff from Acorn's ATS. That and switching the I/O to I2C via the user port.
I like what they have done with the NEXT, but unfortunately I have no nostalgia for ZX Spectrums, I grew up in a BBC Micro household. I do have a +2 in my collection here, but I rarely use it.
It does, the first part of my post shows this on the TV. But for the BBC Micro I'd need to physically hack the Morley quite a bit to take composite input. I also have an Acorn Teletext Adapter, this can easily take composite instead of RF via a jumper.
The modern version (W65C02S) is not 100% pin compatible. It would be very obvious very quickly if that had been done. There isn't another modern equivalent with the same pinout that I'm aware of.
Yes, there are many original 6502s around, and they are probably worth half of an R65C02, or even less.
Oh, absolutely, but it is usually way more expensive than buying a load of chips in the chance you'll get a genuine one.
I work on a project called PiStorm that replaces the 68000 series of CPUs using a small FPGA for bus translation and a Raspberry Pi.
I once ordered a large batch of 64pin DIP sockets from a Chinese site and received a piece of ladies' undergarment instead. It took a long time to get my money back from that transaction.
I do know the supplier I bought them from bought them in the hundreds. I also know I'm the first customer who has noticed they are counterfeit.
So, there is still enough money there I guess.
New / old stock? I have a supplier called TV SAT in Poland who is pretty reliable. I've had pretty good success with UTSource. But it really depends on what you are looking for. Usually it is a case of looking at reviews and crossing your fingers.
I've been wanting to squeeze that ARM fact in one of my Archimedes blog posts, but somehow never got around to it. It is pretty cool how it was developed.
Yea, I tried a couple of AIs on it whilst writing that post and didn't get anywhere. It does look like elsewhere in the comments here people have maybe figured it out though.
It was not littlediode this time, I'm not going to name them (you'll be able to tell with a search as the chip has the same date code on their auction). There are several out there that buy from China and resell. The good ones at least run a barrage of tests first.
I am puzzled by that too, it is roughly where the VIC II is and it doesn't appear that anything was soldered to it to tap it. My other guess was that this sat on top of something and the hole was needed so it would sit properly?
