What SD CARD should I buy?

If you want an SD Card for your camera - these are the ones I use and recommend. 

I'd strongly recommend not to buy any SD cards off ebay - I've heard about too many issues with counterfeit cards - often sold on by unwitting resellers. My inbox regularly gets messages from people who bought a £150 camera then cheaped out and bought a £3 memory card on ebay - Then when it doesn't worth they blame the camera! It doesn't make any sense. Good memory is cheaper than it's ever been - see the links above.

A lot of HD cameras will not work properly with cards larger than 32GB (cards over 32GB are usually SDXC rather than the SDHC standard used by 32GB cards. SDXC cards use the ex-FAT system rather than FAT32 - in short they are a different standard). - so don't just buy the biggest card you can afford - read the specs in the manual to see what it accepts.

UK & US LINKS & PRICES BELOW

RECOMMENDED CARDS (for action cams - see dashcams below)

CLASS 10 UHS-1 CARDS (For HD Cameras)

 

U3 CARD (For 4K cameras)

 

 

SPECIAL DASHCAM CARDS

The SD card in a dashcam is re-written over, more frequently than in other types of cameras. Some manufacturers void their guarantee if an SD card was used in a dashcam. So, no surprise, there are special High Endurance SD cards made just for dashcams...here's some.

 

 

VERY IMPORTANT. These links take you to the product, however Amazon have three different ways of selling. There's Amazon Direct - This means that you are only dealing with Amazon themselves, then there's other sellers that use Amazon's facilities - these show as Fulfilled By Amazon and finally there's Market Place sellers that advertise on Amazon, but operate independently.  I strongly recommend that you only use the first...the Amazon Direct - Sold By Amazon option. Even if it appears that you are paying a couple of £/$ more it is more than likely you are comparing the price of a real item against the price of a fake.

To give you an idea of the extent of the fake goods problem. In a 2016 survey by Apple - 90% of the 'Apple' chargers sold through Amazon - using the other the two methods..which includes the "Fulfilled by Amazon" option -  were found to be counterfeit....90%!

MB OMNI Entertainment System: The 8-Track games machine from 1980

The Omni from Milton Bradley is a product that straddles 70s and 80s technologies. At it’s core, it’s a game, an electronic quiz machine. However if you examine the way it works, it could be described as an interactive computer that reads program data from tapes.... 8-track tapes. In the video below I demonstrate what it does and how it does it…but first I have to get it working.
   
    
   
Playing the Omni made me think about the massive success that Trivial Pursuit achieved just a few years later. I remember that game becoming big in the UK around 1984. It's almost as though the Omni was ahead of the game...but then I thought about how much Trivial Pursuit cost (I seem to remember it being £50) and how that was considered very expensive for a board game….so at $120 the Omni never really stood a chance. 
    
It was also a lot more difficult to introduce new technology in the pre-internet age. I recall seeing products in catalogues back in the day and all you got was a picture with a brief description like 'electronic game'. It was often impossible to figure out exactly what some of these things did and when you factor in their high cost it made buying these new gadgets a gamble that many weren't prepared to make. The game Merlin was an example...back then I really couldn't imagine how it was supposed to be used but now after all these years it turns out that the less easily definable products like these were often the most innovative ones.
               
For anyone interested in looking at the way the data on a cart is laid out - you can download a five minute sample of Vincent Price's Movie Quiz by clicking here. This is one of the simpler carts with just a question step and an answer step. Jeopardy and Password+ are more elaborate.

I remember seeing Videomaster star chess in the 80s. Pieces could exchange laser fire. Unfortunately you could not play chess against the computer. About this time actual pocket computer chess games arrived.
There's a write up here

Never knew such existed. Interesting to watch and the "old video" gave me a few chuckles, and once again a job well done.

@ Mr.G - I remember that one too, although I never played it. Thanks for the link
@Slivy58 - Thanks old chap.

Atari were doing something similar circa 1980 with the data recorders of their 8-bit microcomputer series. These data recorders used stereo tapes, and had the ability to route audio from the tape to the computer's standard TV output. Atari's own vast library of educational software made extensive use of cassette audio tricks.

If it isn't too much trouble could your look on the box and list any patents? I have spent a fair amount of time looking at the images of the PCB and can't fully work out how it is handling such complex logic with the chips I see on the board. There don't seem to be any other pictures of the PCB or schematics on the net, so I am hoping that a peek at the now expired patents would give some insight.

No worries if it is too much bother

My boxes are pretty scuffed up and I’m busy working on the next video at the moment so can’t get to this right now - however here are some pictures off the net

WOW!!! I do remember opening up a Big Trak one Christmas morning. Had to be the late 70's or early 80's.

August 9, 2017 | Unregistered CommenterChris

The Big Trak (I had one as a kid) used the same TMS1000 4-bit microcontroller that Simon, and the OMNI used (the two big chips on the PCB are that chip as well). Milton Bradley was heavily invested in the TI ecosystem. Today you would source the generic chips based on manufacturing lots to get the best price, back then it wasn't so easy. You would work with a manufacturer and bundle your purchases to get the best deal you could

I have double checked and there is no Patent information written on the box, in the box, or in the instructions.

August 10, 2017 | Registered CommenterTechmoan

Reminds me of the 2-XL robot, also with 8 track tape.
