I like this motherboard... Building one must be the retro nerd equivalent of finishing a 2,000-piece puzzle. ;)

Hows it play n feel as a whole???? I wanna buy one

salamander is a cracking game I used to hog it when it was in the kids club at seton sands didnt know it was on the amiga.

what model is kavanoz cam?

Just picked one of these up, brand new, for £39 !! There's one seller on eBay who does these for - seemingly - random prices, I've seen everything from £45 to £79 (all on the same seller's eBay) he's got a few on at the moment (at the time of this post) starting at £45, I was 100% sure it would be a rip-off Chinese copy when it arrived, but was surprised it was legit, haven't got a clue how he's knocking them out for under £50 when they're £250-ish everywhere else, but get them while you can !

Thanks mate!

YAY. No smoke or bangs. 👍

Sheesh Chris mate what a marathon , thinking converting my a500 to 2000ATX with bluster well worth the effort i think you need a champ award for this mate :)

omg...... when you can just about do a beep test with a meter.... N x

Really great to see those ISP devices programmed! I picked up Lattice data books, built a similar adapter on bakelite but never got the software to work. Even went as far as to code my own for the state machine. Nothing worked! Then recently found one pre-programmed for the GBA in an online store so snagged it, still waiting to try. Those old chips are a lot of work.

don't worry we are all expecting some trouble coming.

So close now

you could probably use a hotplate since there's no ICs on the bottom side solder paste would have also been a better option for the bottom side

Thanks for this. Really helpful. How do you add a middle name to Adsense? When I go into Adsense account info, there is only a panel for first name and last name?

Where can I purchase a replacement UPD4502161G5-A12 SRAM chip from?

The resistor you measure at 6:08 is actually a 470Kohm resistor which connects the output of the rectifier to the base of the power transistor BU508AF. In my case this resistor had failed and was an open circuit. When I replaced it the PSU started to "tick" again, which is the audible switching noise you were missing, and 5v and +/-12v reappeared at the output.

I’m getting the normal boot beeps but screen is black with 2 cursors in the middle of the screen do you think it’s a ram fault?

Nice joystick. I use an old Speed King It's worked for decades. (I have the red and the blue versions, I preffer the red one)

I bought one last year and it's now my most used stick. They really are nice.

I like that they have made it somewhat configurable. It reminds me of my modded zipstik I made when I was a teen, that had switches mounted on the front too, although for different functions. I think this would be a good candidate to mod too, it's quite chunky and spacious inside. The zipstik has less space inside and isn't as sturdy in terms of the plastic. Although I do still prefer the zipstik I think 🙂

It is a great stick, I love mine. NB the switch on the right-hand fire button is not auto-fire, it is to select between that button being a second button or another first button.

Gorgeous joystick. Mine would only work with the cable at a certain angle right out of the box, but once I replaced the cable nothing else compares.

I like the zip. but have heard the clones can be bad. and yes boulder dash and bubble bobble and those kind of games. Needs these joysticks :)

Great joystick. Love to use one.

How long does it take to get the certificate? I just applied. Thanks for the vid, helped a lot.

hey nice video, any ideas on an issue I have with a speccy +2A/B it plays many games fine but some which are compatible with +2A like Magicland Dizzy do not play and just crash after starting the game. I suspect RAM may be an issue so Ive ordered some new RAM chips to try. Any ideas what it could be? thanks
