Re: BBC B screen size

It doesn’t :D

So, this trick worked, thanks! Obviously it’s not permanent, but it’ll do nicely until I work out why it’s happening.

I guess for things I use a lot I can just add it to the !Boot.

BBC B screen position

I feel slightly stupid asking this question - but I've been trying to sort this out for days and I can't do it. My beeb is connected to a widescreen LCD TV with an RGB to SCART cable. All working nicely, except the top...probably...6 pixels is off the top of the screen. This has no operational effec...

Re: BBC B, Issue 7 board - cooling

I asked the same question a while back, and got the same answer...but...

Re: Help please - resurrecting model B

The tri-rail Meanwell RPT-60A supply is compatible with the beeb as it has +12, +5, -5v, but for what you want I'd guess a dual rail 12/5v power supply would work as I doubt the Torch needs -5v and the drives definitely don't. If you need to put the fancy beeb aux power plug on it, and can't fine on...

Check you've not got an off-by-one error on your keyboard connector.

I had something like that symptom (IIRC) when I put the connector on one pin out of line.

I've got most of my ROM sockets populated with BooBip EPROM adapters which does the wiring mod for you. I've got a 27C512 EPROM with 4x ROMs on it and it works very well. For about £12 each, in my view they're indispensable.
