Re: Hello from Derbyshire

Welcome, acorn machines (I only know 8 bit) sound like a good match with built in assemblers and hobby friendly IO.

Re: New Advanced User Guide (NAUG) [Remastered PDF]

I'm not always sure whether something will be in the (n)Aug or the basic user guide.
I have recently found http://www.bbcbasic.co.uk/bbcbasic.html very useful for BASIC info.

I have the duratool but have been thinking of adding a "tank" and instant value like I saw on YouTube to give it a little more initial suction.

Re: MMC - Card? - Help needed.

I was going to suggest the 6522 swap, but wanted to built up to it and maybe send a new card+adapter out first. Oh, yes it was tested ;) They are all tested with their card and their ROM (as a set) before I bag them. There was one person at Revival who didn't see there card/adapter running before th...

Re: MMC - Card? - Help needed.

I guess that you have removed it a couple of times, but can you check that the pins on the user port are clean and straight. Do you have way to test software? I need to check exactly what Card? means, I think it means that the device is working, but that the card isn't responding. Ordinary fat shoul...

Re: My Beeb inspection

The ROMs are left to right OS, BASIC and DFS, so it would swap with the current DFS (2XDFS = 2Xmemory for DFS) the other two slots are spare and high priority. Priority comes in to play if you have two languages or sometimes utility ROMs where one tries to control (usually disable) another or which ...

Disclaimer, I no nothing about this specific CPU, GPU or software!
I was going to say, not on the CPU, but it would have nearly 20ms to do it in.
The GPU could, but I don't thing we use that in RGB2HDMI mode.

I (well carol) used zoom for the first time this week for her knitting club, it was tiny, quick to install and worked with my ps3 camera.
We use Skype and teams for work, both seem very bloated by comparrison and neither support my camera! (Neither does Google hangouts).
So I was an easy convert.

Re: Hello from Salford!

Others will know better, but you might want to disable the ROM as I think it will use memory otherwise.
The Kenneth Kendall speech ROM is quite hard to find and they don't all still work, but the tms5220 isn't too bad.
