Re: Two A3020's out of the loft

The A3020 keyboard membranes can be opened up (carefully), washed clean, dried and reassembled. Hopefully this will solve the problem. Definitely snip the batteries out and give the PCB a quick wipe around where they were, while you've got the computers down from the loft. Those batteries have a ve...

Two A3020's out of the loft

I was away rummaging in the loft (as you do) looking for various items, and I located a box containing two A3020's and a mouse, so I bought them down the stairs to take a look at them, and see if I could get them to display anything on an old small LCD tv with VGA input (but no Freeview, etc. and on...

Re: Anyone ever corrected the 6502 mnemonics

Have finally had a good rummage and have found my old decrepit user guide, and even though the whole index at the back is missing, presumed dead, the 6502 instruction set was still there, albeit loose. The mistakes are as follows: Both ROL (zero page X) and SEC (implied) are listed as opcode &36. ST...

Any mediums out there?

There's this song from a Beeb game in my head. Trouble is, it's almost impossible to describe how it goes, and I don't think my singing is up to it (tone deaf). Guess this thing's going to bug me until I get Beebem on and go through my disks.... And, isn't it funny how the memory gets jogged. Whilst...

Re: Img2BBC image loading appears skewered

As MartinB says, make sure you change mode and then immediately *load the screen. The reason for this is that due to hardware scrolling, the start address of the screen may change if you have scrolled down below the bottom of the screen. To see this in action, try the following: MODE 2 *. *HELP *LOA...

I used to play a great two player game called Barrage. You and your partner (foe) play as an army, each with a town nearby. You start with 100 armies and 100 civilians. Each time you start the game generates a new landscape, and during the game the wind direction and strength changes. You have to en...

Re: Replacing the circuitry with modern equivalents?

Of course, another option is to recreate the video ULA logic and then add the extra palette RAM and DACs and have it as plug-in replacement for the original.

Re: 360K Drives, Windows XP and Omniflop

I never got Omniflop to work with any windows version, so I gave up and got a USB to RS232 cable, but that was awfully slow (and didn't seem so reliable) so I spent some extra cash and purchased an external RetroClinic DataCentre.

Best £70 or £80 I've ever spent.

Can't remember off hand what exactly but a few of the opcodes had the same number but different mnemonics.

Very confusing, and hard (at the time) to know what was right or wrong.
