Re: Atom Noise Killer @ 2MHz

The switch on the ramrom board, selects 1/2 of the videoprocessor clock speed as CPU clock 1,79 mHz.
It also syncs both clocks to eliminate noise and dissables the 1mHz noise killer.

Re: Atom Noise Killer @ 2MHz

IIRC there was also a difference in timing for the 123 types according to the specs.

Re: Atom Video to HDMI Adapter

Nice job Dave, looks great, does it also work with noise killer pcb's? Maybe a simple noise killer PCB like this is good addon: http://www.acornatom.nl/atom_nieuws/1985/nr3/19853086.htm It can be designed with (bigger) or without (small) the buffers and replace the video 2114's with a 6264 8kB RAM. ...

Re: Atom tapes, WAV to UEF?

1200 baud is no problem, the MESS/MAME Atom emulator can read WAV files and if you install a PCharme or an AXR1 toolbox, you can select 1200 baud and read the tape.

A BBC option has been added to MPAGD this afternoon and will be in the next release. When the BBC and Electron compilers are done you'll be able to edit the MPAGD.INI file to include your build batch files and get developing games for those machines.
Great, thanks Jonathan.

Re: Atom 2k18 ?

Roland,

what about a switch for cassette/serial mode, then you will have 2 extra signals (cas-in/cas-out) for serial communication if they are freely programmable.
