Re: A new Warlords emulator for the beeb (was Writing a ...)

Tried it on one of the Masters in OS 3.2 mode and that seems to have done the trick(y) as it's now working. :) Good news, I can't think why it would lock up on 3.5, I could understand it if it worked, but the paddles didn't respond. Did you get to the bottom of the dodgy fire button? Here are some ...

Attached is the wiring diagram as best as I can see that I have ended up with. The DiaDiagram is the same thing but in Dia (visio like program).

Re: A new Warlords emulator for the beeb (was Writing a ...)

This seems OK on a Model B, B+ and Master although, we haven't got it working with a DataCentre yet. This game requires one 16K sideways RAM bank, the disk image attached, 1-4 paddles (for 3 or 4, an adapter is required, details to follow) and your own Warlords arcade game ROMs. I have not put the g...

Fitting the missing light pen strobe on early beebs

I have been informed that some of the early beebs didn't have the LPSTB (Light Pen Strobe) fitted, which I guess means that they don't have the track on the circuit board. Looking at the circuit diagram, it looks like the Analogue 15 pin connector pin 9 (the one on the same end as +5v) LPSTB connect...

Re: Cowgol achieves first light!

Great start, well done.

When you are looking at peephole optimisations, it might be worth comparing your output with that produced by Daniel Dallmann (aka Poldi) 6502 optimizer (attached). I'm not saying use it, although I guess you could, I'm just saying it gives you a minimum target to hit ;)

The demo is only one life, the multiple lives are a great hack by Mick, so starting again makes sense.

I'm trying to sort out Warlords on the master when it wo...

Having had another look, I guess an LS157 would be a more appropriate solution as it has four 2-input multiplexers in one chip.

Re: A new Warlords emulator for the beeb (was Writing a ...)

I won't be home until Friday, but could lend you mine.
The paddles would also need the extra white wire adding and may need the other wires on the pot swapping around.
I only have one set of Atari paddles at the moment.

Re: A new Warlords emulator for the beeb (was Writing a ...)

The nand gates are to allow the light pen strobe (thanks Flynnjs) to be used to select between two sets of fire buttons so that a total of four fire buttons can be supported to go with the four paddles. There is probably an easier way of simulating a dual gang two way switch controlled by CB2 (iirc)...

Doing the wires version takes a very long time, but I will try and get a small batch of PCBs ordered once I have got home and checked the design.

Hackaday agrees with the CO2 and fan method http://hackaday.com/2017/08/02/eradicating-mosquitoes-from-your-backyard-with-seltzer/#more-267216.
I suggest a white background to see them, CO2 to attract them and either an air rifle or cricket bat to kill them ;)
