Re: Need a couple of games identifying

Have you looked at the Electron screenshots? Spaceman Sid looks a possibility.

Re: What new hardware would you want ?

Are those joysticks actually liked by anyone?

Is it possible to make an adaptor for PC analoque joysticks? I mean the 15 pin plug ones.

Re: Atom tapes

Have I misunderstood you? Is the WAV file a program to produce the 19200 baud rate?

Re: Atom tapes

I can't see any difference to a 1200 baud file. Is it recorded straight from a BBC? The waves are very regular and it easily converts to CSW with a baud rate of about 1201.

Re: Fave loading pic?

I would prefer the Image Converter to save to GIF since BMP doesn't have a 2 colour format. Version 87a probably works with many programs whereas newer versions will have trouble. I don't think BMP saves to less than 256. Its not allowed on this forum either. I've redone my conversion to 320x240 to ...

Something must have been fixed with BeebEm. B-Em still has the bug. Are tapes working for anyone else with B-Em?

In the thread about BeebEm V3.8 you were saying that Defender might be polling the user port for random data.

I can't see the bug now with Defender and BeebEm. Maybe it was fixed? B-Em doesn't even begin to load a tape now and removes itself after a minute.

Re: Fave loading pic?

I presume its possible to convert an image to the BBC palette with some standard graphics programs. I'm not sure if I needed to use Paint Shop Pro now. Modern programs don't usually work the same with low res. images so it has its uses.

I think the first Barbarian picture came out the best. I thought that was the original image. I find PSP3 useful for low resolution images. It has an annoying problem in that it can't access any drives other than the one its installed in. I might try PSP4. Here is a 2 colour Spectrum loading screen ...

Re: Fave loading pic?

You've used dithering with the art picture and not the photo. Thats the opposite of what usually works. When I've tried converting loading screens I usually only want dithering on a part of the picture or none at all. I often change the colours in a loading screen before bringing it into Image Conve...

The delivery charge is a lot for 1 item.

Does anyone know if the PRES plus 1 is noticeable different? Maybe they simply took the stock from Acorn.

Its unlikely to be the edge connector because it did work briefly then went faulty. I suppose I could check the logic on all the 74s with a voltmeter?

My Electrons work without it and with my other add-ons. An ordinary Electron gets a white screen and a turbo Electron has a red and white stripy screen.

Re: MMC card software mods

I've seen people saying the BBC has SRAM. They must be wrong. I was looking inside an Electron and the DRAM is 150ns. The turbo board has a 6264E3. Is that 300ns? It must abandon the Electrons bottom 8K.
