Re: what should i write next?

Bit late to this thread and skimmed it a bit. Mention of Asteroids made me think of the emulator for the atari 800 - http://members.aon.at/nkehrer/ast800xl.html - he's also done sprint for the 800 so you already have a conversion in common :D Found out about that when I was thinking of the possibili...

Re: BBC B sideways ZIF socket

Not much to see really, all you're doing is taking each pin from the socket and wiring it to a remote pcb with a zif socket. bit laborious but plodded through it while nursing a hangover and listening to TMS. Just need some stripboard, turned pin header strips, ribbon cable and a ZIF socket (think I...

Re: BBC B sideways ZIF socket

Just built a zif socket plugin using some stripboard and a ribbon cable. seems to work fine with no resistors or capacitors, might add these if it turns out to be unstable. Combined with the diy rom/ram modification on retroclinic it gives me 4 rom images at the zif socket which are easy to program ...

Re: Loading a game from a cassette tape

another possible fault with old tape decks is the drive belt going. t's a black neoprene band. these get slack or harden with age and can start slipping. replacements are still available.

although i still own a tape deck i'd be loath to use it. some things are best left in the past. :wink:

felix in the factory (STH collection).

tested the STH collection disk with 'felix in the factory' on real machine and emulator, didnt work. found the file 'factory' was shorter than expected it so copied it over from the single game release. now works on emulated and real hardware.

Re: IDE/CF Adapter

I bought an incredibly cheap one (2-3 quid) originally for the Amiga, which I later used for an A3000. no circuitry on the adapter other than an LED and a master/slave jumper which leads me to believe <at least some> CF cards are compatible with IDE standards. I'd also guess that whatever the price ...

Re: 2015 Newbury Rally and Amiga A600 Issue

the usual suspects in my experience are the two caps right behind the audio output jacks. beware they're surface mounted, hard to desolder and the pads have a tendency to lift (possibly due to the gunk the caps leak onto the pcb).

Re: so i tried to upgrade to os 3...

If the ROM set is from the internet, then it's not appropriate for being burnt to EPROM. It's sequential, whereas the real ROMs need to be interleaved. I'd expect this if i was using a single 2meg image but the ones i tried were 4 x 512k. the images were from here; http://www.4corn.co.uk/aview.php?...
