Re: MAME: IDE and other large storage devices

Here's a picture of the board: http://www.beebmaster.co.uk/HardDrives/TorchSCSI.html As yet, I've not got it to communicate with anything I've tried to connect to it, but I expect one day I'll have another go. Your board seems to match the schematic, which differs from the BeebEm implementation. Do...

Re: MAME: IDE and other large storage devices

Anyone know the type of drive and controller board found in the Torch HD system? The BeebEm implementation of the Torch HD adaptor board doesn't match the schematic at http://mdfs.net/Info/Comp/Torch/scsi1.gif, specifically the status register is completely different. Do we know where the board in t...

Re: MAME: IDE and other large storage devices

AFAIK, the emulation in BeebEm does not try to split the emulation of these components so in the case of a double-inversion there would be no point in implementing it. Exactly, BeebEm doesn't serve to document so can be misleading when it combines multiple components. I'm making good progress with ...

Can anyone recommend a decent ZX81 emulator so I can try out its Colossal Adventure version?
MAME should run it, or EightyOne https://sourceforge.net/projects/eighty ... -emulator/

I don't think any of the Level 9 adventures for the ZX81 have been archived though.

Re: Level 9 adverts

Interesting to see they offered both 16K and 32K versions at different prices, instead of distributing both versions on the same tape. Are the 16K versions archived?

Are you looking specifically for BBC adverts or for other machines too? I'm sure there are earlier adverts for the likes of Nascom.

TOSEC contains the majority of what you could find online a number of years ago, without any verification. There are a large number of bad dumps and hacks in that collection.

It looks like maybe an early release of 3.50, as the ROM versions are closely matched. It also likes the default NVRAM from 3.50, but not 3.20.

Re: MAME: IDE and other large storage devices

There's no such thing as "a SCSI" or "an IDE" image, they are "ADFS disk images". It's irrelevant what hardware ADFS uses, it's just ADFS (or HADFS of L3FS or DOSDISK). It's just a byte-by-byte dump of the file system. An image from an IDE device was what I was asking for. An ADFS image is not the ...
