Re: Ample Rom query

Thanks. I'd already discovered the cracked version and associated discs, which will probably be more useful on a day to day basis. Unfortunately, that method doesn't satisfy my OCD and need for things to be as original as possible. CRJ pointed me in th right direction regarding the rom ID and how th...

Re: How to open an E01 Filestore?

Just given it a go.
Front and back pieces come off using fingernails on underside and levering up and away from case.
Side pieces come off best using fingernails on top surface and levering up and away.

Re: How to open an E01 Filestore?

The rear and front come off in the same way. I always free the lower edge first.
It’s been a while, but I think if you squeeze the side pieces then little lugs on the lower edge come out of holes in the case and the sides can then be swung away from the case.

Re: Ample Rom query

I must have misunderstood something, somewhere.

The intact rom which I have is ID 70062. Call me “Dr Thicky”, but is it possible to encode this value in the way the 8BS article describes?

Re: Purchasing CP/M Software for the Z80 second processor

The Wordstar 3.3 disc label proclaims it to be in BBC Z80 DFS format, which is promising.
I may well have dBase II as well.

What’s the forum stance on posting images of these? They’re old and obsolete but the parent companies (do they still exist?) may care more than Acorn ones do.

When I acquired my Z80 2P, it came with a box of other discs. These included several copies of Wordstar.

Re: Atom Econet Adapters

If you go for (5) then some of the components need to be changed for it to work on an Econet with BBCs on it.

I’ve got an Acorn app note (from before they called them app notes) that I need to get scanned in which details the changes required. Along with a load of other similar Acorn documents.

Sadly not. I acquired all my Z80 stuff nearly 25 years ago now and haven't used it much for about 20. So far as I can remember, I got all the Z80 software from Trintity College, Cambridge when they were selling it all off. The Winchester Utils presumably came as part of that lot. They only had Z80 s...

I'm trying to copy my Master 512 disks onto my Gotek drive. The Acorn DOS+ disk works fine as an ADL image, and I can create new bootable 640K disks without problem. However, nothing seems to work for creating the 800K Acorn DOS images. I've tried downloaded images of the GEM disks, and formatting n...

Don't know if this is already widely available. It's an image of Acorn's Winchester Utilities Disc for the Z80 Second Processor.
