Re: Faulty 6502 Co-Pro

I've just burned Tube 1.10 to a 2732. I've also mirrored it into both the upper and lower banks, and similarly, I can't get the Tube banner with that arrangement. That sounds like a problem I've been having, although I can't explain why you might get the Tube start-up message with 0.01 but not with...

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. As seen by everything in ADFS above the level of the device driver/hardware, yes...

Re: ADFS 'Dir Full' error when it's not full problem

It can be a bit painful copying masses of files over Econet, especially using the L3 server as it has to allocate space sector by sector as it goes along. I don't think there's a way (like using ADFS Explorer for example) of "dropping" files onto a L3 partition on a disc image. JGH's AFSFiler will a...

Re: ADFS 'Dir Full' error when it's not full problem

If you already have a disc image of the original CF card then it should be possible to rename it scsi0.dat and put it in a directory called BeebSCSI0 on a micro SD card and it will work with the BeebSCSI board, see what that makes of it.

Re: ADFS 'Dir Full' error when it's not full problem

Without seeing any printouts or FS map information, I can only think of three ideas: 1. The copy program is getting confused during the copy and might not be trying to create the latest entry in the correct destination directory, and where it is trying to create might be full. Treecopy doesn't alway...

Is there a way in BBC BASIC to deal with errors using ON ERROR which doesn't upset a FOR...NEXT or REPEAT...UNTIL loop?

Re: how to shift break to run !BOOT when in drive 1

The 8271 DFS defaults to drive 0 when using SHIFT-BREAK so you can't autoboot from drive 1 (or 2 or 3). You'd have to use *EXEC !BOOT if OPT is 3 or *RUN !BOOT if OPT is 2. Master 1770 DFS (probably the same for Model B 1770) does remember the drive on SHIFT-BREAK so it will autoboot the currently s...
