Re: ABug North 18/19/20 November 2016, Bolton

Thank you, working now and very nice it is too. (The !Runimage needs to be stamped as BASIC file, it came out as Data.) Actually the previous version crashed the RISC PC on any kind of access, even doing *. before logging on (which is my invariable practice when I do log on), but the new one works f...

Re: L3 Server Changelog

Version 1.24 did quite well really, I got plenty of FS Error 53 or Broken dir, but it wasn't killing the file server with an internal error. Well, until the last thing I tried, and it broke down with internal error &B - but then, I was deliberately trying to break it. However it does seem more r...

Re: L3 Server Changelog

I like, I like! I just navigated to one of the directories that stops part way through a *EX and ends up with No reply - and on the file server screen it said "Disc error 61 at sector ..." I suspect that's a volume overflow error because it was an illegal disc sector - so I wonder if the S...

Re: L3 Server Changelog

I'm just about to try this - hopefully I'll find it's more reliable and stable than v. 0.92 which has given me no end of trouble with FS Error 53, broken directory, and now, inexplicable no reply errors when trying to enter a directory.

Can the date-fix patch be adapted to work with 1.24?

Re: Pi-based Co-Pro on the cheap - 100MHz 6502 for £10? (now 274MHz)

I can't offer an explanation, but I can confirm that I noticed this behaviour when using real Domesday hardware with a modern, fast co-processor attached to it. I think it was at Bolton but I can't remember which occasion as I can't find any photos of a Master AIV with a bit of modern board hanging ...

"I cannot run this code" usually means there is a second processor active which doesn't understand 6502 code - this happens on the Master 512 if you try to do *BASIC, it may happen with other second processors. Make sure the Tube is inactive with *CONFIGURE NOTUBE and try again. What is th...

Re: bbc master hard drive winchester how to backup

I wouldn't try doing it via a serial link, that amount of data would take a very long time to transfer. You could transfer the files via Econet, using the BBC with the Datacentre as a Level 3 file server. For a small network of two stations you can connect the two together via an Econet clock so all...

How do I store a byte in a location in the second processor RAM from a sideways ROM? In my ROM image code, basically I have an "STA location" instruction. With the Tube off, it writes it in the I/O processor RAM, which is correct as I want it storing in the currently-in-use processor. But ...
