Re: Asymmetric multiprocessing...

So far we have (including IRC discussion and computer lab discussion: A 6502 and Beeb tube implementation 80486DX and run Windows 3.1 in a window on the QL? RiscPC style! ATmega, and the variety of IO/datalogging it could provide. A large FPGA as the ultimate dev board that can be anything you want...

Re: Long File Name device driver

Excellent - there was the sub device driver also, but from memory it failed on WDIR or WCOPY.... Rich Not sure if I tried WDIR or WCOPY. If you use WSTAT, it gets a little upset if it encounters a long file name that has been chopped down to 36 characters with the '....' in the middle. The file siz...

Long File Name device driver

I have been playing around with a directory device driver that supports long file names (up to 72 characters). By adding a path to the start of any file name provided by the operating system. On a per job basis. So each job could have a LFN1_ device pointing at a different directory on the same stor...

Re: Hello & help needed with QL networking and TK2

Just to check. When you install the ROM, you mean a physical ROM and not a software copy of Toolkit 2. You need an actual ROM IC for the timings to work. I'm not too up on the actual hardware connection and handshaking. And what I do know comes from the SMSQ/E sources. Which is basically the TK2 net...

Re: Hello & help needed with QL networking and TK2

I'm pretty sure that Toolkit 2 changed the network timings a little bit. See http://www.dilwyn.me.uk/docs/ebooks/QL%20Toolkit%202%20-%20Tony%20Tebby.pdf around page 50 it lists the handshaking network protocol for Toolkit 2. You might also try using a lower network station number than 63, as that is...

Re: Today I Received...

The Prism modem I bought came as standard with a gray case, not a black one, and I got a custom black one from the manufacturer. The front and back where hand cut, so they may have made them from what they had laying around. Like I mentioned, the one I had was a very early unit that required firmwa...

Re: Help fixing a dead QL

It sounds like you have the facilities to unsolder IC's without damaging them. You also say you have lots of spare RAM chips. So why not unsolder all the RAM chips, check the PCB, fit IC sockets, then replace all the RAM chips at once. If this fixes it, then test the old chips one at a time to see w...

Re: A question about OPEN

Do you mean sort of "anchoring" a virtual device off some point in the file system, like QPC's DOS device? In theory, I think something like that could work. The idea is, The file system on the media supports 128 byte file headers, with 72 byte file names. When a file is opened by an appl...

Re: A question about OPEN

I don't know why you need a job id for a system-level I/O open, The job contains a pointer to a string, which I want the open routine to add to the supplied file name. I am tinkering with a file system that supports long file names, but maintains compatibility with the operating system and existing...

Re: A question about OPEN

It would seem like a lost opportunity otherwise, as the job ID is required to call the open routine.. Either way, it would be good to get confirmation as, if correct, this should be nailed into the documentation. I tried it in QPC2, and D1 is not the job ID. I expected that 'smsq\ioa\open_asm' was ...
