Re: sQLux serial and pty

It might well be a bug, but not in sQLux it seems - I was of course too quick to post here, and was able to reproduce the issue using only socat and cat pty (where pty is the symlink) - whether I've got the wrong options in the socat command line, or it's just buggy, who knows? Anyway, I'm able to w...

sQLux serial and pty

My AH QL is still out of action so I'm looking at emulators and trying the following to see if sQLux can use a pty as a serial port. I wondered whether anyone looking at the below knows right off if something I am doing is wrong or why. I start sQLux on Ubuntu with (say): sqlux --SER1 pty --RAMSIZE ...

Re: QLUB Adapter - Initial Release...

Someone correct me if they actually know whereof they speak unlike me - but I am assuming that a Spectrum emulator running on a QL would not be able to reproduce the timings in software to bit-bang the network protocol accurately - so any IF1 emulation would be bound to the QL's implementation and i...

Re: QL Pico VGA

This looks great, I was hoping someone might have a go at doing this at some point.

I am guessing that the Rs on the QL side might also provide some meaningful protection for the ZX8301 (given what I've read elsewhere?)

Re: RAM fault rabbit hole

Many thanks everyone. When I unsolder the repair on /WE between IC14 and IC15, the Minerva RAM fault screen returns: 70827600 F082F680 00020000 I just did this again for my own confirmation. So if this signal can still come out, and comes from the ZX8301, then that chip is at least working, am I rig...

RAM fault rabbit hole

OK, so, to start with - I'm not going to ask or expect anyone to remote-diagnose my machine, instead I will ask a general question someone might be knowledgeable about: If Minerva reports a memory fault due to a broken track, and the track is fixed, might there now be no video (TV says "No Sign...

Re: QL to PC network

Here's an updated version. Now it sends and receives files, optionally prepending or stripping a header respectively. Three timings (ah, ql, zx) supported. Also a utility for generating said headers. (Trying to port to C may not have been the best idea, looking back...) Also included is a simple &qu...

Re: QL to PC network

OK I'm relenting here and attaching said Python. It uses pySerial and sends a file with source and destination specified (and timing profile). Anyone wanting to use it will probably need to edit to get the serial port name right (and revert my AH ROM timing tweak). Only tested on a Mac so far. It co...

Re: Sinclair Memorial Weekend

A bit late of me but thanks for drawing my attention to this @Cristian! I went along to this and had a really good Saturday morning. Just a little QL stuff but very interesting. Made a day trip to Cambridge out of it. I was actually struck by how stylish some of the audio products were. Also went ho...

Re: QL to PC network

There is no reason why a native PC app couldn't be written to allow at least simple file-transfer between QL and PC over the QL network using the QLUB. An 'exercise for the reader', as they say - and I understand that another forum member has devised such an app in Python... Just seen this - I'm ha...
