Re: Piggyback 4164 to Diagnose Memory Fault

I know I keep harping on about that solder blob on the 2nd pin in your picture. I had a quick look at the circuit diagram (issue 5). And I think that is pin 7 of the RAM chip, and that large track is most likely either ground, or 5Volts. Pin 7 is the DA1 line which goes to IC19, (which you've been l...

Re: Piggyback 4164 to Diagnose Memory Fault

I don't know if these pictures of bare boards will be of any help viewtopic.php?p=24839#p24839

If you blow them up, you can just about follow the tracks.

Re: Minerva4Q68

Thanks for the feedback. The documents are an edited version of the one's I did for the Q68, (which was and edited version of the QPC2 one's), So that COLOUR_QL was something I missed. As Jan said earlier, the WIN driver's a bit limited. You can only set the WIN drive associations with the menuconfi...

Re: Piggyback 4164 to Diagnose Memory Fault

Looking at the photo, Is the pin 2nd one down on the left supposed to be connected to that large piece of track. Also there are a of solder splashes that might be bridging tracks, Give them a scrub with an old tooth brush, and/or scrape them off with a small (watch makers) screwdriver. Hi Martin, I...

Re: Minerva4Q68

Here's the first version of my Minerva4Q68 keywords and concepts documents. They are in Libre office and PDF versions.

Please let me know if you spot any errors or omissions.

Re: Minerva4Q68

Thanks for that. I will add a warning in the FORMAT description to not format WIN drives, and to do it in SMSQ/E. I have already added a warning in the concepts document to avoid starting Minerva with CTRL-Fx. Another quick question, Is the QUB device like the SMSQ/E one , in that it should only be ...

Re: Minerva4Q68

I've had a play with this. But I've found I can't do what I wanted. I wanted to start Minerva, then use WIN_DRIVE to mount whatever QXL.WIN file I wanted. But there's no WIN_DRIVE, or CART_DIR$ commands in Minerva4Q68. You have to use menu config to set the Minerva4Q68 WIN associations first. I supp...

Minerva4Q68

Just a quick question.

If I start Minerva4Q68 from SMSQ/E with LRESPR. Once Minerva has started, Can I safely mount QXL.WIN container files in Minerva4Q68, that were mounted by SMSQ/E beforehand. i.e. When Minerva4Q68 starts, is SMSQ/E completely gone. And any open files are closed.

Re: Has anyone ever tried "long filenames" from H.P.Recktenwald?

I wrote this https://www.qlforum.co.uk/viewtopic.php ... ept#p27694 some time ago.
It was just a proof of concept, and I never went any further with it.
