Re: Issue 8 discussions...

Things are going slow right now.

I'm investigating a couple of low level decisions about the video system. I'm not really happy with any of the options that have been presented to me, or any I have devised myself. I'm still noodling it out.

Re: Starting programming.....

I always just used flat files or linked lists. It's not like a QL program usually has complex data requirements. I personally prefer flat files. They occupy more memory, but they are quicker to index and easier to save/load only the specific entries you want if each record set starts on a ^2 boundary.

Re: Membership payed but nothing happened aftewards?

QUANTA is aaaalmost dormant nowadays.

They still release a regular magazine, but without an editor, that's a tough job.

Re: Get info when QL is ready with screen redrawing?

It's also an option to turn the video display off while the screen is being redrawn, so the redraw happens during the dark spell, if that is the effect you're trying to achieve?

Re: Microdrives- has anyone managed to replace the tape ?

I saw this process at a factory in Basildon in the early 90s. I was buying bulk custom wound to length tapes, and they were buying their tape on huge 20cm*20,000 metre rolls. (or something like that. It was a long time ago.) I went there to pick up 5,000 wound to length tapes. The cutters are circul...

Re: Hardware pointers and cursors.

when talking about "Mouse buttons reversed" you should be pointing out "reversed compared to what?" Windows (that sort of nailed the left/right-button usage down) wasn't by far as predominant when the PE was designed as it is today. MacOS only had one mouse button, and X-Windows...

Re: Hardware pointers and cursors.

Sorry, what difficulty are you even talking about? The difficulty of having the code modified to use more capable graphics hardware. All this potential video hardware would do is split an already small user base even further, because most platforms would not have this hardware feature. Then we shou...

Re: Modifying modern floppy drive for QL

I have done a few drive mods on late 90s drives to remove a 0 ohm resistor and convert them to drive 0.

It is possible to modify a Sandy SQB v3 to use HD drives. If the WD1772 is socketed, which most aren't, it's a lot easier.

Dave, I didnt mean to sound as harsh as it came across; I just wanted to try to save you from another distraction ;) Being a sufferer myself, Im familiar with how the imagination races ahead, generating ideas at thousands of times the speed of any chance of implementing them! Im sure many people he...

Re: Hardware pointers and cursors.

Look, its not that I wouldnt want a new graphics accellerator standard or anything, but I wouldnt want one designed by someone who didnt have the first idea about how the current system works. Afterall, theres about 30 years worth of software using it, which youve obviously decided to negate. Why s...
