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.

Re: Hardware pointers and cursors.

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...

Re: Hardware pointers and cursors.

The advantage of the QL is that the PE can be not used if required. But in SMSQ/E the PTR_GEN, WMAN and HOTKEY systems are builtin and part of the operating system. But most old software does run. But I did not think that the Extended Envoironment builtin into SMSQ/E should really of been modular, ...

Re: Hardware pointers and cursors.

Hardware sprites? Blitter engine? DMA transfers? Let 'em roll! It's a surprisingly simple system to implement and interface - it's just making the OS know about it. For games that were written for it, that isn't even necessary and I would provide full example code. The PE as such, though, won't ben...

Re: Hardware pointers and cursors.

I agree that it is hard to get to grips with. I bet that if you were to delve into the innards of Windows, or any other modern WIMP, youd find horrors beyond belief. [SNIP] The thing I like about the PE system is, that considering that it is a not bad, complete implementation of a WIMP for the 8/16...

Re: Issue 8 discussions...

Deadlines. I suck at them! UltimIDE will be here in 2014!

All I can do is tell you my progress, share the decisions (some hard, some easy) and let you figure out for yourselves when it'll be a thing.
