Re: Miracle Systems Gold Card

Hard to tell from the picture, but this looks suspiciously like a bridge between the 9V and 5V power rail (input and output of the 5V regulator seem to be bridged) People who built their QLs into PC cases often did this "back in the days" to supply expansion cards with 5V from the PC PSU i...

Re: Miracle Systems FLP size determining algorithm known?

From the SuperGoldCard manual (emphasis mine): The Gold Card and Super Gold Card incorporate a software fix for a problem when accessing Mitsubishi ED disk drives in the form of a number of rapid steps of the drive head. This rapid stepping of the drive head, referred to as a jiggle, when applied to...

Re: Slowing down QPC 2 or uQLx to original QL speed

Stephan, uqlx doesn't have any in-built mechanisms to slow it down to QL speed - It was originally developed when the emulator even struggled to keep up with an original QL. QPC knows the SLUG command that can slow down interactive programs (that wait for keyboard input) Then there is a number of pr...

Re: Running game "Werner" under uQLx

QEmulator has added (all in good faith, I suppose) another level of complexity to the topic of QL file headers. When you copy a QL executable to a non-QDOS file system, the 64-byte header that belongs to the file is normally lost. Daniele has devised a scheme that packs the header in front of the ac...

Well, if you want the boot to happen within reasonable time, yes. QubIDE retries connecting to a disk for about a minute, if I recall right. But the boot should continue normally after that time.

Re: Assembly Language eComic - Issue 7 now available

I've fixed a small bug in the code submitted by Tobias in Issue 7. There was a use of A7 in a register list that should have stopped at A6. (That's the sort of mistakes I make!) Wolfgang spotted it and let me know. I guess whatever you (I) do, there's always that last error you (I) miss ;) Sorry fo...

Re: Formatting a QXL.WIN file

Then why not simply transfer the SD card to a PC running QPC and do the renaming there?

Re: Formatting a QXL.WIN file

No need to reformat.

Download Per Witte's QWirc - You can change disk labels on the fly there (Right-click on the label).

Can be found on Marcel's QPC demo disk for QPC2, if I remember correctly.

Re: QL Net server to back-up Spectrum files?

At the last German meeting in Mahlerts we on-the-fly-connected a QLAN-enabled Q68 and a Spectrum with Interface 1. It seemed to work relatively flawlessly. Transfer back and forth was fine.
