I don't think that a so slight speed difference could be sufficient to produce such results. Consider Loop time formula. LoopTime[s] = TapeLenght[mm] / ( RollerDiameter[mm] * PI) / MotorSpeed [r/m] * 60 Another information about that top-performance cartridge: the speedtest reported (and continues ...

I just want to be able to plug my QubIDE and Gold Card into the QL at the same time, in order to be able to run floppies and a hard disk on one machine at the same time. Out of curiosity: What is the advantage of this much larger solution over QL-SD, which is also Qubide on SDHC card, just as conta...

Welcome!

I did't pay much attention on which unit got the best performance. I'll do some tests After some tests I can say that the best results are averag...

Your MDV2_ seems on average a bit slower, is that your star performer? Usually it is the drive mounted as MDV1_ , as MDV2_ picks some noise in the QL case, the QL board is a subject to applying the documented mod for better drive performance. Thanks for your comments. So did you apply the famous &q...

I finally succeed in demagnetize my mdv heads, so I'll run your speed test soon So here are the values for my staight-edged microdrive units (seconds/rpm). Cartridge A , first run: mdv1 -> 6.75/2396 mdv2 -> 7.5/2156 Cartridge A , second run: mdv1 -> 6.75/2396 mdv2 -> 7.25/2230 Cartridge B , first r...

The emulator runs perfectly. It also maintained the previuos presets I prepared. Thanks!
