Re: Problems with/after ROM replacement, vDrive and Exapanderam

Hi,

The problem maybd related to the broken pin on the Minerva.

But Minerva should improve the Microdrive access, as AH rom is full of bugs.

Do you have the 2 resistors on top of the 8302? This improves the microdrive reliabiliy.

Re: QXL Networking

Hi Martyn, The Altera EP1810LC-25T fitted to the QXL cards is rated to run at a maxiumum speed of 50Mhz. I think overclocking the QXL by putting an Oscillator of a greater clock speed of 50Mhz will cause the EP1810 to shut down or become too hot to run. I thought about fitting a 68RC060RC50 CPU with...
