I have two different ULAs with part markings CLA2345 and CLA2310.The latter seems to be the ...

Hello Dave,

as you would like to use the 68EC000,a first minimal expansion
you could build could use it in 8 bit mode but with the clock doubled
together with a 512KB sram for the address range $40000 to $BFFFF.
So to say,you would have a 68008 but with 15MHz when accessing the
expansion memory ...

Hello,

thank you for the link,I have also found the old thread in the hardware section: "GALs for the QubIDE".

Hello all,

Wow,this looks to be a very rare QL Card! I unfortunately can not afford things like this.
Does anyone knows more about the technics of this card and how it works on the
software side? I do not see any ...

Hello Dilwyn,

thank you for your detailed explanations.First I have to say,that I am not writing a full-fledged backup program,just a quick and dirty hack in C to save the binaries out of my microdrives.
I do not handle the filename right now.I just transfer the raw file data with the 14 bytes ...

Hello Dilwyn,

thank you for your awnser.I have changed my small program and I do save the header too.(Unfortunately another Microdrive got unusable by the process of using it to much.If I loose one mdv every month then near the end of the year I will not have any left :( )
I will also try the other ...
