Yes but that is because the blitter is designed to interface with the ST shifter. For something resembling blitter with a VGA card you need a VGA card that has its own graphics acceleration, like an ATI Mach64. Where as the ET4000 basically just acts as a frame-buffer without any acceleration.

Yes, but there is no way IMHO - correct me if I am wrong - to get an ATI Mach work in a Mega ST.

Nice results with your Mach32.

Cheers.

The Nova driver make use of the Blitter in the MACH32 chip.

Had some time today to test my slim optical drives (Panasonic UJ-875 and TEAC CD-224E).

Both were set as slaves on the Lightning ST IDE port, recognized in HDDriver (had a weird byte swapped name though) but did not work with ExtenDOS 4.

I guess you really have to get a supported drive as per Anodyne Software specifications if you do not want to try miscellaneous drives and spend money for nothing.

Anyway, those two drives were primarily bought for my Amiga 1200 project, so I will make use of them sooner or later.

You can try to use the Anodyne Driver Suite with a USB CD/DVD over the Lightning ST. You can use your IDE drives over a USB/IDE Adapter/Controller ...

Yes, it is also an option but my plan was to fit an internal slim drive in the Mega ST.

I can get ExtenDOS compatible ATAPI drives, but there is definitely no room for 5.25 ones in the pizza box.
