For example, the difference between MC68000G8 and MC68010P8.

I am talking about the difference between the "G" and the "P" packaging for example.

Nope, I don't think this is true. You can see this in the different package types.

I mean that it was based on a die shrink, which is why it took so long.

http://www.easy68k.com/paulrsm/dg/dg17.htm "As a result, work on a faster (shrunk) 68000 has been set aside and all hands are concentrating their efforts on the 68010. We understand that the 68010 will be the chip targeted for speed improvement. The good news is that the 68010 is pin compatible...

I mean CSDs.

Was CSDs really distributed on 2.88MB floppies?

I wonder if this change was to avoid partial register stalls on the AH register.

I am talking about HD floppies. Edit: Though this is a good time to mention that cobalt is probably far common than barium, but...

I doubt HIMEM had an option to shadow ROM into RAM. EMM386 might have though.

Not to mention the demand for cobalt.

I wonder if the fact that it was based on barium ferrite made them unattractive to software companies.

Actually, I wonder if the pixel clock is actually halved or if the pixels are just doubled.

Interestingly http://bitsavers.trailing-edge.com/components/chipsAndTech/82C452_Super_VGA_Graphics_Controller_199109.pdf : "The maximum display bandwidth is 200 MBits/s - 25 MB/s at 8 bits/pixel" I wonder if this required faster DRAM chips for example.

I know, but there was almost certainly plenty of alternatives by 1985.
