68060 based QL system?
Posted: Fri Apr 06, 2018 9:40 am
Any native 68K hardware including 68060 has become slower than emulation on PCs. I wonder how people see 68060 systems today.

- You easily pay over 500 € to actually get a fast Vampire accelerator
If you look at anything that was available, the factor was 1.2, not 3, versus Amiga 68060 accelerators. I doubt it would be any faster than a QL-specific 68060 board at all.
Like the open-source 68K FPGA cores, their closed-source core will probably have QL-specific bugs, which don't surface on Amiga/Atari. No way we could fix them.
The Vampire plugs into a 68000 socket - that would make video circuitry with SMSQ/E driver support very slow.

martyn_hill wrote:e) (Something that interests me, perhaps more than it would some other users) Which option maintains the option to develop simple HW add-ons most readily (e.g. allowing for an 8-bit expansion interface at 'legacy' bus-speeds.)

The Vampire comes with HDMI video circuitry
