Any native 68K hardware including 68060 has become slower than emulation on PCs. I wonder how people see 68060 systems today.
I love my Q60 and like Derek I would like the Q60 to be able to display on flat screen monitors or HDMI TVs.
The benefits of speed are relative as you say Peter. The Q60 boots faster than my PC which is a fastish PC with a core i7 3.5 GHz, gaming graphics card etc,etc. But in benchmarks QPC2 scores higher than the Q60, but not dramatically so. When I provided QTOP index figures for you for comparison with the Q68 I also showed on my blog the QTOP index for the Q60 at max speed. This was 194.84. QPC2 on my current PC gives a QTOP index of 473.86. The numbers look impressive but the speed increase on this index is only about 2.4. The Q60 I have was one of the early ones so has been in action since probably about 2002/3, the PC is much younger and has had a lot, lot of cash spent on it to keep it capable of coping with expanding PC software. In the scheme of things the Q60 still has a good turn of speed compared with emulation sitting on expensive hardware bought for other reasons.
The Q60 display with its lower resolution I find is more comfortable to use for running QL software new and old, programming and reading QL documents and getting in to the QL hobby than QPC2 on the PC with its greater screen resolution. In itself the Q60 is no slouch. So I would love the Q60 to be able to display on a modern flat screen to get the 19inch CRT off my desk, I would not mind a converter attached to VGA out of the Q60, or an updated modern Q60. The cache problem with Qlib is not so much a Q60 problem as a Qlib problem. If only the QLIb sources were available to modify. As for connectivity - USB, CD, Compact flash and SD card. I bought one of the early USB wiz devices and it worked with the Q60 serial ports. A possible up to date approach as USBwiz is no longer produced could be linking a RPi via serial as a USB, printer, SD card server for file transfer. Although IDE to CF adapters and SD card adapters can work with the Q60, but not all of them.
