worth remembering that hdmi and DVI are equivalent in terms of what is needed for a computer monitor. hence hdmi to DVI adopters are very cheap. -Steve > On 28 May 2016, at 18:49, Dave MacFarlane wrote: > > That's exactly what I'm doing. I don't have a monitor with HDMI within network-cable and power-cable reach to hook it up to, and the last time I hooked it up to my TV my toddler tore the usb/power cable of the Pi in two, so I can only try debugging it when he's not around.. > > (And Go 1.6 or later for Plan9, but 1.7 or later for ARM, for the record..) > >> On Sat, May 28, 2016 at 1:34 PM, Skip Tavakkolian wrote: >> a quick and easy way to get a local Plan 9 terminal is to use 9Pi (Plan 9 on Raspberry Pi). with Go 1.6 and later you can cross compile for plan9/arm. >> >> >> On Sat, May 28, 2016 at 10:24 AM Dave MacFarlane wrote: >>> Either I'm going insane, the default Plan 9 /dev/draw in-memory implementation >>> doesn't implement draw(3), or possibly both. >>> >>> When I do the following, it works as expected under both drawterm and a locally mounted instance: >>> 1.
