Comment 37 for bug 1530530

Created attachment 680175
result from test iso 7

The memory layout is shown, but only the image shown in the attachment (below memory layout) is what's gotten after that. Waiting or pressing Esc does not change anything. That is, only the diagonal lines background that was also shown with test iso 6 (aside from top left corner that had other info), with nothing else.

Note that while the background is drawn immediately, any characters outputted are v-e-r-y slow to output, so any timing assumptions may be wrong. As mentioned at https://johnlewis.ie/alls-well-that-braswell/ - if one would have a full screen of text output, it might take a full minute to draw. Think of a 300bps modem line. With short and few lines like with test iso 6, it only took maybe 10-20s or so though.
