Thomas Harte
69f520428d
Makes a first, ugly attempt at a 'new machine' dialogue for the Mac.
...
Which has implied getting much more specific about MSX disk drive attachment, and has prompted an excuse to offer the ZX80 with the ZX81 ROM.
2018-04-02 22:42:41 -04:00
Thomas Harte
33084899d0

Thomas Harte
6d464557a0
Reintroduces a warm-up run for the C1540.
...
That simulates the normal real-life scenario of switching the drive on slightly before the computer, and causes it to function correctly from immediate fast typing on an American Vic.
