Thomas Harte	3dbb602419	This seems to be a bit more likely.	2016-10-14 21:36:59 -04:00
Thomas Harte	138eabcff4	Continued in my effort to wire up a keyboard. Will need further to continue.	2016-10-14 21:35:15 -04:00
Thomas Harte	d8e4c488c2	Started iterating towards having an AY and a fully-working keyboard.	2016-10-14 21:18:03 -04:00
Thomas Harte	8867ad647c	Made an attempt at implementing the loopbacks necessary for diagnostics.	2016-10-13 21:47:12 -04:00
Thomas Harte	41e7eff6c8	Added a VIA. Now it's time to find out how poor my 6522 emulation is.	2016-10-13 20:50:55 -04:00
Thomas Harte	c9962f6502	Made an almost complete implementation of video. Just one row of the diagnostics cartridge seems to be off, showing thw wrong character set.	2016-10-13 19:34:29 -04:00
Thomas Harte	69920a4979	Made some basic first attempt at parsing video attributes; ensured lowest byte of ROM is readable.	2016-10-13 07:59:11 -04:00
Thomas Harte	ae48ad1bb4	Meaningful text! Albeit with the initial 'O' of 'Oric' missing. I guess control codes and NMIs next?	2016-10-12 22:03:54 -04:00
Thomas Harte	120b2d9e33	Switched to using a diagnostic ROM for now, as it'll definitely boot without initially requiring either a 6522 or AY. Have some forms appearing which imply I'm not doing badly, at least up to not knowing where I'm supposed to get character pixels from.	2016-10-12 21:52:47 -04:00
Thomas Harte	1f857c619b	Fixed timing issues. Static box of frame achieved!	2016-10-12 21:42:36 -04:00
Thomas Harte	304f0999cd	Made a faulty but hopefully creditable attempt to demarcate an Oric frame.	2016-10-12 21:29:21 -04:00
Thomas Harte	8c8a71107e	Added just enough wiring to add something that will generate the video, one day.	2016-10-12 19:20:23 -04:00
Thomas Harte	e6937d8003	Ensured that the ROM gets installed. So next for some video action?	2016-10-12 18:51:02 -04:00
Thomas Harte	4a062c616f	Added enough wiring to get Oric TAPs through to a completely unimplemented Oric emulation.	2016-10-11 22:20:13 -04:00
