Hi Richard .... I think I've got the bugs out of the VDU ... It's up on my web page. http://members.optushome.com.au/jekent/Spartan3/index.html Don't forget to refresh your browser. The Character generator ROM still needs a bit of work. John. -- http://members.optushome.com.au/jekent |

I grabbed it this morning - I'll be playing with it over the weekend. The shower always worked for me as well. Maybe someone should study that - give up cubes and install showers. Lighten up the office. Well, except I'm retired - no office. --- In , John Kent <jekent@o...> wrote: > Hi Richard .... > > I think I've got the bugs out of the VDU ... > > It's up on my web page. > > http://members.optushome.com.au/jekent/Spartan3/index.html > > Don't forget to refresh your browser. > > The Character generator ROM still needs a bit of work. > > John. > > -- > http://members.optushome.com.au/jekent |

I should have been in my cubical but I was up until the early hours of the morning fixing my HP5L laser printer trying to work out how to install a new pick up roller. I work fairly flexible hours (part time). Bad arthritis has left me with bionic joints and a rather lazy work ethic. I've been looking around for a 7 x 9 or 7 x 13 character generator that looks a bit better than what I have at the moment but I could not find much on the web. I think the one I'm using is pinched from a Comodore 64, but I must have been out by a row when I spliced it together because I had to fiddle it a bit to get number and characters to line up on the bottom line.

Sydney is about 151 degrees East and San Francisco is about 122 degrees West so we're about 273 degrees apart - figure 3/4 of a day or 18 hours ignoring local offsets for daylight savings time. Too much time studying celestial navigation... I still have a couple of issues: First, my generic 82 key keyboard doesn't work at all with the PS/2 port although it works on my Dell computer. Don't know what that's about. My Dell 101 key keyboard works at +5V but I get double strokes (press/release) which is what the keyboard sends. I also think I still see times when the counter problem reappears. If I enter an invalid (WHAT?) command and then press Enter repeatedly, as the screen scrolls it displays that odd line position as before but higher on the screen. I usually see it in the upper 4 lines, give or take. I was going to rebuild the project but, as you are up anyway, I thought I would send this along. --- In , John Kent <jekent@o...> wrote: > I should have been in my cubical but I was up until the early hours of > the morning fixing my HP5L laser printer trying to work out how to > install a new pick up roller.

I can't reproduce your problem with the display ... but I borrowed a
PS/2 keyboard and as you say ... it has problems. I've updated the monitor ROM to filter out key releases and undefined keys are mapped at $FF rather then $2e ("."). I notice the keyboard handles Shifts but not Control. I'll try post my updates soon.
