Due to technical difficulties during the filming of Logo developer, Leigh L. Klotz, Jr. during the May 2017 Bay Area Maker Faire, I had to go over to Leigh's place today and re-film his talk. Instead of a few minutes of behind-the-scene happenings that he related at his previous talk, this time he went more in-depth into the creation of Logo, naming names, describing the process of bringing it to market, and identifying the Logo-compatible computers and their limitations. One bit that I did not know... the company for which he worked, Terrapin, tried to develop a version of Logo for the Commodore 128! He said that it remained unfinished and thus was never commercially marketed. If only the remnants of that C128 Logo were still around, Robert Bernardo Fresno Commodore User Group www.dickestel.com/fcug.htmJuly 29-30 Commodore Vegas Expo v13 - www.portcommodore.com/commvex |

If you are talking about the "turtle graphics" education tool for the C64, then I would be interested in making a C128 port! I remember LOGO on the C64, and I thought the built-in GRAPHIC capabilities of C128 were very similar, and I instantly loved the C128 for that (also the Plus/4). Of course the original ROMs of the C128 have some bugs with relative-coordinate graphics (which is mainly what I remember from LOGO). Anyway, it seems the tedious bitmap routines are already present in ROM, we just need some love and care to port LOGO to the C128. The bright side is the RAM code should be much smaller in size since a lot of the stuff is in ROM. Unless we include the VDC, which I would do... in that case the code would be probably be *bigger* in size, but hey, the C128 has twice as much memory, so no worries.

If you are talking about the "turtle graphics" education tool for the C64, then I would be interested in making a C128 port! Whoa! Excellent idea! After hearing Leigh Klotz, Jr. talk about the how the C128 port of Logo was discontinued, I was saddened. (My guess... the company, Terrapin, saw no profit in porting it to the C128.) However, if you can do it, that would be amazing! Do you want me to give you Leigh's contact information?

Cool, I thought that was what you referring to, RobertB. So I will put this on my "bucket list", but it may be a long wait because of new video port I am working on at the moment. And yes, cdawe, I fully intend to support for both graphics chips (40 and 80 columns).
