RE: Megatek Series 7000 Graphics System?

2016-12-11 Thread Mark Green
Megatek was one of the main high end graphics vendors in the 1970s and early 1980s, the other one was Evans and Sutherland. They were both largely knocked out of the market when SGI came along. I always wanted one, but my employers could never afford something that high end. Internally they are

When I was doing 68K development work in the 1990s we used the GNU C compiler to cross compile. It was a popular choice, so you might want to give it a try. -Original Message- From: cctalk [mailto:cctalk-boun...@classiccmp.org] On Behalf Of Philip Pemberton Sent: November 21, 2015 5:54

In my day job I work on computational holography and other forms of esoteric 3D displays, so I can give you some insight in how these things work. Remember these are vector displays and not raster displays, so the computational side is not an issue. You are basically looking at a pair of D/A conv

When I lived in HK (I moved back to Canada 12 years ago) you could get a visa to Shenzhen at the border. It was only valid for Shenzhen, but it only took about 15-20 minutes. You might check to see if they still do that. Otherwise, head to Sham Shui Po, Apliu Street is the local electronics ha

The desk top metaphor goes back to at least Doug Englebarts work in the 1960s. There were no icons, but the basic metaphor was there. You need to be careful when you talk about Smalltalk since there were several quite different versions of it. The early versions were far more interesting and e

I worked on the early Smalltalk systems, mainly variations of Smalltalk 76. They were there. It was the motivation for my MSc thesis which explored concurrent message passing for UI implementation including a demo of a system based on the desktop metaphor. Sent from my iPhone > On Oct 23, 201

I worked on the run time support for the early versions of Pascal on the CDC 6000 series.  Depending upon the character set determining the end of line was a major pain.  There was a loop hole in the Pascal type system that allowed you to call any PPU program directly from Pascal.  It was not w
