“High Resolution Graphics MK. II” is a software high resolution graphics program for the TS-1000 line of computers. It has the ability to plot points, unplot points, write in upper and lower case, test a point on the screen, invert the hi-res screen, and copy the hi-res screen to the printer. The resolution comes as 192 x 128 but can be expanded up to 192 x 256 in some applications.
The program auto-runs after loading and gives you an example of hi-res with both upper and lower case text telling where the addresses are for each operation. You use RAND USR XXX in your program each time you wish to access ae function. Each function is easy to use and examples are given.
Included in the documentation is a short program which will allow you to draw on the screen using the arrow keys (see example), and a test program for writing in upper and lower case.
As an example, to use upper and lower case, you must first clear the hi-res screen using RAND USR 16572, call the hi-res routine with RAND USR 16514, place in a PRINT statement what you wish to print in upper and lower case (using inverse characters for upper case), POKE 16417 with the line you wish it to appear in, and call the print routine with RAND USR 17285.
The characters are not the best in the world; I like the upper and lower case letters on the 2068 much better. If I knew where the character table started, it would be easy to change to a more pleasing character set.
Another thing that isn’t explained in the manual is that you must be in SLOW mode in order to see what is being printed. The plot routines are much quicker than the Sinclair plot.
The code is short and only takes about a minute to load. I am very happy with this program. It does a lot and is easy to use. Best of all it is inexpensive. They also list a word processor using the hi-res routines which should be pretty good from what I’ve seen here. They state in several places that it only works with the TS-1000 and ZX81, but it loaded and ran fine on my TS-1500 as well.
