Aster folded. Most of the engineers who designed the hardware and software of the Aster went on to design hardware and software for the (then new) MSX system for a company called "Micro Technology b.v.". Unreleased add ons To enhance and modernize the Aster CT-80 the company also designed three alternative video display adapters to supplement or replace the TRS-80 compatible video card, (due to the modular nature of the Aster it was simply a matter of changing the video card, and/or CPU card to upgrade the system). A very High resolution monochrome video card with blitter and hardware text line and arc drawing capability, was designed for CAD applications, based on the NEC μPD7220 chip designed for graphic terminals, but was also used by some personal computers like the DEC Rainbow, and notably also for the Tulip System I. A colour video card with sprite capability based on the same video chip (the TMS9918) as the TI-99/4 and MSX computers, designed for gaming, and more creative and colorful educational software. A working prototype of this card was finished. A replacement card for the original TRS-80 compatible video card, software compatible to the original one, but with added color and very high resolution capabilities. was also on the drawing board. Based on a newer, slightly more flexible, version of the Asters original Motorola MC6845 video chip, the Rockwell 6545, it worked by adding a new video mode, one with the ability to reprogram an extended, (2048 characters instead of 256 characters) version of the character set, supported by an extended character memory of the video card that did not use one (8 bit) byte per character, but an 11 bit "word", so it could address each one of the available 2048 unique programmable characters. This meant it could provide a separate programmable character for all of the 1024 (64x16) or 2000 (80x25) characters on the screen. By filling the character pointer memory with values from zero to 1999 this essentially turned the text mode display into a very high resolution graphics mode, with the "font memory", acting as the high resolution Raster graphics video memory. Because the characters were 8 x 12 pixels this meant that video resolutions of 512 x 192 pixels (in 64x16 character mode), or 640 x 300 pixels (in 80x25 character mode) were created, which was quite high for the time. The "double width" mode of
