The 68000 has a 16-bit external data bus so must transfer 32 bits of data in two consecutive steps, a technique called multiplexing: all this is transparent to the software, which was 32-bit from the beginning.
Although the hardware is limited to four separate sound channels, software such as OctaMED uses software mixing to allow eight or more virtual channels, and it was possible for software to mix two hardware channels to achieve a single 14-bit resolution channel by playing with the volumes of the channels in such a way that one of the source channels contributes the most significant bits and the other the least.
A retargetable sound API called AHI was developed allowing these cards to be used transparently by the OS and software.

The first used the same graphics processor as the BBC Micro in mode 7 — the SAA5050 — but used software to ensure that it was fed with the correct graphics data.
A software ROM was still supplied, but this did no more than expand the hardware ROM so that it knew mode 7 now existed and was able to switch into it.

It also had a built in speaker which was compatible with such games software.
A third mode was entered with a special boot floppy which turned the Aster into a Videotex terminal with a 40x25 display and a Videotex character set, The software used the built in RS232 interface of the Aster to control a modem through which it could contact a Prestel service provider.
Another important demand was that the computers could be used in a network ( Aster developed special software and hardware for that ).
Later however the Government turned around and gave 50 % of the order to Philips and their P2000 homecomputer even though the P2000 did not meet all the technical demands, was made in Austria and did not have network hard nor software.
