not run well on a TRS-80. So they decided to design a TRS-80 and CP/M software-compatible computer system, which (following the lead of Apple Computer) they decided to name after a "typical Dutch flower". So they called it the Aster CT-80 (CP/M/Tandy-1980). Why they went with Aster, and not the more well known Tulip is unknown, perhaps they thought it would be to presumptuous, or perhaps the fact that "Aster" is also a Dutch girls' name has something to do with it. Remarkably "Aster" was also the name given to a Dutch Supercomputer much later, in 2002. The first version of the Aster consisted of four "Eurocards", one Z80 CPU card with 64 KB memory, one Motorola MC6845-based video card, one double density floppy disk controller card and one "keyboard/RS-232/cassette interface" card. Plus a "backplane card", (which connected all the other cards) and a keyboard. And was intended for hobbyists, to be sold as a kit consisting of the parts and the PCB's for the computer and attached keyboard. After selling a few kits, MCP became convinced there was a much bigger market for an improved model sold as a completed working system. However the original kit version lacked many features that prevented its use as a serious computer system. Because the original designer had left the company another employee completely redesigned most of the system, (adding a display snow remover circuit, true 80/64 column text mode support, (with different size letters for TRS-80 and CP/M mode, so that in TRS-80 mode the full screen was also used, not just a 64×16 portion of the 80×25 screen) with an improved font set (adding "gray scale" version of the TRS-80 mozaik graphics and many special PETSCII like characters), and a more flexible and reliable floppy disk controller and keyboard interface plus many other small improvements), also an enclosure was developed for the main computer system, (in the form of a 19-inch rack for the Eurocards) and for two floppy disk drives and the power supply. A software engineer was hired to write the special "dual boot mode" BIOS and the special CP/M BIOS. The "dual boot mode" BIOS actually discovered whether a TRS-DOS, or Aster CP/M disk was placed in the drive, and would, depending on the type of disk, reorganise the internal memory architecture of the system, to either be 100% TRS-80 compatible or optimally support CP/M, with as much
