means of drawing. The last two generations of NewBrain ROMs included additional graphics commands — ROM 1.9 had two more commands, and ROM 2.0 some more. But to ensure compatibility little software would use these additional commands. The programmers were working on version 2.2 as well as versions for different keyboards, including Greek and Swedish as well as French and German. Grundy had been considering offering the Series 2 ROMs to existing users. This required the existing soldered in ROMs to be removed from the circuit board and a socket soldered in. The tight fit and labour cost was high on this retrofitting, and the failure of the company in 1983 meant that users were never aware that this was being considered. The version of BASIC was an extended version of ANSI BASIC, the facilities of which were similar to those in Microsoft BASIC. The graphics package included commands that could draw dots, lines, arcs, filled-in areas and annotated axes. Grundy offered a 'Software Technical Manual'. This manual documented various routines that could be called in the ROM and the calling parameters. It was left to the NewBrain user groups to publish the details of how to access these routines through the indirect call. (A low-memory address was called with the relevant routine parameters, and this address would call the ROM-specific location of a jump table which, in turn, then called the final routine.) Even screen access required this indirect use, as the screen location would change as new input and output streams were created, including high-resolution (for the time) graphic streams. Memory maps and other technical information were included in numerous technical notes which were supplied to dealers and owners free of charge. The Technical Manual had a retail price of £50. HiSoft produced NewBrain versions of their Pascal compiler and editor. A number of CP/M applications were converted to using the NewBrain's CP/M terminal and made available on NewBrain 5.25" and 3.5" formatted diskettes. These included Z80 Assemblers and debuggers, Pro Pascal and Pro Fortran, TCL Pascal, dBase II, Wordstar 3.3, Peachtree Accounting applications, the Superfile database and CP/M versions of Hisoft Pascal, Modula-2, Z80 Assembler and text editor. Many third party software houses (e.g. IEL, MicroMart, Black Knight Computers) provided independent software for the NewBrain, which was supplied to users such as the British Ministry of Defence, and Cambridge University.
