GDOS-80 is a software tools developed for all grifo® industrial cards based on the wide Z80 family of microprocessor.
This software tools allows programmation of these cards through high level environments that doesn't require a closely knowledge of the used hardware. With GDOS-80, the user exployes high level programming languages and many other resources, not available in other different software tools. It is possible to develop, debug and install any kind of user programs obtaining complete applications in a fast and confortable way.
GDOS-80 is a simple and efficient operating system for industrial application. It derives from famous Digital Research CP/M operating system and it has similar command and similar programming mode. For those users that don't know the CP/M, these modes can be compared to the MS-DOS famous ones, in fact GDOS-80 preserves its philosophy of use.
As well as all the operating systems, GDOS-80 interfaces hardware to the user, so this one never must develop low level firmware but he can directly use hardware with high level instructions, commands and languages. The power of GDOS-80 is the result of two features: the possibility to choose between many programming environments (theoretically all CP/M softwares) and the possibility to use the hardware resource of an external personal computer to simplify the develop and debug phases.
For example GDOS-80 manages the following hardware resource: serial lines, printers, mass memory devices, user interfaces that can whole be used by programmers through simple instrunctions of the selected programming language. Normally the operating system uses a little space of memory and it shares the use of one serial line. If this features are not acceptable, there are some hardware solution that solve the problem.
GDOS-80 is composed by some subsistems that create a
confortable develop environment provided of: notes, guides, on
line help, examples, etc.
The GDOS-80 is composed by software on disks, a user manual and a memory device (EPROM or FLASH EPROM) for the used card.
Z80 based control card
It is the electronic card that belong to grifo® industrial set, based on Z80, Z180, HD64180 and compatible microprocessors, as:
Independently from the application to develop, the target card must be provided of:
A personal computer provided of:
An hard disk is not necessary but recomended to speed all the
files management operations.
This is the software that must be used to write and test the application program to develop. In details the programming software is one of the following programming languages :
The GDOS-80, when combined with a programming software, can be used to develop embedded code for the selected control card. It has many features that are below summarized
To satisfy all the different requirements of the customers, the GDOS 80 is available in the following versions:
Operating system for target card GPC® xxx on EPROM.
Operating system for target card GPC® xxx on FLASH EPROM.
GDOS xxx MCI and FGDOS xxx MCI
Operating system for target card GPC® xxx on EPROM or FLASH EPROM, with memory card RAM disk management, through MCI 64.
FGD xxx and FGD xxx MCI
FLASH EPROM for target card GPC® xxx with the operating system saved on its first sector.
