TurboDOS
Parts of this topic may be machine translated.
TurboDOS is a partially CP/M-compatible operating system for Zilog Z80-compatible and Intel 8086 processors developed by Software 2000 Inc.
It was released around 1982 for S100 bus-based systems such as the NorthStar Horizon and the Commercial Systems CSI-50, CSI-75, SCI-100, and CSI-150 multiprocessor series.
Its core is modular, while the generation of the operating system is based on the relocation, linking, boot program "gen".
In Czechoslovakia, TurboDOS was used for the TNS-DOS system of JZD Slušovice for computers TNS ST, TNS SC, TNS GC, TNS MC, and TNS HC.
Version
TurboDOS was introduced in the following versions: 1.00-1.16, 1.20-1.22, 1.30, 1.40-1.43. The last version in each range was always a "stable" debug version.
- 1.00 (up to 1.16) were the earliest versions of TurboDOS, created and released at a time when MP/M did not work and MP/M-II did not exist. As a result, a proprietary form of file locking via the $.LOK pseudo-file was used and record locking was not possible.
- 1.16
- 1.20 dated 09/29/1982, this was the first version compatible with MP/M in terms of file and record locking. It still used extended BDOS function numbers for TurboDOS-specific functions, and many newer CP/M and MP/M programs do not work because of it.
- 1.22
- 1.30 dated 03.01.1983, this version removed the BDOS/TurboDOS feature conflict, greatly improved overall performance, and introduced the ability to use 16-bit slave systems.
- 1.40 introduced 16-bit master systems, which enabled a significant jump in performance and the ability to interface with IBM PCs.
- 1.41 with the date 04.01.1984
- 1.42 dated 01/02/1985 greatly improved the networking capabilities of version 1.41 and added several new features.
- 1.43 dated 07.01.1986, the last known version. It again improved network capabilities, added additional functions, and increased the number of concurrently open files from several hundred to thousands, which made it possible to increase the performance of database programs.
