Profile of Setu arround Computers.

- Realtime mini Kernel -
I wrote a small realtime kernel for PACE, an 16 bit micro processor
from National Semiconductor.
	- Interrupt control
	- Multi process control (process switching).
	- scheduling of process
- Data Aquision System
	- I was woring with digital and analog engineers.
	  I was only programmer then I could do ay kind of software design.
	  To make something fun, I wrote a realtime kernel.
	- it has Open reel tape drive and ananlog channels 16 to ?? I forgot.
	- 
- PAL programing system.
	- based on PAL (very subset of pascal)
- Pascal subset compiler
	- written in PLZ/SYS running on Zilog's box and OS.
- LISP interpreter
	- written in Z-80 assember running on Zilog's box and OS.
- Assember and tools for PACE
	- written in Fortran-77 running on VAX/VMS
	- I would like to use C for it but C compiler for VMS was so expensive.
	- Assembler for PACE was simple. So, I used Fortran-77.
	- include program loader, data generator for EPROM writer.
	- I was developper and user. it was so fun.
- Floppy disc file system
	- something like FAT. It was my mistake to use that design.
- Another Floppy disc file system
	- did not finish but Design only
- File system on Hard disk
	- this was for Fax which has Harddisc for both program and data.
	- Fax box has dial up networking.
	- written in C and 8086 assembler.
- Graphic Libraries for 2D and 3D.
	I forgot what I have done.
	part of Seismic data processing system.
	VAX-11/750 VMS
- Admin of VAX/VMS and UNIX bsd4.1/2
	- this was fun. I was writing many utilities for system control...
	- But busy for real programming job too.
- another LISP Interpreter
	- for Motrola 6809 MPU.
	- I did not finish. just for my fun.
- reverse engneering for OS9 operating system
	- It was well designed system. coding was clean.
	- onece I was reverse engeneered an module of MS-DOS (Serial driver)
	  to improve. It was nothing fun. ugry codes.
= I became a indepandent programmer.
- fax machine
	- 8086 assembler
	- hard disk file system
- CD / Laser disc writer (1982) - sony
	- MC68000 assembler
	- 40,000 lines
	- control 10 or more periferal machine connected via
		- serial, paralel, GPIB bus
		- video (few types), audio (few types), etc
	- control cutting machine (controled by mini-computer)
= I made a company with other 2 friends (Unitie Software Brains Co.,ltd)
- financial software
	- for my company
	- Dbase2 database software
- Data gathering software
	- 8086 with PLM language
	- running on realtime OS (I forgot the name)
	- I did design and gave to someone.
- Map information system for Electoric board
	- I did comunication part with Database
	- C language
	- VAX/Ultrix (UNIX)
	- TCP/IP based communication (server/client)
	- I don't remember which database server was it.
- Controlling big shaker for 1/10 model of Nuclea plant.
	- Basic :_:
- User Interface library for Basic
	- this is small program but it made programming very eazy.
- (ne?engine) User Interface library for C + MS-DOS
	- actually it was character base windowing system.
	- written by C but it was Objective design
	- it has exception handling extension like C++ or Lisp
	- quite big like 40,000 lines or more (I forgot)
- (ah!handler) like Norton Commandar
	- I should share with GPL license but I did not :_:
- Broadcasting Control System for Cable TV station (with Sony)
	- C language on MS-DOS
	- multitasking with my own task controller
		- but pass control in the tail of each...
	- a lot of lines (I forgot. Let's say 30,000)
	- it was hard job without time. I almost got sick.
	- it controls 32 or more channels of TV.
	- each channel has its own controller box
		- it was connected something like LAN like MacTalk
		- rs422(?) serial line shared with multiple box
		- control protocol was designed based on SCSI :)
- Data aquisition and graphical display
	- UNIX / C language
	- window system but not X. Toshiba original windowing system.
	- process communication with tcp/ip socket. server/client.
- Some small jobs on UNIX / C / X-windows / TCPIP
