The Job Tracking System in BASIC

It was time to put my new SBASIC tool to good use. Bob wanted a new tracking system to replace the old TRS-80 one. We decided to use one of the Kaypro II machines for this. I'm a little fuzzy on whether Bob started this one and handed it off to me, or if I was the developer from the get-go.  Regardless, this project was a showcase for what could be done with the BASIC programming language.

This was a pretty easy application to build. There were a dozen or so departments on the factory floor. Each time a new job was ordered there were some essentials entered like job #, customer name, board type, due date, etc. and these were just stored in a simple random access file. Several times a day a young lady from Brazil named Danusa would make rounds collecting information about jobs and where they were in factory. Then she would come back and enter this information. Status reports would get printed out.

C.F.C. specialized in quick turnaround orders. Anything we could do to improve information about important rush orders was critical. A more timely tracking system was in our sights. We took one of the Tandy Model 100 portables and bought a barcode wand for it.  A data collection program for it was written in BASIC.  This would be used to collect the locations of all the jobs. I wrote a program in the tracking application for printing 3 of 9 bar code on label stock using an Epson compatible dot matrix printer. These had job numbers on them and we stuck them on the job bill of materials sheets that went with each order. Then we printed large bar codes for each department.

So now all Danusa had to do was go to a department, scan the bar code on the department sign, and then go to each bill of materials sheet and scan in the job number bar code. Then she would repeat this with each department. When this was done (and it was a lot faster than using a pen and clipboard) all she had to do was come back and we would read the information into the Kaypro II using an RS-232 cable and we would just suck that information into the tracking system and print the reports.

It really stands out to me that this sort of very useful application programming was easily achievable by a high school graduate with a knowledge of BASIC.  For a good while we used this system to expedite manufacturing.   End users used to do this kind of thing a lot more back then and I'm sure that Bob could easily have written this himself if he were so inclined and it he weren't so busy running the company. People should take more interest in programming because it's fun, it teaches important thinking skills and even untrained programmers can accomplish real productivity enhancements.

A Cornucopia of Computers

So I joined the engineering group at C.F.C. Our job was to write and debug CNC programs for the Excellon drilling and routing machines. Most of the programs were written using WordStar on Osborne-1 and Kaypro CP/M machines. We did not use hard drives to do this work, and the final medium of storage was punched paper tape. Yes, really! That was the format the machines used, and we had a storage library for keeping the tapes.

There was one Macintosh in engineering for special purposes, but here again I never used it.

There was a TRS-80 used for managing job tracking in the factory. It had the standard silver expansion box and three floppy drives.

Accounting had an Epson PC clone (or was it a Leading Edge Model D?), and there were a couple of Tandy Model 100 laptops that look like Alan Kay's Dynabook prototype.

Things were about to get interesting.

Early networks

When I started in high school at Xavarian Brothers High School in Westwood, Mass. they had an early example of a network. It amounted to a shared hard drive between four TRS-80 Model 3 computers (or maybe they were Model 4s). There were also Epson MX-70 printers.

I didn't actually take the programming class, which was only available for juniors and seniors, but my math class was in the classroom where the computers were, and I would sometimes write little programs for them in the minutes before or after class.

I'm not sure if the hard drive was manually or automatically switched, or if these computers ran a real disk operating system. I don't remember the computers having floppy drives, and it seems unlikely that they had networking code built into the power-up ROMs; just BASIC.

Perhaps someone else would be eager to comment on this?

My First Programming Job

As well as I can remember (this would have been 1981) I met Patrick A. Alessi when I was 14 years old at NEECO. He was there purchasing an Apple II+ and an Epson MX-100 printer, and he told the sales guy there he needed a programmer to work on some business software. They pointed across the store at me. He told me later that he said, "Who, him? He's just a kid!" They introduced us to each other.

Turns out I knew his son Michael from playing kickball at the park down the street. Mr. Alessi lived a mere 4 blocks away from me, which was the perfect distance. So I began visiting his place. As first we just played pool and experimented with his new Apple II+, and Mr. Alessi made no apologies about sharing his political opinions while smoking different kinds of pipe tobacco.

Since my friend Richard had an Apple II computer I got some games from him, and I made a joystick for the computer out of parts I bought at Radio Shack. I reused the case from an RC car's remote control. I cut out the steering wheel and replaced it with a dual-potentiometer joystick. It was ugly, but I saved some money. ;-)

Mr. Alessi was interested in creating some trend following inventory management software, and he talked a lot about this. Eventually we would begin to write this software, and do a lot of other things as well. This was not going to make me much money in the short run, but I couldn't have asked for a better opportunity to learn.
