AMA (call detail) tapes from small phone companies and long distance resellers are processed into subscriber bills and statistical reports.
Not all of the details of this application were made clear to us. Apparently the HUD department of the US government makes available tapes of people who are entitled to mortgage insurance premium refunds. The task is to match up that database with name and address databases in an effort to locate those to whom refunds are due.
US Census data is transferred from tape to disk, then processed overnight by proprietary statistical analysis routines, and the results are sold to clients in the insurance business.
Keypunch service bureaus provide "cottage industry" employees with PC clones. Each morning, data to be keypunched is delivered to the home workers, at the end of the day diskettes with the keypunched data are collected. The files on the diskettes are transferred to tape at the main office.
Computer aided design programs, now common on high speed PC's, produce drawing files on disk. The disk files are transferred to tape for photo plotting on systems made by Gerber, Computervision and others.
In this application, Data General minicomputers are being replaced by PC's. Electrovalue's FX program reads the tapes, strips off the extraneous (Data General RDOS) bytes at the end of each tape block and writes the remaining data to disk.
Tick tapes are analyzed by stock market and commodity traders in hopes of predicting trading trends.
The IRS is pleased to receive data on magnetic tape, for example W2 and 1099 forms. IRS rules require submission on magnetic media if the number of forms exceeds certain limits.

The Federal Aviation Administration has hired a private contractor to distribute copies of over a dozen interesting databases at minimal cost. Send these guys a tape and a few dollars and receive 49 megabytes of aircraft registrations by return UPS. Or 77 megabytes of pilot license information. Use our software to extract the fields of interest and join the group of customers who are making money with this data.

Tapes with cardholder names and numbers are read by a PC which controls a credit card manufacturing machine.
Technology has advanced while the economy has declined. This situation has added fuel to the popularity of downsizing mainframe applications to the PC arena. Accompanying this transition has been the frequent need to continue reading and writing 9-track and 3480/90/90e tapes on the PC.
It can cost from $14,000, to upwards of $31,000, to add a tape drive directly to an IBM AS/400, System 34, System 36 or similar midsize computer. Those in the know purchase a PC 9-track 3480/90/90e drive. The PC communicates with the midrange computer using an IBM package called PC SUPPORT.
These customers use a unique Electrovalue software feature (KEYLIST MATCHING), which was added at a customer's request. Aircraft, motorcycle and automotive parts businesses get massive semiannual parts list tapes from the factory and automatically import only those records where the part number can be found in a locally maintained disk file of parts which they stock locally.
Group uses the inverse of the above KEYLIST MATCHING feature, the ability to reject records from tape when the potential donor's name can be found in a locally maintained disk file containing the names of people from whom they do not wish to solicit funds. They process the data with "THE RAISER'S EDGE" software.
use a larger proportion of Electrovalue's software features than the usual customer. Just some of the features they find useful are the ability to simultaneously select records and fields, rearrange the order of fields, strip off trailing blanks, add any literal text as field delimiters and transfer the results directly to floppies without splitting records from one floppy to another. Our myriad features allow them to fill the floppies with just the data their customers need, in a format friendly to the particular intended use. The data manipulation scenario used by each customer is maintained in reusable disk files called CONTROL FILES. Running a similar job on a future date simply requires the service bureau personnel to invoke the appropriate CONTROL FILE during the tape-to-diskette transfer.
A lawyer who earns his living by demanding that debts be paid gets tapes from creditors and duns the deadbeats with computer generated mailings.
A large commercial printer uses our software on the PC to quickly and economically check the quality, format and contents of mainframe tapes before they are sent along as input to massive printing jobs.
Several customers import all kinds of data to the PC and pre-process it in order to publish articles, directories and CD ROMs. In some cases they write tapes which are read by large (e.g. Xerox) printers and photo-typesetters.
Data tapes with radio listener and TV viewer data are processed statistically on the PC so the client can advise potential advertisers on the estimated effectiveness of their program choices.
These tapes are 9 track tapes written in a special format. Some of our customers who process mailing lists for lettershops write a program or use a commercially available program to convert their mailing lists into a format that the ink jet machine uses. Then, they use our software to write the file to tape, thus creating an ink jet tape.
There is a myriad of customer applications that use ElectroValue tape packages. We have complete drive, controller card and software packages. If you already have software or are looking for a drive alone, we can sell you a drive.
