  • A Break Through DOS for the TS-2068
    MAX DOS: combining Oliger DOS and Larken DOS.
  • Extra Memory
    A TS-2068 that has twenty times the maximum capacity of a IBM XT! Do pictures and proof schematics lie? An interesting article by Mr. Charles Bothier sets the technical basis for our cottage industry to provide more memory expansion hardware.
  • The New Oliger V2-52 EPROM
    The latest Oliger DOS EPROM includes ERASE / (file name), RESTORE / (old file name to new file name), RESTORE /”new disk name”, RESTORE /(used alone to re-initialize to default parameters), VERIFY /(file name) to check the file for errors, COPY/ copies screen to printer, MERGE /(program name), SAVE //(Save without warning ~ that file
  • Letters
    Letters from Ray Norton about BASICare modules.
  • MAX DOS: A Study of DUAL DOS in the TS-2068
    For several weeks UPDATE has been testing two simultaneous disk operating systems in the TS-2068: the Oliger SAFE DOS and the Larken DOS. The hardware hook-up is the full “two board” Oliger system and the Larken LKDOS cartridge in the dock port. Extensive operation with the combination has revealed an almost complete compatibility between the
  • CTM Magazine Quits
    Chet Lambert, owner/publisher of CTM Magazine, announced in the June issue that he is quitting. CTM supported amateur radio operators and contributed to the development of packet telecommunications.

  • Dense Pack Basic, and the use of Logical Operators
    There has been a considerable amount of questions and interest about Dense Pack programming techniques andt the use of Boolean logic. This article written in 1983 by Sharon Aker merges nicely with my feeble attempts to explain the use of Boolean Logic in Basic programming.
  • QL Characteristics
    About half of the subscribers to UP-DATE are owners of both the TS-2068 and tlie Sinclair QL, the latest member of the Orphan Computer family. Comments received about the QL range from pure disgust to enthusiastic praise. But there is one common denominator amongst the QL owners and that is a desire to learn how
  • FDD Express: More Letters
    Letters from Bob Orrfelt about the FDD technical manual he was writing; Jack Dohany about Zebra FDD system; Dennis Bryant about Amdek DXY-100 Plotter and sound; Tom Dunlop about moving Profile 2068 to disk.
  • TS-2068 with Unlimited RAM capability
    Schematics and machine code to expand the 2068 RAM with port buffer, clock/calendar, 56K or 64K, expansion bank controller and proper address decoding for EXROM.
  • Larken Disk Doctor
    This utility will be found useful in the inspection, analysis, and correction of errors on disks used on the Larken disk drive system. This utility is designed for use with the Larken 350K per disk I/F board.
  • The Budget Software, Part II
    This software began in the April issue. Some repetition is included for convenience of reading. There are several ways of attacking this group of programs. You can key in the listings, which will give you a operating BUDGET and SPREADSHEET program “in basic”.
  • MS-TAS Documentation: A Tutor in Basic Programming Techniques
    Program to view MSCRIPT and TASWORD files.
  • Utilities "INIT" and "Cclear Code"
    The “INIT” utilities for the three Disk Operating Systems are slightly different. Each listing may be used to pick up another little twist for another DOS.
  • Software Review: Money Machine II
    For those unfortunate ones who are able to observe Vanna infrequently or not at all, but are nevertheless equipped with a T/S 2068, there remains the option of MONEY MACHINE II. This option not only permits discretionary observation of Miss Banna Brite (as shapely an assembly of pixels as one could wish for), but also
  • The "PEEK VARS" Utility
    The PEEK VARS utility is designed to be MERGED to a Basic program either under construction, or one that is being modified. Use it as a “dangling sub-routine” to be consulted when facts about the System Variables are needed. ยซGO TO 9000ยป gets a screen print of the System Variables that may be needed for
  • Addendum to Article in January Update "Dock Bank Memory, 20 Cents"
    Corrected diagram.
  • The July/April Issue Disk Consolidated into One
    The July and April Issue Diskettes have been consolodated into one giant assemblage of programs and utilities. The consolodation was necessary because the Budget program, by Bob Mitchell, was split between the two issues. I have not ever seen such a combined useful and educational works presented in a computer magazine.
