LNW80 Various Topics Page

Here I collect various snippets of information about LNW80 computers:

• John Webb sent me this description of an LNW80 application in the early 80's. :

  I think I may have had the first "desk top publishing" system that consisted of an LNW80 attached to a Xerox 2700 Laser Printer. The laser printer cost $24,000.00 back then and could have 4 font cartridges installed in it at one time. I used a parallel interface and Newscript word processing program and NewDos as the O/S. I had already interfaced the LNW80 to a phototypesetter and set type with it. It worked great and saved me a fortune on film. I cannot remember what year I did this but I do know the LNW80 II was not out yet.

  I sold 2 LNW80's / XEROX 2700 laser printer combinations to 2 different companies. One company printed a "Blue Book" on used aircraft prices and they produced a new copy every month. They had been using an IBM MT/ST typewriter. They actually keyed in a complete book each month before I sold them the LNW80. The other company was a law firm that did "legal printing". They produced General Partnership documents primarily for Oil & Gas exploration partnerships.

  I never got another micro until MSDOS seemed to start dominating the PC market. Then I bought an "IBM clone" and eventually my LNW80 was retired. I loved Newscript (you could have 2 different printer drivers loaded at the same time and it supported proportional spacing) and I used the LNW80 for quite a while just because of Newscript's capabilities. WordStar on CP/M machines was crap and when Wordperfect finally came out for MSDOS I was finally able to let my LNW80 go.

  There were probably many...
  
  I have one that I bought in '84, from
  General Northern Microcomputers Ltd. in England
  My kit was for the Video Genie but They also had a version for the real
  TRS-80 model I.
  
  The kit replaces the original 4116 chips with 4564's and changes the
  chipselect and addresses to fit.
  
  It used port 127 for "bankswitching", 0=48K mode normal, 1=60K replace ROM
  with RAM too and 3=64K whole address space to RAM.

These are the modifications to my own LNW.

• Expanding graphics memory to four pages
• Documentation on the Dutch Selector board. A LNW CP/M compatible upgrade with extendend bankswitching. Designed by Rence Roozendaal of the NO-division (Noord Oost/North East) of the dutch TRS80 user society.
