October 12, 2010 – Possibly Found v1.0 and v1.1 ROMs


A site visitor has indicated that he believes he has a Model I which has the v1.0 and the v1.1 ROMs and intends to either dump them to cassette or read them in an EPROM reader. Of course, if anyone finds they have v1.0 or v1.1 ROMs, please let me know. ROMs can be dumped to disk as follows:

   10 PC=0 : IR=0
   20 OPEN "O",1,"NEWROM/ROM:0"
   30 FOR X = 0 TO &H2FFF
   40 PRINT #1,CHR$(PEEK(X)); : IR=IR+1
   50 IF IR = 614 THEN IR = 0: PC=PC+5: PRINT PC"% ...";
   60 NEXT X
   70 PRINT "DONE!":PRINT
   80 CLOSE

It takes about 1/2 hour to run (which is why I coded in 5% increment status updates)

February 6, 2009 – Site Updates and Updated Emulators



As I continue to explore WordPress, I am toying with the idea of moving more of the site over. In connection with this transition, I have been reworking the emulator page to clean up HTML errors and make it more WordPress friendly.

In doing so, I also verified the links and have realized that a number of emulators have been updated. These include:

  • HT 1080/Z v1.6, updated on Sep. 17, 2007
  • VCC v1.40 Installer, updated on Jan. 3, 2008
  • MC-10 Emulator v0.73c, updated on May, 2008
  • Multi Emulator Super System (Binary) v1.29 updated on Jan. 6, 2008
  • Virtual T v1.3 updated on Sep. 25, 2008

    January 25, 2008 – New Version of TRS32 Released


    Matthew Reed has released an update to his PHENOMENAL Windows Compatible TRS-80 Model 1/3/4 emulator.

    The updated version 1.18 can be downloaded here or from his site.

    If you are looking for a Windows based emulator, this is the one to register (which I strongly encourage you to do … and NO, I do not see a penny from this venture or recommendation).

    July 3, 2007 – Updated Emulator, ReadDisk, and More!!

    BIG NEWS! Matthew Reed has updated his Windows emulator to v1.16 and his fantastic READDISK utility to v2.1, all under a brand new domain name of www.trs-80emulators.com

    I have updated all the links here, or you can go directly to his web site and download the software there.

    There have been many bug fixes and tweaks, including:

  • Revamping the keyboard handling to work better with CP/M
  • Autostarting now resets the pause state; and
  • TRSDOS 6.01.00 now autostarts.

    Registration of the emulator (I get NO share or incentive for your registrations) provides you with:

  • Multiple types of high-resolution graphics boards
  • Orchestra 85/90 music generation
  • Several types of real-time-clocks
  • Up to 1Mb of additional memory (in Model 4 mode)
  • Virtual hard drive support; and
  • Epson FX-80 compatible printer emulation

    This is the emulator I use in maintaining the site.
