February 17, 2010 – For Those with a 4P



As far as we know, the Model 4P had only 2 BOOT ROM’s, v1(15) and v1(16), the former being dated October 11, 1983 and the latter being released 7 days later.

Although technically the v1(15) ROM would have been in every Model 4P released before October 18, 1983, the 7 day window leads us to believe that it would have applied only to very very very early models. However, there is no known dump of the v1(15) ROM.


If you have a Model 4P and are interested in helping, turn it on and hold down the “V” key. After a few seconds a message which reads “Boot ROM Version is ___”. If you have a 4P where it is 1(15), and are willing to dump the ROM (instructions will be provided), please send me an email.

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
