TRS32 1.25 - Tandy Radio Shack Emulator

TRS32 stworzony przez Matthew Reed jest komercyjnym emulatoremu mikrokomputerów Tandy Radio Shack, którego pierwsze modele rozpoczęto sprzedawać w lata '70. Niestety nawet jak dla mnie sama platforma jest na tyle egzotyczna, że trudno mi nawet napisać coś konkretnego o samym emulatorze:)
TRS32 kosztuje 69 dolarów, co jak można wyczytać na wikipedii jest jedną dziesiąta, za którą można było kupić pierwszy model tego komputera w roku 1977, przypadek?;)

This release includes two bug fixes and one new feature:

• William Bosacker sent me a NEWDOS/80 boot disk that kept generating “Device not available” errors instead of displaying a directory. I tracked the problem down to a one bit error in the emulated interrupt status ports. This qualifies as one of the most obscure emulation bugs I have ever found; it would occur only one time when reading that one port at that one instant.

• Ira Goldklang sent me a Model III boot disk that was being identified as Model 4 by the “Autostart” feature. Although the disk still worked (it just ran in Model III mode), I added recognition of this unusual boot sector to the autostart routine.

• I also added a new feature suggested by Ira Goldklang. Now hovering the mouse cursor over the floppy drive indicator light in the status bar will display the current drive status and position. This makes it easier to determine if a boot disk is loading or just cycling endlessly.
