Important notes :
- The ROM images of the PC-1500A are included in the emulator, available here for educational purpose only, since this computer is now obsolete. If you own a Copyright on this material and don't want it to be available from this site, please inform me and I will remove it immediately.
- Before typing a program, you need to perform a NEW 0 command, otherwise the emulator will jam.
- In PRO mode, the arrow keys used to
move in the listing aren't functionnal :
You need to perform a LIST
LineNumber command, then it is possible to use the arrow keys.
- Several consecutive breaks are not managed.
- The 4 arrow keys are not auto-repeat.
- The content of the memory is backuped
in the pc1500a.mem file.
If this file is deleted, the
emulator will perfom a reset of the PC-1500 at starting.
- The Auto Power Off is functionnal !
On a fast computer, in maximum fréquency mode, the PC-1500 auto powers
off after few seconds ...
- The emulator was tested under Windows 95,
98, NT4, 2000, and XP.
The recommanded minimum display resolution is
1024x768 using 65536 colors.
- In trace mode, the trace file is named Traces,
WARNING it's size grows very very fast !
(it
can reach Gigabytes ...)
- We can't be involved in any damages consequently of the use of this software.
