I just starting getting into the TRS-80 (model I/III/4).  I’ve got an emulator up and running, but I’m interested in REAL hardware.


I’m looking at the following: https://portland.craigslist.org/clc/ele/d/lebanon-vintage-radio-shack-tandy-trs/7326846968.html


What does the NO SYS error mean?  I’ve tried Googling it and looking at various lists of error messages, but I can’t find that one.  Is it really just looking for a system disk?  I thought they started with BASIC if there was no disk found.

 

Thanks!

It means the computer was booted with a data diskette inserted.  That's a diskette that doesn't have the operating system installed but does have a boot block that prints "NO SYS".

 

It's a good sign that the floppy drive works.

If you have a Model 1/3/4 with a disk drive - by default it will attempt to boot off drive 0.

If you have a data disk in drive 0 - you'll get the NO SYS error message or equivalent.  It may vary from data disk to data disk depending on the DOS that was used to create it.

 

You can boot to BASIC by holding down whatever key in the emulator corresponds to BREAK and then reseting the emulator.

A Tandy 3 :-o

 

That's a very rare version and one heck of a way to enter the hobby.  It won't last long at that price.

 

Note: It's just a Model III, but sought after for the looks.
