[Coco] So is this a G board?

[Bruce W. Calkins]

Referring to old memories; I have two "F"/285 board grey cased CoCo 1s.  the 
early ones often locked up and needed a cold restart each time.  My second 
"F"/285 had the "fix" and was OK with most software, but I seem to recall it 
had issues with some OS-9 software.  My fix at the time was to use a CoCo 2B 
at that station.  IIRC; both "F"/285 board CoCo 1s are somewhere in my 
midden heap, but available time to root them out and "play" with them is in 
short supply.

Further recollections; My "E" board CoCo was rock solid in spite of the 
abuse I heaped upon it as I learned.  CoCo 2s and 3s tended to be solid 
performers as well.  The early "F"/285 boards had some problems and I am not 
convinced the "fix" addressed them all.

FWIW; I have possessed almost every version of CoCo from the "D" board 
through the CoCo 3 except the TDP-100 accumulating almost 4 dozen CoCos 
before I moved in 2004.  I shed myself of a few of them before and since 
moving.  I have seen two samples of the rare 64k satellite board for the 
CoCo 2A & B variants.  The only CoCos I had any significant problems with 
were the "F"/285 board units.

Luis,
Something sounds very borderline/defective in this machine.

I don't have a scope but I friend of mine does. So if I need I can use it.

The behaviour of the sIDE is erratic, sometimes is hangs right after
displaying HDBDOS 1.1D... with some garbage, other times it will pass the
boot (showing the HDBDOS 1.1 LBDA MODE) and a Ok but accessing the CF will
give me I/O error. Sometimes i will get the boot and a ?FN ERROR (trying to
load AUTOEXEC.BAS ?).
