A89: Re: difference between hw1 and hw2
Hey, i got my 89 when it first came out. back
in the day. thus its a hw1... for the past few months i have been away and
havent even been to ticalc or any ti related site. i came back a few days ago
(now a regular) and noticed something about hw2. i know enough to know that
everyone is complaining about this. ive been looking for info, but to no
avail. i just want to know a bit about the differences, why everyone hates
hw2, if i should upgrade my calc, etc... i just dont know much about this and
would like to get to know some more :)
thanks.

First, here are the advantages of the HW2 :
_ the processor runs at 12 Mhz instead of 10.
_ when you install ams 2.03 on a HW2 calc, the
archive memory reaches a size of about 700 ko (HW1 calcs having only less
than 400 ko). However, a patch was recently released, allowing HW1 calcs to
access this extra memory
Now here are the flaws :
_ The lcd screen works differently, the consequence is that
grayscales are harder to produce. While this problem is now solved, all programs
used to work in B&W only on HW2 calcs for a too long time.
_ When you install ams 2.03 on a HW2 calc, a hardware
protection is activated, that prevent you to run assembly programs larger than 8
ko. Again, this problem took a long time before being solved.
Now, we can almost say there are no more problems with
HW2. Wich still doesn't mean that a HW2 calc is better than a HW1
one.
