I just "inherited" a 1985 vintage modem.  Actually, in its day it was
obviously one of the best...supports Hayes 2400 and MNP 1.  What I need
to know is if (sigh....never happy!) I can upgrade this beast.  It is
made by a company called ARK Electronic Products.
DDDDDDDDDDDDDDDDCCCCCDI have lifted the cover and
see that it has a Z80 CPU and a chip labelled "65AB V.062485 U4 24K
003096 RDV 2.21".  Also, there is a Z80 SIO/O chip.  I think the chip
with the long label may be the MNP chip?  Anyway, if I replaced the Z80
CPU with a Z80 A, and the Z80 SIO/O with an upgrade (is there one?) can
I get more speed out of this modem?  If the chip I mentioned above has
the MNP algorythms, can it be replaced with a more up to date chip?  Any 
help would be appreciated!!  Ohhh yea...has anyone ever heard of ARK?
