Subject: Re: Anyone have an RK8E to sell?
I did happen to go look at my RKV11D
and verified that there is an M993 card at the end of it, the same as
what the RK8E needs. I've read recently about folks thinking of hand-
crufting cables and if that's the case, I'd be glad to photograph/scan
my paddle card if that would help anybody.
Of note is that on the M99E card, there are traces, etc., for a single
DIP part and some associated discrete parts (resistors?) but they are
unpopulated. Would this have anything to do with the differences between
some of the drive implementations, especially as regards to unit select
lines?
I thought that the RK8E needed the IC and the original cable I am using with
my RK8E does have it installed. I have a schematic in the RK8E printset
but it doesn't show the IC. I have a cable around without the IC but have
not tried using it. If find you need the parts on the board I can pull
the cable and find out what they are.
The RK8E (with M993C) and RK05 schematics are on my web site
