I was wondering if anyone could point me to some good sources
of information on building computers. I am going to try to build
a partial computer that will consist of a turbo 8088, power supply,
floppy controller, one 3.5" floppy drive, and an RS-422 interface.
I've never worked with building computers before, so if anyone
can give me some pointers, or some sources of parts or info I'd
appreciate it. The sysytem is going to be an external slave drive
unit for a Laird 1450 Character Generator. I'm getting the driver
software to run on it, and then I need to build the hardware.
I was also curious if nayone would have some suggestions
as to weather I'd be better off using a standard computer case
and making it rackmountable or if I'd be better off putting all of
the components in a rackmount case. I was wondering if with a rackmount
case I might run into interference problems with the other video sources
in the rack. (S-VHS deck, switcher)
I was also curious if anyone knows of a product that converts
an RS-232 port into an RS-422, or if anyone knows of a good source
of RS-422 cards, and how much they cost. I've also been told by
one source that you can trick a device into thinking that it
sees an RS-422 by simply altering the pinouts on an RS-232 with
some resistors and diodes. Is this possible?
PLEASE mail anyreplies since I cannot retrieve Usenet
posts and it would be handy to have a hardcopy of any replies.
Thanks in advance!!!
