[comp.sys.ibm.pc] ROMS and BAR CODES

randy@ncrcae.Columbia.NCR.COM (Randy Smith) (02/06/89)

Greetings,

I have several questions about two general topics that probably have been
discussed many many times before.  Since my background is in the 68000 world
I don't really know that much about the IBM-PC's or the intel chips that they
have in them.  Please reply by E-mail so I don't clutter up this news group
with material that has already been covered.  Thanks in advance for any help.
Now, on with the questions!

I have an application that needs to be put into EPROM's and run on the PC.  How
difficult is it to accomplish this?  The application will be written in C.  It
will be straight reading the keyboard, doing some calculations and then writing
to the screen.  The PC will not have disks in it if I can get away with it.  Do
I need a card that emulates a disk with DOS on it or do I have to do all of the
DOS stuff myself?  What is the best compiler to accomplish this?  How does the
boot sequence handle a user supplied ROM if at all?  Will Julia ever see Mark 
again?  Well you get the picture.  I have absolutely zero knowledge about this 
and I need help in a bad way.

The second topic in the panel discussion today is bar code readers.  I have 
another application that requires the use of bar code readers and once again
my background in the 68000 world is getting in the way.  I have searched the
february issue of Computer Shopper only to find one ad that mentions that this
company knows a guy in Phoenix who can get one if I do three back flips in the
shower while singing a duet with barfy the wonder dog.  Am I missing something
here?  What types of readers (bar code) are out there?  What types of bar codes
do they read? (I understand there are several flavors to choose from)  How hard
is it to write software for these things?  Where can I buy some (readers)?  How do I work this?  How did I get here?...

Please, please, please, please...I need help.  Thanks again.
