/* ---------- "Bug in Cshow8.0?" ---------- */
I've been starting up the latest version of cshow on my Tandy 1000 with the #j
option which is supposed to enable the PCjr/Tandy graphics modes, but when I
go to view a gif file in one of the two extra modes, everything is put on the
top line of the screen. Well, does someone have a fix, or is this a genuine bug
or what? Please e-mail me, and I will post any helpful information to
comp.graphics in about a week. Thanks in advance!

    For this answer, I assume you have a Tandy 1000 SL or TL machine.

    Your problem likely stems from having the "video/Interrupt Jumper" set
    incorrectly for your application. This jumper is located on the motherboard
    of the machine. If the jumper is set pins E2-E3 you are basically "IBM"
    conmpatible, if the jumper is on E3-E4 then you are IBM PC-JR or Tandy
    16 color mode compatible. This allows software to utilize Interrupt 5 for
    video graphics in the 16 color modes. Of course, certain hard drives or
    network boards could have conflicts with this jumper setting.
    
    You should be able to find information about the location of this jumper
    in your owner's manual in the Troubleshooting section, under Video problems.
     Plus you can see the jumper detailed in the board layout diagram too.
