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.

Nope, that jumper has never been touched, and by the way, it doesn't just disable the extended CGA modes, it disables the on-board CGA adapter altogether... > ><This information is provided by an individual and is not nor should be > construed as being provided by Radio Shack or Tandy Corp.

Bollinger > @ <trsvax!earl> I certainly hope they wouldn't...I'd have to laugh if a salesperson gave me that info...anyway, I don't have anything against Earl, and I appreciate his input, just make sure of yourself nextime...BTW I requested that replies be emailed, not posted...oh well. Thanks for trying... I, and others have come to the conclusion that the bug is definately software, related, because when viewing a picture larger than 320x200 on Cshow mode Q(?) you can see the whole thing when you pan accross the picture...the problem is with pictures that are 320x200 - no panning...oh well. I am in the process of sending a letter to the authors requesting a fix.

He will be releasing a new version (8.1?) to rectify the problem. This bug was discovered on CI$ too, and that's where he hangs out in the Graphics Support Forum. Gary
