A VRAM tester for SC-3000/SG-1000.

If there are errors, the program will signals you with the number of beeps. If more than one chip has an error, the program stops at the first bad chip.

The table indicates which chips have an error in relation to the used machine.

Dropbox links will expire, our attachments should be around for a few more decades for anyone to look at. Preservation is important to us.

Ok. At first I tried to insert both image and zip file.
Is there a way to add multiple files? I haven't seen how to do it.
