Tandy modification complete

Post by Vorticon »

Well I finally got the chance to perform the Tandy modification and so far tested it on FS3 and Silent Service II both of which work great with the Tandy option. Ultima V however does not automatically recognize Tandy mode and will lock up if forced to use that mode. Same issue with Gunship and Shinobi. Anyone here has a guess as to what could be the cause of that variability?

Walid,

I got the chip (74F86) required for the mod, which I'm planning on doing. Are you satisfied with it so far?

Cheers,

I works well with selected programs, but not with all. Overall a worthy upgrade.

Can somebody send me the instructions for this or link me to them?

I'm interested to read about the modification, but I can't find the details of the procedure anywhere.

Look for "jrto1000.zip" in http://john.ccac.rwth-aachen.de:8000/ft ... _specific/.

There's also "jrto10.txt" in the "U-612 PCjr Tool Box" folder of the archive http://www.brutman.com/PCjr_Club_Library.zip.

Right. Looks like Mike has moved or removed the file. Send him a PM or an email. There's some interesting stuff in there.
