+videofx Posted November 16, 2018 Share Posted November 16, 2018 I just got a brand new Kaypro PC (built 1989). It has a 5.25 360K floppy drive and 20mb hard disk. I copy all the files to my hard drive. I then do TI99_PC /menu or I have also tried just from the command line and I try to format and create a disk and as soon as I hit F6, the floppy drive LED never comes on and the PC locks up and have to power down to reboot. Ctl-alt-del has no effect Anyone have any idea? Thanks Quote Link to comment Share on other sites More sharing options...

Also it may be a incompatibility with the DOS, what version do you have? Greg Quote Link to comment Share on other sites More sharing options...

+arcadeshopper Posted November 17, 2018 Share Posted November 17, 2018 Nice so did you read the doc file about controller compatibility Sent from my LG-H872 using Tapatalk Quote Link to comment Share on other sites More sharing options...
+videofx Posted November 17, 2018 Author Share Posted November 17, 2018 Nice so did you read the doc file about controller compatibility It's not the controller. It the PC. I thought and XT with 360K floppy would work. When reading the manual I found this: You will need an AT class PC. An XT class PC will not work, because the software uses some AT reserved instructions. I was going to try my IBM PC XT I will try just for fun. It should show the same behavior as my Kaypro XT 4 Quote Link to comment Share on other sites More sharing options...
