Frank - Indeed, the KYO 85 and the Tandy Model 100 are very close. But you are incorrect in one of your assumptions: It's memory addresses are NOT the same as the Model 100. They are close, but not the same. The reason you are experiencing the lockup most likely has to do with the machine language that is being executed with the CALL statement. Various things could be going wrong, it could be looking at high memory addresses which are different in the Tandy Model 100 and the KYO-85, or it could be making a call to a ROM routine which also are slightly different in both machines. It certainly is possible that the file manager loader could be modified to work with the KYO-85 so that FLOPPY.CO could be loaded into memory, but then you'd have an even worse problem: FLOPPY.CO, being a machine language program, is using even *more* RAM & ROM addresses that are proprietary to the Model 100. Bottom line: The software which ships with the Tandy PDD & PDD2 is incompatible with the KYO-85. Does that mean all hope is lost? Certainly not! There is another program which was first written for the Model 100 called Disk Manager. It can talk to both the Tandy PDD1 and PDD2, although on the PDD2 it can't read or write to the second file bank, so it can only store up to 40 files no matter which one you are using. But, if I'm not mistaken, you can still store up to 200K of information on the disk (not just 100K). Functionally, it is apparantly superior to FLOPPY.CO. Anyways, someone created a special version of DSKMGR.CO specifically for the KYO-85. It is available from CompuServe in the M100SIG forum. With it, you'll be able to use your Tandy PDD2. You don't happen to have a CompuServe account, do you? Gary Weber
