Hallo, It depends where the softzare runs: I have a software - can't remember the name - that can format an PC disk on a model 4. As the model 4 can't see - ...
Hei Supercross runs on the TRS-80 and can read write quite a lot of formats. I tried all that had any resemblance to 720k floppy. The disk would not be...
I use a version of Supercross that runs on the Mod. 4. [Supercross4 may be the wrong name; long ago, I renamed the program SX4.] There is no indication that it...

Thanks for your reply. Used to do that, too. But the 4P is miles from the other machines, not near a phone line, and the modem on it failed about 20 years...

I have generated a csv file that contains a list of every file on every disk in the zipped up archive. This makes it much easier to search for a specific file...

Well update 2 didn't last long :) Found the missing disks (#89 and #99) so have added them to the archive. I have also scanned in all 159 index cards (#71 is...

I have several very nice looking floppy drives where the only problem with them appears to be improper alignment. I'm under the impression that properly...
Yes, you need a special alignment disk. I've seen them on eBay but they sell for $$$$$$$$. You also need an oscilloscope - oddly these are cheaper! Neil...
... The most reliable way to re-align a disk drive IS to use the proper disk align disks and tools however if you don't have access to them and/or the $$$...

The 4p is a different beast, because it didn't have the rom image built in like the 4 and earlier models, so you have to have it on the disk so it knows what...

The 4P has no Model III ROM. When it identifies a DOS as not being TRS DOS 6.2 it looks for a file called MODELA/III and tries to load it. If it is not there...
