I may be calling referring to it by a term that falls outside of common Model T / TPDD knowledge. I guess I'd thought it was more well known, sorry about that.
TS-DOS 4.0 and earlier has a limitation whereby it only will display two pages of files (40 total I believe). If you press SHIFT-DOWN to try to get to a third page of files to display, you would just get a full screen of " -.-" instead of the third page of files. Years ago, Ken Pettit created a fix and released TS-DOS 4.10 where this limitation was eliminated. Kurt McCullum also incorporated this fix into SARDOS. Well, there's a TPDD client built into the BoosterPak BP1 system ROM, and it still exhibits the limitation. I was getting annoyed by not having access to the third page and beyond of files to display. Therefore I incorporated the same type of patch into the embedded "TS-DOS" client that's buried inside the BP1 ROM. If you use my image instead, now your BoosterPak "Disk" view will let you page through an unlimited number of new pages of files to display. Gary On Tue, Jul 14, 2020 at 1:59 PM John R.
