No need to create any files before starting MSPLAN. Backup batteries have caused many problems, but I haven’t heard of that particular one.
MSPLAN locking up can also happen if you are trying to run a program incorrectly hidden in HIMEM. For example, this program has a bug which causes MSPLAN to lock up with a blank screen: https://m100.bitchin100.narkive.com/56ABPoQg/y2k-fix-for-tandy-200#post29 10 CLEAR 22,HIMEM 40 FOR A = 61082 TO 61103 50 READ B 60 POKE A,B 70 NEXT A 100 POKE 61124,238 110 POKE 61123,154 120 POKE 61122,195 210 DATA 229 220 DATA 245 222 DATA 62,44 225 DATA 33,182,247 227 DATA 190 228 DATA 195,173,238 230 DATA 33,183,247 240 DATA 54,50 250 DATA 35 260 DATA 54,48 270 DATA 241 280 DATA 225 290 DATA 201 999 END 1000 POKE 61122,201 What happens when you try PRINT FRE(0) and PRINT HIMEM? (On VirtualT Tandy 200, I’m seeing 19334 and 61104.) —b9 On Mon, Aug 5, 2024 at 5:47 PM Tom Blum <[email protected]> wrote: > I've not opened the case yet, but am now thinking that the configuration > may be stock since: standard menu looks normal for T200, RAM availablre at > startup is per stock specification, no optional ROM is installed.
