Found these inside a non-working 71B

Quote:But that number (82437) still seems odd. A 1BBBB machine usually has about 17.5 KB free after a reset. Adding 64K => 83456, 1019 bytes more than it's reporting.

Did the machine have any files installed (e.g. a test program?) when you got that result using MEM ? Also, "DESTROY ALL" will remove any variable storage.

After Destroy All", i get a slightly diff number, 82415. Any chance it has something to do with Math ROM. Repeated Init3 and MEM is consistently reporting 82427. Bu oddly, everytime I do Desroy All. it changes to 82415. Repeatable. I see similar behavior on another 1BBBB machine.

INIT3, MEM =16955
DESTROY ALL=16943 12 bytes different, same dif as above. I don't see 17.5 on either.
And 65535+16955 is roughly what I see above. Should be identical but maybe Math overhead affects numbers. Plus, I don't think i've ever seen 17.5k with mem
