SDX 4.49 - U1MB - SIDE2 - RespeQT - "symbol not defined" weirdness

hi all

Not really sure where to start, but the system seems to have been working. Lately, from SDX when I invoke a command like "DIR D1", the console presents messages like "Symbol SETBOOT

154 Symbol not defined"

 

At times, some commands produce a boatload of similar messages about symbols not being defined.

Maybe it's because I've been spending more time in Atari lately, but I don't recall having seen these 

messages before.

 

Ideas?

 

thanks,

Steve

the final test - no respeqt, no side2, and I still see these. Booting sdx from U1MB. that localizes the problem, at least.

Starting to think configuration. I admit the possibility that sdx on the U1MB could have (somehow) a corrupted image.

My side2 boots as D9:.  My config.sys:

USE BANKED

DEVICE SPARTA 6

DEVICE SIO

DEVICE ATARIDOS

; DEVICE INDUS 4

DEVICE ULTIME

DEVICE JIFFY

DEVICE RAMDISK

I recently swapped the keyboard to another machine for testing. apparently my wiring is sloppy. I've taken the cover off,

ensured that the wires going from the U1MB to the CPU are not interfering, and now running without cover.

Seems to be better. Guess I'd better clean up my wiring. Sigh.

Run an extended RAM test: http://atari.sk/extended-ram-test-0-22-0-xram0220-xex/

 

make sure the stock OS ROM self-test doesn't show red bars for ROM

 

Run a RAM test of the base 64K, don't have a link for software based ones handy at the moment, but there is this OS ROM replacement tester: https://www.jammarcade.net/shoestrings-atari-8bit-ram-tester/
