If I put some load (cat /dev/urandom | gzip -9 >/dev/null) onto the sender
machine even the big VXT.SYS image gets loaded successfully every time
so far.

I am not completely sure, but the console works and the board does not
show any errors in the TEST 0. The machine went through several hands
until it reached me, but the story says that it was running as X
terminal in its first life. It could be thrown out because of a defect.

Could you perhaps dump the ROM and send it to me? I do have 14MB RAM,
so thats not the problem.

Yes I am interested, can I download that somewhere?
