Now that the PDPjs MACRO-10 Mini-Assembler is [limping along](/blog/2017/03/21/), it's time to start assembling some
of DEC's PDP-10 "Basic Instruction" diagnostics and loading them into a test machine. The first diagnostic I tried was
[KA10 Basic Instruction Diagnostic #1 (MAINDEC-10-DAKAA-B-D)](/apps/pdp10/diags/klad/dakaa/), which has been loaded into
[KA10 Basic Instruction Diagnostic #1 (MAINDEC-10-DAKAA)](/apps/pdp10/diags/klad/dakaa/), which has been loaded into
the machine below.

@ -68,7 +68,7 @@ Based on the comment, it's clear what they really meant was either "[0,,-1]" or
desired result, which means that even when the assembler parses an mnemonic-less instruction like "0,-1", it must still truncate
the second (address) operand. Once I generated the appropriate value (000000,777777), the test passed.
