Like the VS DSTK project this can re-assemble the original bin using the GNU tools on a linux environment. If browsing the contents of the archive on windows use wordpad which can handle linux text files fine. It seems these methods are working fine for newer bins

update: memory.x page0 should be start 0x0000 length=0x400 (which will provide a ram range 0x0000->0x03FF). Length in version 1 package length=0x3FF is off by one (provides 0->3FE)

I've been having a bit of a look through this disassembly, and I have noticed that it reads and writes to memory in the 0x1800 - 0x1Cxx range.
Is there another memory device on the bus (since writing to the memcal is pointless being an eprom) ?

I think thats the I/O addresses for control of the ports/pins.

this is in reference to one of the Holden calibration engineers that passed away during the development phase of VT S/C
