Hi Does anyone have an early model Vector Graphic computer with the MZOS ROM in it? It would be an early Vector Graphic computer (pre-1980) with 48K RAM. The MZOS ROM would be located at $C400-$C7FF. Even a hex dump from DDT would be useful or any other format I can convert. I need the MZOS ROM to be able to compute the sector checksum on some MZOS boot disks. Those disks are not readable with my VG machine or CWVG since they use a unique checksum algorithm. Actually, I can read the disks with CWVG but I cannot verify the contents of the sector with the checksum so I have no idea if the data is actually good or not. Thanks! Andrew Lynch
