TC1995 9c8c1a6f40 Trantor SCSI changes of the day (April 2nd, 2025) 
1. The PAS SCSI controller driver mamv1.sys dislikes having bits 0-6 set when a transfer has completed, take account from this, fixes mamv1.sys incomplete CD transfers (bits 0-6 get re-enabled when the transfer is ongoing).
2. I now understand why the T128 doesn't have a block count register, it does the block count manually from the SCSI layer directly, this fixes Pseudo-DMA transfers when using, e.g.: CD transfers using a sector size of 2340 bytes.
