Hi! RogerHallett,
Yes, exactly, the TMX is named by the BAS project team of Mr. David Nanda in E&M Dayton. Originally, the project team of Mr. Jerry Butler in E&M Columbia had modified the VERSADOS realtime OS, which is provided by Motorola, with attaching several functions for the small controller based on MC68010 MPU which was different from the tower 1632 office systems. The BAS project manager tried to evaluate the availability of the Xenix that Mr. Bill Gates renamed the UNIX. However, E&M Dayton imported the OS architecture of VERSADOS from E&M Columbia into the BAS 5000 system, in order to install this modified VERSADOS through attaching several midleware functions for supporting the application friendliness to assist the transaction processing on the Branch Automation Systems. They called this application friendliness as the TMX (Transaction Management Executive). Originally the VERSADOS had been developed by the Motorola. When I attended the VERSADOS lecture room during a week by the Motorola instructor in the NCR Dayton Sugar camp in April, 1981. I was very surprised by the weight functionality of the VERSADOS comparing with the MTS 8 bits Intel MPU. I suspect that the Motorola strategy would be based on the simple procedure program like the 68xx MPU based application under the multi-tasking MC68010 MPU systems. However, on the other hand, the NCR system engineers might looked at this flexible OS like the versatile B4 executive on the powerful Century 300 processor, without detailed simulation of the performance of the TMX based MC68010 processing. Although I am not sure the availability of LAN (might be OMNI-Net of NCR, 2Mbps transfer rate during the time), the BAS controller supported the IHDLC high speed communication and also the analog type communication for NCR C-270 and ATM etc. I suspect that this IHDLC high speed lines would make high rate interruption for MC68010 MPU. I experienced to discuss much time to make sure the performance of total volume processing for the banking transaction in the Japanese financial market. The product management had been very significant in the BAS development, I studied. Best regards, Katsuhiko
