If anybody still has a COS-3xx DIBOL system, I have two keys for the back doors :-) DF8 and DF32 cheers, Nigel Johnson On 13/10/2019 16:29, Jason T via cctalk wrote: -- Nigel Johnson MSc., MIEEE VE3ID/G4AJQ/VA3MCU Amateur Radio, the origin of the open-source concept!

In 1981-1987 i worked for a company that used the MCBA system subroutines to develop a system to do trust plan administration for labor unions. Mostly it was remote data entry by the unions themselves over leased lines using black box modems. The MCBA routines were pretty clever and solid. The screen routines used vt100 escape sequences to make "fill in" fields which then could be made to resemble a form. It ran on pdp 11/70. In 1982 we converted it to run on a VAX 780. Hardest part was converting from (i think) DMS 11 ( i think that was what the file system was called) to RMS. Sent from my iPhone

Later MCBA re-wrote the applications in DG Nova BASIC (IIRC). At Durango, we picked those up, wrote our own multi-user BASIC for the 8085 and 'ported the MCBA apps (AP, AL, GL, Payroll and Inventory) to our own system. Later, we ported our BASIC to Xenix and ran the same application on an 80286/80186 multi-terminal box. I still have the source code for those. --Chuck Sent from my digital computer
