Hello all! I am trying to define an environment which will allow our IBM
3090 machine to talk to a number of other hosts. Among these other hosts
are S/38, AS400, HP 925, DEC VAX 8600, etc.
The thought is to use a PC as a go-between. This will allow us to develop
a connection from the IBM 3090 to the PC (possibly using an LU 6.2
connection) that is standard for all hosts that want to talk to us. Then
all that is needed is to develop software that runs on that same PC to
connect to the other host. This obviously would be host dependant. We
would like to have the other host's application programmers code this
connection (see diagram's TRAN 3 and TRAN 4).
So, the question is what is the environment/hardware/software that should
be used on this PC.
It has been suggested by IBM to use OS/2 and CICS for OS/2. Is this the best
solution? What other possible architectures are available ????

We have a 3090-300E that is being gatewayed via an IBM 8232 industrial PC. The industrial PC is really an AT bus machine modified such that it speaks SNA on the channel side, and Ethernet via an Ungerman-Bass card on the other side. Hanging off of the Ethernet are various VAX, HP and Sun machines. Serveral applications are currently being developed using LU6.2 to one of the DEC machines running DECnet. In installation of FAL-FTP from IBM is currently also underway, to allow greater access for our 3270 users to general network services. Ask your SE about the IBM 8232. -- Mark A.

Or maybe I should say, if you're unlucky, since the 8232 is certainly one of the slower devices available for doing this. (Even IBM has admitted that the performance of the 8232 reeks, and is bringing out the 3172 as a replacement with better performance.) To add insult to injury, the 8232 is about 4 times as expensive as the BTI ELC which is easily the best and fastest device on the market today. I urge you to contact Bus-Tech Inc. 131 Middlesex Turnpike Burlington, MA 01803 (617) 272-8200 for information.
