I need to use IBM PCs on a LAN (not specified which) as terminals to
our IBM mainframes, and want something approaching direct 3278 performance.
I can currently run telnet over Ethernet into a Spartacus box; good
performance, but the Spartacus is only here on loan, and has some
stability problems. When I get tn3270 for the PC (real soon now) I can
also try via Wiscnet and the DACU.

Alternatively, there is the gateway approach using coax connections to
a 3274 (I am not interested in gateways using a serial link to a 37x5).
I could get a dedicated box from Ungermann-Bass; would be OK, but a closed
solution. Alternatively, I know about PC-based gateways like the DCA
Irmalan or CXI PCOX, which work on any NETBIOS network.

First question: have I missed any possibilities (yes, I know that the
Token Ring will offer a more direct connection)?

Second question: is there much user experience of such products? How
does the performance compare to a direct 3278/9? Load on LAN? Other
factors. If anyone cares to share their experience I should be most obliged.
