Our site has a Sytek LAN acting as a front-end (terminal logins) and controlled by a UNIX-based Network Control Center (NCC). We have an Ungerman-Bass (UB) LAN serving the back-end (file transfers) and controlled by a CP/M-based NCC. We're inteested in moving the UB NCC to the same UNIX box serving the Sytek NCC. Are there any CP/M emulators out there that would allow this? Thanks, -- Jim Chappell ...!seismo!vrdxhq!ms3!jrc ISN Corp. 1235A Jeff Davis Hwy, Suite 605A Arlington, Va 22202

We have also evaluated the UB LAN's. From what I've heard, even if you can find a CP/M emulator for unix, it's going to be EXTREMELY slow. Anyway, the UB software running on the NCC isn't going to know where to find it's NIU. In other words, what you want to do won't work. My suggestion is to trade in your UB NCF on one of their NMC's. This unit is a IBM PC/XT (works in an AT also) with a PC-NIU installed. I think your running something like Ver. 10 software on your NCF. The current version on the NMC is 14. This version uses windows instead of all the boring menus on version 10, and is about 4 times faster. It also supports all UB's new 180, 130, and 74/78 products. If you already have an XT or AT around you can just buy the PC-NIU and software. Mike Ewan Broadband Network Operations Tektronix Inc.

There is a product called "The Bridge" (sorry, forgot the name of the supplier) that has a CP/M emulation system. There were two flavours: 8080/Z80 software emulation, and full hardware support (4 Z80's sitting on a "peripheral CPU" card). The latter was pretty fast. I think that they had higher speed bitslice Z80 emulator cards in the works. Then again, the hardware was unibus (for a VAX). I saw it running wordstar and a few other things under VAX 4.1 BSD. We were going to get them to port it to a Z8000 UNIX box until our project folded. -- Chris Lewis, UUCP: {allegra, linus, ihnp4}!utzoo!mnetor!clewis BELL: (416)-475-8980 ext. 321
