Good news for those who plan to swap a VAX for a SUN: The Penn-State
Unix RSCS Emulation Program runs on SUN without additional hardware.
Using a pseudo device driver (Public Domain) one of the zs ports on CPU
board is made to talk BSC to an IBM running RSCS-V1. The user-level code
originally from PSU compiles and runs smoothly on SUN - no machine depenent
bugs, (just ordinary UREP bugs ;-)). So, if you want to have a SUN connected
to BITNET - there you go! Get the original UREP package from PSU ( send
e-mail to Dae@PSUVAX1.BITNET) which is $800 for an educational site, and drop
me a line and I'll send you the device driver.

P.S.
TAURUS.BITNET was a VAX/780 and is now a SUN-3/180 !loverso@encore.UUCP (John LoVerso) (01/21/88)

Thats unbelievable! I cannot imagine what change in UREP made it so valuable that the "distribution" fee was increased by 4 times! For comparision, for $1000 you can get all of 4.3BSD, distributed fresh from Berkeley and you get much more value for your money! Anyway, I ran a UREP-connected bitnet site (sunybcs.bitnet) for a few years, and had no end to the pains that UREP caused (between all the bugs and security holes). I would not put UREP up on any machine where I didn't want global access to "root". By "global", I *do* mean bitnet-wide access. If you're going to spend on a leased-line 9600 baud link (in the USA), you'd probably be better off running IP over it (SLIP, anyone?) and connecting into NSFNET.

Many new features and improvments have been added (chime sockets). actually urep2 is still available for $250. urep3 (the $850 version) was written to support the jes/nje line protocol. urep3 is also supported for the ibm rt/pc. the sna/udp/ip (yes that is sna over udp/ip) line driver is a real performer. it is interesting how people react to the cost of urep3. jnet (which started it's life as a conceptual port of urep to vms) costs big bucks. you do get n days hot line support but still. owens

Concerning my previous message on this subject: 1. I was wrong claiming the code is Public Domain. The zs_bisync.c pseudo device driver is based on the old UREP dup.c device driver written by Robert M. Owens, thus the code is Copyright by the Penn-State University. Please accept my apologies. 2. There has been a bug in the driver which caused occasional system crashes. This bug has been fixed, if you need the patch, please drop me a line. Leonid
