OK... today I discovered the real-time-clock on my 11/23+ was dead, so TSX-Plus wouldn't run properly. I tracked it down to a bad LM339 comparator (inside the chassis power supply, of all places). Miraculously, my local Radio Shack actually had one in stock and it is now working again :) The RL02 pack has RT-11 V4.00 and *two* versions of TSX-Plus on it. The files with the expected .SAV suffix are version 5.0, but there were also several .NEW files (including TSXMOD.NEW even though there was no TSXMOD.SAV). When I run the new TSX-Plus it's version 6.16. Unfortunately both versions are expecting a DL serial line card, not a DH, and they are not interchangeable as far as drivers. And (of course) LINDEF and DHVDEF are two of the short list of parameters that cannot be patched via TSXMOD, but require regenerating the system :( I was hoping to find the distribution files on the pack (such as TSGEN.MAC) but no such luck. So it sounds like I need a new copy of the TSX-Plus distro files... like the hobby-licensed 6.5 :) Jerome H. Fine, would you please contact me offlist if you can help? I've also emailed Lyle Bickley but I haven't seen him on the list in quite a while. thanks for any and all assistance. -Charles
