two dumb RSX questions

Hello! Do what I do when I get confronted by a very unhappy system. Examine all of the steps you followed to get that far. And remember, the system you are looking at has a reason for being unhappy, and it probably isn't yourself. ----- Gregg C Levine gregg.drwho8 at gmail.com "This signature fought the Time Wars, time and again."

anyone have a physical 9 track tape drive still working?

If you have a brusys.tap file, would you please send me a copy? I can't seem to find that anywhere. Did you try booting the BRU64K tape? Sounds like that should be a BRUSYS system as well. Not sure what the correct name is. I know it by BRUSYS, but there might be some slight difference between the 11M and M+ standalone BRU, or it might just be different versions of the same. BRU64K also rings some bell, so I think I've seem that name as well. I booted it. It seems BRU64K does not support MU: devices. The "regular" BRUSYS does. I don't know what other differences there may be. BRU64K "might" be able to fit into a system with merely 64 k RAM... (And might be older than your other BRU immage ...) Ok. I was mainly concerned about the stuff fitting...I'm assuming 4.2/4.3 are larger than 4.1. 4.1 was the last version I ran. I've found the relevant sections of the documentation and am reading it now. Excellent. Progress! I've restored the DL installation set under simh, moved the RL02 disk images over to a (real) VAX, written them to RL02 packs, and am running a sysgen on a (real) PDP-11/24. It's midway through the assembly of the executive. I took a crappy phone pic: http://www.neurotica.com/misc/pdp1124-rsx-sysgen-20131223.jpg (yes, that bottom RL02 really is dirty...I'll clean it soon) I wish I still had that tape, but sadly it was lost many years ago. Distribution tape for 4.1? I thought you had 4.3 anyway, so what would you use 4.1 for? I wouldn't...but it was a pristine, original DEC RSX-11M distribution tape, and those don't exactly grow on trees. Thank you Johnny. I'm sure I will have other questions as I become reacquainted with RSX. No problems. Feel free to ask anything. Thank you! First question: I'd like to try to get DECnet running on this system, if possible, to get it on HECnet. I've never run DECnet under RSX before. I could put a DEUNA in the machine, but I am running short of slots. I have a DELUA, but I don't recall sysgen asking about DELUAs. Are they compatible at the driver level? Meaning, if I re-do my sysgen to include a DEUNA driver, will that work with a DELUA? -Dave As I remember the SYSGEN/NETGEN task, the controller intended for DECnet should NOT be taken into SYSGEN at all, but later, at the totally separate task of performing NETGEN once Your OS. is up and running, it should be included there. So, no need to redo your SYSGEN when playing with different Ethernet cards. BTW: DELUA replaced DEUNA... /G ran -SM6NNC

two dumb RSX questions

They have different microcode, but that is detected at runtime, and the right microcode is loaded. The rest work the same. They use the same drivers, both in DECnet and in plain RSX. (Yes, there is an ethernet driver for Unibus, that you can use if you have the controller, but do not want DECnet.) What're the differences between the two again? I have a DEUNA for my 11/44 I still need to get rolling. The DELUA is one board, while the DEUNA is two, I can tell you that much. Right. In addition, the DEUNA have a PDP-11 at the heard, while the DELUA have a 68K. An -11 powering the NIC for a bigger -11. neat. ;) So, at the microcode level, they are totally different. The DELUA also have a better ethernet controller (a LANCE chip). In short, the DELUA is improved in most ways. But it's fine details.

VT320 issues

by gregg.drwho8＠gmail.com

Hello! The last time I had a monitor throw a spanner into its flyback, and this was a long while ago, when I found out why they need them, it was a problem to find a new one. Then since the first repair firm fouled it up, the second stuffed a generic inside and it continued to work for many more years. (Actually they looked up what was the designated non manufacturer's replacement number for it.) Cory see if the blasted thing has a serial number on it, and ask Google. Worse thing that can happen is that the example will be unknown to it. ----- Gregg C Levine gregg.drwho8 at gmail.com "This signature fought the Time Wars, time and again."
