Re: Ultrix 3.0 VAX
Dennis, It sounds like you are looking for an Ultrix 3.0 standalone boot tape. While I found a number of people who claim to have a physical tape, with some claiming to have imaged the tape, I was unable to find an image on-line. That being said, it’s possible to use the Ultrix 2.0 standalone bootable tape (AQ-JU00C, available from bitsavers.org) with a couple of edits at the end - I did this to get 2.2 up and running. Since Ultrix 2.0 only supports a limited number VAX processors, the first stage has to be run on one of those processors, I always use microvax2. Subsequent stages may be run on any processor supported by Ultrix 3.0. Stage 1: I use the following .ini file: # Boot from standalone tape. This MUST be performed on a microvax2 instance. set rl dis set ts dis set rq0 ra81 att rq0 system.dsk att tq0 AQ-JU00C-BE_ULTRIX-32_2.0_SA_87.tap set tti 7b set tto 7b boo Attach the Ultrix 3.0 supported tape to tq0 when it asks. This stage will create the root partition and restore from the tape. No special handling at this point, just answer the questions as for a normal install. Stage 2: Use the VAX simulator for the target system (I used vax780) and boot rq0. After answering some questions it will fail trying to create a file system on /dev/rra0 which doesn’t exist - you need to edit /.minidevice as follows: # ed .minidevice 22 1 RA81 ra 0 TK50 tms 0 s/0/0g RA81 ra 0g TK50 tms 0 w 23 q Reboot the system and it will create a file system on /dev/ra0g, copy the base packages along with any you have selected and build a custom kernel. After all this reboot again and it will drop you into single user mode after complaining about "Can't stat /dev/ra0ga”. Edit /etc/fstab: # ed /etc/fstab 54 1 /dev/ra0ga:/:rw:1:1:ufs:: s/0g/0 /dev/ra0a:/:rw:1:1:ufs:: w 53 q Reboot again and you should have a functioning system. John.

There seemed to be two compatible types of the keyboard - an older thicker keyboard (shipped the TS-803 et al, and looks like an enhanced 925/950 keyboard), and a newer thinner profile keyboard used on later terminals. >From what I've figured out, the 955 uses a 6-pin connector at 9600 baud with both Tx and Rx used, and a reset line and +12V power. The 925/950 use a 4-pin connector, replaces the Tx to keyboard line with a speaker connection, drops the reset line, and runs at 1200 baud as compared to the 955 keyboard. The keyboard should be the same between the 905, 955, 970, TS-803, and some others with the possible difference of some legends on keycaps. The TS-802, 800A, 925, and 950 use the same keyboard +/- some legends. Later terminals like the 965 use a 4-pin connector with a different pinout, and +5V supply instead of +12V, but still at 9600 baud with the same codes as the 970/etc. I believe that the transmitted codes are the same for all of them, but the older 925/950 keyboard is missing some keys than the later 970/955/etc have. The TPC-I, TPC-II, TS-1605 all use a PC/XT-like keyboard interface, but with a +12V power supply instead of +5V. I haven't quite verified if one can swap them with XT keyboards with an alternate power supply yet, but it may be possible. It seems like they should be compatible since the TS-1605/TPC-II are fairly compatible with PC/XTs. Pat
TSX-Plus help needed!
OK, I have figured out how to modify TSGEN.MAC, use PUTR to make a disk image, load it in SIMH, reassemble, relink, and *finally* send it to an RL02 pack via vtserver! TIme-consuming but doable. I've been wrestling with this all day. BUT - TSX+ 6.50 just will not run. At all. Using RT-11SJ (5.01), after typing "R TSX" I can hear the disc access for a few seconds, a pause, a few more accesses... then nothing. It just hangs. Nothing on the console either., no response to . When starting it in SIMH (the same disk image), I get the error message ?TSX-F-Computer line clock is not working. Figured that was just a SIMH thing. But the address/vector is correct in TSGEN.MAC... and when checking TIME in RT-11, the seconds advance in real-time like it should. On the real hardware, the error message doesn't display, and the clock is running... My old version of TSX+ is 6.16 and it runs fine on console and SLU 2, just needs rebuilt to use different serial cards than the original system. So where should I start looking first? RT-11 version incompatibility? Any TSX+ experts online? Thanks for any help. This is driving me nuts!
Re: Televideo 925 character rom dump
The keyboard controller is an 8049. Firmware not readable. It may actually be compatible with the 955 keyboard, which I was able to read. Key layout is the same, though the manuf is different

Re: VTserver problem (bug?)
And even more bizarrely... it crawled its way up to the 7400K block, and now it's going at normal speed again! 10MB should be done soon. I have no idea what could be causing this major slowdown from 6.6-7.4 MB. It's not the drive because two different ones do the same thing (and they work perfectly otherwise)... Hopefully I won't have to go through the (edit, reassemble, relink, PUTR transfer to an image, vtserver to the disk) loop too many times, attempting to get my DHV11/16D to function with TSX+ 6.50... I had somehow inserted a couple of characters that didn't belong there while editing (bumped the keyboard maybe?) so I'm on the second pass. Also I found what looks like a typo in the TSGEN.MAC file if anyone's interested.

I worked for NEC back then and had access to intel parts too. If you can't read it its your programmers fault, FYI the set up is nearly the same as 8749 but the voltage for the read function is lower. Here is except of page 2-19 of the intel MCS48 family manual july 78... "The processor is placed in the READ mode by applying a high voltage (+25V for the 8748, +12V for the 8048/8049) to the EA pin and +5V to the TO (8748 only) input pin. RESET must be at OV when voltage is applied to EA. The address of the location to be read is then applied to the same lines (TTL levels) of BUS and Port 2 which output the address during single step (see below), The address is latched by a "0" to "1" transition on RESET and a high level on RESET causes the contents of the program memory location addressed to appear on the eight lines of BUS." It is possible that the devices is being used with external rom/eprom the test for that is pin7 EA, if EA is high then program access is external. it was very common to use any 8048/49 in place of 8035/39 in a system and often cheaper due to misprogrammed parts that can still be used with external rom. FYI there are no "protection bits". Allison
Re: VTserver problem (bug?)
-Original Message- But there is some kind of bug that always appears at the same point, in the middle of the next 100K block after "6600K written". The data transfer stops (no more head motion/ready light flicker on the RL02), and the character that vtserver uses to indicate a write operation just repeats endlessly and rapidly until I kill it. More information and a correction: I let it run on, and it is still reading and writing, but at a much slower and intermittent rate than the first 6.6 MB. The filler character is just a time marker of some kind, since I can still see the "r" indicating a read from the .dsk image, and the light on the RL02 flickers after a few of those. So it's slowed way down, but not stopped! Even more mysterious. Anyway, this disk has 13800 blocks out of 20800 used. If RT-11 stores data (including the directory structure) starting from block 0, I may be able to kill the writes after 7 MB. (Unfortunately I think I neglected to squeeze the image before sending it to the RL - and naturally the important TSX files are near the end - which means I have to wait for most of it). If I have to do it again, I'll squeeze and then kill it after 7 MB and see what I got!

VTserver problem (bug?)
I sometimes use vtserver to download disk images to the RL02's on my PDP-11/23+. Takes quite a while at 9600 baud, too :) But there is some kind of bug that always appears at the same point, in the middle of the next 100K block after "6600K written". The data transfer stops (no more head motion/ready light flicker on the RL02), and the character that vtserver uses to indicate a write operation just repeats endlessly and rapidly until I kill it. Does anyone else encounter this limitation, and if so, how did you fix it? Fortunately I haven't wanted to image a disk that's more than 2/3 full so far... I make sure to squeeze the disk in SIMH before transferring the image. But it'd be nice to be able to image a full (10 MB) RL02 and not have to worry about it failing. Any ideas? thanks Charles
