All: I want to use a sheet of Plexiglas to make a case for my KIM-1. Fabrication isn?t a problem, but I wanted to open it up for discussion about any static electricity issues. Should I be concerned about using Plexi for this project or what recommendations do y?all have for mitigating the possibility of damage. Thanks.

If you alternate forward/backwards it takes some skill to get as high as 8 tall :-). I guess I found a home for them, 'cause I didn't drag them all along in the next move! Tim.

Extracting CDOS files

by dave06a＠dunfield.com

Hi Guys, I've been approached by an artist who has many 5.25" Cromemco CDOS disks containing artwork from early in her career the she would like to recover. She has already made arrangements with the supplier of the original software to convert the files to something she can use on a modern PC, however she needs the files extracted from the CDOS disks. As there are several hundred disks, I would really like to find a PC based solution which I can automate. So far I can have tried the shareware version of 22disk, which can list the directory, however it reports multiple linked sectors in two of the three sample disks I am looking at, and also gets unrecoverable errors on sector 1 of every track (sector 1 on Cromemco disk is problematic with a PC - I've already got the drive slowed slightly, which allows ImageDisk to read and recreate the entire disk. So I have access to all of the sector data, but no way to feed it to 22disk. I've also tried Uniform, however it gets an unrecoverable error on any attempt to access the disk - in fact the error comes at the moment the drive selects, so I don't believe it's even trying, possibly because the P200 PC in my imaging station is "Way too fast" for software timing loops etc. So I am left with the option to extract the files from the ImageDisk images - what I need are technical details on the CDOS file system. CDOS is "CP/M compatible", does anyone know if the file system is identical - if not, can anyone point me at technical details. If yes, can anyone point me at a good description of the CP/M file system (It's been years since I needed to dig deeply into it). Anyone got source code ('C' preferred) for extracting files from CP/M? I have found sector->cluster mapping tables in the back of the CDOS manual, which hopefully will help sort out the XLT issues etc. Any other assistance/suggestions/pointers etc. would be most welcome.

Generally I have to agree. That said I'm the throwback here I guess. Of the 45 or so machines I have they are grouped by how I use them. Some like the 6800D1 and SC/MP very rarely see power. Others like my IMP48 and COSMACELF are small and don't need a terminal so its out and played with. the PDP-8, PDP11s and microVAX are all out and accessable. Same for the DECmateIII and several of the CP/M machines. Now there are machines I don't use but are occasionally brought out to insure run. I also have a small group maybe 5 systems that haven't run in 5 years as their status is "second copy" which is a working system but not intended for regular use. If there is one constant it is there are systems in that group that see power often and are part of my prefered tools to do various things. The fact that those tools are a bit retro is less important than they work and any bugs are well known. Allison

Indigo 2 - no video.

by trasz＠FreeBSD.org

I just got a "teal" SGI Indigo 2. Problem is, I get no graphics output. When I turn it on, the LEDs on keyboard flash once, the LED on the I2 turns on, after two seconds turns off, then turns on again and stays turned on. I hear the boot tune. Monitor is SGI 20E21, connected via 13W3 cable, but it gets no signal (or at least no sync) from the machine. Manual says something about "dissonant piano chord" - how is it supposed to sound like? One thing I've verified that without graphics card the chord sounds the same. NumLock LED on the keyboard does not light when i press that key. Is there some way to reset the NVRAM or something like this? Note that there are no SCSI disks installed - the bays are empty. -- If you cut off my head, what would I say? Me and my head, or me and my body?

It executes several small .com files and then put up a big splash screen on the VT220 for "DBL/RT11/TSX by mumble mumble Corporation" or something like that, but freezes halfway through it and won't do anything until reboot. Now I just need to download a TSX+ manual and figure out how to remove/modify the startup files. Is this disk something the list is interested in, or is it easy to find a working TSX image elsewhere?

The use of Plexiglas for mounting PCBs

The biggest problem, IMHO, of plexiglass is that static buildup attracts dust to the case :-). That said, there are anti-static sprays and "static-dissipative" and "anti-static" acrylic sheets available if you're worried about either ESD damage or just all the dust! I don't think it's sold by Rohm directly so you might want to use "acrylic" rather than "Plexiglas" in google searches. McMaster-Carr is a great place to get the stuff if you don't have a local plastic shop that stocks it. (I used to have a really really good platic shop in my neighborhood, but it got bought out by a national chain and now the retail side sucks rocks.) Tim.

DEC RSX-11

HALP! I just decided to attack a micro-11 system I had not attendded to. Good news is it's pristine and complete: BA23, 11/23BH, 512k (M8057), DEQNA, RQDX2(late firmware). The RD52 has RXS11 and boots. It's been a long time since I used RSX and longer since I've administered it. So some procedures for doing things I need to know or a pointer to. TO shut down I do? TO change admin password how, and which account again? If I add a 8line mux (DHV or DZV) what the procedure to get system to install and recognise it. On line DOCs to refresh memory from?

While looking for something else (ain't that always the way of it? :-) I came across this box... Apparently an Olicom OC2132, it's a microchannel ethernet adapter. This is in the original box, and there's some software and documentation in there as well. I looked at the card and there are AUI and RJ45 connectors and some LED indicators on the metal bracket. I have no microchannel hardware, having divested myself of the last of it a while back, and no plans to get into any in the forseeable future.

TSX on RL02 pack?

While playing with my 11/23+, on one of my spare RL02 packs, I found some interesting files.

Now I know nothing about TSX but do those filenames sound like it might be that operating system? I tried to boot from the pack but instead it came up in RT11SJ. What have I got here? thanks Charles

If it isn't, "RUN $SHUTUP" will do the same deal. As others mentioned, LB:[1,2]SHUTUP.CMD is invoked as a part of the shutup procedure, and shouldn't be invoked by hand. > TO change admin password how, and which account again? "RUN ACNT" if ACNT is installed. Otherwise "RUN $ACNT" will do it. The "SET PASSWORD" command is something that only exists in RSX-11M-PLUS, but if so, then it works just as fine from MCR as from DCL by default. ACNT is the general account management program. From a privileged terminal, you can change any account. In 11M, you can only change your own password with ACNT. In 11M-PLUS, ACNT is not usable by non-prived terminals. And there isn't any explicit admin account in RSX. The closest would be [1,54], if it exists. It does by default, which is why I mention it. But there are no problems with just deleting that account if you want to. Any account with a group number <= 10 is a privileged account. What this means is that when logged in, the terminal will have the PRIV bit set. Other users will have it cleared. Most things go on the terminal info bit when checking for privs. Run ACNT, and you can list all accounts, and see which exists with privs. > If I add a 8line mux (DHV or DZV) what the procedure to get > system to install and recognise it. Phew, big question. In short, you have two ways: 1) Do a full sysgen, which includes all the devices you want, and you'll have it. This will take a couple of hours, and literally hundreds of questions. A manual is almost neccesary. 2) Just build the device driver and load it. This requires that your system have been generated with loadable device drivers. You still need to figure out how to build the device driver. There are commands scripts that do these things, but they expect to be called as a part of SYSGEN, so doing it by hand will require some hands on fiddling. If you want a device driver to be abailable each time you boot, you need to add it to the system image you're booting. That is done by VMR. VMR is done as a part of SYSGEN as well, but if you build stuff yourself, you'll have to either add them in VMR as well, or load them at boot time in the startup script. > On line DOCs to refresh memory from? I think I saw that SRI now have some RSX manuals online, and of course, we also have bitsavers. There is a whole manual just on the SYSGEN process. Read it. :-) > I'm most comfortable with VMS, Ultrix and RT-11 but never > bothered with RSX for a home system. VMS knowledge can be of some help, but not much of anything else. RSX is so much fun.

MFM or ESDI QBUS controller for one PDP-11/23 PLUS

by hoelscher-kirchbrak＠freenet.de

Sergio, I made good experience with the SRQD11 Controller for ST506 (=MFM) disks made by the Australian Webster Computer Corporation. It can interface one disk (genuine DEC RDs or any other MFMs) to your PDP-11 or MicroVAX without any additional boards or panels. Mine has been running as well in my PDP-11/03 [RT-11] as in my MicroVAX I [VMS], which is VERY picky about disk controllers. Another good choice would be an Emulex QD21 for ESDI disks or even an Emulex UC07 for SCSI disks (if you find one). Ulli
