Hi, I've just gotten hold of an RS/6000 which appears to be a model 520 (7013?). Since the thing appears to be a server (POWERserver?), and thus has no display adapter, I need to get hold of at least one of the 10-pin to 25-pin serial port converter cables. Can anyone, preferably in the UK, help please? Also, does anyone know where I can track down a set of AIX 3.1.0 manuals - printed or electronic form? TTFN - Pete. -- Hardware & Software Engineer.

PDP-11 Emulator Question

by allisonp＠world.std.com

<One of the links I posted earlier mentions that there are two related Linu <distro's in the works. One will fit on a 500MB HD, the other will fit on <the SanDisk. Gee, I hate to tell you this but, I just installed RH5.2 on a 500mb drive no problem. So I put Openlinux2.3 on it to see the difference. It's very doable. I've got an old copy of FreeBSD 2.2.6 that would runs just fine on a st3660(500mb). Also I've been running NT4.0/sp4 worktstation on 486dx2/66 in 500mb (310mb free). NT for that box may be problematic due to drivers for video and all. Another OS that is a good candidate is MINIX2.02 as the whole can fits on 40mb with sources. I've run it on 10mb disk and 4mb ram. There is MinixVM also. I think there are plenty of possible OSs for that toy. Most all of them run some emulator we'd like to use. Allison

Compact QBus Systems (Was re: Los Angeles: Commodore PET 8032's...)

<>The BA11M however will take a lot more cards though but is very noisy. < <I was going my memory of the ones I have had. The last one was 6 to 9 <months ago. I will have to keep my eyes open for more. They a handy size I have one, tucked away. Nice for somethings being front loading. The fans are way noisy though and running them without is bad juju. I have run it with both in series so they run at 1/3 speed and it's quieter but you have to watch the heat, modest systems run fairly cool. Allison

PDP-11 Emulator Question

<"slashdotted" they'll change their policies. For that matter, <until you have the unit in your hot little hands, they could <still change their policy and simply refund your deposit. There is implied contract at the time of sale. Also those that act fast will win as it takes time to change those things. This can facilitate a lot of projects, I plan to see if MYZ80 and DOS can be popped into the Flash as that package is only a few kilobyts and the disks are the space grabbers. Allison

PDP-11 Emulator Question

by allisonp＠world.std.com

<Looking into this some, and I expect to see the purchase policy and if the <can afford to the hardware design change. There are people ordering 10 or <more of these suckers to convert them! They have you locked as the numbers that will convert are relatively small and once you power it it connects to them and asks for a credit card. You locked with their software. My concern was initally is was it a PC or something not so PC that only runs very custom stuff and you need to know whats down deep to port something like linux to it. For $99 I took the plunge. It's on order. Allison

PDP-11 Emulator Question

by allisonp＠world.std.com

Well first off I've ordered one as it's interesting. <The problem with this box is that there is no way to import software since <the SanDisk is soldered on, not plugged in, like some embedded designs. Wh <appears to be necessary is to install an alternate OS on a laptop drive tha <is installed in a _real_ machine, then stick the drive on this closed box. The disk installed has only got to boot dos or some such. Then the parallel port can be the import path. I've already done this on regular PCs that I didn't want a Floppy and CDrom on but needed to install W95 or whatever. Once you have an OS you and install a Sandisk loader in the Sandisk. Dunfield.com has a minimal dos that may work for the task. <There does not appear to be an RS-232 port, but I have two options - one <quick-n-dirty, the other only theoretically possible. First, I have a <box that simulates a CO. I can stick a modem on the other side of this <thing and use its internal modem at 33.6 (maximum speed without a digitally <enhanced ISP on the other end) or down to 9600, say, and simulate a dial-u This is one way, Ugly and prone to problems. Easier to hack the parallel port and do a parallel to serial converter. I consider the parallel port a resource. I happen to be lucky and have a few Xircom Pocket eithernet adaptors so those will fill the parallel port. <> Do USB drivers for DOS exist? < <I sincerely doubt it. None I know of. <Agreed, but I may stick a Linux Router Project kernel on the internal SanDi <and mount stuff via NFS - slow over the parallel port, but it should work <once I get an adapter. If linux supports USB there are all sorts of USB to whatever converters including Eithernet, modems, printers... Allison

HP 2000 TSB question

by west＠tseinc.com

I finally finished testing out all the memory boards in my two HP2100's. I was getting misleading results for a long time due to my lack of understanding of the way the memory subsystem operates - it has to be tested in a very specific non-intuitive (and undocumented) way. Turns out I have four bad boards; three 8K SSA core stacks and one 16K ID board. These two systems ran HP2000 Access TSB, and had 32K each. My question is (before I spend time hunting down replacement boards) does anyone know what the memory requirements for the main and IOP cpu's in 2000Access is? If I can get by with less than 32K in each cpu I can forgo getting replacement boards for the time being and perhaps run with 24/16. Any ideas? Jay West

Can someone here telnet to my 11/35

by dylanb＠sympatico.ca

Thanks everyone for telnetting into the 11/35. It seems the 11/35 could handle the guests but not my PII-350 :-(. The terminal server is now repaired and it looks to be stable. .. though probably not as stable as the 11/35. I will be putting online many different PDP-11s/PDP-8s online throughout this week and the coming months. The 11/35 will have FORTRAN IV, MACRO and FOCAL added to it (with a lot more games) later on today. http://www.pdp8.com/telnet.htm Enjoy! PDP-8 and other rare mini computers http://www.pdp8.com

PDP-11 Emulator Question

The BIOS on this particular box seems to see it as the slave device on the IDE interface if there is a real IDE drive installed on the 44-pin connector. The problem with this box is that there is no way to import software since the SanDisk is soldered on, not plugged in, like some embedded designs. What appears to be necessary is to install an alternate OS on a laptop drive that is installed in a _real_ machine, then stick the drive on this closed box. > However, I'm wondering if there is a way to also use it as a Serial > terminal. There does not appear to be an RS-232 port, but I have two options - one quick-n-dirty, the other only theoretically possible. First, I have a box that simulates a CO. I can stick a modem on the other side of this thing and use its internal modem at 33.6 (maximum speed without a digitally- enhanced ISP on the other end) or down to 9600, say, and simulate a dial-up connection with whatever software is handy - I'm fond of Kermit myself. Alternately, it may be possible to remove the modem and add a MAX-232-based level converter and run a cable outside the case for "real" serial devices. I plan to inspect the innards and hang a scope off of whatever interconnects there are. Worst case, the UART is embedded in the modem and I'll have to be more creative by probably installing a 16550 on a daughter card in place of the modem. I don't know if I'll go to that extreme. > Do USB drivers for DOS exist?

Agreed, but I may stick a Linux Router Project kernel on the internal SanDisk and mount stuff via NFS - slow over the parallel port, but it should work once I get an adapter. -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away.
