I just tried to order one from Circuit City Online. They bounced my order - their web site will not let you backorder "out of stock" items. Bleah. --Pat.

PDP-11 Emulator Question

I want the parallel port for PLIP or for network or to possibly control an LCD module (if I can't control it from a serial port). > I happen to be lucky and have a few Xircom Pocket eithernet adaptors so > those will fill the parallel port. At the moment, I have no Xircom adapters (I'm casually looking for a bargain on a couple of PE-3s) and even if I had any, AFAIK, they only work under DOS and DOS derivatives, not any flavor of UNIX. There are pocket adapters that work, but I have never seen a working one for sale (there was this busted one at the hamfest...) As it turns out, one of the many pages on the iOpener that has sprung up claims that the modem interfaces to the motherboard with RS-232. I don't know if that means +/-12V or TTL, but it's a start. It appears to connect via a .1" spacing DIP header of 2x5 or perhaps 2x6 pins. Easy enough to squirt some data out the serial port and see what lights up with either an oscilloscope or even just a traffic light. > If linux supports USB there are all sorts of USB to whatever converters > including Eithernet, modems, printers... Depending on the USB chipset, yes. As I said earlier, USB support is imperfect under Linux at the moment. -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.

I'm not worried about stuff not fitting at all - I have been playing with entire functional distributions that act as dedicated web cams or routers and the like that fit on a single 1.44Mb floppy. For something requiring non-local space, it might be nice to mount over a network adapter, slow or not. I do have a spare 500Mb disk to throw to the effort. It's in that 486/DX4100 flatpanel box I've also got. As for fitting Linux on a small disk, I used to use a dedicated Linux router not based on a reduced kernel. It was on a 125Mb disk. No C compiler, no X, nothing but the kernel and basic networking. I had room left over. ISTR it was Slackware, vintage 2.0.30 kernel, whatever that works out to be. -ethan ObOnTopic - I'm interested in putting up Doug Jones' emulator and running an emulated PDP-8 on mine.I think it'd be cool to have the blinkenlights simulated under X and cut to an OS/8 window, all on something that is very portable. RadioShack sells a generic laptop adapter that some poster some- where claimed works with the iOpener, but it's $80! ===== 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.

TMS-7000 info needed

by kees.stravers＠iae.nl

I am looking for detailed information on the TMS-7000 microcontroller >from Texas Instruments. On the web information on this processor is very scarce. Among the many things I do is maintaining a web site for a Dutch Amateur Radio museum. This museum sometimes receives old rigs from the national PTT, so they can sell them to licenced radio amateurs. This way the PTT does not have to scrap them, and the homebrewers get quality rigs cheap, and the museum gets some well needed money. This time the rigs are somewhat modern, they are controlled by the TMS-7000. Rewriting the firmware of this rig should be enough to get it to work on amateur frequencies. The museum already has a pledge from someone willing to undertake this task, but he needs documentation on the processor. There is already documentation about the rig, but this only covers the radio part of the set, not the computer part. Does anyone have detailed info on the TMS-7000, like instruction set, appnotes, etc? This would be a great help. Thanks in advance.

Hayes Stack Chronograph Manual on-line

by bill_r＠inetnebr.com

I've gotten several requests for the Hayes Stack Chronograph Owner's Manual. I finally got around to scanning it and putting it up on my web site. It's available at: http://incolor.inetnebr.com/bill_r/archive_of_esoteric_documents.htm Hope this helps some of you who have been trying to figure out how to run the things! :-) -Bill Richman (bill_r(a)inetnebr.com) Web Page: http://incolor.inetnebr.com/bill_r Home of the COSMAC Elf Microcomputer Simulator, Fun with Molten Metal, Orphaned Robots, and Technological Oddities.

Need RS6K help

by peter.pachla＠wintermute.org.uk

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.

<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...)

by allisonp＠world.std.com

<>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

<"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

<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
