IC history and chip art

by philpem＠dsl.pipex.com

Hi, I just found a scanned/OCR'd copy of "State of the Art" by Stan Augarten on the Smithsonian's website. It covers integrated circuits from their creation right up to the 1980s - the URL is: <http://smithsonianchips.si.edu/augarten/index.htm> Some of the pictures are quite neat, as are a few of the little facts - the origin of ZiLOG's name for one (that's on the Z-80 page). I also came across the "Silicon Zoo" in my Firefox bookmarks list. It's a site full of "chip art" - little doodles that chip designers sneaked into the chip masks. <http://microscopy.fsu.edu/creatures/> There are also a few more on the Chipworks site - URL: <http://www.chipworks.com/gallery/gallery_home.asp> Later. -- Phil. | Acorn Risc PC600 Mk3, SA202, 64MB, 6GB, philpem(a)philpem.me.uk | ViewFinder, 10BaseT Ethernet, 2-slice, http://www.philpem.me.uk/ | 48xCD, ARCINv6c IDE, SCSI ... Let's organize this thing and take all the fun out of it.

Differences between TI-960B and TI-980B

by aek＠spies.com

The 960 and 980 are completely different architectures. 980s are fairly conventional 16bit accumulator arch machines while the 960s were oriented towards process control. I have one of each.

Grid 1520

by mapleleafman＠gmail.com

Hi crew. Question about a Gridacase 1520. Is anyone familiar with these laptops? This is a 286, really good shape. It won't boot, dead as a doornail. The guy at the thrift shop told me it was working when it was brought in the day before, now I see that two (or one) chips are missing from under the flap in the top left right above the keyboard. I figure they were lifted between dropoff and my buying it. Any ideas if these chips, which I think are application roms, would prevent the thing from booting? If so, is there such a thing as a replacement available from someone here or elsewhere? The thing must have been the first Toughbook or something, and I'd love to see it working. Thanks for any info anyone can share. (does anyone still need a gmail invite? I have lots. ) Brian Mahoney

Importing binary files without removable storage nor non-bund led software (was: TKermitFTP

by RCini＠congressfinancial.com

This is the exact same method that's used to initiate the install of ADT, the Apple Disk Transfer utility that's used to get Apple II disk images over a serial link to a PC for archiving and use with emulators. I believe that DOS has something similar which redirects the CTTY device to COM1: (CTTY=COM1: or something like that). CTTY is the DOS shorthand for the console terminal (screen and keyboard). Obviously this works only in text-only DOS. -----Original Message----- From: cctalk-bounces(a)classiccmp.org [mailto:cctalk-bounces@classiccmp.org]On Behalf Of Pete Turnbull Sent: Thursday, January 06, 2005 3:19 PM To: General Discussion: On-Topic and Off-Topic Posts Subject: Re: Importing binary files without removable storage nor non-bundled software (was: TKermitFTP On Jan 6 2005, 9:30, Vintage Computer Festival wrote: > On Thu, 6 Jan 2005, Dwight K.

Microsoft were in a hurry to make DOS work for IBM, and there was simply no perceived need to add the functionality. If you look at CP/M-related and Apple ][ systems, you see they had (er, have) the same problem: no out-of-band way to signal end of file. Several versions of kermit for Z80 machines and Apple ][s therefore come with a little program to talk from a remote machine to the serial port, start debug or equivalent, and stuff an ASCII-converted copy of kermit over which debug then saves in executable format. I've still got the ASCII HEX files for an Apple ][. As far as I remmeber there are two ways to get Kermit-65 onto an Apple. The first way is to type "IN#2" to set he serial card as the input, and then on the remote machine give the command to send the main file. It starts with "CALL -151" to jump into the monitor, and then follows that with a series of lines like "E00:38 A5"... which cause those bytes to be stored in memory; then it calls the code it's just stuffed in, and that in turn loads a huge number of much more compact (no addresses, no spaces) lines, before finally issuing a "3D0G" to get back to BASIC. Ditto for the serial card driver's HEX file. Finally you type "PR#6" so output goes to the disk, and you EXEC the two HEX files to create the actual binary as a disk file. Easy ;-) The other way is superficially simpler; you type IN#2, transmit a small file which creates a BASIC program and runs it; that program receives and saves the two HEX files, and then tells you what to do with them. Seems slightly simpler, but actually takes a lot longer, as I recall. -- Pete Peter Turnbull Network Manager University of York

TKermitFTP

by dwight.elvey＠amd.com

Hi I'm almost sure I'd done this in the past to get something like laplink running on a remote machine. I suspect that the code specifically had no ^Z until the end of the file and it was just a minimum bootstrap program to load the rest. One could always edit the file by changing any ^Z to something else. Once on the new machine, just change them back. I do remember that the name of the file couldn't be .COM or .EXE. I think the copy from COM1: didn't work for those files names.

780 simulator project

by bob.supnik＠sicortex.com

I've finished, and am debugging, a VAX-11/780 simulator, with the goal of running VMS V1, early BSD releases, and other 'first VAX' code. There are a couple of critical missing pieces. In particular, I need 1) 780 PROM bootstrap contents. This was the 4KB of PROM located in the MS780 memory controllers. A binary dump would be sufficient, the simulator can dissassemble VAX code. 2) LSI11 console PROM contents. The LSI11 console ran out of a boot PROM. This is less critical but would help with understanding the fine details of the console-CPU interaction. Again, a binary dump suffices. 3) VMS V1 floppy kit. While early tape distributions have been found, the console floppies have not. The most critical ones are the tape restore program and the system bootstrap (VMB). Getting a 780 online required - booting the console from its PROM - loading the standalone tape restore program into the 780 from the console - running the standalone tape restore program to copy VMS from the distribution tape to a hard disk - loading VMB into the 780 from the console - using VMB to boot VMS Any help would be appreciated. The 780 simulator, in its current incomplete state, is included in the SIMH source distribution, http://simh.trailing-edge.com. -- Bob Supnik bob.supnik(a)sicortex.com VP Engineering Tel: 978.897.0214 x202 SiCortex Fax: 978.461.2444 One Clocktower Place Cell: 508.344.0398 Suite 100 Maynard, Ma 01754

Max is > 4MB (as with any 22-bit address bus). My 11/24 _uses_ the KT24 Mapping Module with the suggested MS11-PB, giving it 1MB of ECC Memory. I can guarantee, that this combination works :^) There's another board, I own: a MS11-LB (M7891-BB) with 128kb. But I suppose that it doesn't make much sense to put this one together with the MS11-PB. The Ms11-PB is certainly much faster than the MS11-LB. Unfortuantely, the National Semiconductor boards can't be used, they were built for a VAX 11/750... Currently, I have some problems to get this baby work. There is a strange malfunction: When typing in some letters or digits on the keyboard (VT420), the screen turns out some sort of random characters at the @-pormpt. It's very weird ! Sometimes, when I turn it off and on to give it another try, it becomes impossible to type something. The prompt is waiting, the cursor's blinking and the machine try to bootstrap, when pushing the boot-button, but I simply can't type in anything ! The grant und bus connections are closed. The terminal works perfectly on local mode. The "Clock" LED is on, in fact, never turns off, while the 1-LED (the one next to the Clock-LED) turns on when the PROM for the CPU diagnostic is loaded (@165004g). After that, both LEDs remain on. The Maintenance Card for the 11/24 isn't on the internet (at least, I didn't find it), and there, the LEDs functions are described. Could anybody give me some help on this ?

Kinetic's FastPath 4's

by dholland＠woh.rr.com

Hi, To re-iterate a CCTalk thread I found that was two years old, anyone got any documentation on one of these things? (I picked up one off of EPay cheap, in a vague attempt to get some networking into a IIgs) I've found this page here: http://www.walshcomptech.com/fastpath5/ That site had a little software for the FastPath 5, however, I've not had the opportunity try it out. (None of the Apple boxes I have access to have any sort of network in them. Powerbook 540c, and of course the IIgs.) So, anyone seen any other documentation on the things, on the web? Thanks! /me goes back to googling for doc's... David

TMS9980/9901

by river＠zip.com.au

Hi, Does anyone know where I can get TMS9980 and TMS9901 chips from? They're never on eBay. I tried a chip broker who had a large stash, but he wanted 200USD per chip! I'm trying to get my old TM99/U89 system going and the 9980 and 9901 chips have corroded badly and lost a leg or two. I've been told the 9980 was in some old pin-ball machines, so I'm currently hunting down these sites to verify this. seeyuzz river

Slightly OT: DOS programs in Win XP

by news＠computercollector.com

A while ago I asked if anyone on the list could help me get AutoCAD 12 for DOS. Several people came through and I now have a copy. Thanks, everyone! As expected though, it doesn't work and play nicely with Windows XP. I was hoping that just running it through a command prompt window and giving that giving the Win 95 compatibility attribute to the acad.exe file would make it work. It didn't and I got a strange error message: "Phar Lap err 74: Can't use -REALBREAK under this version of DPMI" So I Google that and found a few threads like this one: http://discussion.autodesk.com/thread.jspa?threadID=314 Apparently it's just not possible to run Acad 12 in 'real' DOS in XP. I already knew XP's prompt is nothing close to real DOS, but I was hoping to find a way to trick the program, or a way to emulate DOS perhaps. Anyone have a clever solution to this? (I do have a suitable second PC to install real DOS on, but I'd rather not have to dedicate a whole system just to use one program.) ===== Tell your friends about the Computer Collector Newsletter! -- It's free and we'll never send spam or share your email address -- Publishing every Monday(-ish), ask about writing for us -- Mainframes to videogames, hardware and software, we cover it all -- W: http://news.computercollector.com E: news(a)computercollector.com -- 628 readers and counting!

NICE hp box on epay

by jwest＠classiccmp.org

Hey HP fans... Check out item # 5154313481 on ebay. I have a stash of these, but none I want to get rid of yet. Evenso, I was tempted by this one. It's a 2100A, looks to be very good condition, and stuffed with a lot of really nice cards. The seller put up some really nice photos of the all over the unit and you can enlarge all of them to read the fine print on all the card handles. That system is pretty decked out... 32KW core, several 8-bit dup reg boards, several CRT interfaces (I'd like one of those). 7970 Mag tape, 13210 (7900A) disc controller set. Very nice. If you're not an HP fan, you really should check out the front panel pictures. Gorgeous - but then I'm biased :> Jay West

Speaking of eBay

by dwight.elvey＠amd.com

Hi It is true that capacitors can have nonlinear effects. In most cases, the design is such that these effects are vary small and only in cases where the capacitor is used as a filter parameter that has a sharp cut off, does this have measurable effects. This means that blindly replacing all the capacitors is just plain silly. Speaker wire is another interesting one. All wire has impedance ( DC and AC effects ). No wire will ever be the right impedance for an 8 Ohm speaker. Different speakers are effected differently by the speaker wire. I've done some AB test with wire and for at least two speakers, I looked at. I could hear no difference between 6 feet of 12 ga. appliance cord and woven special speaker wire. I doubt my hearing is good enough today to repeat such test but at the time my heard was better than average, being able to clearly hear TV horizontal outputs from any TV across the room.

Greetings, list! In my quest for the perfect PaperClip PC, I have finally managed to find a decent snapshot of the book cover: http://pictures.abebooks.com/EVIANS/402158968.JPG I was somehow under the impression that the cover was a dull RED, not light blue; can anyone who has a copy clarify this issue? TIA, -dhbarr.

Slightly OT: DOS programs in Win XP

by RMeenaks＠OLF.COM

Hi, If you want to do that, there is a better way (if you want to write the C code for it). I use IO.DLL which allows you to do inp, outp in user space. There are several of these types of DLLs, but this one seems to be popular: http://www.geekhideout.com/iodll.shtml This allows you to port those old dos programs directly over to XP as a console program. Very handy.... Cheers, Ram -----Original Message----- From: Dwight K.

I'm not sure it matters what the license said. Adobe tried the trick of making it against the license to transfer a copy of their software to a new owner.

Reviving old hard drives

by dwight.elvey＠amd.com

Hi All I can say is that those were the words from the actual engineers that were working on the problem. Yes, I do believe the disk had coatings but they were dry lub ( like Teflon ) and none flowing. Anything that would flow would quickly destroy the disk. Any lump on the surface would cause the head to bounce. Anything that flowed slowly would cause a lump. Since this doesn't happen, it couldn't be. A smoke particle is a lump. Dust is usually so large that the head knocks it out of the way. Still, they said they solved the problem by making the surface a little less smooth. If someone opened a disk and saw lube on the surface, that disk had a failed bearing seal.

Available: BA23 skins x 2 sets (UK)

by listmailgoeshere＠gmail.com

I have 2 sets of BA23 "skins" (the outer plastic covers) available. One is complete and undamaged (except for the property marking described below) - has both side panels, front cover, back cover, and the base "foot". The other has everything except the back cover, and the "foot" on this one has a chunk missing from the middle of one edge, maybe about 4" long. Both of them have the name of the organisation they came from marked on the front panel (under the opening for the drives) using the "SELECTAMARK" system (blue dots which spell out letters in a dot-matrix-style font). This can be removed with glasspaper, or if you don't care you can of course just leave it. I suppose this only really matters if you want the covers for display/museum purposes. Best offer (to me by private mail) by the end of 21 days takes them. Your offer can be from "nothing" upwards - I don't mind if these go for free, but if they're worth more then obviously I wouldn't mind a few drinking vouchers ;) You must pay shipping or collect in all cases. Ed.

> Anybody have a stupid DOS trick for importing binary files > over a com: port? MS DOS came with a program to do that. I dont' recall the exact name, but it was something about a server (check the DOS directory it will probably spring out at you). You had to setup one side as a server and one as a client. I don't recall if you had to do it at boot time or not (I had boot disks setup for it, so I always did it at boot, but that might have just been the way I set it up). I used to use it over parallel, but I'm pretty sure it worked over serial as well (I think I did parallel simply because it was faster). If you can't find it, let me know and I'll dig up the name. -chris <http://www.mythtech.net>

Slightly OT: DOS programs in Win XP

by melamy＠earthlink.net

win2K and on will not allow any hardware direct access to hardware. In the DOS days, programs "talked" directly to display cards to bypass BIOS or expected to load their own memory manager (that is the Phar Lap error you are receiving). There are a lot of console programs that will work just fine on XP as long as they access normal BIOS and DOS system calls. AutoCAD is not in that category... best regards, Steve Thatcher -----Original Message----- From: Computer Collector Newsletter <news(a)computercollector.com> Sent: Jan 3, 2005 11:58 PM To: cctalk(a)classiccmp.org Subject: Slightly OT: DOS programs in Win XP A while ago I asked if anyone on the list could help me get AutoCAD 12 for DOS. Several people came through and I now have a copy. Thanks, everyone! As expected though, it doesn't work and play nicely with Windows XP. I was hoping that just running it through a command prompt window and giving that giving the Win 95 compatibility attribute to the acad.exe file would make it work. It didn't and I got a strange error message: "Phar Lap err 74: Can't use -REALBREAK under this version of DPMI" So I Google that and found a few threads like this one: http://discussion.autodesk.com/thread.jspa?threadID=314 Apparently it's just not possible to run Acad 12 in 'real' DOS in XP. I already knew XP's prompt is nothing close to real DOS, but I was hoping to find a way to trick the program, or a way to emulate DOS perhaps. Anyone have a clever solution to this? (I do have a suitable second PC to install real DOS on, but I'd rather not have to dedicate a whole system just to use one program.)

It is worth something to me, but at the moment my budget is rather tight. I didn't mean to 'whine' about it, I was just excited to see such a complete piece for sale, and was surprised when you bought it. I didn't mean for you to buy something you didn't want. I'd say the complete documentation (the stuff in the binder) is worth around $60 to me, but I don't have any extra money to spend right now. In about a month I should have enough. I'll e-mail you then.
