OT:Macworld - Will anyone be there, Think we can meet?

by ron.hudson＠sbcglobal.net

Will any of you be attending Macworld in SF next week? Decide a place and time inside or nearby? I plan to attend at least the first and last days, other days optional depending on how my cash holds out.

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.

DEC was very good about using EIA-232 (and EIA-423 and other related interfaces) the way it was supposed to be used, not the way the pee sea world uses it. MS

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

To make binary transfers work, they'd have had to change the already-existing methods that they had. To prevent them, they only had to add an error message and add one more case to a test for a command-line switch. -- Pete Peter Turnbull Network Manager University of York

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
