I think that the Tandy 1000 was a CGA+ mode, with the idea being to provide 320x200x16 without a full EGA mode. So we have the old 640x200 standby here, too. Shane

This compiler is top-down, recursive descent, with an operator precedence expression parser... Small - C isn't worth much at all, I generally draw the line with enums and bit fields for C compilers. That means, the compiler has to implement *all* K&R C except enums and bit fields, or it's not worth thinking about. In addition, Small C's architecture is very, very poor, it actually parses using strcmp() ;-( Greg

The video card wasn't a problem since there's no monitor on any of the boxes in question, and the card's only there to keep the BIOS quiet. As I see it, the addition of both basic ethernet and a print spooler would allow an XT running ELKS to act as a print server as well, thus providing the first concrete application for ELKS, at least as far as I can tell...

Re: ELKS video drivers...
The MDA was a text only adapter. The HGC was the first to implement any dot addressable graphics with the mono hardware. FWIW, they both used the same CRTC (as does the CGA), they just program it differently. The 6842 I believe was the CRTC. --Perry > > On Mon, 17 May 1999, Greg Haerr wrote: > > > > 1.

It's not that the monitors wouldn't work, but that the mono cards origionally sold by IBM were text only (I'm sure there were other clones as well). I'm not 100% sure what the history of mono graphics is, but I know that Hercules was a very proular monochrome graphics adaptor...that's what my first computer had, and I suspect they were one of the first, and that many of the other monochrome graphics cards were simply made compatable with the Hercules.

RE: nanoX for ELKS
Al, I have completed running the nanox source thru bcc in 16 bit mode, and I've got the whole thing to compile. (I'm using my new version of bcc that compiles ansi c with no preprocessing...) In addition, I'm using a newly written ega/vga driver, written in C only, that also compiles. (It runs on DOS, I haven't got an EGA card in my elks box yet) I'm also using the std kbd driver, which uses termios. The mouse driver is still not implemented, but I'm working on one, and it should work. I have a few pertinant questions, and I'll be able to ship you a nano-X tree that will completely compile, and hopefully run on ELKS! 1. Does ELKS support select()? We need select() for the mouse_fd and keyboard fd, (serial and console tty) -OR- we can write a polling driver entry point... 2. Does ELKS support the various termios modes? Of course, no echo and ~ICANON are required. BTW, the nano-X executable on ELKS is 35k text and 6k data for a grand total of 41k!! ELKS graphical days are almost here... Greg
DesqView X
Hello ELKS list: I recently contacted Symantec, who to my surprise had purchased Quarterdeck recently, and inquired about the possibility of releasing source code to DesqView X, seeing as how it has been scrapped as a product and has no further commercial value to the company. My initial response was unfavorable, but I have no intentions of following up on it unless there is interest in it. I have attached the message I received below. Perhaps if they realize there is a little interest in the product still they may be willing to work something out. Meanwhile, I am one of the lucky few who owns DesqView X. Rather, a member of my family owns it, and although I'd like to keep it to play with it some, if he can sell it and make money from it he'd like to do it. It's version 1.1 and includes the original disks and manuals. He purchased it used a few years back, so it's not in mint condition if you want a collector's set but there's nothing missing as far as I can see. Let me know if you are interested, and we'll see if we can work something out for a price, etc. Looking forward to running ELKS with a mini-Web server :) -- Michael Hamblinhttp://www.utdallas.edu/~michaelh/ [EMAIL PROTECTED] http://www.ductape.net/ UTD Linux User Group Engineering and Computer Science Support x2997 Date: Wed, 19 May 1999 14:00:13 -0700 From: Custserv13 <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Subject: Re: Broken Link (Please include the URL of the problem and refer Hello Michael, Thank you for your message.

ELKS does not support older terminal > control interfaces like termio. > Great. Also, I have completed work on an EGA/VGA driver completely written in C. It uses the bios to switch modes only, and to get to the rom character set. This driver is currently running on DOS and linux, and compiling under ELKS. We're getting very close to graphics on ELKS.

ANSI C compiler for CP/M <--> Re: ELKS in AppleII+
Hello ELKS:ers and Amstraders! You are both interested in a C compiler for the Z80. I am crossposting this for all of you to read. (Maybe a few Amstrad people will also be interested in ELKS, an attempt to port linux to intel 8088 and later the Z80.)

Maybe you need CP/M or an emulator too, don't remember. I think this is a CP/M program, not a crosscompiler. It is free for noncommercial use. The CP/M issue should not be a problem. There are good CP/M emulators around, one of them run partly native and is essentially a "DOS downgrader", I'm told. I am letting the Amstrad people know this too, since they wanted to have a free CP/M C compiler. regards, Jakob

I have used this to get a completely stand alone harddisk elks system which takes about 4 seconds to boot! Unofortunatly it suffers from disk corruption due to fairly frequently being rebooted without shutting it down. Need to get fsck working better. Al
