trying to design my first micro- looking for "prior art" (6100and6809)

by compoobah＠valleyimplants.com

Sounds like I'm back with 6809 as being easier to work with. I'll sit down with what I've got here and see what I can come up with (I'm more interested in designing than just having a "soldering skills test"). Scott

uIP TCP/IP stack for MSDOS

by jba＠sdf.lonestar.org

Hey everyone! I finally got around to posting my port of the uIP TCP/IP stack to MSDOS systems with FOSSIL serial drivers. I completed this port a while back for display at VCF Midwest 1.0. I've updated some of the source code to contain the necessary copyrights, and I've made it available on my webpage: http://jba.freeshell.org/uip.html This port of the stack contains only a web server that can be run through a SLIP connection. The software was only tested on a DEC Rainbow 100, but it makes no hardware calls, instead relying on the FOSSIL driver for serial access. It should run on any MSDOS-compatible OS with a FOSSIL driver in place, including some of the more exotic systems. I do plan on updating the port to work with uIP 0.9, the current version of the uIP TCP/IP stack. After the upgrade, it should work with more clients and servers. I hope this is moderately helpful or at least interesting to some! -Jeff Armstrong jba at sdf.lonestar.org SDF Public Access UNIX System - http://sdf.lonestar.org

IBM DASD and Unit Record equipment on eBay

by brian＠quarterbyte.com

Norm and I are looking at getting the CPU. We got a virtually identical setup of all the other stuff this spring, but with a 4331 CPU. The 4381 is a lot better. If anyone else is hot to get the CPU let me know so we don't get into a tussle over it :) Brian

Non-random numbers (SIMH PDP-8)?

BASIC+2 (on the PDP-11): .help/bp2 fun buil rnd The RND function returns a random number greater than or equal to zero and less than one. Format real-vbl = RND Example 990 R_num = RND .help/bp2 sta random The RANDOMIZE statement gives the random number function, RND, a new starting point. Format { RANDOMIZE } { RANDOM } Example 45 RANDOMIZE --- I know of other BASICs as well who used that convention. > Yep, just checked. RND(1) seems more typical. There are a few basic > dialects listed on my Ahl's simple benchmark page... I'd say it might be a bit hasty to say so. Many of those dialects you have there are really the same. Very many Micro computers used Microsofts BASIC. I wouldn't call that different dialects. Anyhow, I grabbed the VAX BASIC version and compiled it on a PPD-11 with RSX and BASIC+2. Here is the result: .run rand 340 iterations. .588235E-01 seconds per iteration Accuracy .685425E-01 Random 6.23425 Johnny -- Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt at update.uu.se || Reading murder books pdp is alive! || tryin' to stay hip" - B.

Wow.... opening bid was $100 and it was bid up to $500! I guess these old larger format pen plotters are still in demand! -- "The Direct3D Graphics Pipeline"-- code samples, sample chapter, FAQ: <http://www.xmission.com/~legalize/book/> Pilgrimage: Utah's annual demoparty <http://pilgrimage.scene.org>

Essential for polycarbonate and some types of Perspex. If it's the type with a fan, it's also good for the actual thermoforming, though you can also use your infrared heater for that. -- Pete Peter Turnbull Network Manager University of York

dovebid.com experiences?

by legalize＠xmission.com

Hi, does anyone have any experience with this online auction house? It looks like they mostly liquidate new equipment, but since the lots aren't listed until shortly before the auction opens, its hard to tell. Currently there's gobs of Sun E250 servers sitting at no bids with a minimum bid of $50 in Hayward, CA. -- "The Direct3D Graphics Pipeline"-- code samples, sample chapter, FAQ: <http://www.xmission.com/~legalize/book/> Pilgrimage: Utah's annual demoparty <http://pilgrimage.scene.org>

Doesn't *anyone* have those 11/24 switch settings?

I have the system installation manual for the 11/24, but not where I'm sitting right now. I'm in digest mode, so I saw another header saying you already got it now, so I'm not hurrying on this, unless you send me another letter about it though.
