TCPIP via ethernet under DOS? (I know that is possible...but!)

by hhacker＠home.com

Here are my thoughts on your need: -----Original Message----- From: jpero(a)pop.cgocable.net <jpero(a)pop.cgocable.net> To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> Date: Friday, May 21, 1999 9:51 PM Subject: TCPIP via ethernet under DOS? (I know that is possible...but!) >What s/w is needed to do the ip polling to gather in ip numbers on >outset of connecting to cablemodem? The s/w should consist of an interrupt driven device driver for the NIC, with any interrupts providing for input servicing. Now, this device driver should also provide the transfer of processor control to the IP layer. So, my suggestion is that you start with the NIC software. Under DOS you should also be able to implement the IP stack by extraction >from LINIX, or some other UNIX variant. Sure, there is bound to be a lot of modification work that you will have to supply to the code you "steal" from LINIX but, since DOS is a pseudo-lookalike for UNIX, it should work easily. William R.

Northstar Horizon Update

by allisonp＠world.std.com

<Note: BTW, I found a reference in the N* newsletters I have to the A2 <16k ram board being susceptible to noise on the bus. The A3 board, <which was available also as an upgrade to the A2, has alot better noise <immunity. That too! ;) I found the NS* I have was real cranky with a compupro Ram16, so for an experiment I pull the bus terminator from my CCS crate and all of a sudden all the crankyness is gone. This is something I never saw in my other NS* and the are identical save for mine was hand assembled by me and the one I'm working on is definately factory assembled. Allison

VCF 3.0 ANNOUNCEMENT: VINTAGE COMPUTER FAIRE!

In the real world, of course, someone who bought an IMSAI and populated it with only IMSAI peripherals was a fool. And it also leaves out the richness of computing that is (was) possible - take a look in the back of a late 70's BYTE and you'll see hundreds of manufacturers making a huge variety of S-100 boards. Yet any computers demonstrating this richness, so important in the early personal computing industry before the dominance of the PC-clone and the subsequent dull monotony of compatibles, lose points in this proposed judging scheme. Oh well, different strokes for different folks. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

First I changed the number of characters/ line from 32 to 64. Then I added a cassette "bit bopper" to it. I found the 60Hz line sync didn't work right, so took it out. Lastly, I added some graphics display in parallel to the characters. Now 20 or so years later, it doesn't seem to work, and the "original" ic's are all soldered in. -Dave

Northstar Horizon Update

Seems to me like last time I took one of the classes leading to "ESD Certification" the standard resistance for "primary packaging," which is what encloses and otherwise directly contacts the packaged items, was 1 MegOhm per inch. That is high enough resistance that you can't hurt yourself with inadvertent contact with the AC mains, yet low enough to dissipate static from the usual sources with little risk to the components.
