Jim; did you get my previous message about how we should settle up on the shipping on the 2nd platter? I think there was also another question in that particular email to you, but I don't recall at the moment. Just to want you to think I'm a deadbeat!

IBM/XT Y2K Compliancy

by peter.pachla＠vectrex.freeserve.co.uk

Hi Roger, >Are the IBM/XT, IBM/AT and PS/2 computers hardware Y2K >compliant? According to a recent thread in the PS/2 newsgroup, all PS/2s should be broadly Y2K compliant, though some machines may need their times resetting on 1/1/2000 depending on the OS they're running. PC/XT class machines generally have no clock hardware in them as standard. DOS/whatever simply use a regular interrupt to update a software clock, so you need to know if the OS you're using is compliant. All AT class machines have a clock chip inside, a 14818 (or something similar, I forget), or an emulation of one. The chip only stores the last two digits on the year, so it will correctly roll over to "00" for "2000". However, what your operating system will make of that is another matter.... In each case, it all boils down to your OS. The easiest way to find out if it's compatible is to set your clock to a few minutes before midnight, December 31st and wait and see what happens when the time rolls over past midnight.

Novel/Eagle NE1000 & NE2000 ethernet cards (& others)

by jeff.kaneko＠juno.com

3Com's 3C300 was their 1st PeeCee NIC, it was a big card, contrast to their later 503's and 509's which had a much higher level of integration. I'm told 3Com's very first product was a MultiBUS NIC (of which I have two). Can't seem to find the docs for it, though. OKay, for 100 bonus (bogus?) points: What were the three Com's of 3Com?

Novel/Eagle NE1000 & NE2000 ethernet cards (& others)

by mark_k＠iname.com

Hi, Recently I picked up a load of Ethernet cards (some nicer PCI bus mastering ones -- excellent for Linux etc. -- are for sale, btw). NE1000 & NE2000 --------------- Amongst these are what I believe to be Novell/Eagle Technology NE1000 and NE2000 cards. Now, I have found jumper info for these two, and got them to work on a simple two-computer peer-to-peer Windows 95 network. The NE2000 works fine. The NE1000 seems to also, except when trying to copy a 40MB file to the computer which contains the NE1000, it hangs part-way through (this happens every time). Either this is a fault, or simply a deficiency -- perhaps the other computer is sending data too fast for the NE1000 to keep up, and it gets confused? Anyway, I'd like to get the official/original drivers, documentation and diagnostic programs for these cards. I looked at http://www.novell.com/, but there seemed to be nothing there. Eagle Technology don't seem to exist any more, or don't have a web site. There appeared to be some NE1000/2000 stuff at ftp.microdyne.com, but it turns out that this is for the NE2000+, whatever that is. Does anyone know if there is some other Novell web or FTP site that has info on their ethernet cards? Here's some info about my two cards. NE1000: 8-bit ISA card. Novell warranty label has date code 2789. Text silk-screened on PCB reads BD.# 738-160-001 REV. C ASSY.# 810-160-001 REV. C NE2000: Warranty label on rear has data code 5092, says manufactured by Eagle Technology. Text silk-screened on PCB reads BD.# 738-149-002 REV. C ASSY.# 810-149-002 REV. C IBM Ethernet card FRU 48G7170 ----------------------------- I also got a couple of these. They seem quite nice, having BNC, RJ45 and AUI connectors plus two indicator LEDs. A label on the PCB reads FRU 48G7170. Both cards have boot ROMs fitted, on which a label reads 60G3312. If anyone need to make a boot ROM for this type of card, I have dumped the data from them. This card is configured using a DOS setup program. The only jumper on the card is labelled J5. Does anyone know what the purpose of the J5 jumper is? Oldest PC ethernet cards? ------------------------- Drifting slightly back on topic, which companies made the earliest ethernet cards for PCs? How much did they originally cost? -- Mark

What did you change in the system that caused it to go from "auto boot to DL:" to its current behavior? A break in backplane continuity can make it look like the RL11 isn't present in the system, and that'll drop you out to the console prompt. -- 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

A pointer to classiccmp from an .epa.gov site

by svs＠ropnet.ru

G'day, While searching for existing searchable archives of classiccmp, I found <URL:http://epainotes1.rtpnc.epa.gov:7777/r10/owcm.nsf/recycle/pcrecycle>: [...] Computers and electronic equipment that still work, but are obsolete, may be suitable for reuse. Check with local schools, training institutions, or non-profit organizations to find out if they accept donations of this type of equipment, or use the list of recycling options to obtain the names of organizations that will repair, consolidate, or reassemble the equipment before donating or selling it. There are a growing number of hobbyists interested in very old computers. Any machine that is "so obsolete that it can't be reused" may actually be of great interest, and potentially worth much more than its value in scrap metal. Older is better here. There is a "classic computer" mailing list at classiccmp(a)u.washington.edu , and more info can be found at any of these web pages: http://www.yowza.com/classiccmp/faq.txt http://www.cs.unc.edu/~yakowenk/classiccmp/ [...] -- Sergey Svishchev -- svs{at}ropnet{dot}ru

Looking for an RK05j User

by mcquiggi＠sfu.ca

Hi Group: Having gotten the 11/45 in my basement operational :-) , I'm on to the next step, the attached RK05. As I start towards the next milestone I am wondering if there is anyone on the list that has a working RK11/RK05 combination going. I will likely have questions!

Question on booting PDP-11/44

by healyzh＠aracnet.com

Am I correct in assuming that when a PDP-11/44 finds that it has more than one controller in it that it can boot off of, that it drops you into the monitor, so you can select the device you wish to boot from?

New arrival... (s)?

by allisonp＠world.std.com

<> Something about the unit suggests that the previous owner ran CP/M on it <> but as to just what that clue is I will leave without explaination. (tha <> way you have to look at the pictures) <G> Whyy not all the needed items are there... at least 20k of ram, IO, a disk system and the 8080 or z80 cpu. Common crate to run cpm on as it was solidly built. <> Hmmm... I wonder if there is a copy of IMSDOS buried around here <> somewhere??? <BG> Good luck! Allison
