Well, I've heard many complaints about it, but I don't know what's
actually wrong with it, and I doubt I would understand if you told me. But
try anyway.
---------------------------------- >>
the way i understand it is that the pc interrupt system is edge triggered. i
think an interrupt went low only momentarily and if the machine happened to
overlook that interrupt, the machine would hang. on the ps2 models, the
interrupts on that are level sensitive, meaning that an interrupt request goes
low and stays low until it's satisfied. there is much less possibility of
level sensitive interrupts going unnoticed. ps2 models can also share IRQs.

Netscape has been available for download since at least vers=2. I don't
recall if i ever used version 1. heck, don't even know if there was a 1.

It was free for educational use (including home users) since at least 1994,
when I obtained version 2.something to replace the 1.01 that was on the
machine I was using then. IIRC, you were supposed to register it, but
there was no fee if you "signed" a declaration that you were in education.
I remember that the download was a massive 2MB and I had to split it
across two floppies...

Hi Joe,
Where is this scrap place you are talking about?
I know there are a couple of them here, never thought of looking there
before. Do they sell you the stuff as scrap ?
Or by the pound..?

Last time I checked on it, Netscrape Communicator was somewhere around $45
in the stores, where IE was free with about 10 different programs.
Netscrape came with the program that I bought, and it was a stripped version
that kept wanting me to sent $30 to Netscrape, and it stopped working after
6 months (date stamped). Let's see...IE only wanted me to sign up with MSN
once, and that was because I used an MSN trial CD to install it. First time
I ran it, I simply went into the settings, set the start page as blank, and
Bingo! no MSN. If you ever noticed, When you got Netscrape on an AOL CD,
it _really_ wants you to sign up for AOL AND pay $30 to them.

Seems to me that I remember an old version of IE that was for OS/2, too.

How is it then I got it for free off their site?
AS to which is better, neither when broken and both when working with one
little gotcha... If the site uses netscape tools to gen interactive queary
pages I've found IE to be univerally broken and netscape is required! Oh,
same for IE tooled pages.

Basically, it's coming from everywhere. I think it's mostly the enamel
burning off the traces, and from the melting Z80.

Huh? The solder melted in a lot of the places, and the paper clips stuck to
it. There's a lot of fried traces, too. Instead of trying to fix it, I'd
be MUCH better off just finding another board.

Ah, not really. the production start dates for both chips are within two
months. The 8088 was for those smaller (non PC!) apps that needed the lower
cost of 8bit wide everything but still needed more performance than the 8085
could deliver and also gave a migration path for those that grew out of the
8088.
The 8088 and 8086 were both second sourced before IBM did the XT. thats
based on my non-preliminary intel data books from late 78 and early 79.
NEC was making reverse engineered parts by 81! Even the V20 was in 81.

I know this is somewhat off-topic, since OS/2 2.0 is too new, but does
anyone know where I could get the software to get it to connect to the
internet via PPP? I installed it, and it's a fairly nice system.

Yes. I've been using a 386DX with 128k cache with Win3.1 and Netscape 3.0.
Doesn't seem significantly slower than my friend's P90 with W95. Sometimes
Netscape crashes with some .JPG files (GP fault in the VGA driver) and I
have to start over.
Haven't tried much newer, it doesn't seem right to require a 300MHz
processor and 64MB ram to mostly read email, much less type mail messages!
I did adjust several things, like remove smartdrv's "buffering" for the HD, etc.
