<On the 1802: Did COSMAC VIP actually stand for something?
COSMAC VIP was a packaged game machine that could also run simple
programs using a very tiny interpreter (512 bytes) called CHIP-8.
I have the manuals for one along with other 1802 docs and a few 1802s.
Strange chip but made a fair stack machine.

With this news, one of my first thoughts was that if Compaq intends
to make money by selling its servers to DEC customers, software
emulators of old DEC systems suddenly become very, very important!

Well, here are the genuine system requirements for Windows 3.0 -- I'm pretty
sure these are correct, since I wrote this KnowledgeBase article back in
1990 :)
If you know how to get the secret credit screen, you can see my name on

Let me know if you have any other ancient Windows questions.

Windows 3.0 Modes and Memory Requirements [win3x]

SUMMARY
=======
This article contains information on the processor and memory requirements
for the three different operating modes of Microsoft Windows version 3.0.
These modes are real mode (similar to Windows/286 versions 2.x), 286
standard mode (also known as 286 protected mode), and 386 enhanced mode
(also known as 386 protected mode).
MORE INFORMATION
================
WIN.COM automatically starts up Windows 3.0 in the proper mode for the
configuration. However, Windows may be forced into one of the three
modes through the following command-line switches:
Switch Mode
------ ----
WIN /R Real mode
WIN /S or WIN /2 Standard mode
WIN /3 Enhanced mode
Notes
-----
1. All numbers below are approximate and may vary widely depending
on the configuration -- for example, Windows device drivers chosen,
DOS version, display adapter, etc.
2. 128K of extended memory is recovered from shadow RAM usage on
COMPAQ 386 machines.
3. Memory requirements take into account memory that can be recovered
from SMARTDrive (down to the minimum cache size specified).
Real Mode Requirements
----------------------
1. The requirements for WIN.COM to automatically start up in real mode
are as follows:
a. 8088 processor or above
b. 384K of free conventional memory (393,216 bytes reported by
CHKDSK)
2. The actual real mode requirements are the same as above.
Standard Mode Requirements
--------------------------
1. The requirements for WIN.COM to automatically start up in standard
mode are as follows:
a. 80286 processor or above
b. 192K of free extended memory
c. HIMEM.SYS loaded in the CONFIG.SYS file
2. The actual standard mode requirements are as follows:
Standard mode conventional/extended memory requirements are
mutually dependent and are not fixed. A typical installation
requires a minimum of 128K free at the DOS prompt to run standard
mode, assuming sufficient extended memory is free. Standard mode
requires between 384K and 512K combined conventional and extended
memory to run (approximately).
For example, if only the minimum 192K of extended memory is free,
approximately 322K of conventional is required to run standard
mode. However, if available extended is increased to approximately
208K or greater, only 128K of conventional is required. This
example is intended to illustrate that the memory requirements are
an interrelated, variable issue.
Enhanced Mode Requirements
--------------------------
1. The requirements for WIN.COM to automatically start up in enhanced
mode are as follows:
a. 80386 processor or above
b. 1024K of free extended memory
c. HIMEM.SYS loaded in the CONFIG.SYS file
2. The actual enhanced mode requirements are as follows:
See notes for standard mode, above, relating to the
interrelationship of conventional/extended requirements. A typical
installation requires a minimum of 182K free at the DOS prompt to
run enhanced mode, assuming sufficient extended memory is free.
Enhanced mode requires between 580K and 624K combined conventional
and extended memory to run (approximately).
Note that enhanced mode is able to start up in low-memory
situations only because it provides virtual memory support;
although enhanced mode may run in such situations, it may be
extremely slow due to the large amount of disk swapping it must
perform.

I might be mistaken, but I somehow recall that someone said that
it was possible to run windows 3.0 on an XT???
A buddy of mine gave me an unopened box of v3.0 but the back
says it requires a 286.
So whats the deal?

Well, the sticker on the top says that it is version 3.00(3.5) but it does
say that it will support CGA or Hercules so I might be in luck.
Had an AT&T 6300 sitting around and thought it might be neat to run
it on this. It's got an old Micropolis 40 megger on it thats pretty much empty.
(Does anyone else think that the sounds made by old MFM drives is really
cool??) On a different note, the monitor I have is an AT&T model
as well that "shows up" as a CGA but looks a hell of a lot like EGA.
Is it some kind of "Super CGA" that wasn't really supported by anyone?

Speaking of polygonical manholes, does anyone know where to get a copy of
turtle logo for older macs? Or, perhaps even better, a cartridge version
for one of the 6502 machines (Atari, c64, etc.)? (This is for my niece who
is probably about ready to at least watch logo pgms.)

You may have triangular manholes (and, I assume, covers), but I disagree
with the statement that they won't fall in. (Mind you, they may not be
*likely* to, but that doesn't mean they won't.)
Consider any regular (is that the right term?) polygon (i.e., all sides,
angles are equal).
For an odd number of sides: imagine a line from an angle to the midpoint of
the opposite side. Imagine a second line, from that same angle to either
end of the opposite side. You've just created a right triangle (imaginary
lines, half the opposite side) wherein the first imaginary line *must* be
shorter than your second line. Put your first line parallel to the ground,
line up the manhole vertically above the corresponding second line on the
manhole, and drop.
For an even number of sides: Do the same thing, only the reverse (opposite
angle and connected side, etc.)
Oh, make sure there's no one down below before dropping *please*

It is a Commodore PET GPIB (HPIB) cable. Most PETs didn't have the
standard GPIB connector (the 8032SK being the only exception I can call
to mind) but had a 24 pin edge connector instead. The pinout is the
same; pin spacing is 0.156 inch.
The "Parallel User Port" (some useful lines from the 6522 VIA plus some
diagnostic type stuff and video out) was a similar connector with
keyways in different places. The 8032SK used a GPIB type connector for
this as well, which I found very annoying when trying to connect one to
a friend's BBC micro... but I digress.
(BTW can anyone confirm: is 0.156 inch _really_ 0.156 inch or is it 5/32
inch?)

<Deal is, you can't run Windows 3.x on any processor that doesn't have
<protected mode. I think the last Windows you could run on an XT was 2.1
Wrong, it was 3.0 and I'm doing it. It was loaded from my diskset so
there is no doubt. Now if you meant it would be slower than sludge
no argument.

As best we could figure it may be a later version kit that does not have a
MDA/herc driver or some such. My copy of 3.000A does run on XTs and is
installed on a DTC turboXT so it runs in my lifetime. I didn't say it
would be fast. FYI a fast disk really helps.

It's not documented and MS never mentioned it, but yes it will work on an
XT.
