I am trying to help a friend of mine get the second serial port on his DTK I/O Plus II card working and it does not want to cooperate. The documentation is no help at all. As an example, it says 'The serial port can be changed to COM2 from COM1 by moving jumpers.' but does not say what jumpers to move!! :-(  There are 2 banks of jumpers. The first one is labeled as follows: C1 C2 S2 P2 P1 G  The second bank is labeled "IRQ" and has the following labels: 5C 5S 4 3 3S 2C 2S  I have determined that the C1 & C2 jumpers tell it to address the first serial port as COM1 or COM2. The P1,P2 jumpers tell it to use the printer port as LPT1 or LPT2. I am guessing that the "G" enables the game port and the "S2" SHOULD enable the second serial port, but I can't get it to work. I have tried numerous setting on the IRQ bank without success. I assume that this bank must tell the card which IRQ's to use for both ports, but I don;t know how.  Any suggestions would be greatly appreciated!!  EBD --  Elliot Dierksen   "Is that a real poncho... I mean is that a Mexican poncho or                    is that a Sears  poncho?

I am looking for good add-on font cartridge for HP LaserJet II. I found in PC Magazine article IQ Enginnering and Pacific Data Products are well-known maker of cartridge for HP LaserJet series. But I couldn't find the model name of these products.  Any suggestions please.  Thanks in advance,
Does anyone have a manual for an Artec 14" NI monitor?  I need the specs.  Thanks.  Rob Malouf malouf@csli.stanford.edu
They are actually 72 pin. They come in 4, 8, 16, and 32 with 64s soon If you are interested in 4s or 8s, I may be able to help. Please call 415-324-2881 after 4:00 pm pdt. I may be interested in a trade.
I would like to thank all those people who responded to my post.  I  would, however, like to clear some things up.  My tape drive is *external*. Also, the connector on the back of it is of the male DB-37 pin variety. As a result, I cannot easily find a cost-effective solution to use the drive.       Any advice will be greatly appreciated.  I would prefer email.      Thanks!

The --VERY VERY FIRST-- thing you do is make sure that --ALL-- files on the floppies that you can currently read in the drive, which aren't already on your HD or another floppy (if you have -two- floppy drives) get copied to your HD (and/or to a floppy in your other drive).  If you don't do this before fixing the alignment problem you have kissd those files goodbye.  (Well, you can -try- to re-misalign the drive back to read your floppies, but don't count on be able to do so!)  Generally, head alignment is something I'd only trust to a good repair shop (though there are/have been DIY guides).

I think there are several reasons :-  50MHz motherboards are harder to get right 50MHz need a fast L2 cache - 12-15ns is a good idea 50MHz needs to be slowed down to make a compliant VESA bus 66MHz DX2 chips are faster for a lot of things   With a good, fast L2 cache a DX2/66 is going be be faster than a DX50...

I'd appreciate any advice about a video card for my system:  486-33 DX, 16 mb of ram on a Novell 3.11 network Monitor:  NEC 4FGe, capable of 76 Hz vertical refresh rate  Major considerations:  I expect I will work mostly in windows, but with some DOS applications and I would want decent speed in DOS.  I do mostly word processing, database and communications--not much intensive graphics.  With a 15" monitor, I expect I will work mostly in 800X600 and 256 colors seems plenty, but I'd like like the image to be sharp, fast, and rock solid.  Other considerations:  I sometimes run a Unix clone (Coherent) and I understand that some companies (e.g. Diamond?) don't encourage the third-party development of drivers.  I might move to OS/2 if I decide I need better speed and reliability than I get with Windows for my database work and multitasking.  I don't have a local bus motherboard--I'm not sure how much to invest in an ISA video board (versus getting something less expensive now and upgrading to local bus later).  I like buying things from companies that treat their customers well.  If you have any advice for me, I'd love to hear it via email or post.  Thanks.
Howdy,  I recently upgraded the original BIOS in a Compaq Deskpro 286/12 with a Phoenix replacement BIOS, in order to support an IDE hard drive, and a high-density 3.5" floppy.  I assumed that this would be a plug-and-play procedure, but I have encountered a problem that Phoenix and Compaq are unwilling to admit responsibilty for, and I was wondering if anyone else had seen it.  Everything is hunky-dory except the 3.5" floppy, which will read, but NOT WRITE diskettes.  Any write attempt merely corrupts both FATs.  I have tried everything I can think of.  Any takers?
Hey folks.  Is it possible to short out your CMOS chip?  I think mine is fried. These are the symptoms...  I have to do the following to get my computer (a Gateway 486DX33) to boot...      Turn the power off      Disconnect the battery to the CMOS chip      Turn the power on      Get into setup upon getting the CMOS configuration error      Set up the CMOS      Exit the setup with [F10]  (phoenix bios)      Ignore the diskette 0 seek error and press [F1]  The computer then boots normally.  Both hard drives are accessible but the floppy drives are not.  I can back up over the network and such, but if I need to reboot, I have to turn off the computer and repeat the steps above.  If I simply <Ctl>-<Alt>-<Del>, the computer hangs after the memory test.  Does this sound like the CMOS chip is fried?  Can I buy another one? Where?  Thank you for your kind attention.  john
I have a Gateway 4DX-33V with my 3.5 inch floppy as drive A.  I accidentally discovered that if a have a floppy from ONE particular box of diskettets in the A drive when I boot up, rather than getting the "Non-system diskette" message, the machine hangs and the CMOS gets overwritten (luckily, Gateway sends a print of the standard CMOS settings with their systems).  This only happens with a box of pre-formatted Fuji disks that I have, no other disks cause this problem.  If I re-format one of the Fuji disks, the problem goes away. I did a virus scan (scan v1.02) of the disks and found nothing.  Anyone have any idea what is going on here?  Hardware problem?  A virus that can't be detected?  The system reading in garbage from the boot sector?

Very possibly, but if it's still going to be backwards compatible with the ISA bus, it's going to be the same tripe that the current EISA implementation really is.  	From what I've seen, the PCI bus will just be a new 32bit 33MHz intelligent bus (ie, bus controller takes care of interrupts and the like, not jumpers...)  Hopefully it'll get somewhere up there with the AMIGA  Zorro III bus....  	VL Bus is a bit too much of a hack for my liking...

The motherboard manufacturer where I usually buy boards says >that they will have this problem fixed in about two weeks... >| Brian J Schaufenbuel  I don't see this as a problem with the chip-set (a mistake), I see this as something that was designed-in intentionally.  So it would seem that to enhance the design (from 24 to 32-bit EISA DMA) would require an update to the chipset.  An update to the chipset may  begat an update to the motherboard board design.  What I'm saing is:  The motherboard manufacturer seems to be passing this off as a simple fix.  In my mind the fix is a updated chipset from HINT  along with a possible motherboard layout update.  This is not simple. If I were you I would be cautious about this.  You might look into the Advanced Integration Research (AIR) VL/EISA motherboard.  All slots are EISA/ISA capable.  2 (or 3) of the slots are VL-bus capable.  The AIR people confirmed this board supports 'real' 32-bit EISA DMA (I called them).  Pentium/P5 (?) capable.  Less expensive than equivalent AMI or Micronics VL/EISA board.  Look in Computer Shopper (April '93).  The ZENON ads show the AIR mother- board.  A associate bought the AIR board and is pleased with it.  I'm attempting to get the local dealer to trade out the HAWK board for the AIR board.  Model number of AIR board (with 486-33DX) is B433EI2.  You can call Motherboard Warehouse (for example) for a price.  Phone #'s included below.  AIR                    (408)-428-0800 Motherboard Warehouse  (800)-486-9975
I've got a 386DX-40, 4MB and I'm using Windows 3.1. Sometimes I wondered why  Windows worked endlessly on my HD when I was doing nothing (execpt having lunch or something like that). Then I turned this virtual memory swapfile off, and Windows became quite faster, but now having less memory free. And so I'm still wondering, why windows is reading everything from virtual memory when the convertional is sufficient? Any common-sense-explanation is really appreciated.
Hello world,   I'm attempting to write an 8051 simulator on an IBM PC for teaching purposes, so that first-year elec-eng students can 'see' the workings of the microcontroller as it performs operations - logical ands, for example, being shown on a bit-by-bit basis (1 AND 1 = 1) so that the students can see that it's not really a mystical process, but totally logical, for example. Every instruction should show some 'working', and not just alter register/memory/port contents.   Does anyone know of any freely-available example simulation code, in Pascal or Modula-2, that would show me where I'm going wrong in writing my simulator? [I'm using Ayala's -The 8051 Microcontroller- as a reference - the simulator supplied with the package is overkill for simple teaching purposes, I feel, and there's no source code to help you roll your own.]   Please email me if you can help, or if you know of somewhere more  appropriate I should be posting this  - I rarely scan these groups.   Thanks,
My 486DX2-50 has 8MB of 70ns RAM and a Trident SVGA card. Sometimes I feel it runs very slowly, especially when running Windows.  I'm planning to buy an ATI Graphic Ultra + next semester. Is that all I need to get the problem solved? Is 70ns RAM chips too slow for my machine? Do faster RAM chips make a big difference?  I use CAD software on my computer as well. Do those up-grades good enough to speed it up a lot? Any one experienced the difference between ISA bus and VL bus(both with a graphic accelerator)?  (A SCSI controller may not be appropriate, since I may have to replace my hard disks as well. However, sometimes I do have huge files on my computer. Does    it really worth to use a SCSI interface? I can't spend too much on  it)  t he )    Any help will be appreciated. Thanks in advance.  Dennis dpang@uafhp.uark.edu  p.s. Man! I hate the stupid text editor.

I recently bought an AMD 386/40.  The motherboard booklet says the board is a "391 WB/H."  I have 4 1x3 simms on board.  The machine also uses a Super IDE I/O Card (model PT-604). (of course niether the motherboard or the I/O card booklet clearly state who the manufacurers are) I'm also using a Trident 8900C SVGA card.  	Anyway, that's all of the pertinent info I can think of. My problem is that the computer often freezes or displays "Parity Error -- System Halted" messages depending on whether I set the Memory Parity Error Checking to "disabled" or "enabled" in the setup of the bios (makes sense). Its AMI bios (so it must be an AMI board?).  	I just took it back to the dealer and they replaced all of the SIMMS but I keep getting the same error (more frequently now).  It all worked at the dealer and didn't start screwing up 'till I got home (figures).  	I've tried to take out all of the SIMMS and even re-inserted them in reverse order, making sure that the connections were solid.  	My suspicion jumps to this damn all in one HD controller/serial/ parallel/game-port I/O card, or to the motherboard (God forbid).  	CAN ANYONE HELP?
