• CPU: Intel 386SL -  20 Mhz, RAM: 4 MB (32 MB Max)

• Graphics: 640 x 480 (monitor LCD 10” Back lit)

• Input/output: PMCCIA, VGA (proprietary connector), parallel port, serial port, pop-up mouse, keyboard, bus extender

• 1,44 MB Floppy

• 40MB HDD (My machine has 80 trough DoubleSpace)

• The built-in mouse with retractable trackball is located on the right side of the computer.

• One can lift up the keyboard to access battery and HDD

• The built-in microphone and speaker allow you to use it as a digital audio recorder. MPC business audio means it's easy to add vocal notes to documents, or send voice mail messages. I looks like a Wave audio device in Windows 3.1 - Maybe alle Windows apps/games can use it? I tried MOD4WIN but if could not find a playerback device.

• Original manual in English.

  • Press fn+7 on the numkey. The 7 is marked with a swiss army knife symbol. To enter BIOS setup. Can be done at any time - even in Windows.

  • If BIOS battery is unable to save changes, you will be sendt to "Build-in setup" or Emergency sentup. You have to fill inn all sections so be able to save the setting. If not all values are filles inn, the Save option will not appear when pressing ESC.

• I tried using the PCMCIA driver to access a CF card in the PCMCIA port, but I could not make it to work. Maybe the drivers that came with the PC are for CD-ROM?

• Things to do:

  • Install CF CARD - built inn HDD does not always spin up.

• Iomega Zip 100MB Paralell port version.

• Excellent not only to copy over programs, but also as a "harddrive" for running games and program directly from it. 

• The driver PalmZip is a lightweight driver that works on 8088 and above. Hardly uses any memory. The Zip drive is then a station (e.x. C:). Updated Feb. 2018

• Handy for copying things over from a modern Windows 10 machine.

• Note: it works in Windows 10, but is super slow to write data to ZIP discs. Using DoxBox increases disc write with about 10 times. 84 MB in 7 minutes.

• Intel i486DX2-50Mhz -490MB HDD (PIO 3), 12MB RAM

• Have installed a 486SocketBlaster with an Amd 486-100, which runs as a 5x86 133Mhz

• ESS 6886 Sound (Sound Blaster Pro clone)

• Internal VGA monitor. No external connector.

• Cirrus Logic VLB CL-GD5424 512 KB Graphics 

• 2 GB SD Card (PC has 8,4GB Limitation). But only 512MB is seen from DOS/FDISK. 

  • SD card is accessible on the front.

  • Maybe installing XT-IDE BIOS on the NIC could give me larger disk?

• Internal coin battery took no charge, so I replaced it with a CR2032

  • J11 Replacement Battery Connector, does not work - i measured.

• I removed the Modem card from the machine.

• If boots with garbled screen, try removing the MB drawer and insert again.

• Cirrus Logic 7543 Viking (1MB) Video adapter

  • Composite Out is set in BIOS to disable/PAL/NTSC. Tested and works

• The "5" key can not be pressed. But it pressed it selves from time to time. - annoying.  Have tried to clean the key without opening the machine.  Fixed by remapping "5" to "nothing" by using Ansi.sys  / nansi.sys (Freedos 1.2) and this in my autoexec.bat:

  • PROMPT $e[96;"5"p$e["5";0;79p$p$g

This remapps the "5" key to END, and the remapps " ' " to "5". So now when the 5 keys sticks it only sends an END og line command. This remapping only works in DOS.

• Hinges broke 13.03.2025, fixed by using Expoxy on the left hinge and Superglue/Baking powder of the right hinge. Lets see if this lasts. It looks good so far.

  • AIDA report Sound Blaster Pro (DSP 3.01) 220H, IRQ 5 and DMA 1, NeoMagic NM2200, AdLib and Windows Sound System (530h). NSSI report MIDI port on 330h. Address, IRQ and DMA can be changed in BIOS

• Have changed the CMOS battery. CR1220 - under a lid at the bottom. 

• After upgrading BIOS.The SAVE2DSK.BIN  hibernation file did no longer work. I fixed this by creating a partition that was slightly larger then i had RAM. In my case i reduced the size (Partition Magic 6.0) of my partition so that i had 175MB free. When i then started PHDISK /C /P it created a partition in the empty space and formated it. After this the RED warning at boot, was gone.

1. Considering a larger harddrive (CF, SD or IDE to MSata)

• Pentium II 400MHz, 228MB RAM, 8.0 GB HDD

  • Norton SI reports this machine at 985 x relative speed to IBM PC

• Windows 98 SE

  • SVGA (1024x768)  in 24bit.

  • Plays 320x200 games in full-screen - as mentioned this is a good DOS gaming machine

1. Considering a larger harddrive (CF, SD or IDE to MSata)

• Pentium MMX 300 MHz, 32MB RAM, 8GB CF - superfast

  • Norton SI report this machine at 1019 x relative to IBM PC

• MS-DOS 6.22 - 4DOS 4.02 - no Windows because is used Compact Flash as Harddrive.

• NeoMagic NM2160 MagicGraph 128XD - 2MB

  • 800x600

  • 320x200 scales to full screen

• One USB port - working from DOS with DOSUSB

• Yamaha OPL3-SAx - very good SB compatibility and real OPL3 chip

• CD-ROM and 1.44MB Floppy

• No fan noise

• Very good DOS Gaming PC, full-screen gaming and full Adlib/SB Pro support.

  • NTSC/PAL composite output

• Audio - YMF744B-R (DS-1S)

  • Windows Sound System

  • Sound Blaster Pro compatible dos DOS games in Windows - not good

    • DOS Games is not important for a Pentium 3.

  • Try VxD / WDM drivers...

  • I tried with SBEMU from DOS - did not work.

  • Using Yamaha YMF744 driver for DOS works ok. Have to use IRQ 11 for SBPro - not all games support that IRQ. Doom and Doom2 works fine, even it fails setup.exe. Supaplex crashes PC when playing effects.

• IR, COM1, LPT, USB, V.90/K56flex™ modem

• DVD Player and DVD Software.

• Trackball is faulty only moves up and down. External PS2 mouse works fine.

• More specs. 

• The two drives to the left are not working. Propably the drive belt.

• The bottom right is tested on Toshiba T2150CDS and works - but makes noise.

• The top right is Fujitsu and is belivede to be working. 

• Have drivers to the Xircom - installed in both IBM Thinkpads

• NSTL Combo card is installed on IBM TP 600E

• Pentium II - 350 MHz,  384 MB RAM, 128 GB SSD (8+120 partition)

• Windows 98SE

• Sound Blaster Audigy 2 zs - SB0350. 

  • Because we are using this PCI card this is not a good machine for playing old games. The DOS compability is poor. And that is ok, this machine is buildt for Windows 9x gaming.

• Voodoo3 -2000 - 16MB  AGP - only graphics card.

• 3,5" 1.44MB Floppy

• DVD and a a Sound Blaster Audigy breakout box/bay.

• Have replaced the Case back fan with a new and silent fan. PSU fan is still hearable.

• YouTube video

• Links: MPXPlay (Audio Player dos DOS) and Audigy12 - Patch for Audigy 2 cards using DOS drivers of Audigy 1  

• Note: The Audigy 2 zs WDM drivers for windows made the machine run slow and the Win9x games was unstable, and sound was laggy. But the DOS support was ok. With the VXD drivers windows games was much better, no lag, and Windows performed better. But no SB support in DOS. Uses DOS Drivers for Audigy 1 with patch to get support in Real DOS. - Works ok, but not perfect. Remember for Tick the MT32 box in SBEmixer.exe for Roland compatibility . Vogons.org has more. I am using the 8 MB Wavetable.

• Note 2: Sometime midi does not work in DOS. Then it helps to start Doom2 to initialise the sound card. Also in some games like Tyran2K digitized sound does not work. I guess that the Audigy is not 100% compatible with SB Pro/16. 

• Note 3: Maybe Unisound fix fix the above problem?

• Note 4: Another way to install Audigy drivers for better DOS compatability. 

• Note 5: Maybe SBEMU -works better. Check out github for SBEMU

I miss the sound of the older hard drives.

I miss the sound of a dot matrix printer

I miss the sound of dial up.

I miss the sound of the modem handshake.

I miss the Turbo button.

I miss the sound of a floppy disk read/write.

I miss the days of the BBS.

I miss the ANSI graphics loading at 2400 baud.

I miss the excitement of opening a new game in a big box, only to have a few floppy disks or a CD in the box.

I miss drooling over the specs of the systems in those advertisements.

These are what I miss :(
