2 x Iomega Zip 100 - 1994
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
Iomega Zip 100 - USB
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. E.x. 84 MB in 7 minutes.
USR Sportster 28.800 modem - 1994?
In original box
Yes - it is standing on a gold plate.
Why? Because it gives my good feeling. Just like the guy on the box cover.

Sound Blaster, and Sound Blaster Pro compatible (3.01)
Interrupt, DMA and base address can be changes with esscfg.exe
Also AdLib and Windows Sound System (604h) compatible. Some apps sees an SB16, but this only works for FM sound. AIDA 2.12 sees a SB16 with high DMA 0 - but when testet is does not work.
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:
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.
IBM Thinkpad 390 - 1998
Pentium II Mobile 233Mhz, 160MB RAM, 3.2 GB HDD
Norton SI reports this machine at 584 x relative speed to IBM PC

3,5" Floppy / CD-ROM / PC-CARD (type 3) / PS2 Mouse / IrDA / USB / LPT1 / RS232 / VGA
Neomagic NMA2 Audio controller - ISA 16bit
I believe that is has a OPL3-SAx (YMF719)
No need for drivers in DOS. A good DOS gaming machine.
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
NeoMagic MagicMedia 256AV (NM2200) - 2.5 MB VRAM
SVGA (800x600) in 24bit.
Has D-Link G650+. But sadly this card does not support WPA2 in Windows 98SE
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.
Considering a larger harddrive (CF, SD or IDE to MSata)
IBM Thinkpad 600e - 1998
Pentium II 400Mhz, 228MB RAM, 8.0 GB HDD

Plays 320x200 games in full-screen - as mentioned this is a good DOS gaming machine
Considering a larger harddrive (CF, SD or IDE to MSata)
IBM Thinkpad I Series Type 2611 - 1999
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.

No fan noise
Very good DOS Gaming PC, full-screen gaming and full Adlib/SB Pro support.
Have drivers to the Xircom - installed in both IBM Thinkpads
NSTL Combo card is installed on IBM TP 600E
Dell XPS - 1997 - 1998 (est.)
Pentium II - 350 Mhz, 8 GB CF Card, 384 MB RAM
Sound Blaster Audigy 2 zs - SB0350.
Voodoo3 -2000 - 16MB AGP
3,5" 1.44MB Floppy
CDR and DVD
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.

SD2IEC - SD Card for Vic 20, C64, C128 and C16
Works on most programs, games and demos. But new demos/games tend not to work.
Running version 0.10.3-M1284P-LARSP (date: 2012-02-26) not possible to upgrade - i think.
Works well with my Final Cartridge III
Does not work well with 128D because the 128D har built-in Floppy drive in ID 8
Is works fine with a special version of GEOS for C64.
