Target-Earth Blog!

Here's the TargetEarth blog, it's mostly useless information with a few extremely niche tech posts…

Some useful shortcuts:

  • Video Game database - current database of my gaming systems and games
  • Tech stuff - network installers for Unix-like systems, old hardware, retro gaming etc.

Adding Modern Storage to Retro Computers

Old computers are cool, but hundreds and hundreds of cassette tapes, floppy discs, cartridges and cd-roms is most definitely not. They also take up a huge amount of room.

Most of my retro systems have at least one type of more modern mass-storage device, some more useable than others.

Acorn RiscPC 700

The RiscPC has standard IDE headers and can use industry standard IDE hard drives, Compact Flash adaptors and optical drives.

Currently fitted: Internal IDE to Compact Flash adapter + 8GB CF card.

Acorn A7000

As per RiscPC, the A7000 has standard IDE.

Currently fitted: Internal IDE to Compact Flash adapter + 8GB CF card.

Amiga 500

No mass-storage provision as standard.

Amiga 1200

On board 44pin 2.5“ IDE header was fitted as standard.

Currently fitted: 3.5” drive bay with Compact Flash reader to IDE. SCSI CD reader attached to Blizzard SCSI IV.

Amstrad CPC

No mass storage as standard

Apple Macintosh IICi

Came with SCSI 1 onboard controller.

Currently fitted: Aztec CF Monster, SCSI to IDE/CF bridge card and Compact Flash card.

Modern Keyboards & Mice for old computers

I have lots of old computers… ZX Spectrum, Atari, Amiga, BBC, MSX and more. One of the problems I have with them all is getting enough desk space to use them. Not a problem with old consoles; they can typically be put on a shelf with power and video and they'll just work, of course with a computer you generally need enough space to have the keyboard in front of your.

To show the complexity of just how much stuff I have to fit together, here's a diagram I had to make when mapping out the connectivity…

There's just no way I can afford to have 10 or more keyboards on the desk, so they have to be put on shelves out of the way.

This is a problem you need to solve when you are being kicked out of your man cave in order to make room for children.

So, one option is to add a remote keyboard, either PS/2 or USB, and switch them all through a KVM switch or similar. Fortunately most systems seem to have something like that available.

DOS / Windows PXE booting

I don't often need to do this, but once in a while it's handy to boot to a MSDOS boot floppy (either 6.22 or 7.00) from a machine that has PXE support.

Here's the pxelinux.cfg menu entry that will boot either a DOS or Win 98 SE boot floppy image:

default syslinux/menu.c32
prompt 0

MENU TITLE MS-DOS/Windows Installer Menu
menu separator

LABEL DOS - MS-DOS 6.22 Setup Floppy i386/amd64
KERNEL syslinux/memdisk
APPEND initrd=dos/MS-DOS_6.22_Disk_1_Setup.IMA
Boot MS-DOS from DOS 6.22 setup floppy image. NO FAT32 large disk support.

LABEL DOS - MS-Windows 98 SE Floppy i386/amd64
KERNEL syslinux/memdisk
APPEND initrd=dos/Windows98_SE.img
Boot MS-DOS from a Windows 98 SE floppy image. With FAT32 support for large disks.

LABEL Return
MENU LABEL ^Return to Main Menu
KERNEL menu.c32
APPEND pxelinux.cfg/default

You need the following files:

  • memdisk - Part of the syslinux distribution (find it inside /usr/lib/syslinux/)
  • menu.c32 - Part of the syslinux distribution
  • MS-DOS_6.22_Disk_1_Setup.IMA - MSDOS 6.22 boot floppy,
  • Windows98_SE.img - Win98SE boot floppy (DOS mode), sourced from

This can be quite a handy setup for systems without a floppy drive, or those that need to boot to a DOS prompt in order to flash a BIOS or similar.
