If you can put USD 50-100 in your antics, you may add an XT-IDE ISA card with a Compact Flash adapter. The one I have has a slot in the backside metal bracket: I can load a Compact Flash (1 GiB, FAT-32 formatted) in a modern PC with a USB adapter, then I insert the Compact Flash in the back of my IBM PC and switch it on with new fresh data and software. Note that the Compact Flash is seen by DOS (6.2 in my case) as a hard disk drive, you may boot on it. It may also co-exist with an MFM harddrive: in my case, the MFM drive is C: and boots, the Compact Flash is D:. It is a very convenient setup to make the IBM PC a smooth place in our modern IT world.
