[wellylug] Flash RAM/EPROM disks

In order to use some old computers as dedicated boxes running embedded 
linux code, I want to replace some boot devices (floppies or IDE HDDs) with 
solid state disks (Cost is a significant consideration and USB is not an 
available option).

For some things I only need 1.5MB of storage so was thinking of building an 
eeprom floppy drive replacement/emulator device.
Anyone seen a circuit for one of these (there are a few notes on the web 
suggesting there was a Steve Carcia Circuit Cellar project years ago).

For larger systems some sort of flash ram card (32MB?) would seem to 
suit.  I see there are 'flash ram cards' and 'compact flash ram cards'), 
does anyone know whether either of these have the same connectors as laptop 
HDD drives? (pictures of adaptors to plug them into IDE appear to have no 
active components but just small to large plugs - can anyone confirm?).

Anyone got a cheap source of such devices?

Tony.
