The title pretty much says it all. Would a 16bit ISA MFM\RLL + Floppy card be able to work in an 8bit slot? I'm thinking yes, but I don't know what the side effects would be... the 16bit portion has to do something. I'd only need one hard drive and two floppies accessible.
My reason for wanting to do this is related to a post in another thread... it got me rethinking the idea of putting my Soundblaster CT1350B (hopefully with CMS upgrade eventually) in my IBM 5150 with a 286 upgrade. I know it isn't a perfectly matched system, but I don't own a 386, so it currently serves as my system to play the oldest of DOS games (pre-VGA).
These systems are incredibly limited by having only 5 8bit ISA slots. The slots are currently populated as such:
Slot 5 - Everex EV-659 (EGA+Parallel)
Slot 4 - AST SixPakPlus (384k memory expansion, RTC+battery, 1xSerial, 1xGameport)
Slot 3 - Original IBM Floppy (Connected to 5 1/4 Tandon 360k and 3.5" TEAC for 720k support)
Slot 2 - Western Digital WD1002A-wx1 (MFM controller connected to 20MB Miniscribe drive)
Slot 1 - Orchid Tiny Turbo 286 (Switchable between 8088 4.7Mhz and AMD 7.16Mhz 286)
To add a sound card (or anything else) I'll have to remove something, but they're all integral to the computer at this point, so my only option is to consolidate two cards into one... hence an MFM\RLL+Floppy controller... but they seem to always be 16bit.
Now for some blitting from the back buffer.
