Please have a look at my posting from Thu, 23 Mar 2006, subject
"Re: ImageDisk / PC FDCs & single-density".
Arranged into your format, this would be:
Data rate
250 300 500
Manufacturer FDC chip SDX SDX SDX
-------------------------------------------
Acer M5105 PPP NPN PPN
Intel i82072 PPF NPF PPF
Intel i82077 FPF FPF FPF
Nat.Semi. DP8473 PPP NPN PPN
SMC Super I/O PPF NPF PPF
WD WD37C65 PPF NPF PPF
Winbond W83757 FPF FPF FPF
As these were mostly add-on ISA cards (what else ;-) there are no
mainboard manufacturers and models, and no CPU class; the same card worked
in different class PCs (testet with 80386SX-20, P5/60 and P5/100 systems).
Hi Christian,
Thanks for the information - I'm going to create a second listing in my file
for "incomplete" information - Often there are other factors in the design
in addition to the FDC chip which affect the capibilities of the system as a
whole, so I think it's worthwhile noting the actual board and model tested.
The reason I list the FDC chip however is because they are one of the most
important factors in determining floppy capabilities, and I wanted to give
people enough information to "comparison select" - (humm.. I don't have
any of these boards, but I have one with this FDC which seems to work on
several other boards - It might be a good candidate).
For IO cards, I plan to use a class of 'IO' - I'll list these as '?'
since it
appears to be a mix of I/O cards and mainboard FDCs - unless you can clairify
it further.
Regards,
Dave
