Ärende: message seed
====================
On or about 01-04-10 07:06, TOM WALKER allegedly uttered "message seed" to ALAN
ZISMAN:

 AZ> TW> And those Old AT machines do not use IDE drives do they??

 TW> ypou just triggered soem Brain Cells. Those onf Drives wree ISA but the

RLL/MFM: Run Length Limited/Much Further (away than my) Memory. <G> IDE stands
for Intelligent Drive Electronics, and AFAIK only came on HDs. Industry
Standard Architecture (ISA) is the now defunct expansion bus on MBs. Todays
floppies still use RLL or MFM, but the edge connectors went out of favor a long
time ago. Separate data and control <?> cables is one for the museum!

Shoot... Now that I understand better - sorry I missed the "AT" part on my
first read - why not use a newer machine with a multi-pin (There's a name for
it, that is not coming to mind.) floppy cable and BIOS support for both sizes,
and use that to read the 5.25" disks? 5.25" drives used to come with that pin
format, plus a single edge connector. They might be a little rare, but
attainable. The trick might be to find one without cooked head gaps. From
there, USB stowage becomes more feasible.

I think DOS 4 came with SLIP/PLIP tools; is the only other way than NICn' two
machines that I can think of right now.

 TW> I do stil have an Old Adapted Full Length Card HD controller. But I

 TW> cable better.

There are (14-pin?) adapters for edge connectors to that modular format, but I
do think the BIOS needs to support 3.5" floppies for that to be workable.

 TW> Looks like I am going to have to go up and get the computer and broinhg

 TW> Her son has been trying to talk her into getting a laptop so I wil

Any way you slice that tomato, you'll be in for a long day. Good luck with it!
