Looking for a few things`

[lutiana]

I am looking for:

1. 8087 Math Co-Processor for an IBM 5160
2. NEC replacement for the 8088 proc for the 5160
3. Someone to burn the latest BIOS onto some chips for the 5160, and a custom BIOS I found.
4. 3.5" floppy adapter (the one that allows you to convert the slot connector to a pin connector) No need, as I have gotten number 6 to work
5. 5 1/4" disc holder(s) Got it
6. 8 Bit FDC controller that allows 1.2mb and 1.44mb floppies to be used in the 5160 Got it

I can trade 360k floppy discs, and I have some more contemporary hardware but not much true vintage stuff.

PM me with a price or item trade if you can help me out.

Thanks in advance

For hooking up a 3.5" 1.44 meg floppy, consider this alternative:

First get a 16-bit multi I/O controller like this:

http://lh4.ggpht.com/_CzHY0sEvu6A/SPjY43aEc0I/AAAAAAAABCM/JkuROfJwjB0/s800/IMG_1579.JPG

The get this software:

ftp://ftp.simtel.net/pub/simtelnet/msdos/diskutil/2m30.zip

and add the 2M-XBIOS.EXE to your config.sys file

If you need help configuring it, read this thread:

Neat trick; never thought to do that. I wonder what else will work (ie. will the serial and parallel-port extensions to some of these multi-format cards work too?). Something to try on a future clone.

I believe the adapter pictured at http://store.microconnectors.com/catalog/F02-223.jpg would be a whole lot easier and more cost affective.

I believe you're responding to item (4) where AC is responding to item (6).

Yeah, I was responding to #6. But If you use a new floppy controller as shown, then you can use a modern cable too making the converter piece requested in #4 unnecessary.

Parallel and serial ports work just fine too. I've had one of these multi I/O cards since day one, and it really helps with the transfer rates using laplink on the parallel port too.

Check. Mine is the exact same chipset, just without the serial and parallel ports, and I disabled the IDE section of it.

Check.

It works flawlessly, I am able to format and read 1.2Mb disks, I will try it with a 1.44mb drive as soon as I get a power adapter (or make one).

One issue i can see with this is booting, specifically if you pull the original FDC and use this trick as your main floppy controller.

Did you leave your original IBM floppy and floppy drive in the system?

I currently use one that doesn't require drivers at all. However, since it lacks a BIOS extension, I can't use 1.44Mb disks with it.

However, it does read and write fine to 720Kb disks. But somehow, it can't format them.

I use a new-old-stock-slightly-modified 200W AT clone-PSU in my system. It provides the proper power-connectors for 3.5" drives, so I don't need adapters.

About the NEC V20 replacement CPU, see here: http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?jameco_page=42&langId=-1&productId=34358&catalogId=10001&freeText=UPD70108&storeId=10001&search_type=all&ddkey=http:StoreCatalogDrillDownView

An 8087 might be a little more tricky. There are usually some for sale on Ebay, but not right now (at least not in the rigth price range).
