Hello everyone,


This is a pic from an AT that recently sold on eBay. I thought IBM did not offer an internal 3.5" drive option for the AT but this drive looks to be an IBM model/part (maybe it for another system line). Anyone know the brand/model number? Thanks.

EDIT: I think it is an Alps 413 (found in PS/2s) but not sure about the bezel...

IBM marketed an add on 720K 3.5 inch drive ... I have one of these with a black faceplate
and the drive itself is a Toshiba.

mikey99,

Yes, I have one of the black ones as well in my IBM 7532 Industrial AT system. I am not sure however as to the model/brand of the actual drive. However, the auction listing was the first time I saw the beige model which seems to be a better match for the "standard" Alps drives used in the 5170. Thanks for the pics.
 
I think the drive I have was an 'option' for the 5160 XT. I purchased this drive new
back around 1988.... and used it in an external enclosure as a second drive for my PCjr.
 
I have Toshiba ND-352TH-A in my XT 5162 and 5160 machines as pic, Also have a 3.5" in my 5170 with beige face plate, can't remember the model though.

The IBM model numbers for 3.5" drives are:
3258 3.5" internal half height for XT
4865-001 External for PC/XT/Portable
4865-002 External for AT (720kB)
0357 Internal for AT (720kB)

Hi,

I know about the 4865-00? parts (we discussed them in this thread). However, the other two are new to me. Where did you get those part numbers? Are they from official IBM price lists or manuals? That would be interesting as I had always thought the only 3.5" kit was the external one requiring the EDA for the 5170 and 5162. I wonder if the black HH industrial (like the one mikey99 posted) is the 3258 kit?

TIA!

Malc,

I believe yours is an aftermarket upgrade - which was very common even straight from dealers.
