The Evotek drive initially used the notoriously unreliable Ampex Alar plated media; whether they ever upgraded to sputtered media is uncertain. It probably should be avoided.
I would look for an replacement drive using oxide media. The nice thing about oxide media is it came pre-corroded so that's one thing not to worry about in a 35 year old drive Tom -----Original Message----- From: Chuck Guzis [mailto:ccl...@sydex.com] Sent: Saturday, December 05, 2015 11:13 AM To: General Discussion: On-Topic and Off-Topic Posts Subject: Re: Evotek Winchester Harddisk On 12/05/2015 10:36 AM, Oliver Lehmann wrote: > Hi, > > has anyone ever heard of Evotek ET-5800 series Winchester harddisks? > I wonder which interface they have.

OEM manual is on Manx: http://manx.classiccmp.org/mirror/harte/Evotek/ET-5000%20Family%20OEM%20Manual.pdf Back in 1983 I had an opportunity to play with one. Pretty interesting, but very expensive, as I recall--and not terribly reliable. --Chuck
