Morley 16-bit Cached SCSI Podule

Post by simoni » Wed Dec 11, 2019 11:59 am

I am in the process of repairing a Morley SCSI card, the same one as the following link:

http://chrisacorns.computinghistory.org ... dSCSI.html

After some testing, I've discovered that the EPROM is completely blank... Does anyone have an image of the EPROM for this board so I can bring mine back to life? The chip should be a 27C512 (64Kbytes) EPROM.

Thanks!

Sorry, I thought I had one, but it turns out it was a cumana card.

Any luck with those EPROM images @Boydie?

Just to report back... a couple of replacement 74HC245s and a new EPROM... and it's back in business. The card is now fully functional again :)
