yes i have... thanks

didnt much fancy forking out £20 for them though to be honest. I'd be happy with some home made/2nd hand ones.

if you mean some eeproms, they will not be much cheaper and they can also loose content in shorter timeframe than originals. just my 2c

I want KS 3.1 too.
However i am about to try BlizKick to map a 3.1 image into my Blizzard 1230MK II. Has anyone had success doing this?

My UV KS3.1 EPROM for my A600 is 12 years old and still going.

If Blizkick supports your hardware then it is easy. But AFAIR your MMU is not available following a BlizKick.

anyone?

The typical data retention time for ST's EPROM memories is 20 years ie. .)
alexh have 8 years left

No-one is going to sell you KS EPROM's for less than £15. Just not worth getting the EPROM programmer out for less.

£17.61 from AmigaKit
£15.92 from Vesalia in Germany, but with postage it will be the same as AmigaKit.

DoogUK · 19 January 2009, 18:36

even on ebay they go around the same price with postage.

Indeed, the chips alone generally cost about £5 each (ish)

Unless u know a cheaper supplier alexh *hint hint* lol

alexh · 19 January 2009, 19:32

£14.10 from Analogic (high postage costs though)

If you have a EPROM programmer that takes 27C200, 27C400 and 27C800 chips then gimme a PM.

27C800's (which are 4x larger than needed) are actually cheaper than 27C400's! (Make a simple KS Switcher!)

Remember to get chips with a speed grade of 120ns or better.

As far as I can tell, 27C200s only existed as Mask ROMs.

If they were Mask ROMs then they wouldn't be called 27C200's would they?

If you mean that there is no such thing as a 27C200 then maybe... Almost sure there is.
