DDRUM 4 to SE 1.5 Upgrade Eprom File

[notaufnahme]

Hi, Iam new to this forum.

I bought a DDRUM 4 with version 1.32. Now I wanted upgraded it to version 1.5 SE.

I friend of mine do have an EPROM burner. Does anyone of you has got the .bin/.hex file of the 1.5 version and could send it to me via PN?

I couldn't find it.

Thanks Frank

Greeting Frank!

I have never stumbled across anyone who has the actual bin file to share but there are chips available on Ebay & Reverb that I suppose you have already discovered.

Cheers!

Hi.

Here are ddrum4 eprom images. See rel notes below.
Important! Check the Flash chip (8 of those) type on your dd4 hardware!

Best,
Deve.

Hi All!

With Deve (developer ) being so kind as to provide the bin files I thought it would be fun to do a burn test so I purchased a GQ-4x4 from MCUmall and some AMD27C040 chips. Reading an existing 1.5 eprom and comparing to the 1.5 bin file from Deve showed them to be the same so I burned to a new eprom, installed into my 1998 dd4 (originally 1.32), held my breath, and powered up. Success!!



Cheers!

Hi again Ken,sorry to bother you again but I have a 1.33 ddrum4 which I am trying to up to 1.50,I bought the chip but haven't gotten it yet,it's been 8 days from Italy,but I just read your eprom history and I have an AMD 1.40 version 1990 chip and a 1.50 singapore 0324K chip so is it possible to try either of these without fear,sorry for all the posts,I'll delete the other one,thanks Ken

The 1.50 would be the best between those two with respect to features. Are they originals from another working module? As long as they are intended for the dd4 they should be safe. Make sure to never attempt an upgrade from 1.50 or less to 1.54 as each is targeted for a different chip set.

Cheers!
