Upgraded Dragon32 ram test software

Post by drygol » Mon Sep 02, 2019 10:08 am

Hi everyone,

I've just made a RAM upgrade of a D32 to 64k described here: http://archive.worldofdragon.org/index. ... 4K_Upgrade

Now, I am wondering if there any convenient ways to test this upper half of RAM. I only have CoCo SDC and so far I had no luck finding a working RAM test on a VDK image.
Shall I just rewrite listings from the above-mentioned article to test it?
Does anyone have these BAS listings somewhere?

Cheers

Hello,
probably a good way to test if the 64k upgrade works well will be running some games that 'need' 64k RAM to work
For instance this AGD game I converted some time ago: Foggy's Quest that you'll find here
viewtopic.php?f=7&t=5723&p=16891&hilit= ... est#p16891

If this works flawlessly on your machine (I hope so!), then you will be able to play some 201 games that we have ported from
the ZX-Spectrum AGD to our Dragon/CoCo machines.
You could search for AGD converted games in the Uploads section and will find quite a lot, but best option will be going for the
BIGPACKs v2.4 I uploaded lately. These zips contain all of the games in VDK format so that you could copy them into your CoCoSDC
I think that it is best to use on the SDC the ones with short name

enjoy!

Duh! triple facepalm :oops: :oops: :oops:

Why oh why, I was looking for RAM tester when there are so obvious ways to test it lololol.

I've just successfully run Foggy's Quest! looks like my 64k mod is working!
Thank you again, sir!!!

I will cover the whole story on my blog - retrohax.net

You'd get music on the title screen of Dunjunz too (plug, plug!)

Great story!

I think it’s nice how you managed to use the Amiga PSU, as one of my trusty Dragon PSUs gave its best after more than 30 years of service.

Thanks a lot!
