Based on several articles about this matter , it seems that you can not burn a GAL with a PAL jed files .

Can anyone convert this file with PaltoGal ??

i can not get paltogal working on my 64 bit win 11 pc ..................

i tried this file on a GAL16v8 and the ql does not start .
Original is a PAL16l8anc

A lot of these older executable won't run on Windows 11 directly - but, depending on the version of Windows 11 you are running, you could run Hyper-V and that allows you to run a much older version of DOS in a virtual machine, doing this will allow you to run all the opal junior suite for instance, making GAL programming possible.

The other alternative method is to source a copy of WINCUPL, and this allows you to write GAL code directly

Prof ,


I would need a full "how-to-do" to get that running .

I'm fairly certain I used DOSBOX to do this last time. I seem to remember something special with the filenames too

So if you are going from 'scratch' and creating your own logic - then this will help:

WinCUPL -this does run under Windows 11

In terms of running Hyper-V under Windows 11 - this depends on your version - you will find it under features - but I suggest you read up on this if you've never used it before

A link to Hyper-V installation: https://youtu.be/WnV5zxgva5Y?si=pVgaGQ04xfNO1Abq

Once you have a VM created - find and install a copy of DOS on the VM - then copy your tools to it.

A dosbox won't work with these older executables - they are several generations behind, sadly

I have created a working 2v2 on a GAL before, using the PALTOGAL utility. I also needed to try several different speed GALs. What I did find is that with an original PAL either as the 1v4 or the 2v2 I could add one gal, but not both ?? Tetroid does explain a PAL is required as the timing is quite critical on a post somewhere on here.

I suspect the RAS / CAS and address mux signals rely on propogation delays and logic timing - it may be possible to chose a GAL with a slower speed to come closer to the PAL design specs. Having the equations would help - as it should be possible to see what is being done.

thanks for answering !!

@pr0f ,

do you have the jed file you used ??

Hi,

I use pal2gal, palasm, wincpul in virtualbox, which runs in a MSDOS Virtual Machine, this seems to be the best way to run old software.
