ICE T65/Z80/6809

[zippysticks]

I got my adapter PCB back today -- supports the GODIL with female headers, and has configuration jumpers on the side (at expense of a little extra width):

Hey - that looks brilliant and exactly what I need for the GODIL I bought.

Do you have any spare you can sell me please ?

I finally got my level shifter board from the shop (due to me being distracted on other things, not due to any issue around stock levels) after I rebooted the thread 9 months ago due to lack of GODIL's. So far so good. But do you think I can remember where I put the Spartan FPGA !!?? (Perhaps it is in the same place as Dave's missing stuff from Wakefield).

So now that I have my FX2 Cart this is clearly much easier to use that the ICE-T but the ICE-T has other feature that can be useful. Also the other thing about ICE-T is easier to use on non Acorn hardware.

I am thinking along the lines of using it for my SWTPC, which is 6800 based rather than 6809 (like later ones). I ahve a couple of thoughts around this:

1. 6800 support added to ICE-T; or
2. A home brew 6809 adaptor board for 6800 machines
http://www.vcfed.org/forum/showthread.p ... ter-needed
3. Or both

(2) Is looking maybe best as I dont think there is enough clearance in the SWTPC to get the ICE-T in. I maybe able to rearrange the boards to fit it. If I did (2) I could have the daughter board, that the ICE-T would be plug in, on a short cable to clear it from the cards. Not sure how long you can get away with.

Thoughts, comments?

I am currently still cataloging everything for the SWTPC and I will put it up somewhere at some point.

Finally tested in a L-STAR and all working. Definely easier than doing a manual decode with a 16 channel logica analyser, which is what i was doing before (which was a year before Hoglet's 6502 decoder FX2 software).

Great it's working for you.

For anyone else who's interested:

There are still a couple of level shifter boards available (£12) in Jason's shop:

And the "eepizza" boards are still available ($31) on eBay:

Hello, new user here. I found this thread, and have an interest in the ICE, because I can use it on my other classic computers (sadly, I haven't any Acorn computers yet).
So I have already ordered a XC6SLX9 board from 'eepizza', and it should be on its way now.
But - it looks like Jason's level shifter is out of stock now.
Does anyone know of an alternative? Perhaps someone has published design files for such a board?

Hello Torfinn,

Welcome to Stardot!

But - it looks like Jason's level shifter is out of stock now.

Have you tried contacting Jason to see if he is planning to make any more up?

There are various contact details on the Xeropage website and he is a member here in the forum (flynnjs).

Jason usually orders a batch of 'whatever' when he gets enough interest. Have you tried dropping him a mail to ask if/when he will build some more? He must have only just run out. I am not sure if his level shifter are open source, although the smd component would be a pain to solder.

I am guessing you came via Vcfed.org.

Edit: Ah Hoglet posted while I was replying.

So I have been playing with ice-t on Beeb with video issue, and though it could be useful if you could dump an entire program into memory. I don’t think you can do that other than a lot of W commands.

My idea was you could write a program on an emulator. Dump the memory to a file with something like *save

Then run a command on icet like import <start mem location>, and then push a text file from the term program. Then finish with an ‘finish’ command, assume import file is all bin so get push straight in.

You could then blind type run on the computer. Or maybe use icet to fudge program counter or something.

If I remember correctly, there is already an S-Record loader:

Ah that would be useful. Is it missing from the wiki manual? I can’t see anything about s-record or ‘srec’

Ah yes, I think the manual pre-dates it. Easily fixed.

[Elminster]

Well that has to be fastest feature request completion ever then

Might have guessed my idea had already been invented.

Thanks.

Then I just have to workout how to read the right bit of memory back and convert to something meaningful after the program runs, migh5 be hard. Might try a bit more with logic probes, multi meter and scope on my issue first.
