Word to the wise for anyone who picked up a turbo driver:
The turbo driver won't fit if you socket the 6502!

No, it's if you socket mount the 6502 on the turbo driver. It's all rather tight. I just ended up soldering it direct to the board (and even then I had to snip the tops of the header pins beneath it flush with the pcb to get it to sit nicely). Works perfectly though, the PAL gets a little warm...

I'll nab some header pins off you though, always useful. See PM :)

Hmm... Don't think so unless this old willem I have won't deal with them. I have my eyes on a VP290 as soon as I scrape the readies together. I haven't noticed anyone saying they've decoded it?I can't imagine it's that complicated.

AllanD decoded them a couple of years ago, a some of them where flakey, I'll dig the equations out tomorrow and post them.

The Wellon doesn't support PLDs either! GAL are supported, however. I have a VP-880 (went obsolete two weeks after I bought it ](*,) ) and was most disappointed, they won't even READ PLDs. You wouldn't have thought it would be that difficult? I suppose they have to draw a line somewhere!

ARgh. chip-programming-minefield. In the realms of my tinkering would I ever find myself in a situation where I'd need to use a PAL rather than a GAL? There are a whole set of GALs that are just drop-ins for the early PALs aren't there?

Just depends how many you found in the loft :oops: And, how many you used as 'masters' for your firmware :oops:

Thanks Alan, I'll try and gal-i-fy this and see if my turbo driver diminishes in toastiness!

Also good to know this as I'm not sure if all the turbo driver boards that Arcadian shipped had the PAL in already and they're pretty much useless without it.

I have just ordered 10 GAL 16V8B Atmel chips which I will program if anyone wishes to change their PAL's for a GAL or is just missing the chip.

Cheers for uploading the code Alan.

Right, got back home from GEEK in the early hours, so I'll finally be able to get the 3-4 packages sent that have been outstanding since last week.

Thanks for posting your Turbo source for the PAL, Alan! :)

Cheers Dave, got my turbo driver today..

Havent been able to get it working yet though lol....

Elk acts as if no 6502 is inserted but all continuity tests to the mobo and turbo board are fine..
Have replaced the 6264 and CPU to no avail...

The PAL does warm up nicely as expected....

Will persevere with it though...

Cheers.

That's really odd :? Mine's working fine - there's almost nothing to go wrong with them. PAL fried?

That is possible, when I got mine a couple of years back I had to use Alan's reverse engineered PAL code to program a new PAL/GAL (ATF16V8B IIRC).

Cheers Phill,
It's the only device left on the board not replaced.

I have some Gal's arriving soon, hope my G540 programmer can manage them as it does list the devices...

@danielj I fitted somewhere around 20 of these to ELKS for Arcadian (Dave) a couple of years ago i'm guessing these boards are out of the same box (correct me if i'm wrong Dave). At that time some boards had no PAL fitted and of those that did a significant number did not work .My guess was that some of the PALS where either programmed incorrectly or just blank. Phil HS also experienced same PAL issues i think.

P.S.

if you suspect your PAL has failed and you remove it you can test the rest of the board by temporarily linking the following pins in place of the PAL this will make your turbo board run in normal mode but it proves the 6502 is ok and the ELK motherboard is OK

feed thru A14,A15 and ROM enable
Pin 1 = romoein; to Pin 19 = romoeout;
Pin 2 = upa15; to Pin 16 = ulaa15;
pin 3 = upa14; to Pin 17 = ulaa14;

Remove RAM Chip or Disable with following two links
Pin 14 = ramnoe; to PIN 20 VCC
Pin 18 = ramce2; to PIN 20 VCC

Hi Alan, thank you very much for your kind input..

I have downloaded your pld file and should be recieving the gal's in the next few days..

I have a Genius G540 programmer which claims to be able to program the devices but I am somewhat confused regarding the file type I should load your pld file into the buffer.
Selcting bin file does show up your ascii (c) messages in the buffer..

Any help or guidance would be appreciated as if I am successful I would be happy to send replacement chips out to anyone who needs one.

Cheers.

You need to compile it with wincupl (free download from ATMEL) into a jedec (.jed) file. That can then be written into the GAL :)
