Fitting slogger turbo driver

[Slo]

I'm in worksop notts kenlowe cheers i'll paypal you some readies sending you a pm

EDIT ~
I've just discovered that my monitor cable is faulty as the screen went blue and flickered when jiggling it about, i've just swapped it for another cable and the screen is rock solid again bloody mysterious coincidence that is but it seems to be fine now other than having built in central heating

[danielj]

That's the right file, yes!

[daveejhitchins]

Yes, AlanD's file is the correct one . . . If you haven't already removed your 6502 (?) I'd recommend a Low Profile 40 pin turned pin socket. You only gain 1mm but it ensures the board and components don't clash with the keyboard. I stock them just for this purpose - If you want one they're cost plus Postage.

Sent a couple of GAL16V8s to @slo, but they're not working correctly for some reason. The first time, I just took the jed file from the other thread and flashed it directly onto the GAL. The second time, I took the equation files and ran them through eqn2jed.exe to create the jed file, then flashed that onto the GAL. This is the equation file I'm using:

chip Slogger GAL16V8

romoein=1 upa15=2 upa14=3 upa13=4 turbo=5 phiout=6 upRnW=7 ipirq=8 
upnmi=9 GND=10 upphiin=11 uprdy=12 ramp1=13 ramnoe=14 ramnwe=15 
ulaa15=16 ulaa14=17 ramce2=18 romoeout=19 VCC=20 

equations

romoeout = /upa15 * /upa14 * /upa13 * /turbo
    + romoein

ramce2 = /upa15 * /upa14 * /upa13 * /turbo

ulaa14 = /upa15 * /upa14 * /upa13 * /turbo
    + upa14

ulaa15 = /upa15 * /upa14 * /upa13 * /turbo
    + upa15

ramnwe = upRnW

ramnoe = turbo
    + upa13
    + upa14
    + upa15

ramp1 = uprdy
    + phiout
    + ipirq
    + upnmi
    + upphiin

Can anyone see what I'm doing wrong? Do I need to invert the outputs by any chance?

[Slo]

As Ken says he's sent me 2 GAL's twice...

The FIRST pair, when the switch is in the turbo position with the PAL in, with the GAL in the machine just runs as if the turbo wasn't even there.
When the switch is in the normal position with the PAL in, with the GAL in the machine just hangs ctrl+break does nothing.

The SECOND pair is pretty much the same except if I just touch the power jack in the socket so I can insert and remove it quickly in the normal position With the PAL in but with the GAL in I can sometimes get the machine to boot to a prompt albeit with crap all over the screen, then I can quickly boot a disk with the test program on it before the machine hangs, then as before ctrl+break does nothing. The test program is reporting that it is at least working in turbo mode with a result of 16/17/18.

[Slo]

Still getting no joy with this, i've bought myself a tl866a programmer now and even a tl866II plus as well and still same results

With the switch in the turbo position (with the pal in) the elk works as normal with the gal in, switched the other way the machine hangs.

So it can only be one of three things, either....

1. Both Ken and me are doing it wrong which I don't see how, Ken for sure

2. It's an elk issue as this is an issue 4 machine (pal works fine), i've got another to try out though, no idea what issue yet

3. That .JED file is wrong, however i've tried messing around with the .PLD file in wincupl and compiled various times and none work, with the gal unencrypted you can see (in the programmer software) that the stored code matches the lines in the jed file and we've both tried encrypted and unencrypted.

Monday i'm posting my pal chip to Ken as he might be able to read it and compare results, in the meantime I will dig out my other elk and fit my other turbo board so I can try a gal in that one.

Are there any more members that have fitted a gal instead? Got to be more than 3 or 4 of us surely?

[Elminster]

Hmmm. I had two slogger turbo’s in two electrons. Don’t remember changing anything though, but I pulled both those boards and fitted Prime’s improved MRB instead.

Never had any issues with the turbo boards that I remember, in a box somewhere.

Edit: Although one of my Electron’s play up after I warms up and the video output how mad, but suspect for that is ula or video rather than MRB.

[KenLowe]

I'm clean out of ideas. Once I get the PAL I'll do the same as I did with my IntegraB PALs. I'll wire it up as an EPROM, read the EPROM, decode the data, generate the equations and compare with what was posted earlier. I'm hoping it will be different!

[daveejhitchins]

Ken . . .

I could test the Turbo board out for you? At least then you'd know if it was the board or your Elk playing-up! I have a box full of Turbo boards . . .

[KenLowe]

Hi Dave. Thanks for the offer, but I don't actually have a board. I was only trying to help Slo with programming a GAL to replace his overheating PAL. He's going to send me his PAL tomorrow, so I can go back to first principles, and actually generate my own equations, instead of relying on the ones posted on the other thread (here). These (and the associated .jed files that were also posted) are the ones that neither myself or Slo can get working.

If it's any relevance I'm using the Lattice GALs and not the ATMEL ones, as my programmer doesn't support the ATMEL GALs (even though the literature suggests that it does).

[Slo]

Sods law has kicked in and its another issue 4, I havent had time to finish the board off yet as i've been busy.

Dave the board is mine and it works fine with its original pal, i'm just trying to turn the heating down with a gal.

[daveejhitchins]

Hmmm! I've programmed quit a few and haven't seen any issues - very strange. Let me know I can do anything to help.

Dave H

[Slo]

Right, got the board finished and all installed exactly the same as the other machine following Daniel's great instructions annnnnnnnnnnnd

It's exactly the same as the other one, works fine with the pal and only works at normal speed with the switch the opposite way otherwise it just hangs.

So a bag of chips on its way to Ken sometime tomorrow.

Dave if Ken has no luck can you do me two please or I can send you a couple to do for me i'll send some doritos.

And failing that I don't know what to do then.

[daveejhitchins]

Dave if Ken has no luck can you do me two please or I can send you a couple to do for me i'll send some doritos.

I could also test them before sending - Or i could just send you a working Turbo board . . . ?

Dave H

Once I get the PAL decoded I can hopefully shed some light on what's going wrong!

And failing that I don't know what to do then.

I usually find that a big hammer helps at this point.

[Slo]

Dave will that be with a GAL in it or PAL? How much?

Can you believe that royal snail have gone and lost the envelope, sent it first class recorded too and I can't even claim anything (other than the original postage) as I have no proof what was in the envelope the cheeky b******s.

[KenLowe]

I'm still hopeful that it will arrive. I've seen things arrive quicker from China than from some places in the UK!!!

[Elminster]

Always a bit random from days to months. Sometimes even from the same supplier.

[CMcDougall]

^ depends on when the cargo ship sails, so if they catch day before bonus

Cargo ships take ages. Any luck it will be air mail. We send boxes via Cargo ship can take anything from 1 month to 3 months. (When they arrive)

[daveejhitchins]

The would be a GAL.

Just the GAL £1.05 + P&P

I'd want to build and test first - let me know. Or, just let me know what you need . . .
Original Slogger board £10.00
6502 £1.30
GAL £1.05
Set of pins £2.20
Build and test FOC
P&P - TBA

Dave would you mind if i post you my boards and you program my two gals and test them, i can rule out the issue 4 board being the problem if it works then, happy to pay labour and time costs thanks.

Has anyone got their old pal they can send me to replace my lost one otherwise this board is useless to me without one.

PM sent . . .

Dave H

[KenLowe]

Right. The PAL which Slo posted to me eventually arrived and I've been able to stick it in my programmer and read it as a 2716 EPROM. From that I've been able to generate equations, compile these and program them back into a new GAL. I then read this new GAL as a 2716 EPROM and compared against the version I read from the PAL. Both matched . Slo has subsequently confirmed it working in his Slogger.

I don't understand how the jed file in the other thread could have worked for anyone

Anyway, here's the equations I used. I've used the same pin labels as was detailed in the other thread:

Code: Select all

ulaa15=16 ulaa14=17 ramce2=18 romoeout=19 VCC=20 

equations

romoeout = /upa15 * /upa14 * /upa13 * turbo
          + romoein

ramce2 = /upa15 * /upa14 * /upa13 * turbo

ulaa14 = /upa15 * /upa14 * /upa13 * turbo
        + upa14
	
ulaa15 = /upa15 * /upa14 * /upa13 * turbo
        + upa15

ramnwe =  upRnW
	+ phiout

ramnoe = /upRnW

ramp1 = /uprdy
       + uprdy
       + ipirq
       + upnmi
       + upphiin

I've also attached two files:

1. SloggerTurbo.zip
This contains a copy of the .eqn file and associated compiled .jed file that can be used directly in a programmer.

2. SloggerPAL.zip
This contains an excel spreadsheet with a copy of the dumped PAL contents, decoded into individual bit. With appropriate filtering, this is what I used to help generate the equations.

Edit 1: Added the Excel spreadsheet (SloggerPAL.zip) to the attachments
Edit 2: Minor adjustment to the ramnwe equation (removed redundant /upRnW term)

[Slo]

Yes confirmed working in both machines and no hangs although ive no time to soak test it until tonight.

Dave H this has made it uneccessary to send my board as its working fine with the gal programmed with this new jed file but everything else iasked you about id still like please.

Ken Lowe thanks a million for your time patience and help. Bloody royal mail though 5 days.

[Elminster]

Did you measure before and after temperatures?

[Slo]

Only a quick knock up and test as im trying to paint a car while ive got the daylight and warmth

[danielj]

Well done!!!

So odd - I wonder if there's more than one version of the turbo driver PCB as those original equations worked perfectly in mine?

d.

[KenLowe]

Odd indeed. I asked Slo the same question about board revisions. He said that his board looks exactly the same as the one you posted a photo of.

It would be worth someone else trying the jed file I've posted. Particularly someone who's had success with the older jed file.

[1024MAK]

So odd - I wonder if there's more than one version of the turbo driver PCB as those original equations worked perfectly in mine?

Well, as there are at least two versions of the Slogger Click PCB, and at least two versions of the Slogger Pegasus PCB, it's entirely possible...
