ST-IDE-ROM Dev Board v1 - BETA Testers

[rubber_jonnie]

All 3 boards are tested and working. I think the 2 dev boards have a few bodge wires on the back, but are otherwise good once I drop a suitable ROM in. The one I do have installed has TOS 2.06 and Emutos.

Did R1C have bodge wires on the bottom ? Looking at my files I did other revisions...

R1F looks like I got those made at JLC, but no idea if those were tested.

Board on the right is the R1C.

Thanks, yeah there is some swapped pins on the R1F, so likely those wire fixes. Also looks like a huge layout tidy up as well.

I will have to build one up at some point. They be useful for H4 and original machines I suppose.

I do have a couple of H4s, I should get on with them and I at least have these IDE boards to get on with. I will possibly throw them in my Megas though.

I've got a couple of these to build up too, think they will need bodge wires though :roll:

I'll add them to my virtual retro job list...

One thing to bear in mind though, I have no idea what firmware goes into these things any more.. unless it is posted in this topic somewhere...

Possible maybe @rubber_jonnie could read and dump the versions he has at some point, firmware may all be the same, but no idea after all these years..

I think the CPLDs (If that is what they are) came pre programmed form you exxos, unless of course it's far enough back that I don't recall programming them...

All I remember programming was the DualTOS ROM. I certainly don't see anything related hanging around in my Atari folders.

If you tell me what's needed to read them I can certainly give it a go.

I'm pretty sure I got the PLDs pre-programmed too as part of the kit, complete with the exxos stickers on them!

I'll try to dig them out in the next day or two to confirm but I don't think I have a programmer for those PLDs.

@JezC @rubber_jonnie Can't really remember anymore.. I might have assumed nobody had a ATMEL programmer and pre-programed them.. If you have the PLD already then it be a matter of following the threads to see what mods were done..

If the chips came with the kits, then there's probably no point doing anything @rubber_jonnie Theres no more of those boards out there AFAIK.. and if chips came with them anyway..

The firmware definitely changed a fair bit in the last revision (R1F). It looks like I was trying to use the smaller 1504 PLD, but it wouldn't compile, so I had to move a few pins about to get it all the "fit". The last code revision looks to match the last PCB revision (R1F) so I assume it was just left an estate workers literally need building and testing..

Pretty sure I don't have an Atmel programmer, certainly not for a CPLD that size. I think my TL866 does smaller Atmel stuff, certainly can't cope with anything that big. Doesn't the board have a JTAG header? Could it be done using that?

Yeah its the larger connector next to the PLD...

Problem is I don't know if the chips were protected or not.. Quite possibly they are protected... But I guess you could see if your programmer would even recognise the device..

Though at the time I was doing this stuff you had to had the official ATMEL programmer... Maybe things have changed now.. @agranlund @PhilC ?
