Mine arrived yesterday but was left with a neighbour so I've just retrieved it! :)

Looks absolutely fantastic Ken, a real credit to your dedication and professionalism =D> 8)

Thing is though, I've become terribly distracted by the 'free with every order' packet of Haribo so sod the Integra-B, I'm off to deal with the tantalising Starmix first.... \:D/ :D

That's this first batch sold out. I've got another 5 boards available that I could build if there's enough interest. Please note interest below, and I'll see what I can do.

That's me shipped to everyone. Once you've had a chance to install and use, please feedback any comments / suggested improvements to me. If the board doesn't appear to work on initial boot, please try [CTRL] [@] [BREAK] which should give you the option to reset the board and clear the memory.

Thanks
Ken.

Hi Ken - a bit slow to respond but I would take one if you build the remaining 5 boards.

Thanks

Ok. I've got a bit of spare time later this week, so I'll build up and test a board for you with the aim of having it ready before the weekend. I'll PM you shortly with payment details.

Thanks
Ken.

I built up another couple of boards over the Easter weekend if anyone's still interested getting one. I'll give it a couple of days here, before posting them on ebay. Running short on PCBs now, and not sure if I should order up a second batch. :-k :-k

I imagine the PCBs are not cheap so I'd take names and order more PCBs if interest got over a sensible threshold.

That was just in time. I was just about to post them up on ebay at a higher price! I'll send PM with details.
Just to be clear, the IntegraB board comes with 2 x 32k SWRAM modules as standard (in banks 4, 5, 6 & 7). Do you want another 32k RAM module in addition of that?

Hi Ken
If I can be "right on the deadline" I would like to purchase one of your boards. Is postage about GBP15 to Australia still OK?

Can't message you yet. Perhaps an Admin can enable me?
Cheers

Yes. £15 P&P should still fine. I'll PM you with contact details.

@aotta
@Rod C

That's your boards dropped off with the courier. Please allow a couple of weeks for delivery.

Edit 1: I have one further board built and ready to ship. After that, I'm waiting for a couple of components to complete the final two PCBs.
Edit 2: One more sold. Remaining components received for final 2 boards, which are now complete and ready to ship.
Edit 3: Another one sold. Only one left now.
Edit 4: Due to higher than anticipated levels of interest on ebay, I've decided to offer up 2 of the final 3 that I was keeping back for myself. They're listed on ebay, but please feel free to request here too. They're cheaper if I sell direct, because I don't have to pay ebay or paypal fees.
Edit 5: No more boards currently available.

IntegraB arrived and mounted... it's a great piece of hardware!!
I am still playing with jumpers, trying to config my 62256 RAM, while eproms seem works fine.
Also, i hadn't removed the ROM/RAM wiring mod i already had in the Micro, but since there aren't ICs in the original socket, i think i can leave the extra wiring on.

Thank you and my compliments, and... i have one question (a bit OT) ...where did you find the extralong pins socket for the CPU? i am looking for one since years for repairing one of my WE boards!

Are you having problems getting the extra 62256 RAM to work?

I'm still testing the board (and maybe i don't know how to use it ;) ), so:
- the extra ram is not showed by *ROMS but it works, and BeebAid shows correctly the slots as RAM;
- i had to reset (@+BREAK) the board once, since i got "Language?" after some time;
- i can't get AMX SuperArt Working: Roms are loaded while booting but "*pointer" is not found. Tried several *osmode options too.

Is it normal?

Anyway, i planned to test IntegraB with one of my Beebs without the DIY SW Ram Mod, , as i am afraid it may interfere with your board.
Thank you and again my compliments!

So...

1. Is normal. Only the 4 preconfigured banks show as RAM. I am hoping to write a utility that will allow you to specify your additional RAM banks, so that *ROMS does report these banks, but I've not done that yet.
2. Is not normal. However, it is possible that some programs may corrupt the private RAM area that stores the IBOS parameters. You can always save and restore the parameters with *CSAVE <filename> and *CLOAD <filename> to avoid having to manually reconfigure all your parameters after a reset.
3. I'm not sure about AMX SuperArt. I've got the ROMs (AMXSP & AMXSPS - I think?), but never known how to use them. I assume I also need some disk based program too? If you can give me some pointers, I can check it out
Edit 1: Think I'm actually talking about a different AMX utility called Stop Press! Anyway, if you could post up a copy of the ROMS / Disk Image, or point me to where I can download them, I can take a look.
Edit 2: I've just located and downloaded AMX SuperRom 3.41 from here and installed that to RAM bank 4. I get a valid response to *POINTER. If I do *POINTER ON followed by *ART it starts up the ART program.

Thank you Ken! i've just made same test with Rom 3.31, and it works if manually loaded!
My fault was using probably the Master version ( the one you can found here: viewtopic.php?f=32&t=5222 ), and it probably loads from disk ROMS not compatible with B.

So, all fine with your boards!

Ok. I've written a small RAMSET utility which is a BASIC program that allows the user to inform Integra of any addition RAM that is installed in the system. This will adjust the reported amount of memory in the Startup message, and will adjust how the *ROMS command reports the ROM banks (the E/P flag becomes enabled). Once set, this setting will remain active until the utility is ran again, or until a Integra Reset is carried out.

Thank you, i think it'll useful! but can you give some help about how to use it? in basic it doesn't load, and *RAMSET hangs the Beeb..

Oh. Sorry about that. I was having a couple of issues saving it on my GoTek, but thought I'd solved it. I'm currently out, but should be back shortly to fix it.

You don't have to excuse, it's really kind of you writing a tool like this!
and, i have added a NEC 43256 32k RAM too, it works fine!

Not sure why it's doing that. I've tried it on a couple of machines without any problem. I've made a couple of slightly different versions for you to try:

RAMSET2 - Loads machine code into a DIM area
RAMSET3 - As 2, but this one doesn't try to auto reboot.

Can you test these and see what happens.

Might be worth doing an Integra reset again, and also *UNPLUG some of your other ROMs, in case they're having an impact?

Edit: File removed. Please download file located on first page, which is confirmed to work.
