I read the zidefs' guide, but !hform patched give an error "number too big" when computing Sec*Head*Cyl*Park... i made a patch to bypass the error, but when program finish the disk is not recognized as formatted. With the only "partition", if previously formatted the SD card with the Rasperry, it wo...

i made one IanS IDE card (IIC, it sounds good!;) and it works... only one time! :roll: if i format with raspberry a microSD card, then i partition it with zidefs tool, then i got harddisc0 and i can use it perfectly... since a reset or power cycle. At reboot, disk is empty and not formatted. May be ...

I hope mine will work forever too! Anyway, psu is one of the simpliest parts to replace, and i used sometimes picopsu inserted into original psu.. Less weight and more efficiency!

my burner accept only .jed files for GAL programming, and i didn't find an easy tool to compile source if3.PLD posted by IanS: anyone can attach the jed files please? Try the attached file - I've just created it with WinCupl so haven't been able to test it etc. Thank you very much Rob, i spent hour...

Tested with Sirbod's patched 2.68 ADFS, and with a real IDE HD (the Maxtor 20GB, is the "oldest" HD i found at reasonable price.. ;) ), but no difference: formatting finish without error, but HD is still "not understood, may be not formatted?". It's probably the battery acid is the cause of this, bu...

I am still trying to format some drive for my A4000, in wich i repaired some tracks damaged by the famous battery leakege.. now i got the drive recognized fine, but no sdcard formatted with raspberry is recognized by the A4000... Formatting in the A4000 side, the ADFS way seems work and format the d...

And i always go for a few pounds more, if it let me avoid working with i psu and crt monitor..
I am working on repairing my a4000 too, but my focus is now in the ide connection..

Fyi, on the bay there are a couple of A4000 psu now.. Not at cheap price, but original and working...

If you have misspelled card identification, you probably still have some broken/shorted tracks.

thank you ianS, i tested continuity for all ide port pins and remade 3 broken. Now all connected pins seem ok, some idea for what check other than continuity?

i tried the boot wizzo posted here with my A4000 inernal ide port, after some rewiring due to corroded track by battery leakege, but i can't made it working, tested with a lot of combination of sd / cf / adaptor. Best result with the Sandisk 256 cf mentioned above (but !format recognize it as "SaOdi...

Wow - good work :D Thanks danielj, but no work at all, i will leave this in the box as i bought it! for the dirty jobs, i will use one of my other pc128s, wich is filled with turbommc, videonula, mouse adapter, ecc. ecc... :wink: but about working... the A4000 in the background got a lot of my time...

A new from old stock Olivetti Prodest 128S, the italian remake of Master Compact tried by Olivetti.
With new warranty ready to fill with my name...

The A4000 only has an internal 8-bit expansion (and on-board IDE, like an A3020).

Ops!!!
so i can delete 16 bit version from my to do list until i'll find the right Archimedes... but i could use 2 of 5 pcb ordered, if i won't to repair the onboard ide port.

Which version are you making?

I ordered pcb and components for the 8 bit version for my A3000.

But I bought few days ago from ebay a A4000 with battery corrosion (and hd and floppy not working), and it is on the way from UK... so the 16 bit version is in my todo list too

What a detailed answer! it's a pity i didn't have a teacher like you in my computer class
I can't wait to receive pcb (and all components) and test it! My compliments to you and John for the project and for sharing it

about the rom, it's not clear to me how to burn the 3 rom you linked into the sst39sf040, and how the 2 switches works (they select upper or lower rom's part to use?)
Thank you Ian for any help to understand your board and to make it!

Thank you very much Ian, you did a great work and you give a way to many Archie's to have an Ide disk, nowadays so difficult (and expensive) to found!

i use turboMMC with my compact, but i must admit that i am fallen in love reading about beebscsi project... as said, just ordered the pcb, but closed farnell page (italian ones) when prompting me a checkout of over 70 euros with tax and postage... i need save some money for restoring an A4000 (with ...

If you're in no rush, I've used airmail with jlc and it turns up in about 2 weeks in the UK :) (I think the mosfet is the fiddliest of all the things on there!) d. i can wait and just ordered the pcb from jlc... and adding components to my farnell basket but... considering the minimun quantity for ...

Thank danielj and simoni, great hints, specially the site for ordering pcbs... For smallymouse pcb last time i spent about 30£! I will place orders for board and components today!

i love solder and working over old pcbs, but this new one boards need solder point too little for my eyes... i can give a try for myself, but not intend to project a batch for reselling: i will probably burn more component than i will be able to place! If someone else is interested, perhaps we can c...

oh no... another great project i found just after last board is sold??

If you can keep cost at reasonable level, I think DOM will be an interesting plus! I'd like it

A PCB to allow me to test -8-bit podules in an Archimedes. (I don't want to wear out the connectors in my A3000) IMG_20180519_163958301.jpg (my first non-rectangular PCB!) And some new 8-bit IDE podule PCBs, now with room to fit a DOM on the 44-pin connector, so no cables or adapters required. IMG_...

Great! And in 8 bit version, 5v on pin 20 need extra wiring too?
Waiting for your next batch for testing!

Oh no! I missed this 3ad since now.. In list for an 8 bit version, hoping in a New batch!

Really? if RobC is working in the project, i can believe it... i bought one of his Nula for my Master and it's a masterpiece! anyway, the emulation on arduino seems a good alternative to me... i'll investigate about the possibility, starting from emulator that supports ICS IDE in software and that a...

Also, it looks like the header cable that comes with the programmer will be of limited use - as the pin out doesn't match exactly the layout of the pins on the NuLA board. Instead, I'll need to take individual jumper wires from the programmer direct to the NuLA JTAG header. Does that sound correct?...

I am afraid the original project will never get progress... But i have just finished the porting to arduino of the apple ii smartport emulator, and i am quite sure it may be done for emulating a3000 ide podule too... I start studying!
