Thats great news.We are getting closer to someone connecting the ACA500 to the CDTV :thumbsup:
And hopefully selling the connector:thumbsup:

i have receveid the right connector 2 years ago from Sveta for release a pcb but i have more problem with eagle and don't can create this adapter four aca500 on cdtv

i suppose the aca500 don't work on cdtv because the aca500 load an internal kickrom and don'read extended rom, need a special update

tomorrow new test on my cdtv with kipper2k expansion

Kipper,

I'm sending it back to you to test because my CDTV refuses to boot with the board connected. No CDROM boot, no Floppy boot, just a black screen.

Initially it booted, the Ram worked fine. After half a dozen attempts at booting the CFIde with different CF cards, the red led stayed on and the CDTV wouldn't boot. Remove the board and the CDTV boots fine.

All the Cards work fine with my CDTV/SCSI/IDE setup, so I can rule out faulty cards, (and yes, I switched off the power before swapping cards)

EDIT: Is OVR pin 29 of the Gary chip?
Is INT2 pin 21 of CIA (U9)?

I have the IDE68K from MKL which I believe what kippers ram card is based on. I have some pictures on the site somewhere where I have had two wires connected to gary and something else (cant remember now).

Ive ordered a CDTV version from Kipper so hopefully I can just connect it in the same way and it should work.

Have anyone tested any of these boards with an Action Replay? Yesterday I tried an AR MKIII in my 500+ with one of Kipper2k's old 4MB expansions (I have not received this one yet), but it could not even get to the KS screen. Disconnected the 4MB expansion and it boots fine. Maybe the AR does not like the extra fast mem?

According to the schematics it should be

Gary pin #29 ovr
Cia pin #21 int2 (CIA A) (CIA B = int6)

I prefer using the Diagnostic slot, it looks an easier and neater solution, plus no soldering or removing chips to make connections. Yours is already connected so you're good to go :thumbsup:

You can get the 68 to 80 pin adapters for around £3, even less from China.

EDIT: Anyone know which is the ODD/EVEN CIA on a CDTV? ODD U9 = int2 & EVEN U10 = int6

Item received today, and seems to be working fine. Just installed it in my 500+. All 2+8MB RAM is present and it boots from the CF card. It is currently running mem tests, but after 20 minutes there's still no issues, so it is probably good. :)

I do get a PFS3 popup requester with some error when it mounts the CF partitions, but they do show up in WB and seem to work so I probably just need to repartition the card since the image I wrote onto it was from some other CF card.

Will leave feedback.

Edit: Feedback done. 1½ hours in, the memtest is still going strong, so still looking good. :)

Edit2: Just tested the AR MKIII in the 500+ with this board installed.. Not a good idea. Various colors appeared on screen and the floppy drive made a horrible noise. After this, the floppy drive wasn't working anymore. Turns out the head had gone off the spindle and couldn't be pulled back by itself. Pushing it physically back onto the tracks fixed the drive and it's working fine again. Lesson: AR does not like this board, or maybe even any uncommon memory expansion.. Consider yourself warned. :)

Thanks Kipper :thumbsup: I have received the IDE 8MB board and have it installed. Working great! Feedback has been left, and thanks again for your quality work!

Edit: @Demolition - I will keep your info in mind as I have an AR III as well. I used to think it was a KS 2.0+ issue, but obviously not after all.

Received mine a couple of days ago. Working perfectly!! Thanks so much Kipper! Fantastic product.

I read somewhere Action Replay's done't support more than 4Mb Fast Ram. Not sure if it's true - still Googling... I hope it works ok with 4Mb Fast as I'd like a kipper2k card and still use my AR III.

I have one of Kipper2k's old 4MB fastram expansions and the AR III didn't work with that either. Just stopped at a grey screen on power on. But that was in a 500+ with KS2.0, and it might be different in a 500.
