Amiga 1000 Rejuvenator Recreation Project: The Finale

[JackTheKnife]

Anyway - can someone post some high res pic where those clips should be connected to the ICs? PDF photo is not of great quality and I want to be sure I have connected to the right IC leg. Do I need to connect +12V as well or that is an option for the original Rejuvenator only?

Here is how I have it connected:



Also installation manual is talking about a jumper to set when Kickstart ROM is present but I'm not able to locate it (one empty hole but not a jumper). And should stick to 1.3 ROM on the board or go for 3.1 or something else?

Jack, any tips to share - were those IC connection wires correct? Did you populate a jumper in the position you found? Which kick rom did you end up using, or is the picture from a normal floppy-based kick session?

Sorry for the late response. Yes, those connections are correct.

I have ended up with the KS 1.3 and a jumper set to boot from KS rather than wait for the floppy (original A1000)

Also, I have switched CPU to the ceramic version

JackTheKnife, isn't it JP100 right next to the label and the single hole?

Correct. Also, I was thinking to get PAL/NTSC as a switch rather than a jumper. Currently, I'm running A1000 set to PAL.

Can I populate as 2mb but use a 1mb 8372a agnus?

Given how scarce the 8372b agnus is, I'm wondering about a board spin to either:
a) use modern cheaper ram, 1mb, and support 8372 only, -or-
b) use modern cheaper ram, 2mb, and support 8375 directly (no adapter)

But if the board can be populated with 2mb, and use either 8372 or 8375 (via adapter), I'd leave it that way (except possibly cost reducing the ram)

Fantastic, indeed.

You don’t happen to have one surplus? I am desperately looking for one such device for some time to get my Phoenixboard-Diva up and running again.

Still wondering about the above?

Also, wondering what the behaviour is if dropping a PAL Agnus into the design? Obviously won't get PAL output over the composite or rf ports etc, but what about via the Denise chip and RGB2HDMI - ends up 50Hz? Wouldn't crystals and other stuff have to be changed too?

I may have goofed and bought a bunch of wrong Agnus chips from Europe Luckily I have a handful of NTSC Agnus chips coming as well.

[McTrinsic]

Welling one of them is an Angnus 2MB PAL I can help you relieve the pain

Christmas came early

[McTrinsic]

Those are 1MB ECS types of Agnus, right?

[intric8]

The 8372A chip is the ECS 1MB Agnus.

Aren't all those 8375 318069-10 chips the 2MB PAL Agnus meant for the A500+ and/or A600?

I think someone was hoping to build an adapter some day so those chips could be used with the Rejuve at some stage. . . Definitely easier to find in 2023 than the A3000 Agnus, that's for sure.
