I had an A500+ and a A1200 Magic back in the day. Wish i still had them. Your doing a great job and love watching your videos. Keep on the good work and keep those ladys alive! Greatings from The Netherlands.
Hey Chris. We all thank you for putting in the time and effort to keep them all alive! I happily donate to that cause. As always, keep up the Good Work.
Wow Chris 😮 This looks challenging.. Will be definitely be following this with baited breath. Could this be a sign that other A4K’s could go this way? I currently own 2 of them 🤞🏻🙏🏻
Any thoughts on why a WarpEngine won't boot if any memory is installed? Yellow screen, blinking A4000 powerled, stuck in reboot cycle. Works perfectly fine when all WarpEngine memory is removed. Tested with the original 040 and 040-060 adapter. She was running fine with 128MB of 60ns RAM (4x32MB). After a few recent hot days, she stopped working. Cleaned contacts, reseated RAM, tried other sizes and combinations with appropriate jumper adjustments. Reflowed solder on the SIMM sockets. Originals were replaced with metal restraint sockets. One stick of any memory, in any socket, will prevent her from booting. Anyone have schematics to trace SIMM lines? Thanks.
@@ChrisEdwardsRestoration Thanks. I'm running some real-world speed tests with MovieShop to see if my WarpEngine 060 at 68mhz without memory is faster than my T-REX-II 060 at 50mhz with memory. If the WE wins, I'll keep it in my A4000. Otherwise, we may be going Jurassic with the T-REX-II. I'd like to keep this A4000 an all MacroSystem set-up if possible though.
@@ChrisEdwardsRestoration Is there a benchmark list for SCSI controllers? How fast is WarpEngine SCSI-2 vs T-REX-II SCSI-2? I'd have thought CSPPC/060/MKIII SCSI-3 would be the fastest though.
@@jjdigitalvideosolutionsllc5343 there used to be years back, but that website went down . i think bboah and amiga.resoure.cx list them but not in a "list" the GVP T-rex2 was the fastest, even over the phase5 stuff. GVP did some sketchy stuff to bypass normal amiga limitations.
The 1.5MB chip ram is a clue - it should be 2MB so probably address bus issue around that area - I didn't see a chipmem test? Try a manual one from 0MB - 2MB ? Should start getting errors around that 1.5MB...
"Scouring the world wide fungus" lol As a friend of mine would say, "I love the way your brain thinks." :) I trust that someone will make another Paula chip available for you.
Its been a long time but I have had a CIA cause a Green Screen on an A500 which is not an A4000. I will be following this closely because I do own an A4000 and knock on wood its still working but all Classic Hardware is is destined to fail maybe not today but certainly some day in the future. Every time I open up one of my babies I always say a prayer. I only know one thing is something stops working I have to take a deep breath and figure out what I did or failed to do or what did I fail to reconnect. Yea all my babies are on a KVM Switch so if you leave say the keyboard disonnected the mouse may not work and ya know even my KVM Switch pinches a fit too. Yea been down that road far too many times I now have spark 8 and 16 port KVM Switches because failure is not an option. Yes the insanity continues even here in the Bible Belt where even Jesus would not chose to live.

Another great video! Your Amiga suffering and troubleshooting makes my day. 😂
Keep up the great work on saving Amigas!
Thank you Chris. Cheers
Dr Chris is the Beautyfarm for your Amiga 😉 He brings the old Girls back to Life again👍🏻🤩
Chris, I watch you like a good show. You're like Don Juan fighting windmills (but you win). Greetings from Poland.🤘💪🍻My bad Don Kichote.
Quixote.
I've never seen that diag method before using putty. How is it connected to the Amiga?
Serial cable to usb
I would have thought you would have racks of replacement chips/resistors/capacitors/sockets......?
I have many but these things are super expensive
Our friend Acill swapped out my Warp card plastic clips with metal memory clips. Nice now.

At least this one showed signs of life my others are clean but dead dead dead nothing at all no matter what
Buster Rev 07 in a A4000?
They came w rev7-11

Unfortunatly no however
Retrorewind.ca has xray machines and stuff that can look for breaks in lines. Either that or it fried a logic chip

@@jjdigitalvideosolutionsllc5343 t-rex2 has the fastest
Scsi ever made on the amiga

I'd love to see a modern popular youtuber technician VS one of these
I had 256MB SIMM in my Blizzard A1230.
Long term, some FPGA chips are going to need to be programmed, like with the Commodore 64.
The 1.5MB chip ram is a clue - it should be 2MB so probably address bus issue around that area - I didn't see a chipmem test? Try a manual one from 0MB - 2MB ? Should start getting errors around that 1.5MB...
It gets better stay tuned
