I always do what I can to try and help the local community with their Amiga woes and when one local user reached out looking help with his battery damaged Amiga 500 Plus, well I said I'd do what I can.
Not just as bad as some but the battery has spread its contents over a fair bit of the board and there is some damage to repair but that's not the only surprise this machine is hiding. Something called an Vortex AT-ONCE is hiding in the CPU slot and Gary looks like he's made a tower to escape the battery poison.

Not sure why I tested the low pass filter in my A500+, its got nothing to do with the chipset 😆 and while not shown here, I did soak test the board for a few hours and everything works as it should 😁

Great vid as always, One tip is to cut small sections of solder wick and hold it with tweezers whilst heating with soldering iron. Using solder wick while its still on the roll will soak up loads of heat from the iron and away from the joint.

Fantastic video Glen. The 385v cap in the PSU are typical for switch mode power supplies where the AC voltage is converted to DC. It allows for extra tolerance in the RMS voltage. Give that EU voltages are typically 230V AC + 10 % this would give us 253V AC. Once it goes through a FULL WAVE RECTIFIER 😅 it would give us approx 356V DC. The overhead is built in as some supplies do break the +10% limit especially in the UK. Decent power supplies typically use 400V caps but most cheaper ones for the EU market use the lower 385V ones since the voltage is typical 220V. I've measured 262V AC at home sometimes which used to pop old light bulbs.

I mentioned to you previously that i picked up a mac 128k and an a2000 to restore. You asked for an update so here goes. Mac 128k recap and retrobright complete. Works 95% (problem with the crt vertical circuit). A2000 is up and running, just waiting for upgrades to arrive so I can use it. Had a leaking battery but all the filth on the board seemed to have soaked up the majority of the goo. Thanks again for inspiration!

The 128k and the A2000 sound amazing. Good luck with the CRT, I unfortunately don't know enough about them to offer any advice, just be careful if you open it up. The 2000EATX has become my favourite Amiga, I'm always using it and with the pistorm it makes a very powerful system. What upgrades did you decide to go for?

Next, I'm debating between a terrible fire and a Pi Storm. I like the terrible fire for the IDE interface and non emulated 68k cpu, but I'm not sure how much that matters? What steered you towards the Pi Storm?

I bought a Amiga 500 Plus motherboardoff EBay and my plan is to make a mod for the Amiga 2000 for it. I found you can upgrade the 500+ to 2MB chip, 1MB fast and around 1MB ranger RAM through a trapdoor and Gary adaptor. Interestly I kind of thought this a little odd and wondered how difficult it would be to add this as an option for the Amiga 2000.

I had no idea about cleaning with White Vinegar. I have a few RPC's (6 & 700's) that're suffering with battery leaks and I was tempted to just bin them but after this, they may have another life. The other bit about re-treating with common solder is another boon. Thanks for this and I owe you a pint.
@CRG
@CRG 11 месяцев назад
Just depends on how far gone they are from the battery spill. Any heavy green corrosion won't really lift but it's always worth a try. If you do expose any copper always either treat it with solder or new solder mask or nail polish will also do. Just make sure it works first before you paint it as getting it back off always leaves a mess (speaking from experience) I'll hold you to that pint 😉

Over a dozen trace repairs removal and replacement of the sockets for Paula Gary FatAgnus and the ROM. and most of the glue logic in the aria replaced. Got it going in the end tho. That was long before replacement PCB's where available, now id probably go that rout with one that bad.

I have the upgraded Plus version of the ATOnce for my A500 (main differences are a 14MHz 286, onboard 512KB of dedicated PC RAM, and a 287 FPU socket) and at the time in the early 90s I mostly used it for my highschool homework that required PC software not available on the Amiga like using AutoSketch for PCB layouts for electronics class and running the Turing programming language for CompSci class. You're right in your assumption that games are definitely not what these boards were designed for, the main issue is the emulation of the PCs video card is done in software on the Amiga side and the translation to the Amiga's video output is *very* slow. You definitely want to be using CGA or Hercules mode to get any kind of usable performance out of it and even then it's not really fast enough for action-oriented XT era games. Best you can get is about half the character rate of a stock XT in CGA mode and as you observed there are definitely some compatibility issues as well. You can just about run slow-paced games like the original Space Quest, Gold Box D&D games, etc but even there the slow video output is still pretty noticeable. The EGA and VGA modes are also mono 2-bit modes only so only really good for productivity apps (or running Windows 3.0 if you really want to punish yourself) even if you ignore how much slower they run. Something that does help (a bit) though is if you have some FastRAM in your Amiga as that will be allocated to the board first and does help performance a bit (although the video output still has to talk to CHIP RAM, obviously). Other things not touched on in this video is it does support using more RAM to not only provide the full 640KB for DOS but also 1MB+ memory like any 286 and also supports using the Amiga's mouse (with an included DOS driver), serial, and parallel ports from the PC side of things. HDD drive support can work in two modes, either with a dedicated PC partition / drive or using a hardfile on an Amiga partition. You can also use a RAM/RAD drive if you have enough memory in the Amiga as a small PC boot drive for faster DOS performance.
@CRG
@CRG 11 месяцев назад
Thanks for the info. Since making the video I was able to come to an agreement with the guy who owned it to let me keep the ATonce. I may save it for DOScember but it will appear again and as you say hopefully with some fast ram and maybe a HDD installation it might perform a little better. If anything we'll be able to spend more time with it and hopefully get it setup better.
@LeftoverBeefcake
@LeftoverBeefcake 11 месяцев назад
I also have the Plus version, which came as a nice unexpected bonus when I got an A500 off eBay a few years back. Unfortunately I never got around to testing it, since the Amiga itself needed some TLC to get back up and running, and there wasn't much in the way of utility disks for the ATOnce online. Also I have exactly zero PC software to use with it. One of these years I'll throw it back in the machine and give it a proper test.
@noggin73
@noggin73 11 месяцев назад
I also had the ATOnce plus (still have it but not the A500!). The hardware was great but the software was crap. Why wasn't the 512Mb available to the Amiga when the emulation wasn't running? (it's real fast ram!). Why was the DOS text mode using 640x200? I wrote my own hacks for this. - A copperlist to stretch the screen to 640x256 (don't think my old A500 was capable of 60Hz but could be wrong) - Add the 512Mb after the ATOnce software started. I've since learnt it's because the ATOnce FPGAs (or whatever they use) are loaded from disk.

Great video. You were wondering about the Olivetti and Toshiba 3100 video modes. Well, during this time there were many standards about for more capable video modes than CGA. Olivetti had one such in their M24 series of computers and likewise Toshiba's 3100 laptop (pr maybe luggable) also had its own video type. It's interesting that the ATonce can emulate these because these were quite rare. Other such proprietary systems include Amstrad's PC1512 and the Plantronics card which was used in Commodore PC clones. David Murray aka The 8-Bit Guy did a video not that long ago about these Super CGA cards, well worth checking out. I think his game Planet X3 now supports most if not all of these graphics modes, and PETSCII Robots supports Plantronics, IIRC. Fascinating time for sure.

I once (AT-Once?) had a second-hand Vortex PC emulator expansion for the Atari ST, though I never got it to work. I'd actually bought the ST second-hand also, just for Oids, so that was consolation enough. From the looks of things, I didn't miss out on much with the PC emulator, and was very pleased with my first real PC, a Pentium 75 a few years later. (Even that's 30 years ago in 2025. I'm getting too old too fast; I wonder if I can soak myself in vinegar, IPA, and get recapped!)

I was able to work out a deal with the owner of this system to keep the ATonce, so I will revisit it at some point along with some fast ram and a HDD.

@CRG

It depends very much on what the damage is. For something like the damage on the 500 in this video its easier to just patch it were its broken against the hole but if it was the middle of the trace somewhere that had broken or if there were multiple breaks in a single trace I'd probably just use a patch wire on the underside. The single core wire is ideal for either solution, I find it easier to work with when compared to stranded wire.

It would be really great if you could put the text you add to your videos at the top instead of adding it to the bottom of the videos. When you add text at the bottom of the video it will be hidden behind the subtitles/CC. Sometimes you actually do add the text to the top. 😄

Never thought about the subtitles but noted for future, any on screen text will be at the top👍

An alternative method I have seen to protecting exposed traces is to use some nail polish which just gets painted on.

Yep that will work too. The only issue is if you later find another fault it can make a mess taking it off. I've used it before though and like to use clear when I do, shows off the copper underneath 😀

I don’t know why people recap 500s the original caps will probably outlive us all on those machines, its only the cheap ones from the 600 1200 and cd32 that need replacing

Yes it might have been redundant but still doesn't do any harm.

why would they leave any traces visible, sink them in the pcb completely
@CRG

That would mean extra layers and extra cost.
