Hp 500b Mt Ram Upgrade

[Torie Crivello]

Iam planning on turning this computer into a free NAS system however I need 8 GB of RAM for this to work,at what is the max RAM I can use for this computer and any other workarounds if I can't upgrade it

Hi, I have problem while i am upgrade ojs from 3.3 to 3.4 first error said

the composer does not support php version

so i change it to php 8.1 then i get the error HTTP ERROR 500

any advice ??

Finding the proper one will take some time. You need to check all lines and figure out which one. In case you lack the skills, use the 50% principle. Create a module2 folder, and move 100% of your modules into it. Than start moving all modules 1 by one;) Not a perfect solution, but figuring out what is causing the issue, as well which module can take sometimes hours.

No, I didnt clean old modules. By moving 100% modules you mean that root folder should be emptied?? Then when I move one module back to root/modules folder should check error log (and keep doing that with others)? If nothing found in error log, for this particular module, it mean is compatible with installed PS version?

Upgrading the store from PS 1.7.5 to the latest 1.7 shouldn't have generated such issue. I don't have time right now, but on Monday morning once I'm in the office I could check - in case that is an option. Not getting a closer look, and from what you shared is almost impossible to figure out the issue.

compare your modules folder with the one from the prestashop archive (download it if you don't have it already) then rename one by one the extra modules in your folder (not in the archive) and test if the problem is gone after each rename; when you find the culprit rename back the others.

Yes, one line is missing (active). Now, when i click ADD it sending me to this screen (bare in mind, I`m completely rookie with this and I dont want to do even bigger mess). Which fields I should fill? Thanks

It seems that error gone. I had another one with database connection. I sorted this out. Now I see login screen but it stuck in loop. In Dev mode when I try to log in I get white screen in the middle after login. Should I delete cache from the VAR directory?

You are missing more DB fields (id_shop in table mod875_log in this case), there seems to be something really wrong. You can continue to add them one by one but there will be still risk of future errors or inconsistencis

By the way, in folder /modules/autoupgrade/upgrade/sql you can find all the SQL statements that were supposted to be executed during upgrade. If you can't go for a restore I would check these and apply to your DB manually if required, these are not so many coming from 1.7.5

You'll need of a whole bunch of older PAN-OS versions that are no longer supported in order to upgrade your device to the latest supported PAN-OS version for your PA-500 (which is PAN-OS 8.1 btw). You will not find these old PAN-OS versions on the support portal anymore and your best chance is to contact support so they can provide you with the necessary content and software versions from their archive.

Much like the Sinclair ZX Spectrum I fixed up, the Amiga has a special place in my heart. I'm not alone in this, by a long way. For folks who were into computers in the late 80s / early 90s, the Amiga was one of the most interesting. Much ink has been spilled on why this particular computer is so special. Jimmy Maher in his book, The Future was Here makes the claim that the Amiga was the first multimedia machine. I think that's a fair assessment. It could draw amazing graphics, play great sound, run great games, desktop applications, paint packages - the whole sheebang!

Folks like Ahoy, Kim Justice and many other folks have done some pretty good videos on the history of the Amiga, so I won't go into too much detail here. Suffice it to say, the Amiga has it's time but was hampered by poor business decisions and a hardware design that didn't evolve enough. Nevertheless, there are some folks like Steve Lord who have attempted to use their Amigas for modern day tasks, replacing things such as IRC, email and playing music. This might seem crazy but Amigas don't have the same problems modern PCs do. While you might spend time and money to update a 30 year old machine to work in the modern day, you'll never have to worry about spyware, ads, lag or malware (for the most part).

I had an A500 back in the day - one of the most popular models in the UK. It came in the Cartoon Classics Pack - bundled with some software such as Deluxe Paint, Bart Versus the Space Mutants, Lemmings and, unfortunately, Captain Planet. I loved it though and I have a lot of nostalgia for it. Sadly, I sold mine back in the day. I never thought I'd miss it.

I bought another on eBay and decided I'd like to upgrade it for the modern day. Some things about the original Amiga were annoying - such as the disk loading. But these were problems of the time and not limited to the Amiga alone. We can get around these rough edges today and get the best of both worlds.

The first thing to do is to clean this machine. It's definitely yellowed a lot! I don't intend to retrobrite this Amiga; I'm told that retrobriting doesn't last very long, and besides, even though I live in Fife (the sunniest part of mainland Scotland), retrobriting would take forever! So I figure just a quick clean with detergent and car shampoo to get rid of all the grease and dirt should do it.

The plastic on old computers can be quite brittle so it's important to take care when taking such things apart. I cracked part of the top case sadly. I managed to fix it with a little plastic weld, which worked a treat. You can barely notice the join. The next challenge is removing the keys from the keyboard. Most are quite easy with the proper key-puller, but the larger keys have a metal bar holding the key to the board. You have to pop and slide the key cap to get it off. This is tricky with the space bar, having the longest metal rod of all, but the worst is the return key. This has two metal bars mounted perpendicular to each other. A real pain to deal with!

Wet wipes took care of the gunk and gunge on the keyboard proper. A good scrub with a toothbrush and cream cleaner made short work of the case. Sadly, I lost the warranty void and factory stickers in the process which was a shame. I tried to remove them and failed. I probably could have left them on during cleaning as they were pretty firmly fastened to the plastic. Oh well.

The motherboard was quite clean, with no signs of corrosion or leaky capacitors, which was good to see. I did buy an A500 as a present for my sister some time back that did let out the magic smoke when it was plugged in, so it's always good to check these things.

There are several ways to upgrade the core of an Amiga these days. The PiStorm is the latest craze I believe? There are flicker fixers, Wichers and a host of other options but I went for the Apollo Vampire A500 V2. It does an awful lot of stuff! Not only does it replace the CPU, but it replaces the ROM, adds compact flash and SD card support, HDMI out and loads of extra memory! It's an incredible bit of kit, but one needs to sign up to to a waiting list in order to get one.

Installing it is super simple. You need to remove the original CPU and ROM chips. I used a chip pulling tool and a flat bladed screwdriver. If you are using the latter, be aware this is not the best method; it can cause damage to the legs of the chip. I tend to twist the blade slightly, then move to the other side, or other end of the chip and repeat. I only lever at the end when it's almost out. Seems to work well.

The Vampire needs to be firmly pressed into place. Once it's in you can lead out your HDMI cable if you want. I'm not using HDMI on this Amiga, at least not yet, so all I need to add is the compact flash.

Hard-disks for the Amiga seemed super rare to me, in 1990s UK. They were huge, and slotted into the side expansion port. These days, we have more storage than we know what to do with, so we can have the hard-disk of my dreams using the Vampire's IDE pins and a compact flash adaptor. Firstly though, we need a cable.

I thought I had the right cable - I have a load of IDE cables knocking around. However, the cable I needed was a 44pin laptop IDE cable. Such a cable has 4 more wires and a smaller pin pitch. Oh well. I found one on ebay eventually, along with a compact flash to IDE adaptor. The adaptors were quite easy to find but the cables seemed quite rare. Very odd.

The whole thing sits on-top of the vampire card. I put the assembly inside a small plastic bag in order to stop any bare metal parts touching. The whole thing sits nicely under the RF shield. It does mean swapping out the card is a pain; one needs to undo the entire case. It can be handy to install directly onto the card from WinUAE or similar. However, it'll do for now. If I find a longer cable, I might use the side door expansion and find a way to mount the adaptor just above the old edge connector.

The A500 predominantly uses 3.5 inch floppy disks. Yep! For you young'uns out there, this is what the 'save icon' is based on. Each would hold 880K (this was the case on the Amiga. Similar disks on later machines would hold a bit more). Some games would come on many disks and swapping them in and out was a bit of a pain

I never had access to a hard-drive back in the day, or even a second floppy disk drive. Disk swapping was not a fun part of the experience. I'm not aiming for reliving the Amiga days 100%. Rather I'm trying to keep the good whilst getting rid of the bad. While disk swapping and the glorious noise the drive made are part of the authentic experience, I'm happy to let this bit go.
