A DRAM tester, and a very good at it. The cool thing is that it has a NEC v20 inside ....
Wow, haven't seen that model in decades. Used that exact model or very close to it in a PC repair shop I worked at back in the early 90s. Never failed us.
Got myself a PP&S ProRAM 3000 memory board for my Amiga 3000.
Except for a month or so when I worked with a game developer who put an ethernet card in it, my A3000 never had any expansion cards.
The Most ram it's had is 6mb... with this expansion it will have 18... and if I can dig the chips up, it will eventually have 70mb!
Dunno what I'll do with all that ram, but it's something I've always wanted.
Now I just need a new video card and an ethernet card... or the ZZ9000 if/when I can afford it...
I've never been a huge Amiga fan nor have I ever been particular knowledgable about the system but is there even a use case/software on this ancient ecosystem that can actually make use of 16MB, let alone 70MB?
Multimedia stuff. I imagine a lot of music, picture, and video editing software could easily eat 8MB or more. The PC never really ran into that issue in the early days because we never had much in the way of sound... Or graphics... Or video.
Most IBMs couldn't even display color graphics, let alone play back video.
oww my back... and my knees... and my everything... 😵
...from carrying these down the stairs from a third floor office to the car... and then from the car to the basement
two Nokia 445Xi plus, one Nokia 445Xi and one Diamond P766DU.
note to self... 21" CRTs are heavy.
the smaller diamond is actually the same monitor that got thrown out of our office just a few years ago unfortunately, that one wasn't branded on front though.
unisys 486? and a curious XT case that has been painted black apparently, it looks quite nice apart from the scuff on top.
and I think my first vintage NOS items, philips CDD461 inlcuding a controller card and the other controller card we've been talking about previously to maybe get my CM121 up and running.
Pentium MMX 166 Mhz in a Socket 7 mobo with a fan, 32 MB RAM and some cache daughterboard. It's on sale for $7.5 + shipping (around $10 total). I haven't ordered it yet, but I find it very hard to resist. Is it a good purchase?
Hmm, I'm a complete newcomer to these systems, thanks for pointing it out as I had no idea VRM may be detachable. Yes, it's sold as working, the seller has POST screenshots in his listing and in a private message he did explicitly say all I need is a power supply, a hard drive and a graphics adapter to get a working computer. And a CMOS battery, apparently, that wasn't mentioned.
Although, the screenshot says "Pentium S", so it's a regular 166 P1, NOT an MMX?
So it is a regular Pentium and the board is fine for such, but I won't be able to install an MMX without that missing 5V VRM? Is it hard to procure nowadays? Is it specific to this board, or universal?
It makes me think of a PCChips motherboard. But don't worry, if I'm correct then this one is pretty decent. It may have fake cache, but it has a COAST module so no issue with that.
I have a VRM like this. You can find them on eBay sometimes, but I think someone should start making them. I can take pictures of mine so someone can make his own.
"Thanks" Hermes/DPD for nice delivery across Europe. 😒 I managed to straighten them up. Then checked for short with multimeter and plugged into wall (yeah slightly suicidal I know).
It worked, but I measured over 17V on output plug. Well it should be 12V. No way I'm going to put that into my precious vintage midi module.
So I found modern replacement power brick with similar output and it worked. So I'm happy.
To my amazement Monkey Island in Roland mode and MU50 in "C/M" not "XD" mode sounded quite OK. I need to test little more with various games. This C/M mode might work like limited MT-32 replacement.
