That's really disappointing. Are you going to try reflowing the Vram chips?

Afraid that I don't have the skill or the equipment to do so. 😿

Kapton tape, Flux and a hot air gun will do the trick in a pinch, you just need to get the ICs hot enough to melt the solder, then you just let it cool and check to see if its improved.

You can also bake the card in the oven, I've done it twice to a dying 8800GTX, the card is still going strong after the second reflow.

Today I've got a NOS/NIB SCSI CD-Writer "Traxdata CDR4120 Pro" (from 1998)
... now I need to get a SCSI controller 😉

Just won something a bit different for me (seller's photo)

s-l1600 (2).jpg

A complete Apple Macintosh LC that is dead... be a fun little project!

Had an eye on that as its very local. Glad its gone to someone likeminded! I have no idea about apple stuff but it could be an interesting project.

Yeah I'm not far away! I have no idea either on Apple stuff, especially that age! Proper gamble as no pictures of the internals, but for £30 if either the base unit or the screen work then it's worth it, but hopefully it's fixable as I've never used an Apple of this vintage 😀

Well the monitor powers on but the base unit doesn't. It looks very clean inside though.

EDIT: Ah look lower left of the picture - failed and leaking capacitors!

Bought this little thing today, a Creative 32mb Savage 4 Pro PCI, never seen this card in PCI format before but it has excellent DOS compatibility along with being a nice 3d card when using S3TC. Been after a nice cheap Savage 4 for a while so I could play around with S3TC without having to use gimped D3D like the earlier s3 cards have.

Also grabbed this Diamond Riva 128 PCI on the cheap too, adds another solid DOS/Windows card to the bench.

One of the last pieces for my upcoming 286 rebuild. It's Conner CP3000 84MB. I had 42MB back then but can't find one in good condition for the right price. So this one will have to do 🤣

Sellers photo:

Now I just need some time to actually rebuild my first 286 as it was. I already have all the rest components and even the case 😀

It's likely that I have some (and if I do they are bad sector free).

Got a IBM Thinkpad 235, working quite well and even had the surprise that it game with an ESS soundchip plus you can underclock it during normal usage 😁
Since I got all the original cds and stuff, I plan to make a backup one day (when I get a CF adapter for sd card since I have no modern ways of transfering data right now)

Also, unlike my Toshiba Satellite 330CDT, the C&T graphics card seems to be filling the screen without black borders (tested with a few games like starcraft, doom95 and quake 2) I wonder why since they both seems to be the same graphics card...

Well I'm not sure if the seller intended to throw it in there but I'm now the owner of a little Arduino development board, its one of the Uno R3 models and its got the socket able CPU in it, this little board is worth as much as the entire lot was. I guess I now need to figure out what to do with the little thing.

There's lots of project instructions around on the net for making things like USB to PS/2 keyboard or mouse adapters and suchlike. Or ways to use it as a companion chip for 8 bit CPUs to make CP/M machines or "native" implementations of TinyBASIC etc to use it like an oldschool 8 bit.

I shall look into how to use it to adapt USB to PS2, that actually sound like a useful thing to have in the toolkit, I have never used Arduino before but it seems like its a damn versatile little tool to have.

Would it work well with say a Z80 type of computer ?

Bought some DDR 1 RAM today. However, the seller had some old graphic cards and offered them to me for free, otherwise, he would throw them away. I was so happy, that I couldn't take them for free and gave him some minor compensation. Sadly there was no 3dfx among them. I think there are no particular highlights, but one can never have enough retro cards.

Finally found myself a DX-50. Don’t know if I’ll ever actually use it, but like my 286, it’s nice to have for collection purposes.

That's quite a bit of voltage for 2.6GHz

I have a few XP-M chips but didn't tested their max OC. But did test a few Opterons for s939 and one is stable at 2900MHz. Would boot at 3GHz but no dice after. Will have to decide what system I'm after...

Otherwise it's true about 1GB modules. I had 2x 512MB DDR433. Now I have a few modules up to DDR500 to play around with in the future...

Got this ASKA SST-5830 board because I wanted a compact AGP/PCI/ISA motherboard to use as a cheap and expendable expansion card test bench. Interestingly, the only Mendocino Celerons I have appear to be matching 533s I was saving for an eventual dual Celeron build, so I used a Coppermine Celeron 900 instead. Not sure if it will POST with that.. I'll have to hunt down and grab a cheap Mendocino Celeron sometime.

Via Apollo Pro chipset. Such a versatile longliver - I just saw specs. PPro, PII, PIII till Socket 370, FPM, EDO, SDRAM. Covers several epochs.

Sure will POST, but need mod. I have similar (ZIDA Tomato BX98-CT) and it is intended for Mendocino CPU only, as there is PGA370 socket. They could boot with Coppermine CPU, if you connect AH4 RESET with X4 VSS and break (isolate) AM2 KEY pins.
The connection can be a piece of wire between both pins on the back of the board. I did the AM2 pin insulation by inserting a piece of teflon sealing tape into the hole, this mod is reversible. Some peoples simply break the pin from socket, it is not my way.
Now it boot and work with CuMine CPUs, but I am not really sure, if this could work stable at FSB 100MHz, as some early revisions of Zida BX98 boards had problems with this frequency, which were only fixed in the next revision - my is 1.0. Ofc, even at 66/75/83 FSB Celly 900 (@594/675/747) will be more powerful and faster than even the fastest Mendocino (533, I believe?)

I don't think the socket mod is required, this board has a sticker on it that explicitly states that it is "Cu-mine Ready!" and has a jumprr for 100MHz FSB The issue is that the multiplier jumpers are documented only up to 8x (though I figured how to enable 9x) and I would think the BIOS, which is from 2000, probably does not have microcode for Coppermine Celerons (released in 2001).

You have better eyes, I didn't notice any stickers. My board, despite having the same chipset, did not support FCPGA Coppermines until it was modified. On the other hand, is jumperless, so it sets the multiplier itself according to the CPU (which is ofc locked), I only set the frequency of the FSB myself. For Aska I dont know.
These boards (ZIDA) were sold in 2 variants - with s.370 and slot 1, slot 1 also took Katmai and Coppermine PIII CPU, but s.370 Mendocino only.

Picked up some CRTs locally this past week, including a pair of 15 inch NOS monitors and a Commodore 1702 monitor.

The Q53 happened to be a monitor we had on our family PC, so it's got a lot of nostalgia value.

As for the 1702, it will probably find use with some old consoles I have. I'm glad it was fully intact, since I know a lot of them suffer from broken flaps on the front controls.

And some audio card pickups from this past month.

Part of these are an attempt to collect all the original h/w supported by classic Sierra games to be able to do original h/w recordings from those games. I think I'm almost there...

Auzentech X-Fi I'm thinking of adding to my ultimate XP rig.

And the classic GUS just because. 😀
