Well, I got this computer for free on a rescue mission today... So I technically didn't buy it but I also didn't find it in a dumpster so I choose this thread 😉 It was rescued from the basement of a building that is about to be torn down. Last minute save, tomorrow it would have been scrapped.

This is an IMC XT/TURBO. It's a generic "turbo" XT clone with CGA, I think it runs the CPU at 8 MHz. Other specs unknown at this point but it has the usual stuff.

The monitor is a Philips CM 8533 RGB monitor which is very similar to early Commodore monitors like the 1084. I believe those were rebranded Philips monitors. Very versatile, it has a SCART input, composite, TTL RGB via a DIN plug and some other cool stuff. Would be useful for almost any 80's/early 90's home computer or console.

Built like a tank. You press two buttons on either side of the case and the hood pops up, very convenient. Check out the size of that PSU!

Right now it doesn't boot unfortunately. The PSU starts up and there are some noises from the hard drive but no POST beep and there's nothing on the screen. Will investigate.

(Also from the same place I got this stuff, all free: two vintage 70's tape decks, a stereo receiver, the first portable CD player Sony ever made, and an ancient oscilloscope)

Dang, that thing is clean! Nice save, very fortunate for you, einr! Hope you can get it up and running, and please start a thread when you do. 😀

Some W24257AK-15 cache modules that I was missing.

Thanks, I will 😀

Unfortunately some cursory examination has revealed some fairly bad battery leakage on the floppy/parallel/gameport/RTC interface card which has also dripped down onto the motherboard and seems to have ruined some traces there. I will try to clean it up but at this point I don't have great hopes for this board.

BTW the board has a "10 MHZ TURBO BOARD" marking and it has a Fujitsu 8088 so I guess it's an 8088/10 system. All RAM slots are populated too (and there's a lot of them) so it's fully loaded, whatever that means. 1 MB, I guess? 640K? I'm not super pro with XT systems.

okay that's great but i'm not sure i want to "satisfy your products", that sounds a little scary actually 🙁

My XT clone board is fully populated with 640K

Received this Belkin F1D104 KVM switch from ebay seller:

I'm eagerly waiting for the VGA-PS/2 and serial cables I ordered separately for this KVM switch. Finally I can hook up all my 3 retro PCs with just one set of PS/2 keyboard and mouse (even optical, if desired!). No more hassle with serial mouse... I've yet to find a good one (ergonomically speaking).

Nice machine!
I have a XT with the same case: Re: Bought these (retro) hardware today

Got some more PCI cards today, as well as a working Leadtek Geforce 2 Titanium. I also got some motherboards - some dead, possibly repairable, some working.

I'm testing these guys tonight. The results are going in my DOS PCI Benchmark / Compatibility thread : DOS PCI Video Card Compatibility and Benchmark tests

33MHz Cyrix 486 CPU - unfortuntatly it's a socket 3 part. Would have been cool if it was a 486DLC.

KT133 board with an ISA slot:

ECS i815 board with Tualatin CPU support - it makes a good backup in case my Abit ST6 fails.

Tekram P5MVP-A4 Super socket 7 ATX board. Unfortunately this one is dead - one of the voltage regulators popped. Shouldn't be too hard to fix if I find the right part.

I also got a Skywell AGP banshee, an AGP Trident 3D Image 9750 with SGRAM (unfortunately the Blade3D still eludes me) and an assortment of dead AT and ATX boards.

I do not need any overclocking or other options. OEM type options is fine 😀 But they must take the 3.4 GHz chips, as I really would like those result with a faster GPU.

Well, you can use a 3.4Ghz P4 with this board for sure, I've done it. It complains during boot that it exceeds the designed TDP and resets, but you can bypass the reset and continue booting pressing a key (F10, if I remember well); the VRM part gets really hot and I will not use this kind of set up for long periods, but it works.

I've seen a few posts here and elsewhere suggesting the Blade 3D are hard to find. I have 3 Jaton Video-97 Pro/4MB waiting to be tested (I have a ton of hardware waiting for me to build a shed for setting up various test systems). They cost me £4.35 for the 3! Graphics cards are my thing 😀

That's great 😀

Yea it's really just for some quick benchmarks, nothing more.

I picked up a number of MIDI modules on Yahoo Japan.

2x Roland SC-55ST (I didnt really mean to win both.. oops.. At least one is white and one is black, so they are not identical.)
1x Roland SC-55mkII
1x Yamaha TG300 (I know nothing about this particular unit, but it has a big fancy display on it, and it was dirt cheap)
1x Yamaha MU90B
and a RM602 Yamaha 6 channel mixer, to round it all up.

Once everything shows up, I am going to run them all against each other and the SC-88VL and MT-32 that I have and see which ones I want to keep.

They could very well be. Here in The Netherlands they were never really common, I only ever found a single one and it's a PCI one.

I remember its drivers being odd to install (it was in my early days of retrocomputing, so basically everything was new to me back then), but once the drivers were loaded, it did seem to work.

The Cyrix FasCache CPUs are technically DLC chips (I believe), and come with 2KB of L1 cache. I have the 40MHz counterpart with a Cx487s piggyback co-processor.

DOnt forget to replace the battery on your RTC board.. Its starting to leak..

Last week I got lots of 72pin EDO (mainly, some are FPM) memory. Around 40 pieces, about half are 16MB, a third 32MB modules. The rest is 8MB and there's also a set of 30pin 256KBx4.
Also some low density SDRAM, those will be useful in early socket 7 mainboards.

Lots of 8MB 72pin SODIMM FPM 486 laptop memory modules. The chips are mainly IBM0117800B, 3.3V, 70ns, the datasheet is available. I have not seen these at their prime as we only had desktops back then.

Less interesting but will be useful: 2 Ensoniq AudioPCI cards, and one Creative (with the 1373 chip). 3 VIA USB 1.1 adapters. Also handy for socket 7, maybe 486.

Paid some 30 euros for the whole lot with shipping.

Got a Thinkpad 770Z for $30. Ought to make a decent DOS portable machine.

Also a Biostar M5ALC SS7 mobo with K6/2-400.

Only 3 PCI and 1 ISA; OTOH has on-board ESS Solo-1 sound chip. According to the manual ftp://ftp.biostar-usa.com/manuals/M5ALC/M5ALCmanual.pdf provides "full native DOS games compatibility" Hopefully by that they mean it is connected through PC/PCI. 😀

Sound Blaster 16 CT1740 DSP v4.05 for 18$.

This is Rev.05 (059334) the last revision with v4.05, Rev.06 (069346) has v4.11 or v4.12.
I want to test how it performs compared to the later SB16 CT2230 and how noisy it is considering the CT1740 is nicknamed the "noise blaster".
But most importantly I want to test the hanging note bug and single-cycle DMA clicking.

EDIT:
Apparently the photos were not of the actual product.
I canceled the order and got a refund.

Does the white sticker on the back say CT1730 or CT1740?
