Does anyone know what this device is ? I am guessing its something used by a service engineer and probably for BCS series as I had some more items for these but no idea further. See https://stefandump.stack.storage/s/VA0k3894et9QCe2d

I have for sale two old stock in box Burroughs BX-1000 Beam-X vacuum switching tube's The box and tubes look like they just came from the store but are 100% untested Some pictures of one of them can be found here, if seriously interested I will take pictures of the second one too...

Hmm, yes I noticed the empty socket too. Documentation is going to be a pretty difficult search probably but all I can do is keep a look out for it. Or perhaps find someone with a UTS40 to see if that at least matches.

@Chuck(G) A pretty high res picture can be found here : https://stefandump.stack.storage/s/tj0IxqWym9cD3xdW

Ok, so the floppy / disc controller card makes the error go away and a DSDD 5.25" drive seeks (the original drive is a Tandon TMS100-1). The videcard also produces a really nice clear colour picture on RF. But I have been unable to boot any of the disks with the DSDD drive I had lying around...

Its alive (just turned it on with the single PAM card) : All it took was a stock laptop with serial port and straight through serial cable. Sometimes things are so simple :) The shown error is ok because the floppy controller card wasn't installed. That will be the next step, or perhaps first...

Would I be correct to think that the PAM card would run on its own and perhaps show some output, seeing the PLA port goes to a port labeled TERMINAL ? Because that would be a good point to start to see to get something out of it (less is more).

Ooooh, I didn't knew that, my memory said the D780 was some floppy controller chip or something. Didn't even look it up, shame on me. I found ads for their PAM boards on archive.org : https://archive.org/details/PersonalComputerWorld1982-04/page/170/mode/2up?q=%22%22hi-tech+electronics%22%22

I saw and I am wondering if the case I have is a self made case or customized case from the original (as it has that vibe a little bit) and that the internals are the CP/M extension as mentioned in the brochure and you can see on the 3rd page. It certainly does roughly look like the same shape...

I found the keyboard in a Sperry Univac brochure which seems very very similar (but is for a terminal) : https://archive.org/details/bitsavers_univactermUTS40TPUBrochureJun82_2279819/mode/2up

Uhu, heavy too :) It came with one floppy that was stuck inside the drive (which I didn't notice as it was really pushed in with force and all crushed up) which reads : D E C O S UNITEX REL 2.0 10/83 AZERTY It actually came from the French part of Belgium so that explains the azerty keys.

Some pictures here : https://stefandump.stack.storage/s/HG04UVEv510eNn24 (taken over a few days so different sceneries ;) )

Will make some tomorrow Chuck

So I have acquired this S-100 bus system and I know nothing about S-100 bus systems but the label on the front reads Sperry and the label on the bottom reads Univac D 60 60. It has cards in it from an English company called H-TE Ltd. All boards from 1982. The Tandon drive is broken but trying to...

I only work with brochures I own, so physical brochures :)

Sending PM :)

Even though I still have plenty more brochures to scan I am always on the lookout for more brochures so if anyone has any that they would like to part with, please let me know. They will eventually all end up here : https://classic.technology

Just to let everyone know that I know have added a functionality where you can subscribe to a specific category (=brand) so if you are really into IBM for example you can now simply subscribe to IBM and you will receive an email when I scan a new brochure and put it online. Just simply scroll...

I have this 5160 power supply that I would like to use but the fuse inside immediately burns out. So first thing I would like to check is if the fuse that was inside is the right one; T2.5A, 250V Could anyone verify ? Also, are there are parts that are known to fail ? Ow, ps, not an...

So I bought some random ISA cards and one of them is this ELSA XHR Spectra 134. I was expecting to find info easily as ELSA is a well known brand and everything is labeled etc. But alas, no go, nothing to be found on this card. So I am hoping someone here could supply me with a little more info...
