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...

So as stated in the other post I am working on an Altos 886 and in it there was a big 5,25" full-height MFM harddisk. Turns out its a Priam V150 that did absolutely nothing, which is rare for a drive, they usually make some noises. So had a look at the PCB on the bottom, all seemed ok Then...

So i have started work on a newly acquired Altos 886 system and have cleaned out a lot of dust as much as I thought was needed. Its looking a lot better inside already now and perhaps not 100% its ok for now. Next thing I cleaned, included the heads, was the floppy drive but that seems to have...

A while back I aquired an Olivetti Logos 55 for not too much and at first it did nothing but turned out that was just a blow fuse. So replaced that and lights came on but it stayed very quiet, no motor. I left it then but have now dug some further and I see a capacitor with green stuff coming...

I am thinking of acquiring two Altos machines (986 and 886) which don't boot (a swap with some other machines I have) and as I already have a working Altos 586 I was thinking of perhaps cloning that harddisk. Now, I have not checked yet which harddisk it has but if it is MFM that would be...
