Hi @nexxen - apologies for the necro-post, but I was wondering if you got this EGA card working? I am curious if you were able to find out anymore about it. By dumb luck I stumbled upon a Compaq EGA monitor. I already have restored an original 1986 Deskpro 386/16. It seems those were offered with …

Here are some pictures of it. How much is it worth? The value is going to vary by how far away the person is from you getting it. Shipping of a compete system like this can get quite expensive. I can see each part selling for around ~100 each, but then shipping starts to add on the price. It'd be …

Spraypaint is in most cases my choice, when retrobright failed or did produce "spotty" results. In such cases, I use this two colours for painting old cases and drive bezels: a) In most cases: RAL 9002 grey white, silk mat does the trick. b) ... or, if a bit more beige tint is required: RAL 1013 …

Hi everyone, I've posted here before about something like this I think, but wanted to solicit some feedback, or perhaps rally some folks together that are much more talented than I am to maybe make this dream a reality. So, it's no secret that it's getting more and more difficult to find PSUs for …

I have [re]discovered the solution to the "1740-fixed disk 0 failed set Block Mode command" issue. Turns out this error isn't just encountered when modern humans try connecting compact flash adapters to these computers. Our fore-bearers faced this scourge when connecting non-Compaq hard disks as …

Yes! I just found one locally. Mine is the 5528. I caught the bug to get one of these after seeing the older one LGR has, and it reminded me of these little all-in-one computers. The one I have has had a journey it seems. While it still superficially looks really nice-- underneath the plastic is …

This is power resistor not capacitor. There is a shorted IC somewhere that was fed by this resistor. So you're saying my likely issue is a failed IC on the board and this thing blowing is a symptom of the problem not the actual problem? I was hoping this was another case of a leaky/busted cap. I …

Hey everyone, So I recently got interested in these old Iomega Bernoulli drives. I've accumulated a number of them now... at couple each of the 20MB, 44MB, and 150MB variants. They were all SCSI... or so I thought... until I realized one of the 150 MB "Multi disk" drives I have is actually IDE (or …
