Alrighty, I suppose I'll just make a few of these for a personal project since there doesn't seem to be much interest. Thanks for the feedback. :) As to using a resistor network, no, because each individual control line has to have its own resistor going to each segment --- a resistor network has a …

I used to think I had Asperger's, but then I found out I was actually just Slav. ;D Whatever you do, don't take the pills. I don't know about asperger pills, but for depression... Vitamin D is essential - most people have deficiencies and taking it can't really do any harm, but can actually really …

I just use compressed air for removing loose dust and dirt (and by compressed air I don't mean spray can propane from computer store - be eco friendly). Then I use PCB Cleaner in the spray bottle and ESD safe brush. I put the board on it's side on some paper towels, spray alot of PCB Cleaner and …

If somebody asks me about one single most useless thing in the retro computers - it has to be the LED clock display. If taking such effort - why not make it actually usefull and show real CPU clock speed for example. Simple arduino powered frequency counter will measure up to 66Mhz with ease - which …

Excellent deal :cool: Enough until end of time? :lol: These DIY SIPPs though ;d I have …

I've been in a bit of a retro pc shopping frenzy lately... Still being on the hunt for a decent AT midi tower case for my Tyan Trinity based SS7 build, I came across a nearly complete system on eBay (seller's photo): s-l1600.jpg This is Morex case. I own one since it was new (still looks very …

Nice Morse Suntac motherboard! No need to hurry with the battery removal - if it didn't leaked yet, it's not going to anytime soon. It's GP anyway and they don't leak or just get a little corrosion on the terminals.

The trace above the fifth hole on the left top seems undamaged to my eye. The solder resist is abraded but the trace itself should be perfectly fine. Overall it's not a super clean job but I think you did adequate for a first try and I absolutely believe it will function 100%. I don't see any …

Also this minitower. I bought this PC mostly because of this case - I wanted to have one for a long time. It's in nice condition. Unfortunately BAM-12 (Suntac) 286 motherboard is beyond repair due to corrosion. ST157A HDD doesn't seem to work as well. IMG_20191107_170030.jpg IMG-20191107-WA0025.jpeg …

Jeez, lots of XTs for you lately huh? I'd be interested in any extras you may come across. Need spare DRAMs and EPROMs, and past that I think they're kinda neat to have.

That's one ugly-ass, cheap generic case. Look for 2000-2004 cases from Modecom, eBox, Tracer, Logic, InWin, Gembird, Codegen and other horrible cheap brands like these... maybe you will find something similar. Keep in mind these cheapest cases were branded differently depending on the country and …

These TurboXT systems seem to flock to me recently... This one I bought really cheaply (good stuff - two 360kB FDDs was already removed). Unfortunatelly NiCd battery on RTC card did leaked (as you can see). I don't really expect this motherboard to work. I bought it mostly for the case. Also the …

It's not overblown. I would say ESD is number one cause of computer components dying right after overheating (and maybe in case of retro machines - NiCd battery leaks). I keep all my stuff in ESD shielding bags and handle it like dionb described. I also use ESD-safe tools whenever I can. Good video …
