Lovely thread - MkArcher your cache board looks promising! I wonder if speeds above 50mhz fsb are feasible on the late era chipsets... wether UMC or SiS I never got far with optimum timings. I also tried feeding the s/rams with a slightly higher voltage but this did not provide any benefits. The …

Got two nice cases - both containing Pentium era hardware(S7 & SS7). Nice! I’d love to find an InWin A500 again. I remember I bored out the tiny vent holes on the bottom front edge to improve airflow. I think that was around the time that we all collectively started to worry about those sorts of …

Maybe 'typedef enum { false, true } Boolean;' would be a bit more elegant. Is the 'getch()' in BC++ similar to the usual 'getchar()' or similar to the one which could also be found in old Visual C?

I'm from Germany. Here I still see CRTs being offered from time to time, but mostly they are too far away to pick them up. But from my observations over the last 3-4 years they are getting rarer. And yet there doesn't seem to be much interest in them because if an ad shows up it doesn't disappear …

Two more CRTs for my 'collection'. A 17" Samsung SyncMaster 795DF and a 19" Hyundai ImageQuest Q910. Both have great specs: the 17" with 85kHz, the 19" with 110kHz. And both are relatively small and light compared to other 17"/19" monitors. (The 17" is smaller than a Sony 15" that I have) I still …

I got a 60mhz ceramic one in my first PC. In the last 27+ years I only came across gold tops... and not a single one was a 66mhz version.

At most I'd expect about 6% increase. ((850/800) - 1) x 100. Basic math. I don't know... x = (800 + 50) / 100 Next, let's define a function f(t) as: f(t) = (t + 1) * (t^2 + 1) * (t^4 + 1) * (t^8 + 1) * (t^16 + 1) * (t^32 + 1) * (t^64 + 1) * (t^128 + 1) * (t^256 + 1) Now, let's evaluate f(x) and …

Add a socket to your board if you got the tools - in the long run this may save you a lot of hassle and keep everything looking nice.

That's a very nice collection - all systems being "IBM" is really the icing on the cake(beautiful cases). What main board "powers" the 486 system? Maybe add SCSI to the P60 so that it has a bit more cycles to spare(or a PCI based IDE controller) and on the sound front a card with wave table support( …
