I installed the both a generic MGA and STB Chauffer HT in the Epson Equity Ie. Trying to switch to the monochrome adapter for text output does not work. There is no BIOS support for a monochrome adapter in the Epson Equity Ie, which for me makes it a non-starter. I am just going to leave the …

I picked up an ATI VGA Wonder XL24 video card about a year ago. It is a very versatile video card, but has issues when trying to use it an LCD monitor.

I installed a 486DLC that I had extra just to try it out. The system will not post. I determined jumper J4 is to switch between 33 & 40 MHz. I tried switching J5 but that did not change anything. At this point I am just going to leave well enough alone and run it as a 386/40 MHz system.

I picked up a PC Chips M326 v5.3 386 motherboard. What I found unusual is that it has both a surface mount 386/40 and a 386 socket. Does anyone have any experience with this specific board? I assume the additional socket is probably for a 486DLC CPU. So far it is running just fine with the onboard …

I was thinking about the relative cost of acquiring retro computer hardware. Prices on eBay of course have done nothing but gone up, but if you look at it from a slightly different perspective, it is not always that bad. Take the case of a Macintosh IIci. When it was released in 1989, the base price …

My whole point here was to do a comparison of the two CPUs under as closely matched conditions as possible. The NEC V30 will almost always be at a disadvantage because the instruction cycle counts are not as optimized as the 286 and it is in a 4o-pin package forcing multiplexing. If anyone would …

The results clearly show that even though the NEC V30 is very capable CPU, it is no match for a 286 at the same clock speed. The 286 is just more efficient and has a 2 clock bus cycle time vs 4 for the NEC V30. I have always wanted run these head to head and now my curiosity is satisfied.
