Recently I got this Quantex 486DX computer with a PC Chips/Alpina M919 v3.3B/F motherboard. Turns out it's infamous for having fraudulent Level 2 cache! A few companies were doing some shady crap back in the day with fake/dummy cache chips. Not only that, but it goes so far as to lie and say that the cache is *actually* working when it's not, and apparently there's even some kind of lockout where you can only use their proprietary 256K COASt module. Wow... Luckily, a modern reproduction of the M919 256K cache stick exists and I've got one. Let's try it out!

Here's where I bought the new cache stick: https://www.ebay.com/itm/203544350953
