Have you tried to install all 8MB first in slot A, B, C, and D? Yep. Using 4 x 8MB ends up giving me 36MB Total (4MB from the processor board + 32MB from the expansion board), and it works great. The problem is when I try to install more of it. I have taken picture of the additional 8MB modules I …

Thanks for the feedback! After reading your comments I'm convinced that I don't "need" any additional sound device on my machine, so I decided to go for the CVX-4 just for kicks :D I've been wanting to explore this niche device for some time, and the Tandy "compatibility" through the emulator just …

Yours is an no external cache. Yet, 486 does have the internal 8K cache and still will take 64MB. Also there are caveats, this why I asked for photos of your modules. How do you know this module does not have extrernal cache? (I'm asking because I'd like to learn how to identify them myself) Go on, …

The Deskpro/M is built like this way with fullest configuration in mind from the start. This design is a processor card means you can choose any processor cards: 386DX with 16K cache, or 486 with no cache, or have a 486 with 256K (8 cache chips and one tag IC). This is interesting... I though the …

Please show photos of memory modules. 8MB modules are the max capacity, not 16MB, Those 8MB parity modules are the maximum capacity. They are 8Mb modules. I'll take some pictures when I get home later today. Second, make sure your that these modules are parity. Also has presence detection jumpers …

So... A possible solution, I used many years ago, was to use a VGA to RGB framebuffer. It take a compatible VGA signal and convert it to a RGBV TV compatible signal. Then you can use your RetroTINK-5X to up-scale the output with de-interlacing and scan line gaps to 1080p on your LCD TV. Work very …
