Glad to see the upgrade having gone that well. Thank you, keropi, for taking the time to experiment even down to risking your own hardware. Really glad to see our efforts paid off. This opens door for anyone having a MegaPC and wanting a 486SLC upgrade, even though the performance increase is really …

Some news on my side. I managed to dump the BIOS of the PC7486SLC80 using another method as the NSSI one proved not to be reliable (it only dumps a part of it). I removed both high and low BIOS chips and used a TL866II-Plus to dump their contents. Both chips were properly identified by keropi as …

Because I might be wrong in identifying the correct pin the keyboard controller, here's the front and the back of it (click to enlarge):

You're welcome. @phipscube: That's a 16-bit version of Opera. It turns out to be the most "usable" browser with that machine (most up-to-date, most functional but still prone to crash). @Zalog: The patch wire goes to pin 19 of the keyboard BIOS socket (labelled "KEY", possibly keyboard controller), …

That said, it's possible we may get BIOS images from another MegaPC Plus out there, or another possibility which may be easier to get hold of is the BIOS from the Amstrad PC7486SLC80 (where 80 is the HDD size, not speed). If anyone has photo's of the motherboard of that PC, please let me know as …

Crap, I'm seeing this only now. Sorry for the bumping but what I'm posting here could serve as a reference for other Mega PC or 7386SX owners. I've managed to fit a 20GB hard drive in my Mega PC (which is identical to a PC7386SX, but with the additional Mega Drive ISA card) by selecting a "User" …

Hello all, I hope I'm not bothering and that I'm posting in the right section. tl;dr version first : looking for ADT (I think that's how that frontend menu is called) and the computing tutorial explaining various things (equipment, accessories, how they work together, etc.). ---------------- The …

Indeed, that did the job. Thank you very much again. I deleted every folder containing any possible activation files ("Activator" and "com.roland.Activator" folders notably) and now I'm no longer getting the "expired" message. However, depending on the games, the "trial mode" message may trigger …

You did reply me on the Youtube video. Thank you very much for the feedback. I managed to make it successfully work with one of my machines by following what you exactly advised here. I first installed the 1.0.0.3 trial you pointed on a second Windows 7 machine. The activation worked flawlessly, …

Working in XP?! All versions of SCVA I have tested DONT work in WinXP (no sounds). All legitimate versions of SC-VA work in XP but only in trial mode. So the 10 min/session restriction is active, but the 14 day limit is not (most likely because of the activation component's incompatibility). Edit: …

Please excuse the necrobumping but I have a very interesting info regarding Mega PC owners who lost or don't have their original Amstrad monitor anymore (the exact model is PC14DSM). If you wish to use any kind of monitor (CRT VGA or SVGA, a regular LCD monitor, etc.), I found a device that works …
