Pour tout ce qui touche au PC d'IBM et ses nombreux descendants. Attention tout de même, au delà de quelques MHz la discussion devient vite hors sujet.

The 65 model is an evolution of the 60 model. If it uses the same case, the motherboard is very different (SIMM support, many connectors onboard).
Thanks for the info. Indeed the boards are very different.
I had though that the Micral 65 had a smaller case but with a similar design, like the 45 that came out the same year.
I'll create a separate topic on the Micral 60 when I start working on my model.

I'm wondering what is the added external connector on the 65. Maybe for a Bus mouse?

I will see but I cant remember ever having seen any Bull like videocards, or videocards with Bull stickers.
I got my Micral 60 with an original video card: a Paradise CGA/MDA switchable combo re-branded by Bull (sticker at the bottom of the back, marked XPU J93). Could be that the same one was used on the 65, or maybe an EGA card.
Oooh, its a normal paradise card and a short one, that made me think.
And yes, another VGA card, an 8-bit ISA card I pulled out a few weeks back because I thought it was a waste in a system with 16-bit slots turns out to be a Bull rebranded one (sorry for the dark pictures)

Interesting! An 8-bit VGA card: that's quite uncommon.
What was not uncommon, though, was to have 8-bit graphic cards in early AT systems such as the IBM 5170 and its clones (among which are the Micral 60 and 65). I think having this one in your 65 would be more fitting and you'd still enjoy the features of VGA
I believe the 16-bit bus was more used for other types of cards at that time.
Yes I will place it back, it belongs in there.
And I have more 8-bit ISA VGA cards and I even think I have another paradise one so I can equip my second 65 also with the right card
Though on my side I was thinking to fit my Micral 60 with an 8-bit EGA card and use the CGA/MDA in one of my IBM 5155 since it has the composite Berg connector for the internal monitor. Even if it's a bit of a shame since it has the Bull sticker not to keep it there, it's an upgrade that would have made sense back then (that and an Adlib card ).

Hey, I know that this tread is old but I have somewhere original manual for the Micral 65 in case that You need to get other answers regarding this system.
