A few months ago now, I came across the not so rare (at least here in Italy) pile of old PCs and miscellaneous material, outside a school building, obviously waiting to be withdrawn and demolished. Luckily I had seen it before the retirement, so I went saving the salvable, including 2x M24-marked Olivetti desktops - not the classic, famous model, but the more modern 'remake' based on Pentium 133.
Waiting for cleaning and restoration.
The two samples seem identical, apart from the presence of an CDROM in one of them, and different aesthetic and wear conditions. The side handles, those that allow you to open and slide the upper part of the case to open it, have proven to be very fragile and weakened by age: in one of the two models, they immediately shattered. The CDROM unit, for its part, did nothing more than enter and eject continuously, once the machine was powered. The hard disk of one of the two never worked during the tests, while the other one worked the first times and then lost data and no longer allow the correct start of Windows 95, installed inside it.

PSU unit.
The motherboard, after a good cleaning. 8MB SIMM installed.
The VGA is integrated, by Trident, 2x empty memory socket to upgrade video RAM capacity. In the middle, the additional slots riser with 2x ISA and 2x PCI - the vicinity of them make me think that they can not be used at the same time, they probably have shared resources ISA1/PCI1 + ISA2/PCI2.
AMI nice graphical and mouse-enabled BIOS.
Testing IDE2CF and 2GB CF as hard disk: it works!
After the POST.
One of the two machines in the riser had mounted an ISA network card, stored now in my warehouse. In the sample I chose to keep, I brought the total RAM to 32MB SIMM - now the intention is to mount a Matrox Mystique that I have in reserve, instead of the integrated Trident, and a beautiful Creative Soundblaster, maybe an AWE64 non-Gold also unused. Then I will proceed to the installation of MS-DOS 6.22, maybe together with Windows 3.11 (I saw some photos of Windows 3.11 the other day, and I got a lot of nostalgia - my main choice is still pure DOS). Does the choice of Mystique seem to you relevant enough? Just to not use the usual S3, I would also have a TSENG 4000 ISA, but maybe it is not relevant for this machine.
SpeedSys in progress.
The two motherboards, apparently identical, are different for two small details. First of all the shape of the heatsink on the integrated next to the CPU socket, of different shape and size - another detail that differentiates the two machines is to be found in the RTC chip Dallas present in one of the two, while the other one has a normal button-battery connected to pins not present in the other specimen:
Dallas RTC in machine #1.
More common battery to save BIOS options in machine #2.
First comes smiles,
then lies.
Last is gunfire.
