The twist works together with the drives DS (drive select) Jumper wich can be set between 0 and 3. Usually it is set to 1 , thats why you need the twist. Setting it to 0 should eliminate the need for the twisted cable. There were configurations with 2 devices on a single cable. 2 FDDs and a tape …

Unbuffered EDO DIMM was common on PPro platforms while many Compaq serveres used buffered EDO Dimms and even buffered FPM. Some systems like the Vectra XU use 5V buffered EDO. Some IBMs from the 300/700 series had memory slots for PS/2 as well as for a single 5V buffered EDO DIMM. Got some Kingston …

Additional to the Heatsinks, removable Bios Chips and Jumpers I frequently harvest the battery holder, that can be used to mod worn Dallas chips. Caps are just harvested if they are non standard format, like these extra slim ones. Sockets only if there is an actual need for a replacement.

Congratulations to the board especially to the dual blackheads. Got the same PC Server 365 board some years ago and installed it in my PC Server 315. The 315 hat the same board, but only a single socket 8. The same type of unbuffered EDO DIMM memory can be found in some other PPro based systems too: …

From my experience OPTI and SIS based motherboards use generic cfg-files, as long as no special onboard features are used. So any OPTI-Mmotherboard cfg should work.

VLB graphics for sure. EISA-SCSI Raid for HDD Storage, I would use a DPT. Adaptec EISA SCSI for CD and/or tape storage. EISA Networking Ethernet (3Com, Intel), token ring (Madge) and/or FDDI (DEC, SK-Net). EISaMulti serial (DIGI) ISA soundcard if the SCSI RAID is not noisy enough.

There are some other machines using the same type of memory. Namely the Compaq Proliant 800/850r and the Netserver LHpro. Both are dual PPro systems same as the PC365. Especially bigger modules like 128 MB are hard to find and expensive. I might have some 32 MB spares, if you are located in Europe. …

Check the memory sockets and try to clean them with an IPA soaked piece of cardboard. Memory problems can be caused by the modules as well as by the socket. BTW. the 365 is a really nice machine. I upgraded a single PPro server 315 with the board of a 365.

The 1542CF is the Flash Version of the 1542C, so there should be no need to remove any chips for an BIOS/microcode update. The 1542A, B, and C have removable EPROMs that require erasing and new programming in an EPROM-burner device. As written before one chip is BIOS while the other one is microcode …

Complete systems may be another choice if you are not bound to AT format. Intergraph TD410, Dec Prioris MX6200, IBM PC Server 365, HP Netserver LHpro, HP Vectra XU, Compaq Proliant 800, 850R or 2500(R) come to my mind.
