At least for similar Compaq and hp PPro boxes the memory modules does not need to be installed in pairs. Did you have a closer look at the memory sockets? These caused trouble in some of my machines. To clean them you can use a piece of cardboard the thickness of the memory PCBs, soacked with …

I have a P60 board for the Deskpro /M but unfortunately it does not work. Tried it with the original backplane it came with as well as in a different machine.

Got the original action reply somewhere from a bunch of parts, but never installed it in any PC. I was not aware the board has such extensive features and that there is major request on it. Good for me that I did not sell it on ebay yet, but kept it in storage. Will have to dig it out, to check the …

The PS/2 floppy drives are well known for failing capacitors. see also https://www.vogons.org/viewtopic.php?f=46&t=46462 Been there, done that. Good job. Replacement with a standard drive will also spoil the front panel view. IBM used special drive fillers not compatible with standard drives (apart …

The driver will not load, because the system is not able to insert to the token ring as long as it is not connected to a MAU like an IBM 8228 or something equivalent. There are token ring switches availiable as well as token ring boards with 100 MBit, but without an ethernet to tr bridge you will …

The 4000 allready has AGP grapfics but with a proprietary slot cover, while the 6000 is the PPro edition of the Deskpro. I was able to grab the graphics memory upgrade as well as the 100 MBit Network …

The link shows a backplane for PCI/ISA SBCs. The SBCs have the PCI bus behind the ISA slot. There is like VLB no way to get a PCI bus attached to the ISA bus, nor does it make any sense. Instead PCI to ISA bridges were used on allmost any PCI mainboard.

The Deskpro M is a nice machine, I own several of these myself. The only backdraft is that it uses lots of proprietary parts as many other Compaq machines of that aera. To your questions. - The only way to use a DX 4 is an interposer socket that might collide with the memory board. The Compaq …

Did not know about the actual prices for the Reply Board. Got my system years ago from a fellow MCA-collector for cheap. http://ps-2.kev009.com/ohland-old/misc/mcmaster.html would be another option to upgrade to 486, but may be as hard to find. Got at least one in my collection too.

The classic 50 and 70 are limited due to their DBA ESDI drives. If the 16 bit limit doesnt mattter the 56/57 are quite worth a look, they …
