How did you do it? from photographs provided by Thermalwrong? Can you share your progress on this? :-) I actually have a working 8088 laptop with Proton chipset (see attachment). I wish I had the motherboard shown by Thermalwrong, that would make reversing a whole lot easier. As it's not a direct …

Mine yes but I was wrong with the inversion of the rows (it was already strange to me), the design of this prototype is garbage and I will have to design another.

I see... I am only asking because I also have some 5-6 of these from a project that never saw the light, I think they are reversed too... Will check just to be sure just for closure LOL Anyways, looking forward to these! Perfect. Once the project is consolidated and validated, I will publish the …

looks really nice and compact! Thanks! The idea is that the EEPROM 28C64 and associated components are optional, for those who already have IDE-XT ROM it would not be necessary. However, this socket can also be used to reprogram 28C64 EEPROMs from MS / Dos. By the way, the socket will be slightly …

I like this a lot and had similar ideas previously ^^ though my motivation isn't high enough atm to actually go through with it. did you think about making it mini-DTX instead, adding another regular ISA slot below the SBC slot? there is a lot of ITX cases that have 2 card slots so you could mount …
