I worked for ICL from 1983 to 1992. From 1983-1989 I worked as a componenet level electronics repair engineer at the Central Spares & Repairs workshop in Stanier Street, Newcastle Under Lyme, Staffordshire (1983-1986) then the workshop moved to Bradwell Staffordshire until 1989 when I moved to …

I would also go for industrial grade CF cards. The advantages of industrial CF cards is that they come with more reliable single level cells (SLC). If you install any Win9X or WinXP on them it might be worthwhile getting industrial CF cards as their longevity is longer (they can endure more read- …

@ i486_inside Nice project. Looks like you have invested quite a lot of time into it. What did you end up doing with the system?

@ dionb Just out of interest. So the remaining 4 banks need to be fitted also with identical SIMMs. If the first 4 banks already take up the 32bit bus what about the remaining 4 then. Also, I know it's non-sensical with a 386 CPU but just I was wondering if with this backplane a PCI graphics card …

@ dionb Just to make sure I understood correctly. So I have two 4mb 30p SIMMs installed right now. In order for the SBC to boot I will need to install another 2 4MB SIMMs? The 4 SIMMs need to be of identical size and speed (60, 70 or 80 ns)? Thanks!

@ dionb Indeed, thanks for confirming. I was actually wondering about that. Excited as I was when I unpacked the SBC I just put in the only 30p SIMMs I have. Thanks for pointing it out!

Here a higher res pic of the SBC.

Regarding the backplane I was wondering if anybody knew or had experience regarding voltage setting. Do I have to do something here. What are the functions of these screws?

I got the SBC today. What I didn't know or see when I ordered it is that is has 2 PS/2 ports which was kind of unexpected. Turns out the SBC is from the British company ICL (defunct in 2002). It features an 385 33 chip which as far as I understood was primarily useful when using a NOS (Network …

I know! This was my assumption as well and thought that this could be the ultimate flexible Retro-PC. Having the board in an AT or ATX case I thought this could be one of the most convenient ways of changing retro-PC configurations. You basically just change the SBC and boom you have a completely …

So the problem could be solved with a SDL to DIN cable for the Model M keyboard?

I have experienced something similar. The model M with original SDL- PS/2 cable would not be detected by my ASUS VL/I-486SV2GX4 motherboard. However, on my DFI Socket 7 K6/2 motherboard it worked perfectly. I did some superficial research and the best explanation I've found so far was that the Model …

Hi, I'm fairly new to PICMG Blackplanes but when I came across a i386 SBC (photo attached) I was curious whether I could build a i386 PC using a passive PICMG backplane with some other ISA expansion cards, like I/O controller, VGA and soundcard. I'm still waiting to get all the pieces delivered. So …

Sorry for being away for so long. Here some pictures of my motherboard. I hope you can clearly see here which wire was attached to which pin on the PS/2 connector.

@ chrisNova777 I had the same problem. This is what I found with regards to the wiring of the StarTech cables: red - gnd brown - data yellow - clock green - +5V I plugged the individual cables onto their respective pins on the board and it worked with my Intelli PS/2 Mouse.

Hi, I'm rebuilding my old 486 DX/4 PC and I have problems getting the CD-ROM Drive connected to the system. If I connect the IDE cable to the CF IDE Card reader (Master) and a CD-ROM Drive (Slave) (tried several) the system won't even boot. I have a GENOA SYSTEMS VELOCE 8600 VLIO combo graphics and …
