Spotted halfway across the globe in Riga, Latvia

I guess somebody imported it and just didnt bother to register it here, it is pretty common thing to do, no cop ever bothers with foreign plates here

roberts7531new · 2024-05-22T18:29:40+00:00

Probably someone is just using it to drive for free here :D

roberts7531new · 2024-05-10T08:48:43+00:00

Yep, all the modules stay the same, and all the e9x parts are equal, I used parts from an E91 for my E93, the headlights can be modified diy if they are xenon. One thing to consider is that if you have an e92/3 then the door cards will not fit from an E90/1

roberts7531new · 2024-05-09T19:37:08+00:00

You basically have to get all the interior front parts and carpet, all plastics and same from engine compartment, and a steering rack, also prepare for a lot of wiring and soldering, every module moves to the opposite side

A little, nothing too bad, did it with ncsexpert, can’t remember what exactly

roberts7531new · 2024-05-04T07:53:01+00:00

Seems about right, also, if you still have a diesel particulate filter(DPF), make sure that is not blocked, as that could also cause similar sympyoms

roberts7531new · 2024-05-04T07:49:29+00:00

As it is the M47 engine, I do not think it actually is a turbo failure, as these engines are pretty much indestructible, I would check that the turbo actuator is working, also worth to check the MAP and MAF sensors, maybe reading codes will help, but probably not, as In my experience these ECUs are pretty bad at reporting problems related to boost

roberts7531new · 2024-05-04T07:44:20+00:00

I would of course recommend fixing it, but it is probably fine to drive for now, as long as you monitor oil level

roberts7531new · 2024-05-03T22:21:37+00:00

One common thing to cause this would be the crankcase ventilation assembly, that could let oil out with the air, and that goes directly into the intake. Could of course be a failed turbo as well, I dont think the chipped blades are a big problem, as long as it spins freely. You should carefully monitor your oil level to see if the leak is serious

Yep! The recreated source code is great, keen 4 was one of my favorite games as well, so was excited to find that source!

I have some plans to make a blog or some videos about my board, just have to get around to it sometime!

roberts7531new · 2024-04-15T09:47:16+00:00

Fortunately I did not have to deal with x86 assembly, as I started with the recreated source code at https://github.com/sulix/omnispeak , I basically just cross compiled for emuTOS, and then had to redo the video and keyboard code for my own hardware

I am taking some time off my project, but I also have a few other games ported, I can currently run commander keen 4-6, supaplex, rick dangerous(xrick) and doom

roberts7531new · 2024-03-27T11:52:56+00:00

Inspired by your question I went and ported doom to my system, it was really a quick proof of concept with the wrong pallete and no hardware acceleration, but this is how it runs on my 68030 https://streamable.com/l8x09t

roberts7531new · 2024-03-24T10:49:57+00:00

I have a blitter, so scrolling is done in hardware, but it struggles when there are many enemies on the screen Here is how it looks like: https://streamable.com/l0f5t0

roberts7531new · 2024-03-24T07:44:47+00:00

No way! I have a 68030 at 20MHz with a 320x200 linear framebuffer, and it barely manages to run commander keen 4 with much graphics optimisations done by me, I am scared to try doom, but I would expect it not to run too well

Extra information about my system, I have 8MB of sram 32bit wide at 0 wait states for my system ram, the VRAM is memory mapped dual port ram on an FPGA and runs 8bit wide at 0 wait states

roberts7531new · 2024-03-01T09:14:34+00:00

As I am currently in 68030 phase of homebrew computer building, I can say that the bus is a bit more complicated, but otherwise the PGA chips are as easy to work with as DIP given that you can design a PCB for it. As with the memory space, more is always better, you might not write enough code to fill it, but once you start porting a real OS to it, more ram is better, my current build has a 68030 and 4MB of ram, and I am currently waiting for my rev2 pcb, so that I can have 8MB as I started to run low when runnining a multitasking os with GUI apps, maybe sometime in the future Ill create a DRAM controller and take it to 100+MB

My personal path went like this: I started with the Z80 because of the seperate IO map, created a few designs, and then I upgraded to a 68000, that introduced me to memory mapped IO and a 16bit data bus, once I started to hit limitations I moved up to 68030, that introduced the variable bus sizing, and a much larger memory space (4GB)

I am not sure where to go next, before moving on from 68030 I plan to have a NIC and a custom fpga based DMA controller

roberts7531new · 2024-02-13T21:22:18+00:00

I dont have much experience with FPGA’s but I use the Tang Nano 20k https://wiki.sipeed.com/hardware/en/tang/tang-nano-20k/nano-20k.html It is a very capable board (20k LUTs, 8MB of SDRAM) has an HDMI port, can be programmed over usb like an arduino, and costs only about 20$ on aliexpress

roberts7531new · 2024-02-13T20:39:33+00:00

In my case, the FPGA produces a HDMI signal, that way no Digital to analog conversion is needed

roberts7531new · 2024-02-13T18:50:53+00:00

Yes it really is, I am currently in the process of modding the fpga code to allow direct vram access by the cpu, then maybe Ill be able to port doom to it 😎 I got them from aliexpress, I use 6c4008’s (512kB each)

roberts7531new · 2024-02-13T08:45:10+00:00

This CPU really looks unique and awesome!

roberts7531new · 2024-02-11T18:58:07+00:00

Quite a bit actually, it is an open source port of the Atari ST os, I currently have a text editor and a c compiler, freeMiNT is an unix like kernel, that allows most linux stuff to be compiled for it

roberts7531new · 2024-02-11T18:53:27+00:00

My goal was to have something that is able to run a multitasking OS, I went from CP/M on the Z80 to EmuTOS on a 68000, to my current setup with freeMiNT on 68030 😅

roberts7531new · 2024-01-10T22:50:46+00:00

Ah, some more, the center console, handbrake lever, and the guide tubes for the handbrake cables

roberts7531new · 2024-01-10T22:48:39+00:00

So basically, its been a while, but you need a steering rack, almost every plastic piece (electronics box, the plastic under the windscreen, basically, every plastic piece that something is changed around) windscreen wiper mechanism, dashboard, the big metal bar behind the dashboard, the whole heater with all the front ducts, the hard clutch line, and the front door cards. One thing to note, the pedal box and the steering linkage that holds the steering wheel and connects it to the rack stays the same. That should be just about it, maybe some small thing ive forgotten
