Default After a properly old laptop

Needs to have a parellel printer port and run windows 95 or earlier operating system.
(basically anything that can run in proper dos mode not load windows first then a command prompt on top)

Anyone better at searching than me on ebay got 5 mins free to look? I dont know how to limit a search to what operating system they are on

Guess you've probably tried it, but DOSBOX has worked well for me before.

How about a Dell Latitude XPi with a Pentium P133ST?

The screen is about 11.5" corner to corner and the HDD runs to an enormous 770MB of which 211MB is free, but I don't think there are any files on here!!

The battery life is really not at all good but it runs perfectly well on the mains, and the wee feet at the back to prop it up a bit are long-gone.

It has Win98 loaded, though I may have a Win 95 CD in the loft. If you need it, I have an external CD drive that connects through the Parallel port too.

It even has a PCMCIA 56k modem so you can connect to the new-fangled worldwide web from anywhere (that has a telephone socket free - if I can find the cable for it!)

Open to offers but the thing is a brick so postage will cost a bit.

Cock. I saw a suitcase sized thing at the tip that no doubt worked.

Could have made a beer out of that lol.

Wont win95 install on anything? As long as it has the parallel port of course...

ive had a proper DOS environment running on an XP machine fairly easily to run some old HMI software for an analytical laboritory ran by a proper old Mitsi PLC.
i used a USB drive, formatted it into a bootable disk and moved USB in the bios boot menu to above the HDD, and copied across command.com and the other few files necessary, can also get it to load mouse drivers etc pretty easily.
PM me if you want to try it and ill send you the info as i put it all into an email for the IT manager at work.
just had to download a HP program that sets up the USB as bootable.
i would imagine you can buy usb adapters to give you the ports you need, and call the drivers in the autoexec.bat and config.sys files as you would the mouse and touchscreen drivers.

Thanks lads

Jim, I should have thought about asking you!
Will give you a ring.

Simon, thanks mate, will let you know if I get stuck.

Its to run a BDM interface for "unbricking" a saab ecu, basically it connects directly to the main chip and just writes to it directly, it doesnt go through the software on the ecu to do it at all, so even though its been bricked (its got corrupt software on it) and wont communicate normally it can be saved this way.

Yes mate, it is indeed a 68000 in the T5 Ecu I am using, Fairly common chip for these sort of applications so Im sure its one you must have experience of?

Cracking little unit really, could potentially be relatively easily moved to other engines as a cheap way of getting mappable management on them, although you'd need to write your own software to remove the DI cartridge from the equation before it would be useful on a YB really (well either that or modify the DI hardware to fit as its actually a very very cool bit of kit!)
My assembler skills arent up to doing that but im sure yours are!
You should have gone down that route instead of creating the SECS ECU, you would have had no issues with making it then! (not a dig, I just mean it would have made your life very easy)
There are something like 20 spare IO channels still as well apparently too, so plenty of room to expand it.

Possible to run DOS from a floppy disk as well IIRC by changing the boot device to A:
So I could always do that I suppose, as it doesnt need win95 on it, just the DOS bit.

Yes I have vast experience with BDM, 68k, Coldfire in real time OS enviroments such as ECU's.

You dont need assembler skills these days as there are many cheap compact/fast C compilers that do the job nicely !

No offence taken.

When I designed my ECU, I wanted it to be 100% all my own work and it was including the alloy box !

Its nice to use ready made stuff such as what you are suggesting as it does speed up development time to a point but you are limited by its architecture.
From my personal experience you generally save time by designing from scratch provided you have the skills and tools to do so.


There are plenty of cheap alternatives that use BDM via USB and windows..

If you had bought a saab rather than a cosworth all those years ago you'd be a hero in sweden by now with the amount of development hours you put in.
and have you seen how fit swedish birds are?
schoolboy error from you backing the wrong horse with the L8

Ive not written C for years but Im sure I could quickly get back into it, however it was for the dissasembling in the first place I meant it would be useful, to alter what is there not replace it, there is no way I have enough time to write the software from scratch, that would be many 1,000s of hours I suspect, especially as I'd have a learning curve with regards to the handling of cyclic events like crank sensor etc which is a relatively specialised area (and one that I know you have lots of experience with!)
My real time programming experience stopped 10 years ago and Ive not got enough time free to start again now really unless it was paid work rather than a hobby. I'd sooner just use an autronic that only costs me a 1000 quid than have to spend 1000 hours instead, as I have more spare money than spare time sadly.

As a developer I definately prefer "green field" work as it can be a nightmare working around legacy code and architecture so I totally see your point, however I do think that the saab ecu architecture could easily do everything your S8 did though for example.

There are plenty of cheap alternatives that use BDM via USB and windows..
This is something I can buy for 30 quid that already exists, and more importantly that has the same pinouts as the board on the modified saab ecu that I have, so its not really worth me tailoring something generic to use myself as i'll only ever need to use it half a dozen times anyway probably, its nothing something I need to do reguarly as I can do normal mapping via a CANUSB lead that chats to the saab ecu.
The BDM is only needed for rescueing it from corrupt files or when modifying a new ecu (you have to force an unlocked .bin file on before you can use the CANUSB lead)

youre better off borrowing simons laptop than getting this one off me then as ive gotta source some ram, it looks to be DDR1 and i dont have any of that liyng around.

or if you can get a laptop wth the hardware then your best bet to get proper dos running is to use a virtual machine, something like vmware workstation can take direct IO control of the LPT and COM ports so there's no disadvantages to using that over having DOS as the main os.

does whatever lapop you have already hve the option to use port replicator with parallel port?

or cn you get PCMCIA or CARDBUS parallel ports? (ive never looked)

I dont have a parellel port on my current laptop, and I suspect that in DOS I would struggle with running a pcmcia one although I dont know that for a fact as PC architecture isnt something Ive ever looked into.

I wonder if it really will support DOS for very low level commands well enough like that, im pretty skeptical TBH!

it can take direct control of the IO, as oposed to what windows does, so im pretty sure id would work. would be interesting to try regardless

what error does it give when running it on CMD ? You know you could run DOS on top of windows using VMware dont you ?
