View Full Version : Looking for Philips P3238 motherboard documentation (286 12.5Mhz)

February 22nd, 2017, 09:45 AM

I'm trying to upgrade a 286 PHILIPS P3238 to 4Mb of RAM without any success.
The motherboard has a lot of jumpers and switches.

Does anybody have the documentation?

I remember upgrading the RAM in the 1990s when I owned this PC. I do not remember whether jumper settings were required. I do remember plugging in either 70NS or 80NS SIMMs.

I reached out again to www.mur3.com who has the manuals / disks.

Hi PeterLI,

Thanks for the link, I had not found anything about the P3238 on his site.
Email sent, wait and see :)

After I called him once he wrote back. But then went quiet. :)

2 emails sent, no answer :(

Give him a phone call. He is definitely a weird dude.

OK, Thanks.

Update: hoping someone in SK will mail me the hardcopy manual tomorrow. Will probably take a few weeks to arrive. Will photocopy & scan it.

That's good news :)

Oui madame! En route from SK to the US. :)

Et voila! BTW: what did you do with the soldered in DS1287? I will have to ship it to CA to have a socket soldered in. Send me a PM in case you would like me to email you the driver diskette.

Thanks to Chuck(G) my Philips P 3238 is now fully operational.

Had to replace the FDD but that is OK. :) Not related to Chuck(G) of course. Need to source a small IDE HDD to check whether the MOBO IDE works. ;)

Ironically the mouse driver shipped with the Magnavox HeadStart 286 does not work. A random generic mouse driver works great with both a MS and Philips mouse. So weird.

Runs like a 80286; which it is! :)

Bought a 9CM053 for the P 3238. 14” CGA/EGA CRT. Hopefully it will arrive in one piece. :)

Just a parenthetical note. Peter sent the motherboard to me asking for a socket to be installed for the DS1287. This is a motherboard with a quantity of SMT on it and I considered that removing the DS1287 and installing a socket might result in some unintentional desoldering or damage to the surface-mount devices. So I modified the DS1287 in-place to use a coin cell. Easy enough to do with my Foredom tool and a soldering iron. The coin cell holder was glued to the top of the DS1287 with Gorilla (polyurethane) glue--for some reason, my 5-minute epoxy didn't want to stick to the DS1287,

Excellent work by Chuck(G). Outstanding customer service as well.

A bit of an observational note, having seen this thread play out... this thread is useless without pics or links, with two folks coordinating a hard-copy mail hand-off in public ;)

Would it be appropriate to ask that the documentation be scanned into PDF, placed on a reliable file server (or maybe attached), and posted here, so anyone with the same question in the future can have the docs available forever into the future? :) You got this far - you have the docs - maybe post it?

Updating the original post with a link to the file would be an awesome service :)

Blockout does not load past the opening screen over INTERLNK/SVR. Loads fine from diskette. Weird!

Received the 9CM053 from WY today. Works great. It survived a cross country trip. The seller double packed it and used loads of spray foam like I asked. Had to set some DIP switches for EGA on the MOBO. The P 3238 supports both analog (15 PIN) and digital (9 PIN) output. Not concurrently however. Will try to upload a picture later: not working right now.

Defender of the Crown CGA works great. Defender of the Crown EGA throws back an error message. May have to disable the MOBO VGA for it to work. SimCity EGA and Civilization EGA work great as well.

King’s Quest IV runs very nicely on this machine. I had forgotten how beautiful that game is. Sierra at it’s artistic peak IMO.

Jumpers for RAM config (in French):


RET = jumper off
INS = jumper on
