Would anyone know what 72 PIN SIMM 2M X 36 I would need for my Magnavox 286? I would like to boost it's RAM from 1MB (on board) to 8MB (SIMM). The manual does not go into detail on this.

Wow... that's an odd choice of RAM for that vintage motherboard...especially since those are both 16-bit processors. I wonder if it's even a standard pinout.

Details. I'm pretty sure you want something like the pdf description of this Cypress 2Mx36 RAM. (http://web.mit.edu/6.111/www/s2004/NEWKIT/datasheets/CY7C1470V33.pdf) (j/k). Does it have any particular brand in it right now? You'd at least know that works or could look up any specs if there are any concerns.

I didn't think 72-pin SIMMs even existed yet when 286s were still being made! What year is the computer from?

Thanks. Let me check the MOBO and manual this evening. The PC is from 1991 / 1992.

That's what the online manual indicates. Max of 8MB (if you disable the onboard 1MB jumper). But yeah that's pretty advanced. I thought the 286 era was mostly SIPP or 30 pin SIMMs.

Hey, posting reading material *sideways* is really counterproductive. :-)

IBM did it with their Model 50Z too. Single 72pin SIMM bank.
It's a 286, 1988 I think.

It turns out HP made a bunch of these for printers so I will experiment with one of those. Just have to buy and receive it. :D

the real question that should be asked here is whether or not it is proprietary ram. a 286 / 386sx mb with 1 72pin simm slot seems rather advanced for 286s, I don't even think they were around yet *correct if wrong here*

Got the 8MB 72PIN SIMM today. Works like a charm! :)

Nice. Pics need to be roted though.Hehehehe... I never understood why some individuals post pics like that when it's so easy to post something that we can actually view without going through contortions. :-)

I still have to figure out how to rotate using an iPhone / iPad. :)

U/l it to your computer and use the computer. That's what computers are for. :-) :-) :-)

I remember seeing the 386SX version of that Magnavox computer in an electronics liquidator catalog (Damark, I think?) from around 1993 or so.

Cool. There were a bunch of versions. They were all Philips PCs rebadged for US/CA. :)

Tap the edit button, then the lower left button will rotate, easy peasy

I remember them in Montgomery Wards back in the day. I also remember the same place carrying a Commodore branded 286 and 386 laptop. It'd be cool to have one of those.

One of my friends worked at Kwiktrip in the 90s, when Kwiktrip got rid of the 286s around 98/99 she bought it cheap, had a 25mhz 286 processor and 4mb of ram, worked quite well, blasted thing still had a 60mb hard drive though. I loaded it up with Windows 3.11 goodness, it ran about 2 years then wouldn't post anymore.
