Can 16bit ram work with 32bit ram

spanner · 13 July 2012, 16:16

I searched for this and couldn't find the answer.
I have a PCMCIA card with 2meg on it and a Alfa ram card with 1 meg on it.. http://www.amibay.com/showthread.php?t=31684
Can they work together..?

yes, but you will slow down your processing ability by nearly 10% as it has to use the 16bit chip path for access to the PCMCIA

this can be a trade off if you are wanting more memory for OCS/ECS WHDLoad games - however you may notice under performance when running specific AGA or 020 required titles.

It has a 68882 25mhz FPU in it too,will that work ok too or can it stop WHDLoad games working..?

im pretty sure that card you linked to spanner is 32bit,the fpu will make absolutley no difference to whdload games.

and i think that card takes extra memory upto 8 or 9mb in zip ram form.

I know I just got it today and don't have the money at the moment to add 4 meg to it so I want to use it with my 2Meg PCMCIA card for now.

ahh,i see then it should work as long as you dont go above 4mb on that card.

spanner · 13 July 2012, 18:04

OK i have put it in and the workbench crashed a few times but it seems to be ok now (Fingers Crossed) Just got to try a few games and programs and hope everything is alright.

Edit: I just noticed that it says this in the manual..

"Never have the jumper “J7” set to the right when having a Quartz on the board. The Amiga and/or
the MemoryMaster 1200 can be destroyed."

The quartz is the FPU right..

j7 was set to the right on the board...

roy bates · 13 July 2012, 18:26

just remove the crystal and the fpu and set the jumper to the left.

edit: oh wait that what i said may be wrong i havent seen the manual,have you got a pic of it?

No sorry its wrong silly me

Jope · 13 July 2012, 18:54

The quartz is not the FPU. If you purchased the card in that amibay link and it still looks exactly like the seller's photos, you do not have a quartz oscillator installed.

Here's what a quartz oscillator looks like:

It fits on the empty socket right under the FPU.

ok thanks

Retrofan · 13 July 2012, 19:37

Congrats mate! You've got a ram board to get all the WHDLoad games working finally!

Yesterday I ordered for my Amiga with the Amitek an ACA 1231/42, so I will sell the Amitek. Now you can sell your Pcmcia ram too, and the ramboard was very very cheap.

spanner · 13 July 2012, 19:49

Dam it I keep getting boot errors and program failed.

"Supend or Reboot"

Then the software failure red Guru on screen..??

roy bates · 13 July 2012, 20:10

is the machine ok without the harddrive spanner?

Retrofan · 13 July 2012, 20:32

Try it without the pcmcia ram to see.

13 July 2012, 21:38

Sorry Spanner, The Alfa card will not work properly with Sram pcmcia card.

I guess you are trying to load a game via whdload. There is some weird conflict with the two.

Try the card without the pcmcia card present, and remove disable anything relating to it in the startup sequence.

Wb should work fine.

There is also some compatibility issues running kickstart 3.9 and Os 3.9.

Should be ok with the extra Zips when you get them.

In the meantime you could remove the FPU and see if this allows for the PCmcia sram to work with it.

spanner · 14 July 2012, 01:47

Some games are working and some are not,ah well have to get some more ram for it when I have the money.

spanner · 14 July 2012, 01:59

Oh one more thing dose this have a battery on it to save the date and time..?

Retrofan · 14 July 2012, 02:38

Here are the details and there a link to the manual: http://amiga.resource.cx/exp/alfaram1200 In german first, but later in english.

It says "battery backed up real time clock", but I don't see any battery. Edit: Oh, it must be the Varta one.

14 July 2012, 09:41

Yes there is a battery. Not sure if it still holds enough charge. It's the big beer keg looking object. Great to hear some games work.
