restoring a Series IIx

2007-11-28 by dvdborn

Hi,

I've taken upon me the daunting task of restoring a Series IIx. 

When it went into storage it was still working fine. But that was before the battery decided 
to spill its acid all over the CPU control card.

I'm guessing that someone else already has done some work on the card since it seems 
that some chips are missing. Or is it normal that some sockets on the board are not filled?

I've uploaded a picture of the card here:

Can anyone else please post a picture of their CPU Control card so I can compare the 2?

I hope I get this IIx going again. It will give me the chance to own it for a substantial 
amount of time and play with it.

BTW, I'm not a qualified technician but I restored my own Emulator III some time ago and 
that went well.

Cheers,
David

Hi (bonjour ?)

David,

This picture is bad :( bad day for this Q133 ;)

Normaly in Q133(my is R6-CR) you found these chips in location :

D5,6 you found 2x16 EPROM with F8LMRK5
C5,6 you found 2x16 EPROM with Q9FGMRK1

ou found the bin file of this eprom here :
http://egrefin.free.fr/eng/fairlight/cmi2xEpromsE.php

C10 74LS97
C9 74LS158
C8 74LS74
C7 74LS174

C4 74LS03
C3 74LS00

CRYSTAL is SKY 1.8432 MHz


bonne chance ;)

Bonjour JB,

(Flamand, mais je me débroulle bien en français :-))

Thanks for the info. 
Luckely I own an EPROM writer so I'll be ordering those Eproms and I hope that the other 
components (74L...) are still easy to obtain.

Lots of work to do...

BTW, thanks for making the EPROM images available.

Cheers,
David
