| My 1989 SOC shows that the 3540 needs
MS60-AA 8Mbyte modules
MS60-BA 16MByte modules
The 1991 SOC shows there was an MS60-CA 32Mbyte module, with 3 memories
max depending on the configuration.
The 3500 was before my '89 SOC....

| Hi John!
Carrying on from Dave? Glad you stepped up to bat!
As for the MS650, on the 3500, you can only have a maximum of 4 memory
boards due to the private CPU-Memory bus. Here are the capacities you were
looking for:
MS650-AA 8MB RAM MEMORY ARRAY FOR KA650 (M7621-BA)
MS650-BA 16MB RAM MEMORY ARRAY FOR KA650 (M7622-AA)
MS650-BF FIELD INSTALLED 16MB RAM MEM ARRAY FOR KA650 (M7622-AA)
Some others...
MS650-BC 32MB RAM MAEMORY ARRAY FOR KA650 (M7622-CA)
If you could get 4 MS650-BC, that would take you to 128mb.
Good luck with the project!
Regards,
David Fox

| Thanks for the replies.
If anyone has some spare Firefox memory they want to contribute to a good cause,
please let me know!

| 4346.4 | 64 MB max total for MS650s | KA680::CULLISON | | Tue Feb 04 1997 09:47 | 4 |
| A MS650 memory that has 32 MB capacity is taking up effectively 2
slots even though physically it is in one. Maximum memory size is 64 MB
here period. You cannot get to 128 MB.

Don't forget that you need to have a funky 5-"drop" cable to be able to
support 4 memory cards and the 3500 CPU. Don't have the number at
hand, or I'd post it.
As for better Firefox info, sorry, I can't seem to recover the
notesfile from the backup of the cluster it resided upon. There is NO
system bus correlation between the 3500 and the 3520 CPUs. The 3520
uses special memory, in 8, 16, and 32MB flavors. Depending on your
configuration, you could have up to 128MB, but I think that you'll
limit your configuration possibilities (only 1 cpu, only 8-plane
graphics, only 1 IOP). Still, 128MB isn't a lot to sneeze at for
a small workstation (hey, we're talking late '80s tech).
I'm still trolling for help with those backups. I've tried a number of
different 8mm drives with different results (some drives read SOME
tapes, others only read one, etc). It's frustrating to have info that
you can't access.

| Unfortunately, I only have a single-density Exabyte drive to offer, and I'm sure
you've found one of those.

Yup, it's probably been in the list. I'll see if I can find the
listings files from the tapes that I have read; the others I'm not
really sure if they've been init'd or I just am not holding "things"
the right way. I've been amazed how sensitive the 8mm drives seem to
be to alignment (I had thought that this was not supposed to happen
with helical scan). Drat.

RE:3
John
if you still some spares for the Firefox send me a mail message, there
were a few laying around CX03 waiting to go to scrap.
