- I am having trouble with adding memory to my 520 STfm.
- Everything is connected according to the instructions (From the
- Umich Atari archives) but the upper bank of memory will not respond.
- I remember that someone mentioned a few additional modifications
- needed to be put in. I noticed that the CAS1 High and CAS1 Low
- lines require resistors along with the RAS line. But, what values
- must be used? Besides that, I can't think of anything else but a
- faulty MMU. I believe that a person named Annius Groelink? knew
- what to do, but I do not have full Internet access so I can't
- find the E-mail address.
- One other question is: can I use Mac SIMMs for the ST
- mod since they have an 8 bit data bus, (and are considerably
- cheaper!!).
- Thanks in Advnc,
- George II Lenzer
