I have recently acquired an Atari 1040 STe with 1MB of RAM.
I read that you can extend its RAM with 30 pin SIMM up to 4MB. But it can be done only with 256KB or 1MB SIMM, and that 2MB, 4MB, 8MB and 16MB SIMM should not be used.
I have 6 30 pin SIMM but there are no stickers on them that tell me their size.
I have 2 models:
- 4 ones with 9 vertical chips marked "OKI Japan, M514100B-70SJ, 40222539A9Z", and there is written on the back of the modules "MSC23409B-70DS9 4041001, JAPAN";
- 2 ones with 3 horizontal chips marked "JAPAN A014, 9236 65NT, HM514400AS7", and there is written on the back of the modules "HB56G19B-7A, 9242 TT 13".
I don't want to damage my Atari 1040 STe by using modules with the wrong size, so how can I identify the size of 30 pin SIMM with those informations?
