If so, do you have some ideas ?
How have you configured the dip switches on the ast board? What banks are populated.
The memory can be used as base memory and EMM depending on how it's configured.
2mb sounds like it was probably configured purely as EMM, which could be useful for software like 123 (EMM was created by Lotus, Intel & Microsoft). EMM is banked ram that only is supported by specific software packages.
