- Sorry if I`m wrong, but this explanation sounds like you`ve put them in a
- strange configuration.
- Just to be sure, from below they`re set 16,4,4 ?

- I found out that several of the jumpers weren`t very good, especially after
- placing them several times.
- And the Module seems to have trouble if it has to supply a bit more
- current.
- A single SIMM-Shuttle (for example) worked as long as the module didn`t get
- too warm.
- But when I tried to use 2 of them (for 32MB at that time) it produced nice
- errors (gfx-display got corrupted while working, data was changed in mem
- etc.) which became worse the longer the machine was on.

- No prob... I`m using 60n and 70n with not prob at all, so this isn`t
- (surely) the fault.
- But have you EVER tried to use the SIMM in another machine - even a PeeCee
- would do (in fact, that`s one of the best things it can be used, though -
- the only work you won`t need a P5-999MHz :))
-
- >Anyone ever heard of such a strange problem before?
- Sorry, I had some troubles in my config, too, but these are (VERY STRANGE!)
- coming and going and belong to the SCSI part (SCSI hangups).
