COMSPEC 2MB Sidecar A1000 Expansion - Issues?

[troupe86]

Hi folks,

I recently sold a completely working Comspec 2MB sidecar RAM expansion on eBay and it ended up going from Ireland to Australia.

The buyer claims that it boots only to a white screen when the RAM is inserted. Can sidecar RAM cause this issue if it's supposedly faulty?

They have stated that their A1000 boots without it and they have cleaned the expansion slot on the side to no avail.

They did mention that the previous owner installed a KS ROM switch mod between 1.3 and 2.0, internal/external floppy switch mod, and some internal RAM upgrades (they may be talking about the stock RAM daughterboard), but they also claim that they don't know much about it.

Do you think they are trying to pull a 'fast one'? It was definitely well wrapped in lots of bubble wrap and was boxed before it left.

It might be a conflict with the Internal RAM Expansions, although I never had any problems with a Rejuvinator board, an SA1000 SCSI Card and 2 AX1000 2MB Expansions. If just using a standard A1000 the Ground Modification is highly recommended. If using Multiple Side Expansions use the Ax1000 first.

Since I worked for Comspec and have the Technical Notes on most of the Devices, if I know what internal expansion are in use i might be able to help further.

Thanks for the reply! I'll try to find out what the other person has in their A1000. They haven't been too specific but I suspect they aren't entirely sure themselves.

I can definitely confirm that the RAM expansion worked on my A1000 and all I had was the internal standard daughterboard RAM and front RAM cartridge.
