The first question I would be asking myself is "What do I want to achieve with upgrading?"
You need to set a a target before you spend too much time on how to get there.
The second question is "will this improve the attractiveness to a potential buyer or detract from it?"
Lastly "Will the cost outweigh the improved resale value?"
Assuming the keyboard is working well my top items for improving resale value would be.
A) Upgrade to 13.5Mhz (from the current 12MHz which will require a new Character ROM on the mainboard (which will be needed if you go to a later BASIC anyway), as well as a new crystal and some board mods..
B) Adding deglitch to get rid of those black streaks from the screen.
C) After the above, then look at other possible Coreboard changes that would be attractive (Do I aim for a gamer or programmer as a buyer?)
Hope this helps

Thanks for your reply Ernest, some good points.
When I re-sell a computer, and especially when people are paying premium prices, I always want it to be in the best condition possible ... none of this "no cables, can't test, dunno" and the images show it caked in grime because they haven't bothered to even give it a wipe down (argh).
I want the new owner to be able to actually use it - power it, connect it to a screen, load software (if nothing in ROM) ... the plan ... hope ... is to at least break even

We had an Amstrad growing up, and Apples/XTs at school, so never had much hands on with Microbees, although they always fascinated me.
So it's good to hear about those improvements I could do.
Like someone mentioned about new core boards, had anyone made (i.e. PCB files available) a modern/simplified replacement that can take 32KB SRAM and 2764/27128 ROMs?
Brett.
