If nothing has changed, I would be tempted to go for your option 3 (swapping). Here you kill two birds with one stone - Get better contrast and a metal case.

In relation to .. does anyone have a copy of snigfarp's barbarians
I don't use it myself but there is an account on twitter called PsiGamer, this looks like his 'space' - again the link to the - psigamer.cyningstan.org.uk - page is broken and the twitter account looks dormant but maybe one of his 'followers' might have a copy of the barbarians for you. There is a mention of it October 2015.
on never mind worked it out. it was needing to set handshake on the psion to xon/xoff.

I recently (2 days ago) managed to get a commslink. it's a 4.2 rom 25pin. I am using win10 & a usb to serial cable and although I can use terminal on the psion to talk to putty on the win10 machine perfectly but i can't transfer files no matter what I try even following the instructions . i've tried psi2win but it just sits there saying waiting for link and times out on the psion and basically the same thing using cl in dosbox. I was first using a usb to serial cable that used prolific chip but saw that might be problematic so swapped out to another that I don't think uses prolific (it's a dtech but can't find specs for it) and same thing, terminal is fine but file transfer just doesn't seem to want to work.
