We have also posted the CoreLift files here from wizged and will use your pic showing their use, if thats okay ?

No worries at all :-)

Arr some success at last, looking good

1. Your missing the Telcom 3.21 rom, that will also give you the Monitor. Next rom is the Calculator and Self Test.  You can them put in a couple game eproms in the other sockets.

As you posted later, they are in there. It's just all not very reliable. I also don't know enough about the system to use all the features yet. It did come up by accident once.

2. The coreboard connector pins & main board sockets, good idea to replace them with gold plated units.

Sigh. Not looking forward to that. I might try ordering a bunch of Machine Pin sockets and pins, for long term reliability. So much desoldering!

3. No cases commercially available, maybe you could draw one up from the artwork in the repo and get them 3D printed, but easiest would be get a gutted unit.  Also, check out the Super-80 Google Group as it uses the same keyboard and they are making new cases. Totally different to the Microbee case but its still a case that should work.

I'll keep my eyes open for a solution once I get this working.

4. Speaker should be 50 ohm, Microbee Tech has stock if one is needed.

Huh. I've fitted a pin header in that spot to make it easier to add and remove the speaker. I'll order one of those next pay.

5. Monochrome only unless a colour option has been fitted.  Only the Premium series units had colour built in.

I figured as much.

EDIT: The First 2 eproms on the left are BASIC, next is Wordbee (IC15) and next is Telcom (IC20) and next Calc/Self Test (IC25)

I see I have much work ahead of me. Thankfully with this much working, I have some momentum to keep going.


Cheers!
