RE: HP97 The journey begins
Hi all,
Work has been slow with the 19C. I have been spending time assembling CPU boards and getting the Topcat ribbons out. I did manage to install the new memory chip and rewrite the interface code, so the available read/write cycles should last the life of the board. I also added a few software tweaks and apart from final printer testing it should be ready. Testing the printer is fiddly because the calculator needs to be fully assembled. If there is a problem, then it may need to be opened up again, which I don't want to do if I can help it. cheers Tony |
