Inside the printer is a 4-cell AA battery pack, which I intend to replace (as with the last one) with a pack from Amazon that's already on the way. The new pack is 2000mAh (at 4.8v). The original, 42 year old pack? 450mAh (at 4.8v).
I also discovered that battery corrosion carries through copper wires.
I somehow became addicted to repairing 80s Pocket Computers. These things are quite interesting - ahead of their time, a bit... This first model was made in 1980. Yes, 42-43 years old. Has a pocket sized dot-matrix printer.
The TRS-80 Pocket Computer (retroactively named PC-1) is a rebadged Sharp PC-1211; I fixed the PC-1 first, now time to fix the PC-1211 version.
This is the second one I've done. #retrocomputers #tandy
@TechConnectify I paid $150 for it new on craigslist lol
It's definitely a tech that manufacturers seem to be hiding/not wanting to promote -- like portable heat pump units (also which I have/use/love).
@astrr or buy on Bandcamp and keep it. also generally most any other site you can actually download your purchased content from, comes DRM-free.
You can have both: supporting artists as well as having a permanent collection you own :)
