Another fundraiser..

This fundraiser is multiple lots we have been offered for our museum, most of these are extremely early systems, and many contain unreleased games and history that would other wise be lost.

The goal for this is split into groups, we have awhile to sort this one and lots would be paid as funded. The total includes paypal fee's added and shipping costs included excluding taxes, we put 10% as we're often charged different rates depending on donators locations.

yesterday I was sitting in VK.COM and saw a person asking what this inscription means on VMU
avito-1633534133434-shot.jpg

some time ago I was presented with a VMU in which several pixels on the screen are damaged and two buttons are missing (B and MODE), I decided that the time had come to restore this VMU, but this is not enough, I am not ready to buy batteries in batches, so it was decided to modify the VMU with a rechargeable battery

1) remove IC5
2) Remove D5 and solder pins together
3) unscrew the positive contact and screw in the self-tapping screw without it
4) cut off the negative contact along the bend
5) glue the battery with two-sided tape to the board
6) stick the charging controller to the battery on two-sided tape
7) solder ground to the charge controller and to the battery
8) solder plus to the charge controller (BAT +) and to the battery (B +)
9) solder the wire from pin 2 (+ 5V) or CE1 capacitor to the charge controller (IN +)
10) cut out the battery compartment in the case

TP4056 charge controller, micro usb connector must be removed

The Li-ion battery was sized according to the size, I took a 150 mah battery from cheap wireless headphones

remove either with hot air or with a soldering iron diluting with a large amount of solder

Just tried this and not working for me.
Probably done something stupid 🤣

It’s charging when plugged into Dreamcast but no life when unplugged.

Bat+ to battery +
Bat - to battery -
In + to cap
In - to ground
D5 soldered together

Am I missing something?
