Ebay Board 3: The 1MB upgrade

Post by Elethiomel » Fri May 13, 2022 8:46 pm

Nothing too exciting here, but I did document it just in case it went horribly wrong.

First, we need to desolder
16 * 15 IC pin holes = 256
16 * 2 capacitor holes = 32
3 * 2 resistor holes.

That's a grand total of 294 holes. Great fun.

Here we are part of the way through the process

That took a while, but finally, it's all done.

Caps all in place

Sockets in place.

Resistors in place. Weird reflections. The joins are actually a lot better.

Chips in

Detected and testing well

Nothing that complicated. It was rather time consuming, but I wanted to keep this system fairly conservative and not all tricked out. No boosters. No floppy emulators. I plugged in a joystick and had a nice fun game of New Zealand Story off of an original floppy. :)

Good job :) Reminds me of trying to sell a 1mb STFM on ebay/fb recently, people telling me it wasn't worth anything because it didn't have 4mb. Stupid idiots honestly, 1MB will play 99% of all commercially released games. If I spent the money on upgrading it to 4mb then adding the costs of the upgrade & labour into the price it would have been even less likely to sell. the irony ;D.
