A501+ expansion (rot projekt)

Post by _bigdan_ » Sat 8 Apr 2017 12:34

Anybody here with a classic A500+ with "red A501+ memory expansion" from "Rote projekt" (red A500+ motherboard kit by Scrat and Matze, cf on A1k.org forum) ?

My A500+ has only 1 Mb and, as Elbox 500+/1 or Microbotics A502 became rare in 2017, it would be a good alternative... I have'nt yet my V500 V2+ but my old A500+ is nearly ready to make a time jump ;-]

Or perhaps Kipper2k have yet in stock thos model http://www.kipper2k.com/a500chip.html ?

Yes, I bought one along with the full A500+ MB and I started out assembling the 1MB expansion and tested it in my standard 500+. As expected, it works just like any other 1MB expansion, so if you have the skills to solder it, go ahead and get one.

Alternatively, you can also go really cheap and get this DIY kit if you have some old EDO memory modules lying around that you can steal some ICs from:
