+OLD CS1 Posted August 18, 2020 Share Posted August 18, 2020 CMD made the 1750XL, and GGLabs makes a GeoRAM-alike, but I have not seen an REU replacement made in the modern era. Is there one somewhere? Quote Link to comment Share on other sites More sharing options...
Badaboom Posted August 18, 2020 Share Posted August 18, 2020 The U2+ includes a REU. 1 Quote Link to comment Share on other sites More sharing options...
brain Posted August 18, 2020 Share Posted August 18, 2020 Not a standalone unit. U64, 1541U, and Chameleon offer REU capabilities, though. I do actually know of 2 standalone projects aiming to bring a small REU to fruition, but nothing to sell, yes Quote Link to comment Share on other sites More sharing options...
+OLD CS1 Posted August 18, 2020 Author Share Posted August 18, 2020 Pretty much what I thought. Thank you! I have a U1541-II, I just have not had a chance, yet, to try it out due to injury. I did not think the DMA controller would be too difficult to replicate. Quote Link to comment Share on other sites More sharing options...
motrucker Posted August 21, 2020 Share Posted August 21, 2020 There's an old school option. I just bought one of these: https://www.ebay.com/itm/Commodore-64-128-Beyond-512k-Upgrade-PCB-For-1764-1750-RAM-Expansion-Unit-REU/383676971191?hash=item5954edf8b7:g:V7wAAOSw379cZqCI And am ready to modify a spare 1764 I have. Having 2Mb available isn't to shabby. Quote Link to comment Share on other sites More sharing options...
+OLD CS1 Posted August 21, 2020 Author Share Posted August 21, 2020 I have one of those kits, I just never got around to installing it. I have a 1750 and a 1764 I upgraded to 512k back in the 90s. Quote Link to comment Share on other sites More sharing options...
