CleoRAM - improved GeoRAM - now available!

Post by rbernardo »

Francois “Eslapion” Leveille has developed CleoRAM – a clone of the classic GeoRAM cartridge… but improved.

CleoRAM (Compact, Lightweight RAM) specifications are:

CleoRAM capacities – 2 MB or 4 MB
Size – 5.8 x 6.5cm (same as original C= cartridge. Cartridge case not included.)
Weight – 30 grams
Battery for back-up – CR2032 lithium (battery not included)
Power consumption – 35 mA
Battery life – 3 years (estimated)
Edge connector – gold-plated
Compatibility – C64, C64C, C128, Ultimate 64

Price – $57 US (50 Euros) for the 2 MB version, $8 US shipping to US, 8 Euros shipping to Europe.
$90 US (77 Euros) for the 4 MB version. $8 US shipping to the US, 8 Euros shipping to Europe.

Contact – eslapion(at) or eslapion.fl(at)


by personal message at or

Paypal payments only to eslapion(at)

Details from Francois – This product works well on all C64, C64c, and C128 (1 Mhz and 2 MHz). also works perfectly well on the Ultimate 64, and it does support higher operation speeds up to 48MHz. Although the Ultimate 64 does already have GeoRAM emulation built-in, you still have the benefit of battery backup with CleoRAM.

CleoRAM (and GeoRAM) compatible applications are:

GEOS 64 (with appropriate Configure), GEOS 128 (with appropriate Configure), Wheels 64 (with Toolbox update), Wheels 128 (with Toolbox update), CP/M, GeoRAM Digi (C64), Funkpaint (C64), Volley for Two (C128) and the tools at ... -TOOLS.htm

and the games at ... -GAMES.htm

For other Leveille products (drive logic array substitute, PLA substitute, DRAM replacement board, TED expansion, VDC expansion, clock generator), go to COREi64 at ... ry&path=98

I wonder why GeoRAM clones are more popular than REU clones, which are virtually non-existent.
IMHO the DMA function of the REU was a very useful thing, and using modern electronics
the physical dimensions would be the fraction (even with 16MB RAM) of the original REU units
and the original C64 PSU would be able to handle the additional load, just like in case of the GeoRAM clones.
