Bally Astrocade enthusiasts Ken Lill and Mike White have just unleashed an amazing surprise on the Bally Astrocade community--a memory expansion unit for all of the extended memory games that were previously only playable with an expensive and very rare (even then) early 80's expansion unit. Bottom line, until this release, only a handful of people in the world have been able to play extended memory software on the Bally Astrocade, a system that greatly benefits from that option.
Here's a snippet of the initial press release from Ken Lill (pricing withheld by me at this time, but it's very reasonable):
This is a true 32K expansion unit that uses a "floating" type of memory.
It starts @ 5000 Hex and goes to CFFF Hex
However, the 5000 Hex area is also the D000 Hex area, 6000 - E000, and 7000 - F000
