I also have a 96KB from them for the card-reader port, and they also had 128KB and 160KB but I didn't have the budget for those. These all had lithium backup batteries so you could remove them (assuming they're FREEPORTed) without losing data. All front port modules (4K from HP, 32K, 64K from CMT) as well as Card Reader RAM modules (96K, 128K and 160K from CMT and 32K, 64K, 96K RAM, and 32K RAM/32K EPROM from HHP) have been sold on eBay in the last few years (sometimes bundled with a 71B), but they are all quite-to-very expensive - a lowly 32KB front port RAM module goes for anywhere between $100-200, usually towards the high end. Although this is still far cheaper than they were back in the day (e.g. 32K was $395), it's still high for hobby accessories! Garth - Do you have any idea where to get replacement Lithium batteries that fit the CMT front port 64K module? --Bob Prosperi |
