As some of you may know, in the last couple of years since the pandemic, the price and availability of chips has been very challenging.
I really want to keep REX# both available and affordable! To that end, I have been searching for sources for parts. The great news is that I have been able to buy fairly large quantities of CPLDs and Flash memory to support REX#, and I am now very very well stocked. In other words, REX# will be available for quite a while. Also, I've invested in better test setups, and my cycle time to produce a REX# from parts to finished tested module is ~15min. REXCPM has different challenges. The CPLD used for this design is larger, and harder to find. Even worse, the price of SRAM has really shot up. For those modules, I'm actively looking for reasonably priced supply. So, still a bit of an ongoing struggle. The original voltage regulator was a part from Texas Instruments, and it appears to be no longer available. I recently found a new part that actually works a bit better, and this new part is readily available. So that's good. Also, I have found some acceptable 4MB SRAMs, and I've ordered a quantity of those. Happy holidays to all. Steve
