I'm not well versed in all things Apple // but given the prospect of sourcing multiple 4116 DRAMs for either troubleshooting, repair or upgrading to 48K, are there alternatives? 4164 DRAM ICs (modified) can work as far as I know (happy for anyone to chime in on the "gotchas" of this). I've repaired a few ZX Spectrums using complete "lower" and "upper" ram boards where a PCB covering the entirety of the bank of RAM, connected via machined pins to the emptied RAM sockets, carry an SRAM based module and some supporting components. Is there anything like this for the // and //+ ? I realise the original aesthetic is lost with this approach.
