Paul,
A couple of years ago I did design and build a new daughterboard with
modern SRAM that supports up to 2 MiB of RAM on the PC/380 and up to 512
KiB on the PC/350. https://oshpark.com/shared_projects/eBNkBw8x
Cool!
It even works.
;-)
I never made a push to publish it because by the time
I got to it the
parts (Cypress CY62167G-45ZXI SRAM and ATF1504AS-10AU100 CPLD) had
become unobtainable.
The SRAM can still be find, but the CPLD?
Any chance to replace it with something newer?
Maybe things have changed, but right now there are
only 3 of these
boards. I have 2 and I think I sent the 3rd to you, Paul.
Any chance you like to have a look at it again?
