DMP2000 Buffer Upgrade Kit
From CPCWiki - THE Amstrad CPC encyclopedia!
The Amstrad DMP2000 Printer 8K Buffer Kit from Goldmark Systems is a RAM upgrade for Amstrad's DMP2000 printer.
The "kit" seems to be simply consisting of a 8K SRAM chip, to be used as replacement for the printers built-in 2K SRAM, increasing the buffer size by 6K. Aside from exchanging the RAM chip, one must also change the J3 jumper on the PCB (as shown in [[Image:DMP2000 Schematic.png|DMP2000 Schematic).
The upgrade should also work with the DMP2160 printer (a faster version of the DMP2000, which has only 2K RAM built-in, too). The DMP3000 and later models do include 8K RAM built-in, so there's no need to upgrade them.
