The built-in font

The font is stored so that each byte is a column of the character. And stored so that the rom is read in incrementing order in order to draw the char.

Riteman Plus

There are (at least some) relations to Riteman+ plus printers:

• The DMP2000 accepts Riteman ribbon cassettes
• The shape of the case of DMP2xxx/DMP3xxxx series does resemble the Riteman models (although it isn't identical; the front of the Ritemans has a short horizontal edge, then followed by what looks like as a steeper diagonal edge - look at the photos to see for yourself)
• Unknown if the Riteman's internal PCB, mechanics, and Firmware do have relations to Amstrad models.
• According to the ACU review: the DMP2000 is "based on" the "Riteman F".

• Riteman C+/F+ from C.Itoh Electronics Corp
•

Add-ons

• The Dart Scanner for DMP-Printers from Dart Electronics is a add-on for DMP2000/3000 printers, the scanner optics are attached to the printer head.
• The DMP2000 Buffer Upgrade Kit from Goldmark Systems is a RAM expansion for DMP2000 printers.

Hardware Notes

The mainboard contains a uPD7811 CPU (marked "Amstrad 40036") with built-in 4K ROM, which contains reset/irq vectors and draft character set. Most of the actual program code and the NLQ character set are located in a separate 16K ROM/EPROM. The same mainboard (with additional ROM) is also used in DMP3000 models.
