From a56e4ddcdf52bc82ef147ed3f307db2279bb73f0 Mon Sep 17 00:00:00 2001 From: ClawGrip Date: Wed, 8 Dec 2021 01:34:46 +0100 Subject: [PATCH] dec0.cpp: Correct note about DEM-01 [Caps0ff] (#8942) It's a Fujitsu MB8421 Dual port SRAM. Since it's a supported device (src/devices/machine/mb8421.cpp), maybe it should be correctly hooked up on the driver. --- src/mame/drivers/dec0.cpp | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/mame/drivers/dec0.cpp b/src/mame/drivers/dec0.cpp index f16424464af..da0ef944a5f 100644 --- a/src/mame/drivers/dec0.cpp +++ b/src/mame/drivers/dec0.cpp @@ -312,7 +312,7 @@ DE-0316-4 | PZ-2.A2 | |-------------------------------------------------------| Notes: - DEM-01 - Unknown SDIP52 ASIC (no clock input so not an MCU, decapping it found only ASIC, no ROM) + DEM-01 - Fujitsu MB8421 Dual port SRAM in disguise as Data East custom chip DEM-01.
