9 | The Ethernet chip is a CrystalLan CS8900A-CQ3, | ||
10 | a 10Base-T LAN chip. | ||

12 | There is an empty, 26 pin port labelled 'Motorola BDM Port'. | ||
13 | Motorola BDM stands for Motorola Background Debug Module, | ||
14 | so we might speculate that this port allows us to perform | ||
15 | debugging on the HD24 as it is running. | ||
16 | |||
17 | There are to IC41LV16256 chips in the HD24: according to the | ||
18 | data sheets, they are 256kx16 bit Dynamic RAM with EDO page mode, | ||
19 | giving the HD24 a total of 1 megabyte of RAM. | ||
20 | |||
21 | There is an ALTERA ACEX EP1K30QC208-2 | ||
22 | FPGA (Field Programmable Gate Array). | ||
23 | |||
24 | There is a Texas Instruments AHCT16541 | ||
25 | AHCT16541 devices are noninverting 16-bit | ||
26 | buffers composed of two 8-bit sections with | ||
27 | separate output-enable signals. (possibly | ||
28 | used for communication to displays?) | ||
