Installing ZIP Memory
Install disk and manual thx to Moussa!
Hypertec Hyperam 50/60 (2 MB version shown)
![[P]](/other/img/photo.gif "Front")
BANKxx Sockets for ZIP DRAM
DL AD14AA200 200 ns delay line
U15-17 CY2149-35PC 1Kx4 SRAM
The rest of the board is populated with 74xx logic and PALs. No ASICs.
The layout of the 8 MB board appears to be largely identical to the 2 MB
variant, aside from the different DRAM sockets (20-pin vs 16-pin) and one
additional DIP IC next to the delay line.
Installing ZIP Memory
Two versions of the adapter exist — a 2 MB and 8 MB:
- 2 MB version [@7057?] has 16-pin ZIP sockets and uses 256Kx1 ZIP DRAM chips (M5M4256AL-10 or compatible) for 512 KB, 1 MB, or 2 MB total.
- 8 MB version [@7017?] has 20-pin ZIP sockets and uses 1 Mbit ZIP DRAM chips (type unknown) for 2 MB, 4 MB, or 8 MB total.
The used devices must be 120 ns or faster. You may use 100 ns chips (-10)
but you will obtain no speed benefit.
Valid combinations:
- One Bank Filled - [0H/0L]
- Two Banks Filled - [0H/0L], [1H/1L]
- Eight Banks Filled - [0H/0L], [1H/1L], [2H/2L], [3H/3L]
