Compupro Godbout ECONOROM 2708 EPROM Board S-100 Computers. Selling as-is (untested). Looks to be missing Chips. Please see photos.
This board provided space for up to 16 2708s, one of the most popular high density EPROMS at the time. EPROMS give the advantage of retaining stored data when power is removed. EPROMS are erasable; that is, after programming they may be erased and reprogrammed with other material. The EPROM locations on this board are... grouped in four independent 4K blocks. The on-board DIP switch (no jumpers required) provided addressing on any 4K boundary Additionally, each 4K block contains an independent disable switch. This board also featured a wait state selection switch to select zero or one wait state, provision for use of PHANTOM input (line 67), a switch addressed power-on-jump feature, thorough capacitor bypassing of supply lines to Suppress noise transients, plus on-board regulation and heat-sinking for reliably cool operation.
