Atmel avr ATTiny2313, ATTiny4313, AT90S2313, AT90S1200

For all the above, you will have to change the reset circuit
(pin 1 of mcu to 4K7 to VCC and 10uF capacitor from reset to gnd).

I think AT90S2313 & AT90s1200 was obsolete. Reset is available in the market

89S2051 does not have eeprom, the OP specifically asked for that.

the chip has flash rom, and ISP facilty. The O P is asking for isp facility. To what i understand 89c2051 cant be programmed unless you have a parallel port programmer and Vpp.
He , perhaps means flash ROM. Don't look at specific "EEPROM" that he mentioned.
